PART 1. SYSTEM OVERVIEW

1.1 INTRODUCTION

DCS-816, Digital Communication System, is a digital telephone system designed for small tomedium-sized businesses. The system employs the very latest Digital Signal Processors (DSP)technology.

DCS-816 is easy to install and maintain, convenient to use and provides a variety of features,including advanced ones such as ISDN and CTI.

DCS-816 provides some interface cards that allow connection to the public telephone network orprivate networks. These are generally referred to as trunk cards. Besides the trunk cards, itprovides some option cards for serial interfaces and the Auto Attendant feature. Two types oftelephones can be connected to the system: proprietary digital phones called "Keysets" connect todigital line interface (DLI) ports; standard telephone sets, generally called "single line telephones,"connect to single line interface (SLI) ports. In addition, DLI station ports are used to connectperipheral devices such as door phone interface modules (DPIMs) and CTI interface modules.Miscellaneous circuits are provided to allow such optional features as external paging, music onhold, background music, general-purpose dry contact and emergency power failure transfer.

All DCS keysets utilise a single PCB with surface-mounted components assuring the highestproduct quality and long life. Samsung's customary large, easy-to-read displays and LEDs in thebutton (key) design make them much easier to use. In many instances, sophisticated features aremade simple through the use of friendly display prompts or push-on/push-off feature keys.

NOTES:1. 'DCS' is the general term used in the text to refer to Samsung digital systems. Any differences

between the systems are indicated under separate headings ‘DCS’, 'DCS Compact', 'DCSCompact II’ and ‘DCS-816’.

2. It is not possible to expand from DCS-816 to other DCS systems.3. DCS-816 cannot accommodate cards from other Samsung digital systems except for the DCS

Compact BRI card.

1.3 TECHNOLOGY

SWITCHING

System switching is accomplished by means of a custom IC "engine" that provides 256 switchabledigital channels. The engine is controlled by its own 16-bit Motorola MC 68000 microprocessorand switching control program. Each of the 256 digital channels is automatically assigned to carryvoice or data as required by system operation in a PCM format.

In addition to the 256 channels mentioned above, the system also utilises Digital SignalProcessors (DSPs). Each DSP may be configured by the switching control program as a DTMFsender, a DTMF receiver or as a C.O. tone detector on a per-call basis. DCS-816 is equipped withone engine chip which contains four (4) DSP channels.

The DSP channels are fully shared throughout the system as a common resource.

MEMORY

The systems operate using stored program control. This program is stored in EPROM chips. Allspecific customer data is stored in random access memory (RAM) which is protected against theloss of AC power to the system by an on-board battery backup system.

MICROPROCESSORS

DCS-816 uses distributed processing. The primary system processor is a 16-bit Motorola

MC68000 operating at a clock speed of 8 MHz. Secondary processing is done in some specialcards, such as BRI, and also in the keysets. The digital keyset uses a Hitachi H8 processor fordata communication within the DCS-816.

1.4 PROGRAMMING

DCS-816 is self-configuring. This means that when the power is switched ON, the system readsthe types and locations of all installed cards and telephones and assigns default data to them. Thisdata provides for system operation within seconds after power is switched ON. All trunks andstations are assigned according to the default numbering plan. This numbering plan is flexible andmay be changed to suit customer requirements. The installing technician customises thesedefault data to meet the end user's requirements.

The systems can be programmed from any LCD display keyset without interrupting systemoperation. There are three levels of programming: technician (or system), customer and station.The technician (system) level has access to all programs and can allow the customer access tosystem programs as needed. Technician and customer access is controlled by different securitypasscodes and access procedures.

DCS-816 also allows the use of a proprietary computer program called PCMMC. This permits atechnician to program the system using a personal computer. PCMMC can be used on-site tomodify the customer database or to download (save) the entire customer database to a file. Thisfile can then be saved as a backup and be uploaded when required to restore the database.


1 - 8

Through the use of modems, PCMMC can access a DCS-816 system remotely (off-site) to makedatabase changes or perform uploads or downloads of the customer database as if the technicianwere on-site.

4.2 SYSTEM FEATURE DESCRIPTIONS

Account Code Entry

Station users may enter an account code (maximum 12 digits) before hangingup from a call. This account code will appear in the last column of the SMDRprintout for that call record. Keyset users may enter this code using an account(ACCT) key without interrupting a conversation. Single line telephone usersmust temporarily interrupt the call by hook–flashing and dialling the featureaccess code. Account codes can be up to 12 digits long.

l ForcedWhen forced, account codes are always verified from a system list of 200entries. Account codes are always printed on the SMDR report. They cancontain digits 0–9.

l VoluntaryUsers may select to enter an account code for any call. Digits can include0–9, star (*) and #.

