DECT R4:

1. DECT R4

Avaya DECT R4 is a DECT system where multiple base stations are connected using an IP LAN. For IP Office, DECT R4 is supported with IP Office Release 5+. This installation manual covers the installation of DECT R4 systems using the firmware supported by IP Office Release 7.0.

· IP DECT Base Station (IPBS) Up to 32 are supported. During installation one is configured as the master base station, to which the other base stations synchronize as slave base stations. Each base station can host up to 8 simultaneous phone conversations in its coverage area.

· For IP Office Release 6 and higher, the Compact Base Station is supported. This type of base station only supports 4 simultaneous calls. Up to 5 Compact Base Station units can be included in a system. If used as the master base station, the whole system is limited to 5 base stations.

· Phones Up to 120 DECT phones are supported. The Avaya 3700 Series phones supported are the 3720, 3725, 3740 and

3749. Other DECT phones, including the 3701 and 3711, are supported but only for basic telephony and only using the DECT GAP and DECT CAP standards.

· Chargers A number of different types of charger exist for 3700 Series phones. Note that chargers for 3720/3725 phones are not necessarily useable with 3740/3749 phones.

· Basic Charger This is a simple single-phone charger for charging only.

· Advanced Charger This single-phone charger has USB and LAN sockets. These allow the phone docked with the charger to be accessed using the Device Manager application (browser access via the AIWS unit and charger LAN port or WinPDM application via the USB port).

· Rack Charger This is an 6 phone advanced charger.

· Battery Rack Charger This charger can be used to charge up to 6 batteries separate from the handsets.

· IP Office DECT R4 is supported on IP Office systems running IP Office 5.0+ software. This manual is for systems running IP Office Release 7.0 or higher in IP Office standard mode.

· Licenses Each phone subscribed via the DECT R4 systems requires an Avaya IP Endpoint license in the IP Office configuration.

· Configuration Tools The tools and applications for DECT R4 are included as part of the IP Office Manager application installation. This includes the appropriate firmware for operation with the IP Office system.

· Avaya In-Building Wireless Server (AIWS) This unit allows SMS messaging between handsets. It also allows wireless software upgrades and configuration of the handsets (without an AIWS, handsets can only be upgraded and configured when in an advanced charger). For IP Office Release 5 this unit provides directory integration between the IP Office and the DECT R4 system. For IP Office Release 6 directory integration can be done by the master base station but without SMS support. If both SMS and directory integration are required then an AIWS unit must be used.

15-601047 Issue 03a (21 February 2011)IP Office Release 7.0

1.1 Changes in IP Office Release 7.0

The following major changes have been made in the IP Office Release 7.0 support for DECT R4:

· Avaya 3740 and 3749 Telephones These new phones in the 3700 Series are supported along with matching chargers and other accessories. The 3740 and 3749 are both ruggedized phones (IP65). The 3749 is also intrinsically safe for use in hazardous environments.

· IP Office Provisioning The DECT master base station can be installed in 'provisioning' mode. In this mode, once the base station is operational and connected to the IP Office, the bulk of configuration is done by the IP Office.

· The IP Office is able to provide key settings to the base station such as the system SARI code and the authentication code for phone subscription.

· User configuration and subscription control is done through the IP Office. Previously user configuration and subscription was done in parallel through both the IP Office and base station.

· When using provisioning mode, 3700 Series handset are provided with enhanced menus and idle status display driven by the IP Office. This does not include 3701, 3711 and other GAP compatible phones subscribed to the system.

· When to Use IP Office Provisioning IP Office provisioning both simplifies installation and maintenance and provides 3720, 3725, 3740 and 3749 phones with additional IP Office specific features. Therefore it is the recommended installation method for new installations whenever possible.

· Provisioning installation in pre-configured or auto-create modes should be used for all installations with just 3720, 3725, 3740 and 3749 phones.

· Provisioning installation in pre-configured mode should be used for all installations with a mix of 3720, 3725, 3740, 3749 phones and other DECT phones.

· Provisioning installation should not be used for installations with no 3720, 3725, 3740 or 3749 phones.

· Standard and Advanced Base Station Menu Modes

The base station configuration menus contain settings for a wide range of scenarios and interoperation with a number of Avaya telephone systems. This can make installation both highly flexible but also make it seem unnecessarily complicated. The menus can now be used in standard mode, with only key settings visible or advanced mode with all settings visible. Note that compact base stations use standard mode by default.

DECT R4: Changes in IP Office Release 7.0

1.2 Base Stations

DECT R4 supports three base station variants; the BS330, the Compact Base Station and the BS340. They differ in aerial connection and in the number of simultaneous calls supported. During installation, one of the base stations is configured as the master base station for the DECT R4 system. Any other base stations are configured as slave base stations.

Each base station includes a detachable bracket for use in wall mounting of the base station. Each base station requires a LAN access point and is supplied with a 1.2 metre (4 foot) LAN cable.

Each base station can be powered using IEEE 802.3af power over ethernet (PoE 7W Class 2). Alternatively the base station also requires a main power supply outlet socket within 8 metres (26 feet) cable distance and power supply unit.

