Channelized T1 uses robbed bit signaling Instead of 1 data and 23 bearer
channels it has 24 channels but each one only carries 56k because 8k is used
for signaling.  The portmaster 3 does it using DOV without doing anything
special.  I was hoping there was a way to get the 6096 to do the same thing,
but it looks like I'm going to have to change the CT1 circuits to PRI
