[Asterisk-Users] TE110P on E1

[Koen Van Impe]

Hi,

I wonder if anyone is using Digium's TE110P card on an E1 connection.
I have been try to, but so far it wasn't much of a success.
It only works more or less in EuroISDN as PRI CPE.
And even that config gives me some trouble with channel negotiation.

My current config:
*zaptel.conf:*
span=1,1,0,ccs,hdb3
bchan=1-15,17-31
dchan=16
loadzone=be
defaultzone=be

*zapata.conf:*
[trunkgroups]
trunkgroup => 1,16
spanmap => 1,1,1

[channels]
context=incoming-pri
switchtype=euroisdn
pridialplan=national
prilocaldialplan=national
signalling=pri_cpe
group=1
channels => 1-15,17-31

I have tried EuroISDN and QSIG in both NET and CPE, without much success.
>From traces of D-channel messaging, I think there's a problem with channel
negotiation.
The information element (IE) involved only shows 5 bytes coming from our
PBX.
But Asterisk (Zaptel) uses 6 bytes. From pri debug messages on Asterisk, I
see that it adds a "DS1 Identifier".
I haven't seen that in other d-channel traces between other systems.

Anyone with experience on this matter???

Regards,

Koen
