Network planning
It is necessary to ensure that all connections and interfaces for the
IP Telephony network be configured as full-duplex. Duplex mismatches
anywhere on the WLAN can cause the wireless IP Telephony system not to
function normally.
Zones
Nortel Networks recommends that the WLAN Handsets 2210/2211 be
assigned to dedicated zones. The zones can be used to manage the bandwidth
of the WLAN IP Telephony Manager 2245 groups. As well, zone
designations can be used to list the wireless handsets that are currently
registered or have been registered using LD 117 commands.
For more information, refer to “Bandwidth management” on page 52.
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 auto-negotiates to the type of port on the Ethernet switch. It
supports 10BaseT, 100BaseT, full-duplex and half-duplex port types.
Nortel Networks recommends 100BaseT full-duplex.
Note: When multiple WLAN IP Telephony Managers 2245 are used, all
the WLAN IP Telephony Managers 2245 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.
