26Overview

Employees carry wireless handsets to make and receive calls as they move throughout the building. The handsets are used only on the premises; they are not cellular phones. The handsets communicate with the CS 1000 and with the WLAN IP Telephony Manager 2245. Just like wired telephones, the wireless handsets receive calls directly, receive transferred calls, transfer calls to other extensions, and make outside and long-distance calls (subject to corporate restrictions).

The handsets interoperate with other IP Line and IP Trunk features and devices, such as IP Peer, and the IP Phone 20xx and IP Softphone 2050 series of IP Phones, with the exception of some media-related constraints described in "Codecs" (page 79).

The frequencies that are allocated are governed by IEEE guidelines for WLANs and are part of the free spectrum. The WLAN Handset 6120/6140 uses a, b, and g frequencies, and the WLAN Handset 2210/2211/2212 uses the b frequency.

The handsets work only in a Nortel Succession 3.0 (and later) environment coordinated with a Communication Server (CS) 1000 or Business Communications Server (BCM). These handsets communicate with the Nortel call server through the Unified Network IP Stimulus (UNIStim) protocol. The media path of the voice call goes from the handset directly to the destination device (through the WLAN Telephony Manager 2245). In addition, the handset encapsulates all traffic in the SpectraLink Voice Priority (SVP) protocol. The WLAN Telephony Manager 2245 deencapsulates the VoIP traffic from SVP and passes it onto the network—it does not translate between UNIStim and SVP. Therefore, the Telephony Manager 2245 is in the path of all communication to and from the handset. Likewise, signaling goes from the handset to the Telephony Manager 2245 to the call server.

The WLAN Handset 2211 and the WLAN Handset 6140 are the most durable and they are the only handsets that support Push-to-talk (PTT).
