Slide 1
VCL-SR-MUX
Product Overview
Valiant 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).
• The equipment uses data buffering and phase-lock-loop techniques to ensure error free
multiplexing and demultiplexing between the synchronous and asynchronous data ports.
• Front panel LED indicators indicate presence of Transmit and Receive data signal on
each of the data ports.
The equipment operates on a nominal -48VDC Input (-40VDC to 60VDC Input). The
system also provides two dry-contact relay alarm outputs (normally open) on the backpanel
(rear) which close to indicate the presence of a system alarm.