· BS330 The BS330 has 2 integral internal aerials which cannot be adjusted. The aerials produce a slightly directional pattern of radio coverage. The base station supports up to 8 simultaneous calls.

· Compact Base Station The Compact Base Station is physically the same as the BS330 but only supports 4 simultaneous calls. Up to 5 Compact Base Station units can be included in a system. If used as the master base station, the whole system is limited to 5 base stations. Compact Base Station are only supported if all the other base stations are running firmware version 3.3.11 or later.

· BS340 The BS340 has 2 external aerials. These aerials produce an even pattern of radio coverage. The base station supports up to 8 simultaneous calls. The aerials can be disconnected and replaced by a various other types of

aerials if different radio coverage patterns and range is required. This type of base station in not supported in

North America.

The base stations include a detachable bracket for use for wall mounting or column mounting of the base station. This also allows the base stations to be removed for maintenance.

DECT R4: Base Stations

1.3 Aerials

The following different aerials can be used to replace the aerials on a BS340 base station. These aerials have aerial leads to allow for optimal positioning. Note that this type of base station and therefore optional aerials are not supported in North America.

· Omni-Directional Single Aerial A pair of these aerials can be used to approximately double the base station radio coverage, ie. up to 600 metres (2000 feet) omni-directional coverage.

· Directional Dual Aerial This aerial gives directional coverage up to 750 metres (2500 feet). Only one aerial unit is required for connection to the base station.

· Directional Single Antenna A pair of these aerials can be used to give directional coverage up to 1000 metres (3300 feet). They must be mounted facing the same direction and approximately 1 metre (3 feet) apart. To achieve maximum coverage, the aerial should be mounted between 4 to 8 metres (13 to 26 feet) above area being covered.

DECT R4: Chargers

1.6 AIWS

The AIWS (Avaya In-Built Wireless Server) unit allows SMS messaging between handsets. It also allows wireless software upgrades and configuration of the handsets. Without an AIWS, handsets can only be upgraded and configured when in an advanced charger.

For IP Office Release 5 this unit also provides directory integration between the IP Office and the DECT R4 system. For IP Office Release 6 and higher, directory integration is done by the master base station without requiring an AIWS. However an AIWS is still required for both SMS.

The unit is managed via web browser and requires a fixed IP address.

· Wall mountable.

· Dimensions: 275 x 130 x 60 mm, 550g.

· Supplied with power supply unit and power cords.

2. Site Survey and Planning

We cannot give precise recommendations for a site survey as every site will vary. However a site survey is a prerequisite to installation in all cases. The correct and effective placement of base stations will prevent problems and maximize coverage. Most issues with any DECT system will arise from the number and positioning of the base stations.

The basic aim is to ensure:

· Base station coverage in all areas of expected DECT phone usage.

· Sufficient number of base stations covering each area for the number of expected simultaneous users (up to 8 per

base station) in that area.

· Sufficient overlap between areas of base station coverage to allow for call handover when DECT phone users are moving.

· Where possible, synchronization of each base station with more than one other base station.

The diagram below indicates the basic measures for coverage between a base station and a DECT phone.

Signal Strength

Description

-40dB

Strong signal typically seen when a phone is close to the base station.

-62dB

Minimum signal strength at which a base station will accept a phone wanting to handover from another base station.

-68dB

Signal strength below which the phone will begin looking for a base station to which it can handover.

-75dB

At this signal strength, the increase error rate will become apparent in the speech.

-90dB

At this signal strength calls are likely to disconnect.

Though this section focuses mainly on the measure of signal strength, the DECT signalling employs a number of methods to overcome a poor signal. The other key factor that affects signalling is the error rate. While decreasing signal strength and increasing error rate are usually related, there may be some scenarios where a high than expect error rate occurs.

Site Survey and Planning: Factors to Consider

2.1 Factors to Consider

Given ideal open field conditions, the range between a phone and a standard base station can be up to 600 metres (2000 feet). However where obstacles absorb signal strength and reflected signals giving increased error rates, the range is more realistically between 30 metres (100 feet) indoors and 300 metres (1000 feet) outdoors.

In practice, no rules or guarantees can be given for base station coverage. Coverage is affected by too many factors that are unique to each site. The following is a guide to those factors that can affect coverage which you should consider and look for during any site survey.

· Obvious causes of signals problems

· Metal surfaces.

· Concrete thickness greater than 1 metre (3 feet).

· Also beware of

· Windows with Reflective Film or Specialized Glass.

These produce increased signal reflection and reduced signal pass-through.

· Wire Meshes and Grills with Apertures of Less than 4cm (1.5 inches). These block signals as effectively as continuous metal sheet.

· Fire Doors These block the signals. In multi-occupancy building such as hotels, the high number of fire-doors may be a problem.

· Stair Wells In modern office buildings, stair wells frequently combine concrete building supports, fire doors and the intervening floor material, making them a special problem.

· Screened Rooms Typically found in offices involved with TV, video and radio production, but also possible in computer centers.

