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.
