[Asterisk-Users] T1 Channel splitting PRI/data not working

[Alexander Lopez]

For the poster place a test jack on the end that connects to the smart
jack. Make it as so:
Pin 1	-> 4
Pin 2 -> 5


This document will explain how to use the zaptel tools to run a pattern
loop on a zaptel interface (T1) with an external hard loop.

Please have a T1 loopback plug or jack with cable available.
The pin out should be pin 1 -->4 and pin 2 -->5.  
Make sure the span is in OK (no alarms) then configure the span as
follows in zaptel.conf: 

span = 1,0,0,esf,b8zs

clear = 1-24

Then run ztcfg -vv to configure the channels.  The channels must be
configured for esf/b8zs and each span needs it's own clear = x-x line. 

Now you can build and run the tests. 

cd /usr/src/zaptel
make tests

./patlooptest /dev/zap/1 60
Going for it...
