AVAYA IP Office DECT & Wireless IP

Based on the Digital Enhanced Wireless Telecommunications (DECT) standard, Avaya IP Office's DECT wireless systems support the Generic Access Profile (GAP) standard designed to allow interoperability of handsets supplied by various suppliers. Delivering on site mobility for staff on the move, DECT is a digital solution designed to integrate with IP Office to provide roaming extensions on both IP Office and alternative vendors' PBXs.

There are three DECT options on IP Office:

Compact DECT Control Unit
Connects to the Avaya IP Office via analogue extension ports with a maximum of 8 DECT telephones.
DECT Control Unit (DCU)
Connects to the Avaya IP Office via analogue extension ports with a maximum of 128 DECT telephones.
Avaya IP DECT
A solution which consists of multiple DECT bases stations connected to the Avaya IP Office via IP trunks. Note that Avaya IP DECT equipment is not compatible with the Avaya DECT equipment above, with the exception of the 20DT telephone which does provide basic functionality when used with Avaya IP DECT system.

Avaya Compact DECT

The Compact DECT Control Unit (CU) is a wall mounted central equipment unit that both incorporates a base station and provides the control functions and interfaces to the IP Office system (or alternative PABX). The Compact DECT CU solution supports a maximum of 8 wireless handsets and 7 DECT Base Stations (DBS) [1 Main base station plus 6 repeaters]. The Compact DECT CU is connected to the IP Office control cabinet by 2 wire analogue extension ports and to a PC via a V24 control link enabling enhanced feature integration. The V24 control link enables the IP Office system to offer sophisticated features on the DECT handsets thanks to the intelligent LAN connection.

When connected to IP Office, the Compact DECT CU offers unique integrated features and continues to provide many of the functions associated with fixed IP Office digital phones without confining users to their desks.

The Compact DECT CU can be deployed up to 300m from the IP Office system providing coverage of up to 600 meters, depending on building construction and local environment. The average radius coverage within buildings is approximately 50m to 60m. The installation of the Compact DECT CU is very straightforward and simply requires a connection to local power and the associated IP Office.

In an area with a requirement for high wireless densities the Compact DECT CU should be located centrally with Repeater Base Stations being used to extend the coverage area over the site.

Extending Compact DECT Coverage

The coverage offered by the Compact DECT CU can be supplemented by up to 6 DECT Repeater Base Stations.

The Repeater Base Station is able to offer an extension to the area serviced by IP Office's DECT system in a simple and cost effective manner without the need to lay more cables.

Both Compact DECT CU and Repeater Base Station designs are very compact and may be installed out of sight within false ceilings. Local power is required for the Repeater Base Stations.

As with the standard DECT Base Station, the Repeater Base Station offers seamless handover and roaming enabling users to move freely between cells during calls over an extended area.

Each Repeater Base Station has a capacity of two simultaneous calls while the main Central Compact Base Station supports 6 simultaneous calls.

Avaya IP DECT

This solution is only available in EMEA and APAC regions. The Avaya IP DECT solution provides businesses with a highly functional wireless solution with the ability to scale to support large numbers of users. This system also supports users in different offices connected via a WAN. The Avaya IP DECT solution radio fixed part (RFP) or base station connects to the Avaya IP Office using an IP protocol based on H.323.

The Avaya IP DECT solution supports up to 120 handsets and 32 base stations. Each base station can be powered over the LAN using the Power over Ethernet (PoE) standard. Each indoor base station can also optionally be connected to main power via an external power adaptor. Each outdoor base station can only be powered using PoE - no individual power supplies are available to power the outdoor IP DECT base station.

This system supports the Avaya 3701 and Avaya 3711 handsets. The 20DT handset is also supported, but with minimal functionality – a special version of Message Waiting Indication is supported, but other features are not. For example: Access to the system directory will not work on the 20DT handset when used with this new solution. Avaya recommends that for new deployments, for full feature functionality the 3711 handset be used with the IP DECT solution.

Each Base station has the following features:

Frequency range: 1,880 – 1,900 GHz.
10 carrier frequencies (1,728 MHz spacing) with 12 time slots each.
Maximum transmission power of 10 mW.
8 simultaneous Voice and up to 12 Signalling Channels.
Codec G.711, G.723, G.729 for base station IP trunk connection.
Handover: While in motion, the handset performs continuous measurements to determine which IP DECT 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 IP DECT 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 IP DECT controller remains at one “headquarters” location. 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:
- 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
  Added in IP Office 3.1, 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 Comparison

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

DECT Licenses

Compact DECT and DECT DCU Systems

For these systems, the following additional features are available through the use of a CTI DECT licence and Avaya IP Office DECT Integration software running on a PC. The license is entered into the IP Office configuration

Available with 20DT sets only.
Desktop and Mobile Handset Twinning - The desktop and DECT handset can be synchronized to logically act as a single unit. Calls presented to the desktop phone will simultaneously be presented to the DECT handset. When either device is busy any further calls presented will receive busy tone or be rerouted to the relevant divert on busy destination which may be Voice Mail if configured. The integration of the devices extends beyond status information to incorporate more detailed feature integration including the simultaneous presentation of voice mail indication.
Other advanced features - Wireless users require many of the standard, as well as advanced, functions available to users of Desktop handsets. All telephone users, including mobile, have access to the system codes on IP Office and are therefore able to benefit accordingly. However, IP Office offers a number of enhanced features in conjunction with both wireless options detailed above. The variety of features addresses the needs of even the most sophisticated user.

These enhanced functions include:

CLI/ANI Presentation or associated name
Voicemail Message Waiting Indication
Intuitive Voice Mail Access
Call Waiting Indication
Presentation of Calling/Called Party Identity
Access to both Internal & External Directories for simplified dialing
Parallel ringing, vibration support and user definable ring cadence with a fixed phone (twinning).

Avaya IP DECT System

For this system, a license is necessary for even basic functionality. This license is called the Avaya IP Office IP DECT Mobility Manager license. This license is entered through the main base station (ADMM) and is NOT entered through the IP Office System manager. A feature key server is NOT necessary to enable the IP DECT functionality.

No separate PC or software is required with this system.

The Avaya IP DECT system is sold in bundles that are supplied complete with the licenses for new installs. For new installations the bundles will be the only license related items that should be purchased, along with the requisite numbers of telephones and base stations.

Additional upgrade licenses are available for systems that need to expand their current coverage or capacity.
