Overview
Feature Packaging/Set Emulation Model, IT Type and Release
Number
The WLAN Handsets 2210/2211 appear to the BCM as a standard IP Phone 2004.
The WLAN Handsets 2210/2211 have the following assignments:
• IT TYPE: 0x02
• Release Number 2210: 0x06
• Release Number 2211: 0x07
• Manufacturing ID: 30
• Color Code: 66
• DHCP Class Identifier: "Nortel-i2210-A" or "Nortel-i2211-A"
• PEC Code: NTTQ4010 for the 2210 and NTTQ5010 for the 2211
Roaming and handover
Roaming is the ability of the wireless handset to go anywhere in the WLAN Extended Service Set
(ESS) RF signal coverage area and to make and receive calls. Handover is the ability of the
wireless handset to maintain an active call without interruption while moving within a WLAN ESS
RF signal coverage area. This means that the wireless handset hands over the WLAN RF signal
from AP to AP without interrupting the data stream.
APs on the same subnet
The WLAN Handsets 2210/2211 can perform handover and roaming across SVP-compliant APs
that reside on the same subnet as the wireless handset and WLAN IP Telephony Manager 2245
group. Refer to Table 8 on page 77 for a list of SVP-compliant APs.
APs on different subnets using WSS
If you use Nortel Networks WSS 2250/2270 and Nortel Networks Access Ports 2230, both
operating in Layer 3 mode, the WLAN Handsets 2210/2211 can perform roaming and handover
across Access Ports 2230 on different subnets. The WSS 2270 operating in Layer 3 mode is on the
same subnet as the WLAN IP Telephony Manager 2245 group. The WSS 2270 allows the wireless
handset to retain its original IP address, whether the IP address was configured statically or
obtained by DHCP. This means that roaming and handover can occur across Access Ports 2230
placed on any subnet.
Note: The WSS 2270 must be running version 2.0.71.0 (or later) software.
