Avaya 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.

The solution consists of:

• Four wireless handsets (3720, 3725, 3740 and 3749)
• Two radio base stations (with internal and external antennas) with IP interface for usage with IP Office
• A 4-channel Compact base-station for small installs, up to 5 can be used per system.
• An IP DECT Gateway to enable an IP connection with IP Office and ISDN connection with radio 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.

The Avaya DECT R4 solution on IP Office supports up to 1.000 handsets and 120 base stations. Aura ACM supports up to 10.000 handsets and 1.000 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. Both base-stations can be installed in an outdoor housing to provide an "external" base-station.

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 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, 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.
• 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.
