Cabling Voice
Server/DSP
Functions The Vanguard 7300 Series Voice Server/DSP PMC has no connectors. Voice
functions are provided by Ports 1 and 2 on the T1/E1/PRI rear transition module.
These two ports support the voice PMC with channelized T1, E1, and ISDN/PRI.
With the voice PMC installed, a software-configured voice interface can handle only
channelized PMC voice signals or data, but not both voice and data. Each voice port
requires a 15-ft. T1/E1/PRI cable.