All Call Voice Page

Users can page all the internal and all the external paging at the same time bydialling the All Page code. Keysets may be restricted from making or receivingpages in system programming.

Attention Tone

To get your attention, a brief tone precedes all page announcements or intercomvoice calls. There are separate programmable duration timers for page andvoice announce tones.

Authorisation Codes

Authorisation codes are used to give permission to make a call. These four digitauthorisation codes can be either forced or voluntary. When used, authorisationcodes will automatically change the dialling station's class of service to the levelassigned to the authorisation code. Authorisation codes may or may not beprogrammed to print on SMDR.

l ForcedWhen a station is programmed for forced authorisation the user mustalways enter this code before dialling is allowed. The dialled authorisationcode is verified from a system list of 30 entries.

l VoluntaryAny station user can always enter an authorisation code before they begindialling. The dialled authorisation code is verified from a system list of 30entries.

Auto Attendant

The integrated digital automated attendant option provides four ports per AAoption card. One AA option card per system. Sixteen professionally recordedprompts inform callers of the progress of their calls. Some examples are: "I am


4 - 3

sorry. There is no answer", "That station is busy" and "Invalid number. Please tryagain". Two minutes of battery–backed random access memory (RAM) provideup to 48 customer recordings for announcements or greetings. Twelve individualgreeting boxes, each with its own dialling options, allow you to build call routingbranches as needed. Callers are routed through the branches by diallingextension numbers or single digits.

NOTERequires optional hardware and/or software. Ask your dealer for details.

Automatic Hold

While a keyset user is engaged in an outside (C.O.) call, pressing another trunkkey, route key or CALL key automatically places the call on hold when thisfeature is enabled. Pressing TRSF, CONF, PAGE or a DSS key alwaysautomatically places a C.O. call on hold. Intercom calls can be automaticallyheld only by pressing TRSF or CONF. Each keyset user can enable or disableAutomatic Hold.

Background Music

Keyset users may choose to hear music through their keyset speakers. Eachuser may adjust this level by the use of a volume control program at the selectedkeyset.

Branch Groups

Each station can assign its branch group. There are 8 branch groups in DCS-816. When incoming or intercom call is ringing on station, any other stations thatincluded the same branch group can answer by lifting the handset or pressingthe speaker or ANS/RLS key.

Call Forwarding

This feature allows the user to redirect (forward) incoming calls. The calls can beredirected to the attendant, a hunt group, voice mail, external number or anotherstation user. If the destination station is in Do Not Disturb (DND) mode, thecalling party will receive DND/NO MORE tone. Calls cannot be forwarded to adoor phone.

l All CallsThis type of forwarding is not affected by the condition of the station. Allcalls are immediately redirected to the designated destination. If desired,the destination station may redirect the call back to the forwarded stationby using the transfer feature. The forwarded station user can continue tooriginate calls as usual. If no key is programmed as Forward All, the TRSFkey lights steady when a forwarded all condition is set.

l BusyThis feature forwards all calls only when the station set is busy. The stationuser can originate calls as usual.

l No AnswerThis feature forwards calls that are not answered within a preprogrammedtime. The user can originate calls as usual and receive calls if present. The


4 - 4

timer is programmable on a per–station basis to allow for differences inindividual work habits.

l Busy/No AnswerThis feature allows the station user to use both types of forwardingsimultaneously, provided the destinations have already been entered in theusual manner.

l Follow MeThis feature allows the station user to forward all calls from another stationto the user's station or change the forward destination to the user's currentlocation.

l ExternalThis feature forwards C.O. calls to an external number via a central officetrunk if allowed by class of service. These C.O. calls forward only after theprogrammable external call forward delay timer expires.

l To Voice MailEach station may be programmed to allow or deny the ability to forwardintercom calls to voice mail.

Call Hold (Exclusive)

Outside calls can be placed on exclusive hold at any keyset by pressing theHOLD key twice during a call. Calls placed on exclusive hold can only beretrieved at the keyset that placed the call on hold. Intercom calls are alwaysplaced on exclusive hold.

Call Hold (System)

Outside calls can be placed on system hold at any station. Users may dial theaccess code or press the HOLD key. Calls on system hold may be retrieved atany station.

Each C.O. line has its own park zone. This simple method eliminates confusionand ensures that a park zone is always available. Pressing the PAGE key parksthe call automatically. There are no extra keys to press and there is no lost timelooking for a free zone.

