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.

To be able to connect to the Business Communications Manager (BCM), the WLAN Handsets 2210/2211 must be supplied with the Internet Protocol (IP) address of the Nortel Networks WLAN IP Telephony Manager 2245 and, optionally, a Trivial File Transfer Protocol (TFTP) Server. The WLAN Handsets 2210/2211 accept IP address configuration parameters either from manual configuration or from a Dynamic Host Configuration Protocol (DHCP) Server. DHCP automatic discovery mode provides WLAN IP Telephony Manager 2245 and TFTP Server IP addresses to the WLAN Handsets 2210/2211. In addition, DHCP allows the Unified Manager (UM) and BCM Monitor to recognize the WLAN Handsets 2210/2211 as such. The BCM can be the DHCP Server, or a separate DHCP Server can be installed in the network.

The 802.11b protocol provides no mechanism for differentiating audio packets from data packets. The WLAN IP Telephony Manager 2245 provides a Quality of Service (QOS) mechanism that is implemented in the WLAN Handsets 2210/2211 and the Access Points (APs) to enhance voice quality over the wireless network. The WLAN IP Telephony Manager 2245 gives preference to voice packets over data packets on the wireless medium, increasing the probability that all voice packets are transmitted efficiently and with minimum or no delay.

The WLAN Handsets 2210/2211 use the TFTP Server to update the wireless telephone firmware over the 802.11b WLAN.

Note: In this document, Nortel Networks WLAN IP Telephony Manager 2245 refers to the SpectraLink Voice Priority (SVP) Server.

Note: For the purposes of this book, it is assumed that site planning and deployment is complete. A general description of the process is provided. This can assist you when troubleshooting. See “Appendix D: Provisioning” on page 113.

Network configuration

There are many possible configurations for a WLAN IP Telephony network. A typical configuration is shown in Figure 1 on page 30.
