[Asterisk-Users] non-telephony use of T400P?

[Don Pobanz]

Another issue to consider is T1 framing. If your application is putting 
bits onto the T1 at the rate of 1.544 Mbit/s then the T1 would need to 
be unframed. I don't believe this is an option in zaptel! If however, 
it is putting bits on at a rate of 1.536 Mbit/s and adding 8000 bit/s 
for framing then you may be able use the suggestion below.
