PSTN call disconnected throught a PRI causes= 0x7F00 and 0xDF00

Hello,

A RAS is disconnecting PSTN calls with causes = 0x7F00 and 0xDF00

Can someone explain me thoses causes ?

All disconnected calls for 0x7F00 are very shorts ones.

Here are some SYSlog traces:

%MODEM_HIST-3-END_CALL: Mica Modem 1/11

Connect Protocol - LAPM, Compression - V42bis, Connected Standard - V90

Tx/Rx bit rate - 46666/28800

Call Time - 00:00:18, Disconnect Reason (0x7F00) - Host Disconnect

0 retrains and/or speed shifts, 0 ec retransmissions requested

0 chars tx, 0 chars rx, 20 chars rx bad

0 ppp packets tx, 0 ppp packets rx, 0 ppp packets rx bad

0 ec packets tx, 0 ec packets rx, 0 ec packets rx bad

0 v110 packets tx, 0 v110 packets rx, 0 v110 packets rx bad, 0 v110 sync loss

%MODEM_HIST-3-END_CALL: Mica Modem 1/5

Call Time - 00:26:49, Disconnect Reason (0xDF00) - Host Disconnect

1 retrains and/or speed shifts, 35 ec retransmissions requested

337516 chars tx, 525490 chars rx, 20 chars rx bad

1326 ppp packets tx, 1603 ppp packets rx, 0 ppp packets rx bad

2762 ec packets tx, 4441 ec packets rx, 0 ec packets rx bad

0 v110 packets tx, 0 v110 packets rx, 0 v110 packets rx bad, 0 v110 sync loss

the code 0xDF00 seems to be related to V110, but no V110 packets are seen.

Regards,

Re: PSTN call disconnected throught a PRI causes= 0x7F00 and 0xD

Here is the link which will explain you what are those disconnect cause codes stands for mica modems

http://www.cisco.com/warp/public/76/mica-states-drs.html

To troubleshoot more about the actual reasons, you need to turn on "modem call-record terse" or "spe call-record terse" in the global config. Based on that failed call records, we can see what actually is going on there. Above link also explains that.
