I believe this looks like a standard channel bank.  Asterisk generates all
audio.  Ring and hook status are sent out of band.  Dial tones are in-band.
Ringback, busy, congestion are in-band audio.  I would think a standard T1
card would be fine.

That said, I would verify this with the LEC.

Does anyone know if AT&T EELs delivered to a CLEC would be PRI, or Robbed
bit?