· Empty Sites Do not perform a survey on a site that is not yet occupied. The survey results will differ from those of the same site once occupied by the customer business. Similarly the survey should be performed during normal business hours in order to assess the areas of usage and the effect of equipment being operated and moved.

· Be aware of

· Signal Direction

The signal from a base station does not propagate evenly in all directions. The signal typically propagates strongest in the horizontal plane. However the ability for a base station to serve callers located on floors above or below it should not be ignored. This may allow coverage to be extended to areas not frequently used and so not meriting a dedicated local base station.

· Other Radio Signals

The ability to receive normal broadcast radio signals in an area is not an indication that DECT signaling will be received and vice versa.

· Rack Chargers A rack charger (6 phones) immediately creates an area where a single base station (8 calls) would be near maximum capacity. Look to provide overlapping base station support to areas where rack chargers will be located.

2.2 Handover

Once a phone is connected on a call through a particular base station, it will normally maintain connection with that base station even if the phone moves into an area with a stronger signal from another base station. However, when the signal to the phone drops below -68dB, the phone will begin looking for another base station with a better signal to which it can handover (this is often referred to as "roaming"). If the other base station signal is -62dB or higher, the phone will handover to that base station if it has free capacity.

Site Survey and Planning: Handover

2.3 Base Station Synchronization

Base stations in the DECT R4 system need to be synchronized with each other. This can be done with a signal as low as 90dB between base stations.

One base station is assigned as the 'air synch master', typically the master base station. Each other base station can synch directly with it or indirectly via a synchronization chain. However, it is preferable that the number of synchronization 'hops' between any particular base station and its air synch master base station is kept as low as possible. To help achieve this it is recommended that the air synch master is placed centrally within the set of base stations.

Where possible, each base station should be placed in synchronization range of more than one base station. That allows the base stations to maintain synchronization should one base station fail or be switched off for maintenance. The process of synchronizing by the shortest route to the air synch master when in synchronization range of multiple base stations is automatic.

Advanced Scenario: Separated Locations

In most scenarios, the master base station is used as the air synch master for all the other base stations and that is the scenario documented in this manual. However, in scenarios where you have base stations in separate locations that are not within synchronization range of each other, it is permissible to assign separate air synch masters in each location. However there must be absolutely no overlap (<-90dB) between the separate groups of base stations. Any overlap will cause frequent lose of synchronization.

2.4 Performing a Survey

· While performing a survey you will require the following information:

· Building Layout

Accurate building plans are an essential aid to both the site survey and also for later fault analysis. Ensure that you have an accurate plan of the customer premises, including the locations of mains power outlets and network connection points.

· The area of coverage required? Which areas within the plans the customer expects to be covered. Do they expect coverage outside the building and or in buildings separate from the main building.

· The number of simultaneous users within different areas? Each base station can support up to 8 simultaneous calls (4 for a Compact Base Station).

· Perform the survey during normal business hours. The movement of large items of machinery, such as lifts and shutter doors, will then be observable during the survey.

· Ensure that you have read this documentation and understand the requirement of both phone handover and

base station synchronization .

· As the survey takes place, note whether additional network connection points will be required and or mains power outlets. Consider the use of Power over Ethernet, if possible in order to simplify base station installation.

3.1 DECT Software

Before beginning installation, in addition to having IP Office Manager installed, you need to unpack the DECT R4 software onto your programming PC.

DECT R4 is supported on a range of Avaya systems. However, for IP Office operation, only firmware specifically documented as having been tested and supported with IP Office should be used. Details of supported firmware will be included in IP Office Technical Bulletins and Technical Tips.

On the programming PC, create a folder with a name indicating its purpose, for example c:\IP_DECT_R4.

Within the IP Office Administrator Application software (ie. the software from which IP Office Manager is installed), locate the folder IPDECT.

The folder contains a file DECT R4.zip. This is the file containing software for DECT R4. The file IPDECT.zip contains software for the previously supported IP DECT product and not for DECT R4.

Copy the DECT R4.zip file to the folder created on the programming PC.

Using WinZip or a similar tool, extract the contents of the zip file into the folder, maintaining the directory structure of the zip files.

The set of files should appear similar to the following.

Open the IP Base Station folder and note the software level shown as part of the .bin file filenames. All the base station in the installed system should be run the same levels of software.

Open the Handsets folder and note the software level shown as part of the .pkg file filenames. The handsets in the system should be running this level of software or higher.

Device Management

During installation (provision or non-provisioned) it may be necessary to upgrade the software being used by the 3720, 3725, 3740 or 3749 phones. This is done in one of two ways:

· Windows Device Manager The Windows device manager application can be used to upgrade the software of phones placed in an advanced charger and connected to the PC via USB or LAN. If using this method, install the Windows Device Manager software and load the parameter definition files supplied with the DECT R4 software.

· AIWS Device Management The AIWS device includes an integrated version of device manager that can be used to perform over the air upgrades. This method is only recommended for the maintenance of an existing system. For upgrades during installation of a new system, the use of Windows Device Manager is recommended.
