asterisk users - Apr 2009 - Alcatel OmniPCX Enterprise + Asterisk with E1

Hi all,

I'm new in the forum, and although I have some experience in Asterisk,
I've
never work with Asterisk FXO, FXS, E1... cards.

I have several costumers with ATAs working with my SER. However one of them
bought an Alcatel PBX OmniPCX Enterprise and now he wants I give him a E1
interface for interconection with its new PBX.

I understand I need a E1-IP gateway which could be Asterisk I think. So the
network would look like this:

Extensions-----OmniPCX---E1---Asterisk--------IP--------------SER

About that, I have a few question:

1. Anybody has done this interconection? How does Asterisk and PBX OmniPCX
work together through an E1 interface? Any problems or bugs?

2. What E1 card should I buy for Asterisk? Is the physical interface
(conectors) E1 identical as T1?

3. If cost wasn't a problem, do you suggest another interconection way
technically better? May be replacing Asterisk with another device with an
in-box E1?

Thanks very much in advance,

Sebastian

The connectors are identical, however the protocol isn't.  However, just
about all the T1 cards I'm aware of support E1 as well - usually
selected by a jumper on the card.

Theoretically the Alcatel OmniPCX could be trunked to Asterisk via SIP. 
Sometime very soon, I'll be trying to integrate ~40 OmniPCX systems via
SIP, but haven't begun work on it yet.

I haven't worked with the omnipbx's but i have with an alcatel 4400 and
used
a sangoma A108 and A104.. the sangoma cards work perfectly and if you have
nay issues sangoma support are always more than happy to help - and they
actually know what there talking about as apposed to having someone reading
a script.

as for different devices, you could use one of those vegastream devices,
i've got a vega 400 but have never used it and so can't comment on how
good
/ bad they are... but the vega 400 allows up to 4 (i think) e1/t1
connections converted to SIP.

Hi Sebastian,

Sebastian Milioto a ?crit :
| 1. Anybody has done this interconection? How does Asterisk and PBX
| OmniPCX  work together through an E1 interface? Any problems or bugs?

I have two similar installations (OmniPCX<-E1->Asterisk); they have been
running, one of them since early 2005, passing more than 700 000 calls.

|
| 2. What E1 card should I buy for Asterisk? Is the physical interface
| (conectors) E1 identical as T1?

Digium TE110P or newer.

|
| 3. If cost wasn't a problem, do you suggest another interconection way
| technically better? May be replacing Asterisk with another device with
| an in-box E1?

I now prefer to put asterisk between the telco and the PBX, using a dual
E1 card.


Thanks,
