asterisk users - Jul 2003 - T1 config for robbed-bit E&M AMI

I have a couple of live T1s sitting around and they are not ISDN(like most
of the people that are using Asterisk seem to be using), they are regular
old 24 channel, robbed-bit, E&M wink start, D4AMI T1 circuits.  
Can I get these T1s to work with a T100P Digium card and asterisk? 

Searching through the lists and the documentation I haven't seen any
examples of how to configure this kind of T1.

 Is anyone currently using these kind of T1s on their Asterisk system?

Any help would be appreciated.

Thanks,

MATT---

T100P handles the E&M wink start signalling as well as D4AMI
framing/coding.

The config in /etc/zaptel.conf

span=1,0,0,d4,ami
e&m=1-24

in /etc/zapata.conf
[channels]
signalling=em_w
context=incoming
group = 1
channel => 1-24

But read more and have all the keywords/options that you need added to
config files.

regards
Martin

I have not done so but asterisk should handle this. See zaptel.conf 
file for configuration notes.

for a T400p card, configure zaptel.conf
for 1st span
  span=1,1,0,d4,ami
for 2nd span
  span=1,2,0,d4,ami

assuming
you want to get your clock from the first T1 if available or 2nd T1 is 
1st is not available.
the T1 is terminated close to your asterisk system (less than 133 feet) 
framing is d4 (SuperFrame or sf)
line coding is ami

also in zaptel.conf
  e&m=1-48

in zapata.conf you would set the wink information
  signalling=em_w
see zapata.conf notes in file for more information

Whether on T100P or T400P it should work the same. Also the D4 AMI is
just implementation details, not important to the functioning of the E&m
wink. I used to have E&M wink on my MCI line, but we have since moved to
PRI. E&M works fine, but one thing that some of our customers like is
that it takes less time to connect when it is PRI than E&M wink.
