In any subnet where wireless handsets are used, each subnet must have one or more WLAN IP Telephony Managers 2245. A WLAN IP Telephony Manager 2245 group on a subnet consists of one or more WLAN IP Telephony Managers 2245 and their associated wireless handsets. Only one master WLAN IP Telephony Manager 2245 can be on a subnet.

WLAN IP Telephony Manager 2245 groups

WLAN IP Telephony Manager 2245 groups are those that have more than one WLAN IP Telephony Manager 2245 in order to accommodate larger systems and a higher volume of wireless telephony traffic.

Master WLAN IP Telephony Manager 2245

In a group comprised of multiple WLAN IP Telephony Managers 2245, a master WLAN IP Telephony Manager 2245 must be identified and must be configured with a static IP address. The wireless handsets and the other WLAN IP Telephony Managers 2245 locate the master by using the static IP address of the master. The loss of a nonmaster WLAN IP Telephony Manager 2245 does not significantly affect the operation of the remaining WLAN IP Telephony Managers 2245. However, the loss of the master WLAN IP Telephony Manager 2245 results in a loss of all communication between all the WLAN IP Telephony Managers 2245. This causes the loss of all active calls, and wireless handsets cannot check in until communication with the master is reestablished.

Group capacities

The number of calls that an individual WLAN IP Telephony Manager 2245 can support is dependent on the number of WLAN IP Telephony Manager 2245s in the subnet. Assuming that a 100 Mb/s full-duplex connection to the network exists, a single stand-alone WLAN IP Telephony Manager 2245 can manage up to 80 active calls. If two WLAN IP Telephony Manager 2245s are installed in a master/slave configuration, each can support up to 64 active calls for a total of 128 calls.