Call Pickup

l DirectedWith directed call pickup, users can answer calls ringing at any station bydialling a code plus that station's extension number/incoming trunk numberor by pressing the feature key and then dialling the extensionnumber/incoming trunk number. You can pick up not only incoming andintercom call, but also hold recalling call if allowed.

l Groups (8)In addition, calls can be picked up from a station group in a similarmanner. The group pickup feature allows users to answer any call ringingwithin any pickup group. There are 8 pickup groups available. A stationcannot be in more than one pickup group. To use this feature, station


4 - 5

users either dial the access code or press the assigned feature keyfollowed by the pickup group number. You can pick up not only incomingand intercom call, but also hold recalling call if allowed.

Call Waiting/Camp–On

Busy stations are notified that a call is waiting (camped–on) when they receive atone. The tone will be repeated at a programmable interval. Keysets receive anoff–hook ring signal through the speaker and single line stations receive a tonein the handset. The volume of the camp–on tone can be set by the station user.Camped–on calls will follow Forward No Answer if a Forward No Answerdestination has been set.

Chain Dialling

Station users may manually dial additional digits following a speed dial call orchain together as many speed dial numbers as are required.

Class of Service

The system allows a maximum of 10 station classes of service. Each class ofservice can be customised in memory to allow or deny access to features and todefine a station's dialling class. Each station can be assigned different classesof service for day and night operation.

CLIP (Calling Line Identification Presentation)

The CLIP feature is dependent on having an LCD keyset to show the name ornumber in the top line of the display.

l Name/Number DisplayEach LCD keyset user can decide if he/she wants to see the CLIP name orCLIP number in the display. Regardless of which one is selected to beseen first, the NND key is pressed to view the other pieces of CLIPinformation.

l Next CallIn the event that you have a call waiting or a camped–on call at yourkeyset, you can press the NEXT key to display the CLIP informationassociated with this next call in queue at your station. Either the CLIPname or CLIP number will show in the display depending on your NNDselection.

l Save CLIP NumberAt any time during an incoming call that provides CLIP information, youmay press the SAVE key. This saves the CLIP number in the SaveNumber feature. Pressing the SAVE number redial key will dial the CLIPnumber.

l Store CLIP NumberAt any time during an incoming call that provides CLIP information, youmay press the STORE key. This save the CLIP numbers as a speed dialnumber in your personal speed dial list.


4 - 6

l Inquire Park/HoldHaving been informed that an incoming call is on hold or has been parked,you may view the CLIP information before you retrieve the call. This willinfluence how you choose to handle the call.

l CLIP Review ListThis feature allows display keyset users to review CLIP information of callssent to their stations. This list can be from 10 to 50 calls on a first–in, first–out basis. The list includes calls that you answered and calls that rang yourstation but that you did not answer. When reviewing this list, you can pressone key to dial the person back.

l InvestigateThis feature allows selected stations with a special class of service toinvestigate any call in progress. If CLIP information is available for anincoming call, you will know to whom this station is speaking. On outgoingcalls, you can see who was called. After investigating, you may barge–inon the conversation, disconnect the call or hang–up.

l Abandon Call List (100)The system has a system–wide abandon call list that stores CLIPinformation for the last 100 calls that rang but were not answered. The listis accessed using the operator's passcode. While reviewing this list, youare provided with options to CLEAR the entry or DIAL the number. Youcan use the NND key to toggle between the CLIP name, CLIP number andthe date and time the call came in.

l CLIP On SMDRThe Calling Line Identity of the calling party for each call, and the callingparty name from the Translation table (if one has been entered by theuser), will be printed on the SMDR record of each call.

l Number To Name Translation (200)The system provides a translation table for 200 entries. When the CLIPnumber is received, the table is searched. When a match is found, thesystem will display the corresponding name. This allows users in areasthat do not support deluxe CLIP to provide names for regular callers.

Common Bell Control

DCS-816 provides a dry contact to control a customer–provided common bell orcommon audible device. This contact must be programmed as a member of astation group and may provide steady or interrupted closure.

Computer Telephony Integration (CTI)

Computer Telephony Integration (CTI) allows integration between the DCS-816and a personal computer system (PC). Caller ID service is required on TAPIinbound call applications that use the CLIP information to display computerrecords in conjunction with the presentation of the call to the station on the DCS-816 system. TAPI is described below.

l TAPIJointly developed by Intel and Microsoft, TAPI (Telephony ApplicationsProgramming Interface) delivers telephony features to the Windowsdesktop. TAPI is an open application interface (OAI) protocol that supports


4 - 7

First Party Call Control. A DCS-816 Computer Telephony Module (CTM) isrequired to connect any keyset to a PC running Windows 3.1 or Windows95. The number of CTMs that can be installed on a system is only limitedto the number of keyphones. The features and functionality of the DCS-816 keyset are not changed.

