Overview Description The Nortel Networks Wireless Local Area Network Handsets 2210 and 2211 (WLAN Handsets 2210/2211) operate over an 802.11b wireless Ethernet LAN providing users a wireless Voice over IP (VoIP). The WLAN Handsets 2210/2211 emulate the Nortel Networks IP Phone 2004 to provide the VoIP functionality.
Figure 1 Basic network configuration The basic WLAN IP Telephony network consists of the following components: • • • • • • BCM (call server) TFTP Server (optional) DHCP Server (optional) WLAN IP Telephony Manager 2245 WLAN Handset 2210/2211 Access Point (AP) BCM To support the WLAN Handsets 2210/2211, the BCM system must run Release 3.6.1 (patch) or later software versions. BCM systems with 3.6 or earlier software versions must be upgraded to support the handsets.
If too many wireless handsets are attempting to download new firmware simultaneously, the downloads can slow down or error messages can be returned. To reduce the number of retries and error messages, manage the download process by staggering the times the wireless handsets download the firmware. The TFTP Server must be capable of supporting multiple TFTP sessions. Nortel Networks has tested the following TFTP Servers. They are listed in order of preference.
The IP-related parameters of the WLAN Handsets 2210/2211 can be configured manually or through a DHCP Server (RFC 1541 and RFC 1533). The DHCP Server can be on either side of the firewall, according to the site administrator’s preference. The DHCP Server is optional if the WLAN handsets and WLAN IP Telephony Manager 2245 are statically configured. Each wireless handset effectively uses two IP addresses in the wireless subnet.
Firewall In many installations there will be a firewall installed between the wired and wireless parts of the network. It is beyond the scope of this document to specify how a firewall is managed, but the following guidelines can be used when configuring firewalls: • • The TFTP Server, DHCP Server, and Syslog Server can be anywhere in the network (that is, they are not restricted to being in the same subnet as the handsets and WLAN IP Telephony Manager 2245).
The WLAN IP Telephony Manager 2245 works with the APs to provide QoS on the WLAN. All voice packets are encapsulated by the WLAN handsets. The encapsulated voice packets to and from the WLAN handsets are handled by the WLAN IP Telephony Manager 2245 and routed to and from the BCM. SVP is the QoS mechanism implemented on the WLAN handsets and APs to enhance voice quality over the wireless network.
• • • • — COL - lit if there are network collisions NETWORK - connects the WLAN IP Telephony Manager 2245 to the wired Ethernet LAN ERROR LED - lit when the system has detected an error Status LED - indicate system error messages and status — 1 - heartbeat — 2 - active calls — 3, 4, 5 - currently unused PWR - connects to the AC adapter supplying power to the system Warning: Use only the provided Class II AC adapter with 24 volt (V) DC, 1 amp (A) output.
• • • 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.
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.
Mobility across different subnets when using DHCP If a WSS is not in use, and the IP address of the wireless handset has been acquired through DHCP, the wireless handset must be powered down and powered up when entering a new subnet. This enables functionality of the wireless handset when entering the WLAN RF signal coverage area of a different WLAN IP Telephony Manager 2245 group on a different subnet.
It is essential to know where to install the APs to provide effective coverage for the WLAN handsets. The first step is to define exactly where the coverage is needed, which requires a site survey. Refer to “Appendix D: Provisioning” on page 113 for information on site planning. Tips: A site survey must be performed before installing a wireless LAN. Nortel Networks also recommends a site survey when an existing network structure is modified or when physical changes are made to a site.
IP addressing with DHCP A pool of alias IP addresses must be configured on the WLAN IP Telephony Manager 2245 for the use of the wireless handsets. Refer to “Functional description” on page 35 for information on IP addresses on the WLAN IP Telephony Manager 2245. The use of a 22-bit subnet mask provides IP addresses for approximately 500 wireless handsets (1024 nodes). Allocate a pool of an equal number of IP addresses on the DHCP Server and WLAN IP Telephony Manager 2245 for the wireless handsets.
WLAN IP Telephony Manager 2245 installation This section explains how to install the WLAN IP Telephony Manager 2245. For an overview of the WLAN IP Telephony Manager 2245, refer to “WLAN IP Telephony Manager 2245” on page 33.

