Cisco 1751 Router Software Configuration Guide

OL-1070-01

Sample Display

The following output shows the DSP timestamp and the router timestamp for each event and, for

SIG_STATUS, the state value shows the state of the ABCD bits in the signaling message. This sample

shows a call coming in on a foreign exchange office (FXO) interface.

The router waits for ringing to terminate before accepting the call. State=0x0 indicates ringing; state

0x4 indicates not ringing:

router# debug vpm dsp

ssm_dsp_message: SEND/RESP_SIG_STATUS: state=0x0 timestamp=58172 systime=40024

ssm_dsp_message: SEND/RESP_SIG_STATUS: state=0x4 timestamp=59472 systime=40154

ssm_dsp_message: SEND/RESP_SIG_STATUS: state=0x4 timestamp=59589 systime=40166

The following output shows the digits collected:

vcsm_dsp_message: MSG_TX_DTMF_DIGIT: digit=4

vcsm_dsp_message: MSG_TX_DTMF_DIGIT: digit=1

vcsm_dsp_message: MSG_TX_DTMF_DIGIT: digit=0

This shows the disconnect indication and the final call statistics reported by the DSP (which are then

populated in the call history table):

ssm_dsp_message: SEND/RESP_SIG_STATUS: state=0xC timestamp=21214 systime=42882

vcsm_dsp_message: MSG_TX_GET_TX_STAT: num_tx_pkts=1019 num_signaling_pkts=0

num_comfort_noise_pkts=0 transmit_durtation=24150 voice_transmit_duration=20380

fax_transmit_duration=0

debug vpm error

Use the debug vpm error command to enable DSP error tracing in voice port modules (VPMs). Use

the no form of this command to disable DSP error tracing.

[no] debug vpm error

Usage Guidelines

Execution of no debug all will turn off all port level debugging. You should turn off all debugging and

then enter the debug commands you are interested in one by one. This will help avoid confusion about

which ports you are actually debugging.

debug vpm port

Use the debug vpm port EXEC command to limit the debug output to a particular port. Use the no form

of this command to disable debugging output.

[no] debug vpm port slot-number/port