Conference

The system allows five simultaneous conferences.

l Add–On (5 PARTIES)Any combination of up to five parties (stations or outside lines) can bejoined together in an add–on conference. Parties may be eliminated oradded after a conference has been established.

l UnsupervisedA station user may set up a conference with two or more outside lines andthen exit the conference leaving the outside lines connected in anunsupervised (trunk to trunk) conference.

Data Security

Single line extensions used with modems and facsimile machines can beprogrammed so that they will not receive any system–generated tones thatwould disrupt data transmissions. In addition, these devices will receive DCS-816 C.O. ringing pattern instead of intercom ring pattern. Devices connected toan SLI port will receive a disconnect signal upon termination.

Direct Dialling Inward (DDI)

The system can use local telephone company–provided DDI service via anISDN . When programmed, anyone dialling a user's personal number will ringdirectly to that user's office. DDI calls to a busy station have the option to returnbusy signal to the C.O. or return ringback to the C.O. When ringback isselected, the called station receives off–hook ring. Multiple DDI numbers canring the same extension or station group, and display keysets show a DDIdirectory name when ringing if a name has been programmed. DDI calls that aredirected to ring a voice mail machine can be identified by a special digit.

Direct In Lines

Outside lines may be programmed to bypass the operator(s) and ring directly atany station or group of stations.

Direct Inward System Access (DISA)

Users can call in on specific DISA lines at any time, input a security code andreceive system dial tone. Users can now place internal calls or, if permitted, callsusing C.O. lines. The caller must have a tone dial phone and must know his/herDISA security code. DISA lines can be used as both–way lines or incoming onlyand may be active in day mode, night mode or both. The C.O. lines used forDISA must have disconnect supervision.

Direct Trunk Selection

Each station can be allowed access to or denied access from a trunk or trunkgroup by access code.


4 - 8

Directory Names

Each station, station group and C.O. line may be assigned a directory name(maximum 11 characters). In addition, each personal speed dial number, systemspeed dial number and entry in the DDI translation table may be assigned aname (maximum 11 characters). These names are displayed during calls withthese ports and, in the case of station and speed dial names, can be used tooriginate calls. See the Dial by Name feature (in Station Features).

DISA Security

Telephone fraud and long–distance theft continue to increase; therefore, wehave introduced a DISA security system. If an incorrect DISA passcode isentered repeatedly (as is the case with “hackers”), the DISA system can beautomatically disabled temporarily. Both the number of incorrect passcodeattempts and the time that DISA is disabled are programmable. In addition, allfailed attempts to access DISA will print on SMDR (if provided) with a "DE" DISAerror flag.

Distinctive Ringing

Users will know the type of call received by the type of ring heard. Outside callshave a single ring repeated while internal calls have a double ring repeated.

Door Lock Release (Programmable)

After answering a call from the door phone, users can dial a code to activate acontact closure. This can be used to operate a customer–provided electric doorlock release mechanism. The contact closure timer is programmable from 100 to2500 ms.

Door Phones

The door phone interface module (DPIM) provides for connection of a doorphone to a DLI port. Pressing the key on the door phone produces a distinctivering (three short rings repeated) at the assigned station or station group. If notanswered within a programmable time, the system will release the door phoneand stop the ringing. Stations may call the door phone directly and monitor thesurrounding areas.

Door Phone Night Ring

The ring destination of door phone calls may be different at night than during theday. For example, large factories may want these calls directed to a securitydesk after hours.

Executive Barge–In (Override)

The feature allows specially programmed stations with a barge–in key tooverride the automatic privacy of another station. Programming allows barge–inwith or without a warning tone. Stations may also be programmed as "secure" sothat they cannot be barged–in on.

l With Warning ToneWhen the barge–in with tone option is set, the barging–in keyset has itsmicrophone on and the barged–in on station receives an override display.


4 - 9

A double burst of warning tone sounds and repeats for every 10 seconds.This feature does not work from single line sets.

l Without Warning ToneWhen the barge–in without tone option is set, the barging–in keyset has itsmicrophone muted and the barged–in on station does not receive anoverride display. This feature does not work from single line sets.

WARNINGBARGE–IN WITHOUT TONE MAY VIOLATE THE LAW CONCERNING THERIGHT TO PRIVACY. SAMSUNG ELECTRONICS CO. LTD IS IN NO WAYRESPONSIBLE FOR THE POSSIBLE MISUSE OF THIS FEATURE.