• • — DHCP option 151 — DNS lookup of “SLNKSVP2” if the DHCP options 6 (DNS Server) and 15 (Domain Name) are configured. Server 1 IP – the published IP address of the BCM. If the wireless handset is using static IP address configuration, enter the published IP address of the BCM. If the WLAN handset is using DHCP, the DHCP Server must be configured to provide the published IP address (and UDP port number) of the BCM using one of the following DHCP options: 46, 128, 144, 157, 191, and 251.
• • Server 2 IP – the IP address of the secondary Nortel Networks device. Currently, the wireless handset does not make use of this information. If using Static IP configuration, this is simply the IP address of the device. If DHCP is being used, the wireless handset tries to obtain the device’s IP address and port information using the following DHCP options: 46, 128, 144, 157, 191, and 251. Server 2 Port – the port number used by the secondary Nortel Networks device to communicate with IP phones.
Restore Defaults The Restore Defaults option resets all user and administrative parameters to their factory defaults. During configuration, press the right arrow to skip this mode. Site Survey mode Site Survey Mode is used to check the signal strength from APs. Site Survey Mode must be set to 10 to make a connection. When Site Survey Mode is selected, the wireless handset remains in this mode until it is powered off. During configuration, press the right arrow to skip this mode.
! Security Note: Encryption codes display as they are entered. For security reasons, codes do not display when a user returns to the Admin Menu Encryption options. ! Security Note: WEP can be set to “optional” at the AP if there are wireless devices in use that do not have WEP capability. All wireless devices must be upgraded to WEP capability for a fully-secured WEP environment.
OAI on/off Nortel Networks Open Application Interface (OAI) enables the wireless handset to connect with the optional WLAN Application Gateway 2246. This device allows third-party computer applications to display alphanumeric messages on the wireless handset display and take input from the wireless handset keypad. If a WLAN Application Gateway 2246 is installed in the system, OAI may be optionally enabled in each wireless handset.
Pre-download checklist The following requirements must be met to download firmware by over-the-air file transfer: • • • • • • Α wireless LAN must be properly configured and operational through the use of 802.11b SVP-compliant wireless APs. Τhe Nortel Networks WLAN IP Telephony Manager 2245 must be connected to the network and completely operational. Α TFTP Server must be available on the network to load the appropriate firmware into the wireless handsets.
Programming the WLAN Handsets 2210/2211 The Line keys 1-6 on the WLAN Handsets 2210/2211 are programmable by the end user. These Line keys can be programmed in the wireless handset in the same manner they are programmed on the IP Phone 2004. Follow the steps in “Programming the Line keys” to program keys on the wireless handset. Programming the Line keys There are three menus available for the Line keys. The menu available is dependent on the state of the WLAN Handset 2210/2211.

System Uptime – the number of days, hours, and minutes since the WLAN IP Telephony Manager 2245 was last reset. Net – the type of connection to the Ethernet switch currently utilized. Displayed as 10 (10BaseT) or 100 (100BaseT)/half-duplex, full-duplex, or auto-negotiate.
• • • • • — carrier – carrier lost during transmission — collisions – packets deferred (delayed) due to collision SVP-II Access Points in Use – number of APs used by WLAN handsets, either in standby or in a call. ‘Last’ is current, ‘Max’ is the maximum number in use at one time. SVP-II Access Points in Calls – number of APs with WLAN handsets in a call. SVP-II Telephones in Use – number of WLAN handsets in standby or in a call. SVP-II Telephones in Calls – number of WLAN handsets in a call.
Duplex mismatch A duplex mismatch anywhere on the WLAN can cause the WLAN IP Telephony Manager 2245 to operate improperly. Double-check WLAN connections and interfaces to ensure that they are all configured as full-duplex. Feature limitations The following limitations exist for the WLAN Handsets 2210/2211: • • The WLAN Handsets 2210/2211 do not have handsfree capability. Therefore, any feature which requires handsfree is not supported or only partially supported.
• If a set is mobile and moves into an AP that is already at capacity, the handset remains associated with an AP that has sufficient bandwidth. This could result in degraded signal and voice quality and, ultimately, a call could be dropped. Tip: Nortel Networks recommends that you always press the End key after a call is completed — even if the party on the other end terminates the call.
Appendix A: Compatible Access Points Introduction Table 8 lists APs that are compatible with WLAN Handsets 2210/2211 operating on the WLAN IP Telephony Manager 2245. 802.11b APs generally support up to 12 simultaneous calls per AP.

Appendix D: Provisioning Site survey To conduct a site survey, set up an AP at a particular location. Use a computer equipped with a WLAN device and site survey software or a WLAN Handset 2210/2211 operating in Site Survey mode to measure the strength of the signal from the AP. Move the wireless device around and repeat the measurements to determine the optimum number and best locations for the APs.
Conducting an effective site survey Consider the following points for an effective site survey.
RF transmission testing Once the APs have been installed and configured, it is necessary to measure the strength of the RF transmissions. Signal strength testing ensures that all usage areas have adequate coverage. This can be performed in two ways. • • Use the WLAN Handsets 2210/2211 to determine AP signal strength using the Site Survey mode. Use two portable computers with wireless hardware operating on a point-to-point basis.
