[Asterisk-Users] What do I need to ask my T1 supplier?

[Damon Estep]

I know we have sold XO integrated access voice /data to customers that
used PRI interfaces on their PBX, so you should be able to order the
voice provisioned as follows;

ISDN/PRI
NI-2 (national ISDN 2)Format (ATT 5ESS Will also work)
Transmit at least 4 numbers on DID
Order a block of DID numbers on the circuit large enough to assign one
to every extension plus some extras for future (request a contiguous
block of numbers)
B8ZS coding
ESF Framing

Their channel bank should hand off Ethernet for data and PRI for voice,
not POTS.

Interface with * using a single span T1 Digium card (T100P?). You will
need to replace FXO interfaces you have them.

The digital signaling and DID are features you want to have.

My employer is switching to a new T1 supplier (it was AT&T, we are now
going with XO), and sometime in the future we want to replace our PBX
with an Asterisk system.

What do I need to know to make sure the T1 line is "provisioned" (is
that the right term?) correctly for a Digium T100P/TE410P/TE405P?

They will split the T1 line into 10 channels of voice and 14 channels of
data.  
>From what I understand, they will terminate the T1 into a channel bank,
and then from that give is 10 POTS phone jacks and one data port (to go
to an Adtran router for our Internet access).

Any comments and/or suggestions?

Scott