Executive/Secretary Pooling

Each keyset may be defined as a BOSS or a SECRETARY in systemprogramming. Each BOSS can have up to four SECRETARIES and eachSECRETARY can have up to four BOSSES. These arrangements are known asexecutive/secretary pools. There can be multiple pools in a system. When aBOSS is in DND, all calls to the BOSS ring the first SECRETARY assigned tothat BOSS; if that SECRETARY is busy, the call hunt to the next availableSECRETARY assigned to that BOSS. If the SECRETARY must communicatewith the BOSS while he/she is in DND, pressing the corresponding BOSS keyon the SECRETARY's keyset results in an Auto Answer intercom call beingmade to the BOSS (provided the BOSS should be free). A station can only bethe BOSS of one SECRETARY pool. In addition, a station cannot be in morethan one pool.

External Music Interfaces

DCS-816 provides an interface for connecting a customer–provided externalmusic source. This source can be used for background music, station music onhold or trunk music on hold.

External Page Interfaces

DCS-816 provides one external page output and it can be assigned to operatewith the dry contact in the system.

Flash Key Operation

While a user is on an outside line, pressing the FLASH key will flash the centraloffice or PBX. This is used for custom calling features on C.O. lines or inconjunction with CENTREX/PBX operation. System programming allowsindividual flash times for C.O. and PBX lines. When C.O. or PBX flash is notrequired, setting the timers for two seconds releases the existing call and returnsdial tone to make a new call.

Flexible Numbering

System programming allows stations to have two-, three- or four-digit extensionnumbers beginning with the digit 2. Default extension numbers begin with 201.Station hunt group access codes can be two or three digits beginning with thedigit 5. These can be changed but will affect other feature access codes. Alluser guides are written using the default numbering plan.


4 - 10

Flexible Ringing

Each C.O. line can be programmed to ring at any station or station group. Eachline can be assigned a day ring destination and a night ring destination.

Hot Line

Stations can be programmed to call a pre–defined station or station groupwhenever that station goes off–hook. A hot line delay timer of 1–250 secondscan be programmed to allow sufficient time to make a different call.

In Group/Out of Group

Individuals assigned to a station hunt group may temporarily remove theirtelephones from the group by pressing the In/Out of Group key provided thatthere should be someone still in the group. Stations out of a group will notreceive calls to that group but will continue to receive calls to their individualextension numbers. When desired, the user may put him/herself back into thegroup by pressing the key again. Users who do not have this key may dial theaccess code and the group desired. A station user is allowed to be in severalgroups if a key and the extender of that group are assigned for each group onthe user's phone.

Incoming Call Distribution

Incoming calls can be assigned to ring a distributed station hunt group. Thisallows all members of the group to share the call load.

Incoming/Outgoing Service

Outside lines are available for incoming or outgoing service. Programmingallows any outside line to be used for incoming calls only, outgoing calls only orboth–way service.

Individual Line Control

Each station in the system can be individually programmed to allow or denydialling out as well as allow or deny answering for each outside line.

ISDN Service

For DCS-816, the DCS Compact 2BRI or 4BRI card can be installed.

l 2BRIProvides 2 BRI ports, has four channels.

l 4BRIProvides 4 BRI ports, has eight channels.

Least Cost Routing

Least Cost Routing (LCR) is the ability to automatically select the appropriatecentral office route for the outside number dialled by any station. LCR canbecome quite complicated to understand and program but does allow highlycomplex dialling decisions. The LCR package includes the following features:• Option to use or not use LCR• Programmable LCR access code• Digit analysis table: 300 entries each with 10 digits


4 - 11

• Routing by time of day and day of week• Routing according to individual station class• Modify digits table: 100 entries• Flexible trunk group advance timer• Option to use or not use trunk group advance warning tones• Clear digits when dialling

Live System Programming

The system can be programmed from any display keyset or personal computer(PC) without interrupting normal system operation. There are three levels ofprogramming: technician, customer and station. The technician level has accessto all programs and can allow the customer access to system programs asneeded. Technician and customer accesses are controlled by different securitypasscodes. Programming from a PC requires the PCMMC program.

Long Line Extensions

A single line (tip and ring) extension from the first two SLI ports may beconnected to telephone company–provided long line circuits to remote locations.

Meet Me Page and Answer

After a user makes a Meet Me Page, the user may remain off–hook to allow thepaged party to meet the user for a private conversation.

Memory Protection

In the event that power is lost to the system, all customer data contained inmemory is retained for approximately seven days. In addition, the PCMMCcomputer program may be used to produce a backup copy of the customer data.

