asterisk users - Feb 2013 - About Asterisk with Digium TE405P PRI ISDN cad

Hello,

I am trying to connect two asterisks with PRI connection. One asterisk has
TE405P Quad PRI ports card, anther asterisk has TE110P 1 PRI port card.

I am wondering if there would be some step by step guide that I could
follow to to this kind of connection?

Thanks

Hi,

I think, you mean connecting the two boxes directly with a cable... not 
via PSTN, right?

1.) You need a special cross-over cable to connect one Port directly to 
another Port...
(if you want to crimp it yourself, you can find the associated Pins via 
Google... ethernet crossover
cables do not work as they have different links)
2.) configure one end as master (CPN) and the other asterisk as Network 
(CPN), otherwise
you?ll get timing issues...

thats all...

regards,
yves

If you want to connect the two boxes together via the telephone network, then 
you will need appropriate NTEs  (Network termination Equipment -- the boundary 
between where the telco's responsibility ends and yours begins)  installed, 
and the telco should give you cables -- or at least advise on wiring.  
Connecting an Asterisk card to an NTE requires a straight-through cable.

If you just want to connect the boxes directly  (aot via the telephone 
network)  then you will need to make up a special cable.  Get CAT5 cable, 
plugs and crimping tool.  (If you are especially lazy, you can even just cut 
the plug off one end of a pre-wired CAT5 cable, and crimp your own in place of 
where it used to be.)  Now you need to swap over pin 1 (WHITE/orange) with pin 
5 (WHITE/blue) and pin 2 (ORANGE/white) with pin 4 (BLUE/white).  It won't
do
any harm leaving pins 3, 6, 7 and 8 connected, and it will make crimping up 
the plugs easier.


One end:  Standard wiring.
1: WHITE/orange 2: ORANGE/white 3: WHITE/green 4: BLUE/white 5: WHITE/blue 6: 
GREEN/white 7: WHITE/brown 8: BROWN/white

Other end:  Special wiring for ISDN crossover.
1: WHITE/blue 2: BLUE/white 3: WHITE/green 4: ORANGE/white 5: WHITE/orange 6: 
GREEN/white 7: WHITE/brown 8: BROWN/white


Don't forget, one of the machines has to be told  (in chan-dahdi.conf)  to 
pretend it is an NTE rather than subscriber's equipment!

Yes I made a special cross-over cable according to PRI cable pattern.

I think I lack of some ISDN basic knowledge I am trying to follow the article
from http://www.cadvision.com/blanchas/Asterisk/DahdiT1trunk.html to do this
task.

And I face some general question, for example :

According to
http://www.facebook.com/photo.php?fbid=10151387245397906&set=a.10151387218792906.496748.736667905&type=3&theater
 It is a screen shot of one "Span" of a TE405P card from DAHDI tools.
I am wondering if there are some document explain what different configurations
means, for example, Current Alarms, Sync Source IRQ Misses, etc?.


Thanks f
