simple networking equipment between the WLAN IP Telephony Manager 2245 and the
phones as possible.

WLAN IP Telephony Manager 2245 planning

Both the WLAN IP Telephony Manager 2245 and the WLAN Application Telephony Gateway
2246 are connected to the Ethernet switch.

Installation requirements

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 can autonegotiate to the
type of port on the Ethernet switch. It supports 10BaseT, 100BaseT, full-duplex and half-
duplex port types.
Avaya recommends 100BaseT full-duplex.
Important:
When multiple WLAN IP Telephony Manager 2245 units are used, all the WLAN IP
Telephony Manager 2245 units must use a uniform media type. Do not use full-duplex on
some and half-duplex on others, or 10BaseT on some and 100BaseT on others.

Capacities

The WLAN IP Telephony Manager 2245 is available in three models:
• WLAN IP Telephony Manager 2245-80: Serves 500 powered-on handsets (80
simultaneous calls).
• WLAN IP Telephony Manager 2245-20: Serves 20 powered-on handsets.
• WLAN IP Telephony Manager 2245-10: Serves 10 powered-on handsets.
Capacity is measured by active calls for the WLAN IP Telephony Manager 2245-80 and by
powered on handsets for the WLAN IP Telephony Manager 2245-10 and the WLAN IP
Telephony Manager 2245-20. The capacity of a system that is not based on 100Base-T, full-
duplex is lower. Avaya recommends that you not use older technology equipment.
In any subnet where wireless handsets are used, each subnet must have one or more WLAN IP
Telephony Manager 2245 units. A WLAN IP Telephony Manager 2245 group on a subnet
consists of one or more WLAN IP Telephony Manager 2245 units and their associated wireless
handsets.
Only one master WLAN IP Telephony Manager 2245 can be on a subnet.