Message Waiting Indications

When calling a station and receiving a busy signal or the no answer condition,the caller can leave an indication that a message is waiting. The message keywill flash red at the messaged keyset. A single line phone will receive adistinctive message waiting dial tone. Five message–waiting indications can beleft at any station.

Microphone On/Off per Station

The microphone can be disabled at any keyset. When a microphone is disabled,the keyset cannot use the speakerphone, although on–hook dialling and grouplistening is still possible.

Music On Hold–Flexible

Each C.O. line may be programmed to receive chimed music source, externalsources, internally–generated tones or no music when it is placed on hold. Thesystem–generated tone is a beep for every 10 seconds.

Night Service

The system provides separate ringing locations for all trunks in both the day andthe night modes.


4 - 12

l AutomaticAutomatic night service allows the system to automatically go in and out ofnight service according to the system clock. There are separate timeoptions available for each day of the week. Auto night time is operated fortrunks that have no night group (see below).

l ManualThe operator presses the NIGHT key and then dials a passcode to changeday mode to night mode operation.

l HolidayThere are 60 holiday tables. If it is a holiday, DCS-816 operates on nightmode.

Operator Group

The station groups can contain 16 stations to answer incoming calls. Calls tothis group can be set for distributed, sequential or unconditional ringing.Operators can use the In/Out of Group feature to meet flexible operatorrequirements. Default operator group is 500, but this can be changed to501~509.

Orbit Parking

Park Slots enable SLT users to park a call into a number. They can announcethe number to another user and that person can dial the Park Slot number toretrieve the call. This feature is handy for those people on SLT.

Overflow

l OperatorWhen calls ringing an operator group go unanswered, they can overflow toanother destination after a programmed period of time. The operator grouphas its own timer. The overflow destination can be a station or stationgroup.

l Station GroupWhen calls ringing a station group go unanswered, they can overflow toanother destination after a programmed period of time. Each station grouphas its own timer. The overflow destination can be a station or stationgroup.

Paging

System software allows for the use of four internal and one external pagingzones. Stations can page any individual zone, all internal zones or all zonessimultaneously. Using system programming, each station may be allowed ordenied the ability to make and/or receive page announcement to/from any zoneor combination of zones.

Power Failure Transfer (216 Base KSU Only)

If power fails and a 8TRK card is installed, these relays can be used to reroutethe pre-assigned two C.O. lines on the card to SLTs (station 15 and 16). WhichC.O. lines are to be transferred must be decided by the installer. When power isrestored to the system, the lines and stations return to normal operation andcalls in progress will be disconnected.


4 - 13

Prime Line Selection

Any station can be programmed to select a specific line, line group, telephonenumber.

Private Lines

For private line use, stations can be prevented from dialling and/or answeringany line.

Programmable Line Privacy

Each outside line can be programmed to ignore the automatic line privacy. Thisallows up to four other parties to join your conversation by simply pressing theline key.

Programmable Timers

There are over 50 programmable system timers to allow each installation to becustomised to best fit the end user's application.

Recalls

Calls put on hold, transferred or camped–on to any station will recall to theoriginating station if not answered within a programmable period of time. A recallthat goes unanswered for the duration of the attendant recall timer will recall tothe system operator group. Hold, transfer, camp–on and attendant recalls haveindividual programmable timers. Calls recalling to keys with tri–coloured LEDswill flash amber.

Remote Programming–PC

Remote programming allows the technician to access the system database froma remote location for the purpose of making changes to the customer data.Customer–provided modems, a PC using an optional software package and anSIO option card are needed to implement this feature.

Ring Over Page

Any outside line can be programmed to ring over a customer–provided pagingsystem. Outside lines, door phones and station groups may ring over page inthe day or night mode.

Single Line Connections

Single line ports allow for connection of a variety of SLTs plus facsimilemachines, answering machines, loud bells, computer modems, cordless phonesand credit card machines. When connecting customer–provided equipment tothese extensions, compatibility should be checked before purchasing to ensurecorrect operation. Central office ring cadence can be selected for SLT stations.This is helpful when optional devices cannot detect intercom ring cadence.

Speed Dial Numbers

The system has a library of 500 speed dial numbers which may be allocatedbetween the system list and stations as needed. The system list can have amaximum of 300 numbers and each station can have up to 50 numbers. Speed


4 - 14

dial numbers are assigned in blocks of 10. Each speed dial number may containup to 24 digits.

Speed Dial by Directory

The systems provide the user with the ability to look up a speed dial number andplace the call. This feature can be used with the soft keys on the display keysetsor as a programmable key.

