Designating wireless telephone types
Unless there is another preferred use for the DES (Designator) prompt in
LD 11, Nortel Networks recommends using the DES prompt to indicate the
type of WLAN Handset, either type 2210 or 2211, for the i2004 type of
virtual line TN. This allows support personnel to enter 2210 or 2211 at the LD
20 DES prompt and receive a list of WLAN Handsets 2210 or WLAN
Handsets 2211 that have been configured on the Call Server.
The WLAN IP Telephony Manager 2245 controls the media stream and
blocks calls due to bandwidth constraints on any AP without notifying the
Call Server.
• The WLAN IP Telephony Manager 2245 can be configured with the
maximum number of simultaneous calls allowed on a single AP.
• On an incoming call for a wireless handset associated with a full AP, the
caller hears ringback and the Call Forward No Answer (CFNA)
treatment is applied, such as forwarding the call to voicemail. The called
party is not notified of the incoming call.
• If the call originates from a wireless handset which is on a
bandwidth-restricted AP, the caller hears a warning tone and the call is
blocked.
• If a wireless handset moves into an area serviced by an AP which is
already at capacity, the wireless handset will not associate with the new
AP. Instead, the wireless handset attempts to remain associated with an
AP that has sufficient bandwidth. This could result in packet loss,
degraded signal and voice quality, and a call could be dropped.
• UNIStim signaling, such as watchdog updates or lamp audit, are not
affected by the bandwidth constraint.
