Call 301-924-7400 ext. 17 for Information and Pricing

The Coastcom R344 Series is an access DACS-Mux that combines numerous digital access interfaces into multiple E1 or T1 lines for convenient traffic transport and switching. It acts as a full cross-connect MUX or mini-DACS.  The R344 management is accomplished through a VT100 console port, as well as Ethernet, SLIP, Telnet, or SNMP, for easy monitoring and control from local or remote locations. Choose in-band or out-of-band management. Fault detection and analysis is made easier using status LEDs, loopback diagnostics, and built-in BERT test patterns. Network Management is also available for alarm monitoring, control, and configuration. The shelf uses 1 or 2 DC (-48V) load sharing power supplies and either 1 or 2 hot pluggable, redundant controller cards. Requires a single or redundant external AC-DC power supply.

Interfaces include Quad E1/T1, HDSL, U type used in ISDN, RS232, E&M, 2- and 4-wire voice, V.35 and Ethernet.
The built-in DACS function allows T1 or E1 lines to be groomed for optimal channel utilization