Station Hunt Groups

System programming allows for up to 10 station hunt groups. One of threerings–sequential, distributed and unconditional–is available for each group.Each group may contain a maximum of 16 stations. A station may be assignedto more than one group. The default directory numbers to call these groups are501–509. Each station group has its own recall timer for calls transferred to thatgroup.

System Alarms

The alarm destination can be a station or station group.A DISA alarm warns the customer if the DISA security system has beentriggered by too many incorrect password attempts. The alarm can ring anystation or group of stations and show an appropriate display at the assignedstations.

System Directory

Each station, station group and outside line can have an 11–character directoryname. This name appears on keyset displays to provide additional informationabout lines and stations.

Station Message Detail Recording (SMDR) (Call Logging)

The systems provides, via an SIO option card, records of calls made, receivedand transferred. Connecting a customer–provided printer or call accountingsystem will allow collection of these records. Each call record provides thefollowing details: station number, outside line number, start date, start time,duration of call, digits dialled (maximum 18), an account code (if entered) andcall cost. (NOTE: Call cost is only available if relevant information is supplied bythe network.) The system may print a header followed by 50 call records perpage or send continuous records with no header for use with a call accountingmachine.

The SMDR format contains many options that allow it to be customised for acompany's individual needs. Options to print include incoming calls, outgoingcalls, in and out of group status, change in DND status and authorisation codes.

Toll Restriction (Call Barring)

There are 200 allow and 200 deny entries of 11 digits each. Each of theseentries can apply to dialling classes B, C, D, E, F and G. Expensive, premiumrate and operator–assisted calls, as well as specific area and office codes, canbe allowed or denied on a per–class basis. Class A stations have no diallingrestrictions and Class H stations cannot make outside calls.


4 - 15

Any outside line may be programmed to follow station toll restriction or follow thetoll restriction class assigned to it. Each station and trunk can have a day diallingclass and a night dialling class.

Toll Restriction (Call Barring) Override

Program options allow system speed dial numbers to follow or bypass a station'stoll restriction class. In addition, users may make calls from a toll restrictedstation using either the Walking Class of Service feature or the authorisationcode feature.

Tone or Pulse Dialling

Outside lines can be programmed for either tone or pulse dialling to meet localtelephone company requirements.

Transfer

System operation permits station users to transfer calls to other stations in thesystem. Transfers can be screened, unscreened or camped–on to a busystation.

Trunk Groups

Outside lines can be grouped for easy access by dialling a code or pressing akey. There are 4 trunk groups available. Access codes are 0 and 80–82.

Uniform Call Distribution (UCD/ACD)

UCD/ACD is used whenever the user expects to have more ringing calls thanpeople to answer them. It prevents callers from receiving busy signals or lengthydelays before answering. Callers reaching a busy station group are held inqueue for an available agent. First and second announcements reassure thecaller until an agent becomes free. Up to three separate UCD/ACD groups canbe created. Programmable automatic logout removes a station from the group ifa call is placed to an unattended station, thus avoiding unanswered calls. Awrap–up timer prevents calls to a station for a programmable period of time toallow the agent to finish up work associated with the call.

l Maximum of three GroupsThe UCD/ACD group option allows callers in queue at an UCD/ACD groupto be diverted temporarily to a customer–provided announcement deviceand then placed back in the queue. A wrap–up timer allows agents tocomplete paperwork before receiving the next UCD/ACD call.

l Call StatisticsThe UCD/ACD supervisor positions using a display keyset can monitor thenumber of calls in queue, the time that the oldest call has been waiting, thetotal number of calls received for the current day and the average time acall waits to be answered.

l Agent StatisticsUCD/ACD supervisor positions using a display keyset can monitor thenumber of agents in a group and how many agents are currently logged in.Each station's status can be reviewed for the number of calls answered andthe average call length of the current day.

Universal Answer

Station users may dial the Universal Answer code or press the UA key to answerany outside lines programmed to ring the UA device. The UA device can be astation, group of stations, common bell or ring over page.

Voice Mail Integration

The system uses DTMF tones (inband signalling) to communicate with a third–party-supplied compatible voice mail system. Stations can call forward to a voicemail system. When answered, the system sends DTMF tones, routing the callerdirectly to the called station user's mailbox. Keyset users can press one key toretrieve messages from the voice mail system.

