Repeat Steps 6–10 for channel B.
13.5.1 E & M Signaling Test
The signaling information is sent transparently
along with the voice information on the same DS0
channel. On the P2 Signaling terminal block on
the V4W rear interface do the following:
Jumper B to M on one end for channel A, then
on channel B. This jumper may already be
installed at the factory depending on your
configuration requirements.
The E LED on the appropriate channel should
also light. A contact closure should be
detected between E & G for the appropriate
channel.
Once you have completed testing each channel,
remember either to turn off any loop backs you
executed with FCS or to disconnect any cable
loop backs.
