Use the tools found under the Maintenance button on the first page of the Unified Manager to perform these functions: Time synch, Firmware upload, Backup/Restore/Scheduling, Restore default, and viewing the current Companding law setting.

DECT Installation and Maintenance Guide

22 Chapter 1 DECT system overview and requirements

DECT base station deployment planning

The DECT base stations must be deployed to provide full site coverage with the maximum traffic capacity, using the minimum number of base stations.

There are two tasks involved in arranging this:

•Surveying the site: the site survey involves gathering information to determine customer requirements and the number of cells needed to support the traffic.

•Planning deployment: deployment plans establish the best locations for the radio base stations.

Site surveying and deployment planning are complex tasks, undertaken only by trained personnel. Refer to the M6261DECT Deployment Tool and site planning guide for detailed Site planning and deployment.

DECT radio base station

The Business Communications Manager can support one DECT media bay module.

The information in this section includes:

•“External antennas” on page 23

•“Specifications for DECT radio base stations” on page 25

•“Base station notes:” on page 26

•“Description of the connection” on page 26

A cable attached to an RJ45 connector in the face of the DECT module connects to the base station RJ45 connector. This supplies the data and power.

The base station comes with two internal antennas to provide signal diversity. Some types of external antennas can be substituted, depending on site requirements.

The following table describes the function of the parts of the base station.

Table 2 Parts of the DECT radio base station configurations

Part	Description of function
Base stations	The area covered by the base station depends on the radio range. Base stations
	manage the links with the cordless handsets within that range.
Cables	The cable includes two telephone pairs.
	One transmits the signal.
	One receives the signal.
Connectors	The base station uses a female RJ45 to connect to the cable.

P0606013 02

•The MA431X23 is omnidirectional with an extension cord.

•The MA431X24 is omnidirectional with an extension cord.

•The MA821X12 is bidirectional with a 50-cm cable.

The HT6176A is an adapter for outdoor antennas.

Warning: Do not add any longer cables to the MA821X12, or the gain and receptivity will suffer. Place this antenna as close to the base station as possible.

DECT Installation and Maintenance Guide

24 Chapter 1 DECT system overview and requirements

The MA431X23 and X24 antennas can be installed further from the base station. Ensure that the coaxial cables linking the antennas with the base stations provide low attenuation. The following figure illustrates two configurations:

Figure 4 Antenna configurations

•The internal antenna incorporates an MMS connector (1), one coaxial cable KX21 (2) and the radiating element (3). The antenna gain is 2 dBi.

•The external antenna is connected via a cord (4-5-6) which incorporates an MMS male connector (4), coaxial cable KX21 (5) and a TNC female connector (6). The manufacturer specifies losses of less than the guaranteed dB value. Losses are actually of the order of 0.7 dB at 2 GHz.

The extension cord conveying the signal to the antenna incorporates a TNC male connector (7), low loss coaxial RG58cu cable (8) and N male connector (9). The antenna (11) is secured to the extension cord using N female connector (10).

The losses generated by this extension cord are summarized in the following table.

Table 3 Generated losses with extension cord added

Element	Losses at Frequency	Estimated losses
RG58cu	0.65dB/m at 2GHz
TNC	0.2 dB at 9GHz	0.1 dB
N	0.15 dB at 10GHz	0.1 dB

•The maximum length of the extension cord is 2.8 meters.

•The MA432X23 external antenna with an extension cord performs approximately in the same way as an internal antenna, except for the polarization diversity.

•The MA432X24 provides a 2 dB gain compared to the internal antenna.

Base station notes:

Here are some general-information notes about the base station:

•Do not install more than two overlapping radio base stations per cell.

•Do not apply any paint or other wall covering to the plastic shell without written approval from Nortel Networks.

•Use the Unified Manager to perform resets of the base station.

•Signal processing functions for the four-channel radio base station are ported to the media bay module. In this case, the interface transports four 32 Kb/s ADPCM coded communications as well as 16 Kb/s signaling channel.

Climatic conditions

The DECT base station can tolerate the following conditions:

Operational:

•	Temperature:	5 to 45 degrees C.
		- 20 to +60 with a special cabinet
•	Relative humidity:	10 to 80%, not condensing.
Storage:
•	Temperature range:	- 10 to 60 degrees C.

•Relative humidity range: 10 to 90%, not condensing.

Power supply

The ISDN interface in the DECT media bay module enables the base stations to be powered through the cable connection between the DECT and the base station. The remote power supply is limited to 100 mA on the DECT interface, which corresponds to an available power of 4 W at 48V.

The radio base station can also be powered using a local a.c./d.c. mains power supply unit, PN 840 B. Use a local supply unit for no more than two radio base stations in any given cell.

Description of the connection

DECT base stations connect to DECT media bay modules using a cable containing two twisted pairs. This cable connects to RJ45 connectors on the components. The connection at the DECT position corresponds to an equipment number on the two cards on the DECT module that control the base station interaction. If you assign specific base stations to equipment numbers, you must ensure that base station is connected to the appropriate RJ45 jack on the DECT module.

DECT cordless handsets

Check for small metal objects in the DECT Handset earpiece/mouthpiece before using the handset.

Do not store or locate flammable liquids, gases, or explosive materials in the same compartment or vicinity as the cordless handset, its parts or accessories.

