G.703 Sub-Rate Multiplexer
- Technical Specifications |
Description Valiant Communications introduces its G.703, 64Kbps Sub-Rate 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).