VPN The VPN (Virtual Private Network) feature allows the DCS-816 to operate in aclosed numbering group based on a 5 or 6 digit dialling plan for all members ofthe closed numbering group. In this case the local site DCS-816 extensions alsooperate with a same 5 or 6 digit extension number. The feature uses the LCRtables to identify and route calls within the closed numbering group and normalexternal calls. Local site calls are identified based on a programmable 2- digitself-identification code. The system, when the feature is set to ON in MMC 210, automatically entersLCR mode and analyses the digits dialled. If the first two digits are the same asthe system Self ID code programmed in MMC 724 the system will activate thefeature based on the following digits dialled, e.g. internal call. All other outgoing

calls are routed in accordance with LCR related tables MMC 710, MMC 712 andMMC 713.

Walking Class of Service (WCOS)

This feature allows users to make calls or use features from a station that isrestricted. The users may either use the WCOS feature code or theauthorisation code feature. Both methods change the class of servicecorresponding to the station passcode or authorisation code that is dialled. Afterthe call is completed, this station returns to its programmed class of service.

4.4 STATION FEATURE DESCRIPTIONS

Appointment Reminder

Keysets with an alarm key can be used like an alarm clock. When programmedfor a specific time, the keyset will sound a distinctive ring to remind you ofmeetings or appointments. Alarms can be set for "today only" or for every day atthe same time. Up to two alarms may be set at each keyset. Display keysets canalso show a programmed message when the alarm rings.

Automatic Hold

Station users can enable or disable automatic hold at their keysets. While a useris engaged on an outside (C.O.) call, pressing another trunk key, route key orCALL key automatically puts the call on hold when this feature is enabled.Pressing TRSF, CONFERENCE, PAGE or a DSS key will always automaticallyplace the call on hold. This type of automatic hold is not a user–selectableoption.

Automatic Privacy

All conversations on outside lines and intercom calls are automatically private.The privacy feature can be turned off on a per–line basis.

Background Music

When a customer–provided music source is connected, each keyset user maylisten to background music. The HOLD key turns background music on or off andthe volume is controlled by the volume control keys. One music source can beexternally connected to the system. Chime music is available by default.


4 - 19

Busy Station Callback

When reaching a busy station, callers may request a callback by pressing onekey or dialling a code. The system rings the caller back when that stationbecomes idle (a system–wide maximum of 100 callbacks are allowed at one time,including busy station and busy trunk).

Busy Station Indications (BLF)

DSS/BLF keys may be assigned to any keyset. These keys will be off when thestation is idle, light red when that station is in use and flash distinctively when thatstation is in DND mode.

Call Forwarding

Station users can forward internal and outside calls to other destinationsimmediately (Forward All), when busy (Forward Busy) or when not answeredwithin programmable duration (Forward No Answer).

These forward destinations can all be different. Once a destination has beenprogrammed, it can be turned on and off with a programmable key. Forward AllCalls takes priority over Busy and No Answer conditions.

In addition to the three usual methods of forwarding described above, a fourthoption called Follow Me is available. This option allows station users to set aForward All condition from his/her station to another station while at the remotestation. To display the Follow Me condition, the TRSF key lights steady red at thestation that is forwarded. The TRSF key also lights if Forward All is set and nokey is programmed for Forward All.

Keyset users can also be given an external call forward key to forward their callsto an external phone number. Each outside line may be programmed to eitherfollow or ignore station call forwarding. A per–station option controls whetherinternal calls forward to voice mail or not. SLTs must have the systemadministrator program this feature for them.

Call Pickup

With directed call pickup, a user can answer calls ringing at any station by diallinga code plus that extension number. The group pickup feature allows the user toanswer any call ringing within a pickup group. Pickup keys may be customisedwith extenders to allow pickup from a specific station or pickup group. The DCS-816 has 8 programmable pickup groups.

Dial By Name

Each system and personal speed dial number can have an associated directoryname. A speed dial number can be selected by scrolling alphabetically throughthe directory name list. This on–line “directory” allows the user to look up and dialnumbers in seconds.

Direct Station Selection (DSS)Programmable keys can be assigned as DSS keys and associated with extensionnumbers. Users press these keys to call or transfer calls to the assigned stations.


4 - 20

DND Override

The Do Not Disturb (DND) feature is used to stop all calls to a station. However,an extension that has a class of service that allows DND override can overridethe DND status of another extension using the DNDOVRD soft key or DNDOVERIDE ID.

Do Not Disturb (Programmable)

The Do Not Disturb (DND) feature is used to stop all calls to a station. Systemprogramming can allow or deny use of the DND feature for each station. Partiescalling a station in DND will receive reorder tone. A keyset without a DND key canactivate DND via the feature access code. The ANS/RLS key will flash at 112 ipm(rapidly) when DND is set. There is a programmable option to allow a C.O. line tooverride DND at its ring destination if that destination is a single station.

Door Lock Release
