- Technical Specifications

Valiant Communications introduces its G.703, 64Kbps Sub-Rate Multiplexer.

G.703 Subrate Multiplexer Valiant's G.703, Sub-Rate Multiplexer multiplexes six 9.6Kbps RS232 asynchronous data channels to a 64Kbps, G.703 co-directional, 4 wire synchronous data channel.

The front panel has six, RS232 data ports into which upto six, RS232 asynchronous data channels @ 9.6Kbps each may be connected. The six RS232 asynchronous data channels @ 9.6Kbps are multiplexed into a 64Kbps, G.703 co-directional, 4 wire synchronous data channel, which is accessed from the system backpanel (rear).

External Interfaces And Connectors :

VCL G.703 Sub-Rrate Multiplexer provides the following interfaces to the external world:

-48V input for on-board power supply
2 External alarm extensions for visual and audible alarms.
6x RS 232, 9.6Kbps asynchronous data interface(s)
1x64Kbps, G.703, Co-directional synchronous data interface
