Wireless - DECT R4

The Avaya DECT R4 solution delivers the productivity-boosting benefits of IP and wireless communications across multiple offices in a convenient, lightweight handset. It 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 DECT R4 solution radio fixed part or IP base station (IPBS) connects to the IP Office using an IP protocol based on H.323.

Avaya’s DECT R4 solution features all advantages of a full blown DECT solution for the enterprise market: Cost effective high wireless voice quality in a frequency band exclusively reserved for DECT that is secure, easy to deploy and enhance.

New with R6:

Access to the IP Office directory has been moved back to the master base-station, therefore an AIWS server is not required if only IP Office directory access is needed. Please note that AIWS is still needed for all other additional functionalities like handset to handset SMS and remote software upgrade.
New four-channel Compact Base Station for small installs and low users counts

The solution consists of:

Two wireless handsets.
Two 8-channel radio base stations (with internal and external antennas) with IP interface for usage with IP Office.
A cost efficient entry level base station “Compact” that support up to 4 channels. A system is limited to 5 of the RBS Compact at each time, expansion beyond 5 RBS is possible but requires the larger Base-stations.
An appliance server for centralized functions like corporate directory and internal phonebook access, simple text messaging, integration of messaging and other external applications, centralized configuration and maintenance etc.

As the solution contains a handset with liquid protection and BlueTooth headset interface and an appliance server for attaching messaging applications it is especially well suited for verticals like healthcare and retail.

All handsets and radio base stations support the DECT frequency bands in EMEA, APAC, NAR and CALA with the same hardware and firmware. (Please check type approval for availability in the different regions)

The Avaya DECT R4 solution on IP Office 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 base station can be also powered by an external power supply. There are two versions of the base station (IPBS) available:, a standard base station with fixed antennas and an enhanced base station with a variety of external antennas (External antenna not available in the US).  Both base-stations can be installed in an outdoor housing to provide an "external" base-station

Solution Overview

DECT R4 System

In all approved regions, this system supports the 3720 and 3725 handsets.

IP DECT Radio Base Station (RBS)

The DECT R4 Radio Base Stations are used with IP Office only. It connects directly to a LAN switch using Ethernet cabling. The DECT R4 Radio Base Stations can either be powered by Power-over-Ethernet or by using external power supplies that are available as accessories.

Each standard DECT R4 Radio Base Station can handle up to eight concurrent calls while each Compact Radio Base Station can handle up to 4 concurrent calls. A special protocol called on-air synchronization ensures that active calls are seamlessly handed over from one DECT R4 Radio Base Station to the next one if a user with an active call roams through a building.

To make sure that the on-air protocol works and that the whole building is covered by the ranges of the DECT R4 Radio Base Stations a site survey is needed to determine the number and placement of the DECT R4 Radio Base stations within the building. Avaya offers these site surveys as a service offer by AGS as well as measurement kits for business partners who want to do these site surveys on their own.

The on-air synchronization as well as the access to the phonebook of IP Office is done by a special software (master server) that can run in parallel to the standard DECT R4 Radio Base Station software on the same hardware.

DECT R4 Radio Base Station with internal antennas

DECT R4 Radio Base Station with external antennas

Each base station has the following features:

Two variants of the standard Radio Base Station: With Internal antenna and with External Antenna due to regulation, in the US only the base-station with internal antenna may be used.
There are several antennas available for the base-station with external antenna: Standard, Directional Single, Directional Dual, Omnidirectional.
One variant of the Compact Radio Base Station with internal antennas. The compact base station has the same look and feel as the base station with internal antenna.
Outdoor housing available for both versions
8 Simultaneous voice and up to 12 signaling channels for the standard Radio Base Stations.
4 Simultaneous voice and up to 12 signaling channels for the compact Radio Base Stations.
Codec G.711, G723, G.729a/b for base station IP trunk connection.
Power Consumption
Power over Ethernet or local power supply supported
Power over Ethernet, IEEE 802.3af, class 2, typical 4W, maximum 5W consumption.
Dimension: 200 (w) x 165 (d) x 56 (h) mm including mounting bracket
Weight RBS: 450g.

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 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.
