[Asterisk-Users] Siemens EWSD 13

[asterisk at geek.be]

Hi all,

Has anyone got any experience with hooking Asterisk up with a
Siemens EWSD 13 switch over a E1/PRI ?
We're located in Belgium (Europe) and one of our telecom partners 
uses this switch.

We connected one of our TE410P ports with their switch, but the status
light on the TE410P card keeps blinking red.
On their side they are getting a DSA (distance service alarm) error, so
this normally means the devices 'see' eachother.. but there are still
problems with the signalling.

Our config below is the same as we are using for MCI, one of our other
telecom partners.

We tried changing the LBO and timing, but no luck.
As you see the signalling is carried over channel 16 (default).

TX and RX have also been regularly switched, so no luck..

Their switch is providing the timing.

The telecom operator has double checked the asterisk config several
times, and it's conform to their setup.

The only thing they couldn't find in the Asterisk config is a
'multiframing' option. But I presume this is automatically detected or
set by default ?
They also tried normal/single(?) framing, but no difference.

The card has also been tested with our MCI E1, and works flawlessly, so
no hardware issue.

Anyone got any further ideas ?

Any info or help greatly appreciated!

Our config,

*** zaptel.conf ***
