29 Overview Overview Description The Nortel Networks Wireless Local Area Network Handsets 2210 and 2211 (WLAN Handsets 2210/2211) op erate over an 802 .11b wireless Etherne t LAN providing users a wireless Voice over IP (VoIP). The WLAN Handsets 2210/2211 emulat e the Nortel Networks IP Phone 2004 to provide the VoIP functionality.
30 Overview Figure 1 Basic network configuration The basic WLAN IP Teleph ony network consists of the following components: • BCM (call server) • TFTP Server (optional) • DHCP Server (optional) .
31 Overview If too many wireless handsets ar e attempting to down load new firmware simultaneously, the downloads can slow down or erro r messages can be returned. To re duce the number of retries and error messages, manage the dow nload process by staggering the times the wireless handsets download the firmware.
32 Overview The IP-related parameters of the WLAN Handsets 2210/221 1 can be configured ma nually 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.
33 Overview Firewall In many installations there will be a firewall installed between the wired and wireless parts of the network. It is beyond th e scope of this document to specify how a firewall is.
34 Overview The WLAN IP Telephony Manager 2245 works with the APs t o provide QoS on the WLAN. All voice packets are encapsulated by the WLAN ha ndsets. The encapsulated voice packets to and from the WLAN handsets are handled by the WLAN IP Tele phony Manager 2245 and routed to and from the BCM.
35 Overview — COL - lit if there are network collisions • NETWORK - connects the WLAN IP T elephony Manager 2245 to t he wired Ethernet LAN • ERROR LED - lit when the system has detected an erro.
36 Overview • R TP packets between the wire less telephone and the WLAN IP T elephony Manager 2245 always contain 30 milliseconds (m s) worth of voice, regardless of what has been configured on the BCM. The W LAN IP T elephony Manager 2245 repackages the R TP packets to conform to the size that has been configured in the BCM.
37 Overview Feature P acka ging/Set Em ulation Model, IT T ype and Release Number The WLAN Handsets 22 10/2211 appear to the BCM as a standard IP Phon e 2004.
38 Overview Mobility across different su bnets 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 sub net.
39 Overview It is essential to know where to install the APs to provide effective coverage for the WLAN handsets. The first step is to de fine exactly where the coverage is needed, which requires a site survey. Refer to “Appendix D: Provision ing” on page 113 for information on site planning.
40 Overview 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 d escription” on page 35 for information on IP addresses on the WLAN IP Telephony Manager 2245.
