V.35/V.54 Loop
V.35/V.54 Service Card Description
The V.35 Card with V.54 Loop Test provides the capability for the V.35 card to detect
network loop back initiation signals and provide a network loop back for loop testing.
Each channel of the V.35 will continuously monitor the incoming data bit stream for a
particular loop pattern. On detection of the pattern the channel will acknowledge the
loop test request and put the channel into loop back. The channel will then continuously
monitor for the loop test end pattern. On detection of the loop end pattern the channel
will remove loop back and resume normal operation. Front panel LED’s will indicate
Loop test. Each channel can also initiate the loop test pattern causing another V.54
compatible device to loop back. The channel will then transmit a test pattern and
calculate bit error rate (BER).
