WLAN IP Telephony Manager 2245 failure

The self healing software enhancement eliminates the need for manual intervention if a WLAN
Telephony Manager 2245 fails. The wireless handsets are configured with the IP address of a
designated WLAN Telephony Manager 2245. As the wireless handsets register, they receive
a list of IP addresses of other WLAN Telephony Manager 2245 in the network and they
distribute among other WLAN Telephony Manager 2245 to share the load. This WLAN
Telephony Manager 2245 becomes the registration point. The list of addresses automatically
updates each time the wireless handset powers on.
If the WLAN Telephony Manager 2245 fails, the wireless handset drops active calls, then re-
registers with another WLAN IP Telephony Manager 2245 in their list. The wireless handsets
return to active state after this registration period. This failure does not affect other wireless
handsets registered on the other WLAN IP Telephony Manager 2245 units.
The recovery period for the wireless handsets on the failed WLAN IP Telephony Manager 2245
is approximately 60 seconds.
The entire network is inoperative when new software downloads to the network of WLAN IP
Telephony Manager 2245 units. When the download completes, the network comes back into
service automatically.
This functionality requires WLAN IP Telephony Manager 2245 minimum software release
174.034, WLAN Handset 2210/2211/2212 minimum hardware version 97.071, and Avaya
6120/6140 WLAN Handset minimum hardware of 115.015. If any component is at an earlier
release then the system works in the current master or slave mode.
The failed WLAN IP Telephony Manager 2245 displays an alarm on its front panel and on an
Administrative Console (if used). Wireless handsets associated with the unit display "No SVP
Response" until the wireless handsets re-register.

Replacing a WLAN IP Telephony Manager 2245

Failed master WLAN IP Telephony Manager 2245

If the master WLAN IP Telephony Manager 2245 fails, no telephone calls can be made or
received on that subnet. To quickly restore functionality to the wireless telephone network,
Avaya recommends changing the configuration of a slave WLAN IP Telephony Manager 2245
to the configuration of the master. Then reset all the other slave WLAN IP Telephony Manager
