Capacities

•RTP packets between the wireless telephone and the WLAN IP Telephony Manager 2245 always contain 30 milliseconds (ms) worth of voice, regardless of what has been configured on the BCM. The WLAN IP Telephony Manager 2245 repackages the RTP packets to conform to the size that has been configured in the BCM. This provides more efficient use of the available RF bandwidth at the expense of slightly increased jitter and latency.

•The WLAN IP Telephony Manager 2245 is configured with a maximum allowable number of simultaneous media streams on a single AP. The WLAN IP Telephony Manager 2245 keeps track of the number of media streams on each AP and blocks calls to and from a wireless handset that would exceed the configured capacity.

•There is a keep-alive packet exchange that runs between the wireless handset and the WLAN IP Telephony Manager 2245 every 30 seconds. If the wireless handset detects the WLAN IP Telephony Manager 2245 is unreachable, the wireless handset resets itself and attempts to re-establish a connection with the master WLAN IP Telephony Manager 2245, where there is more than one WLAN IP Telephony 2245 in the system.

The WLAN IP Telephony Manager 2245 requires a CAT5 cable connection between its network port and the Ethernet switch. The WLAN IP Telephony Manager 2245 auto-negotiates to the type of port on the Ethernet switch and supports 10BaseT, 100BaseT, full-duplex, and half-duplex port types.

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.

The WLAN infrastructure, if properly deployed, can support the same capacity offered in the BCM for IP terminals. When planning for WLAN set deployment, follow standard BCM IP terminal engineering practices. When planning your WLAN infrastructure deployment, follow your AP vendor’s standard voice deployment site survey practices.

WLAN IP Telephony Manager 2245 firmware upgrade

When a WLAN IP Telephony Manager 2245 reboots or is manually reset by the operator, the following occurs:

1The WLAN IP Telephony Manager 2245 checks its version of firmware against the version on the TFTP Server.

2If the firmware versions are different, the WLAN IP Telephony Manager 2245 downloads the new firmware.
