asterisk users - Dec 2004 - Asterisk with T1

Hi,
    We are moving to a new building late in January and I have been tasked with
the job of setting up the phone system. I have ordered a full T-1 for voice and
am considering using Asterisk as the PBX. I have a Dell PowerEdge 2650 that I
can use for Asterisk. I have also looked at some T1 cards from Digium to go
with this but I am not sure which one to pick. Can somebody provide me with
quick answers/pointers regarding the type of T1 card I should buy, signalling,
framing etc, configuring the DIDs on Asterisk etc that I should give to my
provider and any other stuff that I should be looking at. The provider wants
details quickly and being the holiday season I can't seem to get quick
answers.
Any pointers would be greatly appreciated.

Thanks

Ravi Ramamirtham

For a single T-1, you want either a T100P or a TE110P, whichever Digium 
is shipping now. You want your T-1 configured as an ISDN PRI using NI-2 
signaling, with the T-1 loop in ESF framing and B8ZS line coding.

As far as configuring the DIDs in Asterisk, you will need to learn the 
Asterisk dialplan system (extensions.conf). The wiki contains lots of 
information about that, so you should start there and come back here 
when you can ask more specific questions :-)

Well, according to Digium, they don't support T1 data mode on their cards.
The reason for this stems from the fact that you have to do a kernel
recompile to add in HDLC support; it is not present in standard RH/FC
install.

says his companies cards work perfectly with asterisk and apparently don't
need a kernel recompile. He also said he would provide full support for any
configuration.

I'm currently using a T100P in PRI mode and it works great. I'm going to
do
a kernel recompile tonight and see if I can get T1 data mode to work. I've
recieved instructions from Digium via email on how to do it. If all
successful then I'll post on the Wiki.
