Connect Asterisk to Alcatel OmniPCX 4400 via E1 and TE410P

[lenina]

Hi there,

I've tried to follow http://www.voip-info.org/wiki/view/Alcatel+4400+via+PRI / viewtopic.php?f=227&t=840 but for some reason, things do not work for me - more specific: I can't get layer2 to work on the E1 and therefore can't get calls on the E1 to work in either direction. This is my current setup:

OS: Ubuntu 14.04.3 LTS
Linux asterisk 3.19.0-49-generic #55~14.04.1-Ubuntu SMP Fri Jan 22 11:24:31 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

I'm using the following software, compiled from source:

• asterisk-certified-13.1-cert3
• dahdi-linux-complete-2.10.2+2.10.2
• libpri-1.4.15
• pjproject-2.4.5

The card is recognised as follows:

As far as I can tell, things look not bad in asterisk either:

Incoming calls don't even generate output on the console. I've got a PRI tester (Acterna) which I've used to check the cabling: from the tester to the Alcatel, the line is green completely (L1 and L2) and I can place calls. Plugging the Acterna to the TE410P yields a green L1 signal, but the L2 LED stays red - so there's something fishy in my configuration, only that I currently can't tell what.

Any ideas?

I've also tried the latest dahdi-Version (2.11.0) which yielded a quite instable setup. Also I've tried the ubuntu asterisk packages and I gave the freepbx a try in order to mitigate some probable asterisk-dahdi-libpri mess.

Right now, I'm out of ideas what else to test. Are there any ideas how to debug things e.g. from the Alcatel side? Am I missing something?

really sure that layer 1 is ok?

there is an entry in asterisk forum -> http://forums.asterisk.org/viewtopic.php?f=14&t=87570

the output from asterisk console looks like yours.
at the end it was a cabeling problem.

for further investigation please attach the configuration of oxe-trunkgroup and the state of the led's (in frontpanel of the oxe-pra board).

To connect 2 system through ISDN PRI, there are 2 ways, ISDN with QSIG or master Slave, Network and user mode.

QSIG mode

Both system should support QSIG protocol, it mean master and slave is defined on based of communication sequences.

Master Slave-network and user

For these mode one system should be network or master, and the other should be set as salve or user side.

For set Master on asterisk you should change on dahdi-channels.conf signalling mode

signalling = pri_cpe <--- cpe mean "user or salve mode"
signalling = pri_net <--- net mean "master or network side"

Take care to set the proper timing sources in DAHDI, Usually the NET always provide timing, these only could causes bearer troubles.

Good luck
