DECT Feature Overview

Given the degree of integration available to wireless users with DECT, there are a variety of means by which

calls can be routed to wireless handsets:

· Handover

While in motion, the handset performs continuous measurements to determine which DECT R4 base

station has the strongest signal. The one that can be best received is defined as the active Base station.

To prevent the handset from rapidly switching back and forth between two base stations that are equally

well received, threshold values are used. Handover between base stations occurs seamlessly whether a

call is active or not.

· DECT Networking

An DECT R4 telephone can travel from one office to another which is connected over a wide area

network (WAN) link and make and take calls. In this scenario the main DECT R4 controller remains at

one "headquarters" location, with slave base stations in up to 31 other offices.

· DDI/DID

Since each wireless handset is an extension on the IP Office system calls may be routed directly using a

DDI/DID number.

· Transfer

Calls may be transferred to DECT extensions by operators or other extension users and DECT extension

users may transfer callers to any other extension user.

· Hunt group compatibility

Wireless handsets may be programmed as members of groups and answer calls in the same manner as

any other extension within that group.

· Group working

Wireless handsets may be programmed as members of groups and attract calls in the same manner as

any other extension within that group. DECT handsets must NOT be configured into collective groups.

· Divert destination

Users may initiate any or all diverts from an Avaya desk phone to a wireless handset.

· Twinning

Twinning allows calls to a user main extension number to alert at both that extension and a secondary

extension. Though not restricted to DECT, this feature is aimed primarily at users who have both a desk

phone and a wireless extension. Calls from the secondary twinned extension are presented as if from the

users main extension. Presentation of call waiting and busy is based on whether either of the twinned

extensions is in use.

· DECT R4 Capacities:

Feature DECT R4

Maximum Handsets 120

Maximum Base Stations if Master Server is on a standard RBS 32

Maximum Base Stations if Master Server is on a Compact RBS 5

Total Base Stations/Compact Base Stations 32

Total number of Compact Base Stations 5

Maximum simultaneous calls 100*

*May be limited by the available VCM voice compression channels for calls to non-IP destinations.

DECT R4 on IP Office does not support Redundancy option.

· Licensing and Redundancy

Other then IP-Dect, Dect R4 does not require any licensing by itself (next to the licensing for the

appropriate VCM channels in IP Office). Dect R4 on IP Office does not support Redundancy option

DECT R4 Inbuilding Wireless Server (AIWS)

The Avaya Inbuilding Wireless Server enhances the functionality of the DECT R4 with additional functionality

such as IP Office and LDAP directory access, centralized management and software update as well as handset

to handset SMS plus basic web messaging.

Avaya In-Building Wireless Server (AIWS) is a server for handling wireless services and messaging. It runs on a

solid state embedded Server (AIWS Hardware). It comes pre-installed, with the appropriate features activated

on that server.

For installation and maintenance, this server is managed by a PC using Windows Internet Explore (6.0 or

above) and Sun’s Java Runtime Environment.

Several variants of the server are available. All Servers come fully installed and preloaded with licenses so no

extra installation is needed. There is no upgrade available from e.g. Basic to standard.
