204 Appendix B Troubleshooting WLAN IP Telephony installations
ATTENTION
Numbers racing across the handset display indicate that AP information is being
obtained. A Waiting message indicates that the system is not configured properly
and the handset cannot find any APs.
Diagnostics Mode
Diagnostics Mode evaluates the overall quality of the link between the
handsets, AP, and the infrastructure equipment (call server, WLAN IP
Telephony Manager 2245, and gateways). Diagnostics Mode can be used
when the handset is active.
When Diagnostics Mode is activated in the Admin menu, the handset enters
the diagnostic state. The handset can display diagnostics any time it is
on a call.
Pressing the Menu key displays a number of diagnostic counters. Five
screens of counters can be displayed by pressing the Menu key to scroll
through the following screens:
• Screen 1—displays counters for missed receive packets, missed
transmit packets, receive retry count, and transmit retry count.
• Screen 2—displays jitter delta, last successful transmit data rate, and
gateway type.
• Screen 3—displays a list of APs and some of their details.
• Screen 4—displays association and reassociation counts.
• Screen 5—displays security error count and sequence number for last
security error.
After all the counters are displayed, the screen returns to the normal
off-hook display.
The screen number appears on the top line of the screen.
Diagnostics Screen 1 displays the following information:
MissedRcvCnt nnnnn
MissedXmtCnt nnnnn
RxRetryCount nnnnn
TxRetryCount nnnnn
where
MissedRcvCnt is the missed receive packet count since power up.
MissedXmtCnt is the missed transmit packet count since power up.
RxRetryCount is the receive retry count since power up.
