[Asterisk-Users] use of Asterisk and T100P as Nortel DSX-1?

[Jim Ockers]

Hi all,

I've seen a couple of posts recently from people who are doing
something with Asterisk and a T100P and a Nortel PBX.  However it's
not clear exactly what they are doing.

Does anyone know if it's possible to use a T100P or T400P as a DSX-1
interface to connect to a T1/PRI CO module in a Nortel PBX?  We have
a Nortel Norstar Modular ICS PBX and I'd like to plug its CO module
into an Asterisk server, for interesting reasons.

Nortel's ATA/ASM for analog stations are not suitable for use with a 
softswitch like Asterisk and FXO interfaces.  Also, Nortel has no T1 
station module, so I think I could only connect Asterisk to a CO card.  
In this case, the Asterisk server needs to act like a telco for the 
purposes of the Norstar.

Will this work?

Also, I'd need to set DID digits on calls delivered to the Norstar
so that I could control the call routing.  All of the posts I've seen
to this list indicate that Asterisk can decode DID digits, caller ID,
etc. that are delivered to it, but I haven't seen any indication that
Asterisk can SET the DID information on a call being delivered to another
PBX.

Will this work?

I already know how to use coordinated call routing to deliver calls
from the Norstart to Asterisk.

These ideas would be a really handy use of Asterisk.  If this stuff won't 
work, what might it take to make it work?  I suspect it's more complicated 
than just using some sort of crossover cable and connecting them together.

Thanks to the list denizens I've learned how to make Asterisk interface
very nicely with a dumb pbx using the Flash and SendDTMF functions, but
I would love to know the best way to make ASterisk interface with a
smart PBX.

Thanks a lot,
Jim
