Orion's VCL-30, 2Mbps E1 Channel Bank
multiplexers support Cisco, Nuera, 3Com, Lucent VoIP servers that are used for terminating
long distance traffic with PSTN lines that SHALL SUPPORT, or, DO NOT SUPPORT "battery
reversal / polarity reversal" (answer supervision).

NEW Channel Bank from Orion

The VCL-30, E1 channel banks are available in two versions:
- VCL-30 can be used with PSTN lines that SHALL SUPPORT
"battery reversal / polarity reversal" (answer supervision).
- VCL-30 "spoofs" battery reversal / polarity reversal
(answer supervision), and can be used with PSTN lines even if they SHALL NOT SUPPORT
"battery reversal / polarity reversal" (answer supervision).
- The first version of the VCL channel bank version is one which
expects a "battery reversal / polarity reversal" condition on the analog line
when the call is ANSWERED by the CALLED PARTY. The VCL channel bank
shall feed the call answered bits to the E1 side so that the billing server may commence
its billing. This happens as soon as the call is ANSWERED by the CALLED PARTY and the PSTN
initiates a "battery reversal / polarity reversal" on the analog line.
- However, if the PSTN lines are NOT SUPPORTING "battery
reversal / polarity reversal" the VCL channel bank shall automatically, based on the
statistical analysis of a circuit usage, extend the call answered bits to the E1 side, so
that the billing server may log the call and commence billing. This is particularly useful
in an environment where the PSTN analog lines DO NOT SUPPORT "battery reversal /
polarity reversal", which would be otherwise required for commencing the call
metering / billing.
