[asterisk-users] How to Understand a pri intense debug span X

[Danny Dias]

Hello my friends,

I would like to understand the output from "pri intense debug span X", the
Telco always says that their side is OK, but i always receive alarms,
loosing connection, take a look:

[Sep 16 13:18:19] WARNING[30364] chan_zap.c: Detected alarm on channel 1:
Recovering
[Sep 16 13:18:19] WARNING[30364] chan_zap.c: Unable to disable echo
cancellation on channel 1
[...]
[Sep 16 13:18:24] NOTICE[30363] chan_zap.c: PRI got event: No more alarm (5)
on Primary D-channel of span 1

So, i'm working with pri intense debug span X, but the output is quite
difficult to understand, what should i check from this output? Where should
i find some information in order to make a debug and talk to my telco with
"power" :)

Here is an example of pri intense debug span:

< Supervisory frame:
[Sep 16 13:59:25] < SAPI: 00  C/R: 0 EA: 0
<  TEI: 000        EA: 1
[Sep 16 13:59:25] < Zero: 0     S: 0 01: 1  [ RR (receive ready) ]
< N(R): 024 P/F: 1
< 0 bytes of data
[Sep 16 13:59:25] Handling message for SAPI/TEI=0/0
[Sep 16 13:59:25] -- ACKing all packets from 23 to (but not including) 24
[Sep 16 13:59:25] -- Since there was nothing left, stopping T200 counter
[Sep 16 13:59:25] -- Stopping T203 counter since we got an ACK
[Sep 16 13:59:25] -- Nothing left, starting T203 counter
[Sep 16 13:59:25] -- Got RR response to our frame
[Sep 16 13:59:25] -- Restarting T203 counter

Thanks in advance