This section describes the features provided by the C4010 and C4020 cordless handsets. These handsets were developed to work with DECT systems.

Other cordless handsets can be used with the DECT system. The system features available to other handsets depends on how the handset is configured, and how compatible it is with the signals transmitted from the DECT module. As well, some features such as call display also require the proper line configurations at both the local and telco end of the line.

Site configurations

Nortel Networks provides one PARI number on the DECT module that all the base stations share. Access is authorized by matching the PARI number and the PARK number registered in the Other multi-site configurations.

DECT call paths

The DECT module provides a telephony path separate from the Business Communication Manager system. This means there are three possible paths for a call to take.

•A DECT handset-to-handset call is routed from the calling handset, through the DECT module C8 interface, into the receiving handset.

•A DECT handset-to-Business Communications Manager set call is routed from the calling handset, into the C8 interface, and into the Business Communications Manager. The Business Communications Manager then routes the call through the appropriate station module to the receiving set.

•A DECT handset-to-external call is routed from the calling handset, into the C8 interface, and into the Business Communications Manager. The Business Communications Manager then routes the call through the appropriate trunk module out to the public network. This is the same route a call from a DECT handset to a set on a private network would use. The difference is that the user enters a different destination code.

•If a DECT handset transfers a call, the DECT C8 processes the transfer and creates a new call destination. The call remains routed through the C8 interface, even though the DECT handset is no longer involved in the call.

DECT programming overview

Here are some important points about using DECT on your Business Communications Manager.

•The Business Communications Manager must be configured with a region setting that provides DECT support.

Note: Valid DECT region settings:

Australia, Denmark, France, Germany, Global, Holland, Italy, Norway, Spain, Sweden,

Switzerland, Taiwan, United Kingdom

•The system default password is set to insta. You can delete or change this password to suit your needs.

•Default language is English.

•Disable the base stations before a firmware upgrade. Put the base stations back in service in sequence.

•To subscribe handsets, a base station must be set to accept handset recording.

•The handset DN must also be set into recording mode before the handset can be subscribed.

•The system uses data links.

•Within the DECT interface, numbers enclosed in ( ) indicate length of parameters. Refer also to “DECT interface commands” on page 28 and “Numbering plan syntax” on page 29.

Note: Refer to the Business Communications Manager Programming Operations Guide to configure telephony parameters for each handset DN.

DECT interface commands

The following table shows the main commands that are needed to navigate the DECT interface.

Table 4 DECT interface commands

Command	Explanation
Ctrl U	Goes to main menu.
Ctrl J	Moves up one level of menus.
space bar	Toggles between items within screens.
Esc (alpha commands)	ESC M = more
	A list displays at the bottom of each screen.
Del	Deletes item backwards.

Numbering plan syntax

The following table explains how the syntax for the numbering plan works:

Table 5 Numbering plan syntax

Number Plan width	Entry	Means
(2)	1-2	10 to 29
(3)	12-3	120 to 139
(5)	1623-4	16230 to 16249
(5)	1-2	10000 to 29999

Business Communications Manager requirements

The DECT system only works with a Business Communications Manager system that has been set to a compatible region. Region settings determine basic system compatibilities with local telephony protocols. Confirm the region on your Business Communications Manager before you attempt to install the system. Regions are discussed in the Business Communications Manager Programming Operations Guide.

This book describes the handset directory number (DN) system based on the default setup, where the Start DN is 221 and the DN length is three digits. If your system has a different DN structure, use the tables provided to translate the DNs listed to match those of your system.

Examples of DN structures:

If your Start DN is 221 but you require a five-digit DN, the system automatically creates a Start DN of 22221 when you specify a five-digit DN at startup.

If your Start DN needs to start with a specific number, change the Start DN after you specify the DN length at startup. For instance, if your Business Communications Manager is part of a CDP (Coordinated Dialing Plan) network with five-digit DNs, your system must have a unique first DN digit, so you would specify the exact Start DN, in this case, something like 31111.

Checking the System Region

If you experience problems configuring the DECT module on your system, check the region for which the system is set.

Note: DECT systems can be installed in countries that can run the following region profiles: UK, Australia, Sweden, Denmark, Holland, Norway, Italy, Germany, Spain, Switzerland, France, Global, Taiwan.

Refer to the Business Communications Manager Programming Operations Guide appendices for the table that lists all the regions.

Caution: You must select a region that reflects the geographical location of the Business Communications Manager.

If you choose the incorrect region, the Business Communications Manager system does not communicate correctly with the Public Switched Telephone Network.

This procedure describes how to ensure that the Business Communications Manager is set to the correct region for the DECT module.

1Open the Unified Manager for your Business Communications Manager system.

2On the navigation tree, click Diagnostics/MSC.

3On the top menu, click on Configuration.

4Click System startup.

5Ensure that the Region box displays the correct region.

Warning: If you reset the region profile on the Business Communications Manager, the system is reset to default parameters. Therefore, ensure that you have a current backup before you attempt to do this procedure.

Note: When you select a new region, the Template box is disabled. You must restart the system before the templates for the selected region are available.

aTo change the region, select a region from the list.

bClick OK to apply these changes.

The system displays a warning that the system will restart and that the default programming values will be restored.

cClick Cold Start to restart the Unified Manager.
