function as members) can be accommodated per Mobility Domain.
Using WL1700-MS as a seed, up to six WL Controllers (five WL Controllers function as
members) can be accommodated per Mobility Domain.
However, when using WL1700-MS, Mobility Domain configured with only WL1700-MSs
is available.

Voice Extension

To create a high-quality voice speech in a wireless network, UNIVERGE WL
System supports the following functions:

Voice QoS

The UNIVERGE WL system realizes a robust voice communication Quality of
Service (QoS) by dynamically controlling frame-transmitting intervals and
transmitting voice packets for IP terminals in preference to other data.

Bandwidth Control

To ensure the voice quality of IP terminals, the UNIVERGE WL system controls
bandwidth used for voice communications by using Call Admission Control
(CAC) function, which assigns bandwidth for voice communications and
bandwidth for data communications. Thereby, system can give voice
communications the highest priority, maintaining high-quality conversations, and
ensure bandwidth for data communications.

Fast Handover

The UNIVERGE WL system realizes a fast and seamless handover by using the
suitable switchover to another Access Point and tunnelling function even when an
IP terminal moves from one Access Point or subnet to another.

Voice Terminal Power Saving Control

UNIVERGE WL Controller provides a cooperation function with IP terminal and
wireless LAN voice terminal can sleep during call and waiting. Therefore, a
wireless LAN voice terminal can save power and extend duration of waiting and
talk time.
