Safety
This equipment meets all applicable requirements of both the CSA C22.2 No.60950 and UL
60950.
The shock hazard symbol within an equilateral triangle is intended to alert personnel
to electrical shock hazard or equipment damage. The following precautions should
also be observed when installing telephone equipment.
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed
for wet locations.
• Never touch uninsulated telephone wires or terminals unless the telephone line has
been disconnected at the network interface.
• Use caution when working with telephone lines.
Danger: Risk of shock.
Read and follow installation instructions carefully.
Ensure the system and system expansion units are unplugged from the power socket and
that any telephone or network cables are unplugged before opening the system or system
expansion unit.
If installation of additional hardware and /or servicing is required, disconnect all telephone
cable connections prior to unplugging the system equipment.
Ensure the system and system expansion units are plugged into the wall socket using a
three-prong power cable before any telephone cables are connected.
N0000623 01
Caution: Only qualified persons should service the system.
The installation and service of this hardware is to be performed only by service personnel
having appropriate training and experience necessary to be aware of hazards to which they
are exposed in performing a task and of measures to minimize the danger to themselves or
other persons.
Electrical shock hazards from the telecommunication network and AC mains are possible
with this equipment. To minimize risk to service personnel and users, the system must be
connected to an outlet with a third-wire ground. Service personnel must be alert to the
possibility of high leakage currents becoming available on metal system surfaces during
power line fault events near network lines. These leakage currents normally safely flow to
Protective Earth ground via the power cord. Therefore, it is mandatory that connection to
an earthed outlet is performed first and removed last when cabling to the unit. Specifically,
operations requiring the unit to be powered down must have the network connections
(central office lines) removed first.

Radio-frequency Interference
Warning: Equipment generates RF energy.
This equipment generates, uses, and can radiate radio-frequency energy. If not installed
and used in accordance with the installation manual, it may cause interference to radio
communications. It has been tested and found to comply with the limits for a Class A
computing device pursuant to Part 15 of the FCC Rules and with ICES.003, CLASS A
Canadian EMI Requirements. Operation of this equipment in a residential area is not
permitted and is likely to cause interference.
Repairs to certified equipment should be made by an authorized maintenance facility designated
by the supplier. Any repairs or alterations made by the user to this equipment, or equipment
malfunctions, may give the telecommunications company cause to request the user to disconnect
the equipment. Users should ensure for their own protection that the electrical ground connections
of the power utility, telephone lines and internal metallic water pipe system, if present, are
connected together. This precaution may be particularly important in rural areas.
Caution: Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or electrician.

• Digital Mobility Service Tool: the tool you access from your computer and use to configure
and manage handsets and repeaters.
The DMC OAM application and Digital Mobility Service Tool are separate from the host system
configuration tool.
21
Before you begin
This guide assumes the following:
• you are using one of the following host systems:
• Norstar MICS 7.0 or greater (Modular Integrated Communications System)
• Norstar CICS 7.0 or greater (Compact Integrated Communications System)
• BCM 3.7 or greater (Business Communications Manager)
• that users have a working knowledge of the host system operations.
• that all configuration installers have a working knowledge of the Windows operating system
and graphical user interfaces.
• that a site survey has been conducted and the installer has access to these plans.
• the host system is installed and initialized and is working correctly.
DECT and DECT variants
The DMC uses Digital Enhanced Cordless Telephony (DECT), which is a digital wireless
technology that has been standardized by the ETSI (European Telecommunications Standard
Institute). Although a European standard, the technology has spread worldwide with only minor
differences to the frequency band allocated for wireless telephony in different markets. Besides
DECT there are four additional variants which in this guide is described as:
• 2G4: The North American DECT variant operating in the 2.4 GHz frequency band.
• SAM: The South American DECT variant operating in the 1900 - 1930 MHz frequency band.
• China: Chinese DECT variant operating in operating in the 1900 - 1920 MHz frequency band.
Digital Mobility System Installation and Configuration Guide
22 Preface
• Ta iw an : Taiwanese DECT variant operating in operating in the 1880 - 1885 MHz frequency
band.
For a complete overview of the countries and their accepted DECT variant, see table below:
Table 1 Countries and DECT variants
N0000623 01
Preface 23
Note: The above table may be subject to changes. To see an updated list, see the DECT Industry
Association web site: www.dect.ch where a global presence map is available and regularly
updated.
DMC GAP compliance
The DMC is fully GAP compliant as per ETSI standards. Being GAP compliant, the DMC
supports GAP compatible product as described in the GAP standard. The GAP compliance only
secures basic telephony between GAP compatible products from different manufactures. In order
to ensure handover between base stations and full functionality on the handset, it is strongly
recommended to use only Nortel Network handsets with the DMC and radio infrastructure.
The handsets being supported for basic telephony are the following:
• M DECT C4012 DECT handset
• M DECT C4030 DECT handset
• M DECT C4050 DECT handset
The handsets being supported for full functionality are the following
• Digital Mobility Phone 7420 (only for use in North America)
• Digital Mobility Phone 743X
• Digital Mobility Phone 744X
• Digital Mobility Phone 745X
Handset GAP compatibility
The Nortel Networks handsets are GAP compliant as per the ETSI GAP standard. The GAP
compliance does not secure the compatibility of third part handsets on the Nortel Networks
system. Likewise, the Nortel Networks handsets cannot be guaranteed to be fully supported on
other wireless systems. Therefore, it is recommended only to use Nortel Networks handset with
the Nortel Networks wireless system.

