Hi Christopher,<br>
This may seem like a daft suggestion, but why not set the asterisk
box to use ss7 signaling ?<br>
It sounds like you're using the same style of hardware that I am (ie, a
server with a TE410P card)<br>
so it shouldn't be hard to configure asterisk to use ss7 instead of
ISDN PRI.<br>
<br>

Mark.<br>

<pre wrap="">I see. I thought you were basically setting up a SS7 to ISDN converter to
replace the effect of a signaling converter box. You see, I have four E1s
which use SS7 signaling and I am looking to convert them to ISDN before
plygging them into my TE410P card in asterisk box. I thought you were using
a TE410P as the converter.

Chris

to test that I could get the ss7 linksets configured and pass calles
over them.
I use the crossover cable to connect the two ss7 linksets together.

Hi Christopher,
I'm not sure I understand your question.
What I have set up for testing SS7 is as follows :-
SS7 Linkset 1 comes out of TE410P span 1, via a T1/E1 crossover cable into
span 2 of the same TE410P to SS7 Linkset 2
Regards
Mark.

How were you able to go from two SS7 linksets into the TE410P E1 card to a
single ISDN after conversion on the crossover link?
Did you not have traffic congestion problems when going from 2 to 1 ?
Unless an SS7 linkset is equivalent to half an E1 ?
