Meridian Option 11C

Difference Between 11,11E,11C

Option 11 2 CPU Cards: CPU/CONF (Conference Loop) and TDS/DTR (Tone Digit

Switch/Digit Tone Rxer) – occupied 2 slots. 1 Expansion cabinet 224 Ports(including Trunk & Digital cards) Connectivity of expansion cabinet to main cabinet: Copper Connectivity only Max distance bet main & expansion is 2.12 m. Max 10 slots for cards excluding power supply. Operates on AC. Connection from 1st slot of expansion cabinet to anywhere between 2 & 9 of

main cabinet.

Option 11E System core ( contains cartridge containing customer data base) 384 ports 2 expansion cabinets Copper or fiber connectivity for the expansion cabinets to the main.

Max distance between 10 m. Fiber Connectivity : MFI Card(Main Fiber Interface) & EFI Card(Expansion

Fiber Interface) Rls 22 & 23.

Option 11C SSC (Small System Card) Motorola 68040(CPU/16 MB of DRAM) S/W Daughterboard Two slots for fiber expansion Max of 4 expansion cabinets 700 ports Rls 24 & 25 If connecting a single expansion cabinet – require a single daughterboard If connecting a 2 expansion cabinet – require a dual daughterboard If connecting a 3 expansion cabinet – require a single & dual daughterboard Max distance between main & expansion can be 3 Km.

General Details EPABX – TDM Switch Total 10 Slots Slot 10 – Meridian Mail (MM) SSC contains Dongle & S/W Daughterboard Dongle – Lithium Battery storage – Contains Site ID (System) & Auxiliary ID

(Up gradation) Rls 23 & 24 – 32 MB S/W Daughterboard Rls 24.24 & 25 onwards – 48 MB S/W Daughterboard During up gradation we need to change the S/W Daughterboard which

upgrades the Flash part of the Memory. NTTK13AA & NTTK25AA – 48 MB S/W Daughterboard available at Market. SSC Card: Occupies one slot – can insert PCMCIA Card A: & B: drive - A: Up

Digital Line Card

16 ports each port as a TN(Terminal Number) Loop Shelf Card Unit (l s c u) DN – Directory Number (extn No)

SSC Card 3 Serial ports

Port 0, 1 ,2 - Maintenance (To view ACD,CDR & Login Purpose) Ethernet Connectivity – assign a IP (PC) CDR (Call Detail reporting) – Log of outgoing & incoming calls ACD (Automatic Call Distribution) – automatically distributes the call

depending on the most idle agent – suitable for call center – need to capture the reports.

Need to configure a D-Channel EURO, Q Sig, ESS4, SL1 – Protocols Between switches by which data can be

sent thru D Channel Outband Signaling – Signaling has a separate channel (CCS- Common Channel

Signaling) All signals are passed via D-Channel The line remains idle as long as acknowledgement is not rxed although the call

is placed

MITG (Meridian Integrated (IP) Telephony Gateway) Voice over IP – Extending ur voice in network over Internet

Two Types : (1) Line side (using IP Phone over WAN) (2) Trunk side (Connect two meridian over Ethernet) ITG – TDM to convert IP Packets & Compresses data ITG 1.0 – Works with Rls X.11 onwards ITG 1.0 – 8 simultaneous calls – occupies 2 slots ITG 2.0 – 24 simultaneous calls – occupies 2 slots – OTM 2.0 or later ITG 3.0 – 32 simultaneous calls – occupies 1 slot – OTM(Optivity Telephony

Management) 2.0 or later – MC (Media Conversion) Card MAT (Meridian Administration Tools) 6.1 or later – PC with Windows 95 or

later

Has 2 Ethernet ports, one is for E LAN & one is for T LAN Connection MAT is connected to E LAN of Meridian & E LAN of MITG Dongle ID is there for ITG 1.0 but ITG 2.0 & 3.0 does not require Dongle

ID. Supports CDR (Call Detail reporting) & SNMP Alarm Traps

Prerequisites For Configuring ITG Stable & dedicated IP Address for ITG Card Node IP address (T LAN IP address on the ITG) Management LAN Gateway IP address Management subnet mask Voice LAN gateway IP Voice subnet mask Keycode of MITG Card Dongle ID of MITG Card MAC Address of MITG Card

Line Card No ITG 1.0 Version Does not require a Meridian on the other end. It requires only a IP Phone. 24 ports per card (ITG 2.0) & 32 ports per card (ITG 3.0) Supports up to 96 Internet Telephones per card (Virtual Connection within LAN)

Trunk Side Connects two Meridian over Intranet & ordinary phones are enough for communication.

Hardware Installation Insert MITG Card in any IPE Slot Connect the cable corresponding I/O Slot & other E LAN for MAT/OTM ,T LAN for Customer

MITG Card 8/24/32 port trunk card Two Ethernet ports & one serial port (Card Management) Acquires 2 physical slots (ITG 3.0: 1 Slot) It has Dongle (only for ITG 1.0), RAM, Flash ROM, Processor G.711 (64 Kbps), G.729 (8 Kbps), G.729AB (8 Kbps) – Codec supported (for

Compression Standards) Protocol used: TCP/IP IP to IP Phone: Virtual Port is used IP to Analog/Digital: Physical port is used