Digital Mobility Controller (DMC)
The Digital Mobility Controller is the mobility subsystem component which connects to the Nortel
Networks host system. The DMC together with the host system handles the routing of telephone
calls between the base stations and the host system.
The DMC is available in two versions:
• DMC080 - supporting up to two base stations and eight TCM loops for support of eight
handsets.
• DMC320 - supporting up to eight base stations and 32 TCM loops for support of 32 handsets.
It is possible to link two systems together to make a number of different host system-DMC
configurations:
N0000623 01
Chapter 1 Overview 29
Table 2 Host system - DMC configurations
See “Digital Mobility system diagram” on page 27 for an illustration of the Primary - Secondary
configuration.
Digital Mobility Base station (RFP)
The base stations are positioned in the area to send and receive calls between the host system and
the handset. The base station contains internal antennas and handles four speech channels
simultaneously. A base station is able to synchronize with other base stations. When the base
station is synchronized with other base stations, a person speaking in a handset can move between
base stations without any interference.
Note: Whether the base station is connected to the Primary or Secondary DMC is of no
importance to the synchronization as a base station is synchronized automatically when
performing cable delay measurement. Refer to “Connecting DMC to host system (TCM loop)” on
page 63 for more information on cable delay measurement.
Transmission length is up to 1.5 km on a twisted standard pair category 4 cable, between the base
station and the DMC. From this connection the base station is supplied with power from the DMC
(max. supply 1.5 W). The radius coverage of the base station is 600 meters with a Digital Mobility
handset in free sight.
Coverage area decreases depending on choice of building materials and obstructive elements. To
ensure proper coverage in the areas required, it is necessary to conduct a site survey and
deployment by certified technicians.
Digital Mobility System Installation and Configuration Guide
30 Chapter 1 Overview
The host system supports the following wireless base stations:
• Digital Mobility Base station 10 (2.4 GHz frequency band)
• Digital Mobility Base station 12 (1900 - 1920 MHz frequency band)
• Digital Mobility Base station 13 (1880 - 1885 MHz frequency band)
• Digital Mobility Base station 14 (1900 - 1930 MHz frequency band)
• Digital Mobility Base station 15 (DECT)
Refer to “Base station installation” on page 65.
Digital Mobility Repeater (WRFP)
The repeater is available as a half slot or full slot repeater. A half slot repeater covers two
simultaneous speech channels; a full slot repeater covers four simultaneous speech channels.
These channels are borrowed from the attached base stations, and are not additional channels to
the system total number of channels. A full slot repeater increases the coverage area. A half slot
repeater also increases the coverage area but with reduced capacity.
Note: The repeater does not increase the traffic capacity. Instead, it increases the radio coverage
area of the system by a maximum of 50 per cent.
The repeater has two internal antennas which are used for increasing the effective range of a base
station in a certain direction. The repeater is also available with a connector for a third external
antenna (directional antenna) which can be used to create a new coverage cell up to 1000 meters
away from the base station.
Figure 2 Repeater with external antenna
N0000623 01
Chapter 1 Overview 31
The digital repeater relays the radio signals between the handsets and the base station, making it a
wireless component from the DMC.
Note: The repeater is powered with a 9.0VDC - 300mA transformer. Therefore, it needs a power
source within three meters.
The host system supports the following wireless repeaters:
• Digital Mobility Repeater 20 (2.4 GHz frequency band)
• Digital Mobility Repeater 22 (1900 - 1920 MHz frequency band)
• Digital Mobility Repeater 23 (1880 - 1885 MHz frequency band)
• Digital Mobility Repeater 24 (1900 - 1930 MHz frequency band)
• Digital Mobility Repeater 25 (1880 - 1900 MHz frequency band) (DECT)
Refer to “Repeater installation” on page 71.
Digital Mobility Phone (PP)
The host system supports the following wireless handsets:
• Digital Mobility Phone 7420 (only for use in North America)
• Digital Mobility Phone 743X
• Digital Mobility Phone 744X
• Digital Mobility Phone 745X
where X represents the frequency variant of the models:
• 0 = (2.4 GHz frequency band)
• 2 = (1900 - 1920 MHz frequency band)
• 3 = (1880 - 1885 MHz frequency band)
• 4 = (1900 - 1930 MHz frequency band)
• 5 = (1880 - 1900 MHz frequency band) (DECT)
Refer to “Preparing handset for use” on page 83.
Refer to “DECT and DECT variants” on page 21 for more information about DECT and frequency
variants.
The handsets used with the DMC are uniquely designed as small, lightweight units with an
extensive feature list. Refer to “Host system and handset interoperability” on page 111.
All handsets have a display. The displays has a three-line capacity. Each line is 16 alphanumeric
characters wide. There are also five functional icons that may appear on the display. These features
are described in the Digital Mobility Phone User Guide.

Positioning a base station
Avoid installing base stations on large concrete or marble columns because these columns affect
radio coverage. If possible, place the base station a minimum of one meter from these types of
columns. Do not install a base station with the antenna housings near metal objects. Be careful not
to damage existing wiring or panels.
Do not position base stations in ducts, plenums, or hollow spaces used to transport environmental
air except where the duct, plenum or hollow space is created by a suspended ceiling having lay-in
panels.
To expand a coverage area with base stations, additional base stations must be placed in such a
way that overlap between the base stations radio coverage is established. It is recommended that
the overlap is at least 10 to 15 meters.
Note: Radio coverage depends on material and construction of buildings and surroundings.
Warning: Never install base stations in rows.
