1 DESCRIPTION AND OPERATION

1.1 Product description and operation

1.1.1 Functions

DCN-16U is designed to operate as a part of DCN-2 or DCN-Q4E-based DCN communication system as a module of digital subscriber sets to connect the subscriber devices via Uk0-interface. DCN-16U transmits voice traffic channels and signaling among 15 subscriber Uk0-interfaces and E1 line to a central exchange unit, and it doesn’t function as an exchange for connections between subscribers. Armtel DCN communication systems built-up using these products provides for voice communication between loud-speaking subscriber units made by Armtel LLC, VoIP subscribers, public address and general alarm.

Base version of DCN-16U has advanced features in version with preinstalled DCN-Q4E switching processor module.

DCN-16U Exchange of ARMT.665200.001-01 version has pre-installed switching processor module DCN-Q4E (4хЕ1) ARMT.665200.010, which is a small central exchange unit of DCN system and provides for switching voice channels up to four E1 lines enabling to connect a subscriber switching unit for 15 digital or analogue interfaces to each of them. Therefore, maximum capacity of DCN-Q4E-based system can be up to 60 subscribers.

The switching processor module DCN-Q4E intended for use as central exchange unit of DCN system, at the enterprise of industry and transport. DCN system (Armtel LLC) built with product provide simplex communication between loud-speaking subscriber devices manufactured by Armtel LLC, duplex communication with telephony subscribers, paging, and emergency loud warning.

DCN-16U is installed in control or office rooms.

DCN-16U Exchange both versions are shown in Figure 1.

b) version ARMT.665200.001-01 (with pre-installed switching processor module DCN-Q4E)

Figure 1 – DCN-16U Exchange

In DCN-16U Exchange with DCN-Q4E switching processor module DCN-16U Exchange can be directly connected to a built-in processor module DCN-Q4E. This version of the product may function as central exchange of DCN system, enabling connection up to 15 digital subscriber units and three E1 lines to it to communicate with DCN system exchange units or other equipment.

Digital communication system DCN has flexible distributed structure, where single stations are linked into a single network by E1 digital lines. DCN communication system station (or central exchange) consists of DCN-2 or DCN-Q4E central exchange with DCN-16U and DCN-15A exchange equipped with digital and analogue subscriber interfaces connected to it by E1 lines. E1 lines can also be used as ISDN PRI lines to communicate with external telecommunication systems or to connect multichannel communication recorders. DCN IP-gateway providing communication with different IP-devices can also be used as DCN system station.

Each DCN-16U exchange is a subscriber lines equipment module with 16 Uk0-interfaces for connecting digital subscriber devices, and an E1 interface for connecting to a DCN central exchange (16th interface is not used). Digital subscriber interfaces enable to connect both Armtel equipment (DIS, DW, А8, DWEx, DTS5, Analogue subsystem module), and third-party equipment with Uk0-interface (ISDN telephones, ISDN adapters for analogue telephone connection, DECT stations with ISDN interfaces etc.). In order to improve intercom system quality when operating Armtel subscriber units, an expanded sound transmit frequency band of 6.8 kHz is used. DCN-16U is connected to a central exchange of DCN system by E1 line, which is used for transmitting voice traffic channels and signaling between the central exchange and subscriber units. Therefore, all functions of communication and control of subscriber units are implemented in the central exchange of DCN system and DCN-16U subscriber exchange performs no functions if not connected there to.
