[Asterisk-Users] Channel Bank configuration

[Marty Mastera]

Hello,

I don't have any experience with channel banks and would appreciate any
feedback on my theory outlined below:

We have a single T1 entering the building with channels 1-12 being voice
lines and 13-24 being a 768k internet connection.  This T1 terminates to
an Adit 600 (T1-1). 

Here's what I know.  Channels 11-12 go out the Adit 600's 25-pair
connector to a wiring block (and eventually to 2 fax machines - I assume
this is to have the fax machines bypass the currently installed phone
switch).  The data comes out the Router card on the Adit and into our network.

The currently installed phone system is an NEC NEAX2000 IVS box which is
connected by CAT5 to the Adit 600's T1-2 port.  (I am assuming that voice 
channels 1-10 are mapped to the Adit T1-2 and getting to the NEC this
way....There is also a 25 pair cable leaving the NEC and terminating on a 
wiring block for the desk phones.

So my assumption is that channels 1-10 are mapped as FXO onto the Adit's
2nd T1 port, channels 11-12 to the Adit's 25-pair connector and 13-24 to
the router card for data.

This leaves the NEC box to handle the FXS (and hence why it is directly
connected to the phones).

When I replace the NEC box with an * box/T100P, I'm thinking that I will
have to map Channels 1-12 to the T1-2 port and map the 8 Adit FXS
channels on the T1-2 port to the Adit's 25-pair for the Adit's FXS
capability....then run that T1 into the T100P and configure * to route
between the FXO and FXS channels appropriately.

Does this sound right?  I'm trying to understand if the channel bank uses 
the T1 from the Adit for both FXO and FXS channels!

Thanks,

Marty
