DAMUX - PDH Multiplexers
DAMUX is a PDH multiplexer that combines over a framed E1 to the network data coming from up to 5 ports: 1 G.703 Drop & Insert port for PABX connection, 2 serial (nx64) synchronous ports synchronous for router or videoconference systems connection, 1 bridge 10BaseT for LAN or PC connection and 1 RS-232 asynchronous port for low speed access control systems. The 2 serial ports can be software configurable between different electrical interfaces as RS-232(V.28), RS-422(X.21), RS-449(V.11), V.35, V.36.
The multiplexer can be managed locally using the GUI DAVANView Lite software over Windows OS by means of a serial RS-232 asynchronous port that can also be used as a console port for system configuration with an HyperTerminal or any other VT100 emulation. The multiplexer can also be equipped with an optional SNMP Agent for remote management with DAVANView SNMP Manager software.
The multiplexer has a standard 19’’ rack mount format 1U height. Power supply can be AC or –48DC.
