You're welcome. Today, C-bit is typically used when you have a point 
to point circuit. M23 is typically used when you have a channelized 
DS3. Check with your carrier to make sure you are using the same 
setting. Basically, with M23, you can use the extra signaling slots 
which would have been used by CBit to recover from clock slips to 
carry signaling info. Here is a white paper with more than you ever 
wanted to know.
