DCN-16U digital subscribers exchange unit is designed for operation as a part of DCN digital Intercom and PA/GA system on the basis of DCN-2 or DCN-Q4E switching processor module and provides for interfacing with digital subscriber equipment by Uk0-interface. DCN-16U transmits digital data between 15 subscriber Uk0-interfaces and E1 line of a central exchange unit. In addition, there is a version of DCN-16U with built-in DCN-Q4E switching processor module.
DCN-16U allows connection of desktop and wall-mounted digital intercom stations, at a distance of up to 6 kms.
DCN-system has improved high speech bandwidth – 6.8 kHz. It has improved speech clarity and makes it possible to use equipment in noisy areas.

Connection of up to 15 digital subscriber devices to DCN system by the digital two wire subscriber interfaces Uk at a distance of max. 6 km;
Local control and diagnostics using two-colour LED indication on the front panel of subscriber interface and E1 line status;
Creation of low capacity DCN system (up to 15 digital subscribers, expandable up to 60 subscribers when connecting additional DCN-16U), for a version with DCN-Q4E module;
“Phantom” power supply of subscriber units by Uk0-interface line;
DIN41612С socket for connection of digital subscribers, a group of phantom power fuses, strip of jumpers for power supply to subscriber units;
DRB-25FA socket for 4 E1 lines connection cable of DCN-Q4E module, if installed, on the back panel;
The connection cable is equipped with screw terminals for connecting lines of subscriber Uk0-interfaces that are located on a DIN-rack mountable board. There are failure signal relays on the cable board.
