Installation considerations
The T7406E is a cordless telephone system that allows you to freely move around your work space
while on a call, and still maintain access to the telephone system features available to you.
The T7406E telephone uses advanced digital FHSS technology to provide a quality audio path
over a 2.4 GHz radio link.
Note: The T7406E cordless telephone is supported on all Norstar systems (DR3
or higher) and on all Business Communications Manager systems.
The use of a wall-mounted base station allows you to position the base antennas for maximum
performance and coverage. The indoor range of the T7406E varies based on the type of office
environment. The outdoor clear-line-of-sight range is 350 meters (1000 feet). This range can vary
with differing environments.
Operational bandwidths
The T7406E cordless telephone operates in the Industrial, Scientific, and Medical (ISM) 2.4 GHz
band.
Radio frequency local area networks
Radio frequency local area networks (RF LAN) are primarily installed in large chain businesses,
such as retail and grocery, where the RF LAN is used for inventory equipment.
With the correct selection of the T7406E operating band, the RF LAN operating at 2.4 GHz does
not pose an operating issue for T7406E, nor does the T7406E pose issues for the RF LAN with
respect to data transmission capabilities. However, there can be instances where the T7406E user
can hear an occasional audio click when operating in an RF LAN environment. This should not
inhibit the user's ability to hold a normal two-way conversation using the T7406E.

Chapter 2 Introduction 15
Operational parameters
For a configuration of eight handsets, you need two base stations. Each base station supports a
maximum of four handsets.
Telephone-to-base range
The T7406E cordless telephone utilizes an extremely efficient radio design to deliver the
maximum possible range while complying with the governing rules of the Federal
Communications Commission (FCC) and Industry Canada. The effective operating range within a
site largely depends on the environmental characteristics, such as building construction and
internal layout of the site. The indoor range of the T7406E varies based on the type of office
environment. The outdoor clear-line-of-sight range is 350 meters (1000 feet). This range can vary
with differing environments.
If the T7406E does not meet this operating range, try the following troubleshooting activities:
• Check surroundings for any other product that can cause interference.
• Check the environment for obstructions that can limit the range.
• Change the orientation of the base station antenna.
• Move the base station to another location.
• Select the alternate operating band of the T7406E.
Based on environmental characteristics, the T7406E may not be the optimum solution for all users.
If the desired level of mobility performance is not met, contact your authorized Nortel distributor
to discuss alternatives.
Radio range and coverage considerations
The effective operating radio range in your facility depends on the building construction and the
internal layout of the facility. An open office environment enhances operating radio ranges.
Density and interference
For this system to be interference-free, install a maximum of two base stations and eight handsets
per location. Each base station provides four independent time-compression multiplexing (TCM)
line connections to the telephone system.
Installation site parameters
To maximize the performance of the T7406E telephone, evaluate the physical characteristics of
the site prior to determining the location of the base station installation. Consider the following
common characteristics:
• wood versus metal construction
• metal versus wood studs in wall construction
• thickness of concrete floors and walls (and type of covering, for example metallic wall paper)
T7406E Cordless Handset Installation and Configuration Guide
16 Chapter 2 Introduction
• number of floors and walls
• open office (cubicles) versus closed office (floor to ceiling)
• steel partitions, elevator shafts, electric utility rooms
• radio frequency local area networks (RFLAN), extensive machinery, computer equipment, and
other cordless phones or wireless devices
Place the antenna correctly to endure that the performance of the T7406E is at its best. Pick a
central location and mount the antenna using the following guidelines:
• In a two-base-station installation, space the base stations a minimum of 10 meters apart, and a
minimum of 10 meters from any other 2.4 GHz wireless equipment.
• Attach the base station a minimum of eight feet from the floor.
• Minimize the number of walls between the base station and handsets.
• Centralize the location of the base station to make the number of interfering walls equal in all
directions.
• Do not mount the base station on an outside wall.
• Do not mount or place the base station outdoors.
• Adjust the antenna for optimal transmission by moving it through 90-degree-angle planes (for
example, perpendicular to the wall, parallel to the wall, perpendicular to the floor, parallel to
the floor).
Environment layout considerations
The following facility layouts are examples of reference building footprints for which the T7406E
is most suited.
Storefronts
This layout has fewer than 929 square meters (10 000 square feet) of floor space. This layout has
open environments with few interior barriers

46 m (150 ft)
The T7406E can also be used in business premises
with larger square footage and that have an interior
layout that has a higher concentration of physical
barriers. Full radio coverage at these facilities takes
more planning to work around possible barriers.
46 m
(150 ft)
A professional office
• is typically less than 2 323 square meters (25 000
square feet) in size
• is typically a mix of open and closed offices
• has an office floor with an elevator shaft and utility
rooms in the core facility
Some transmission path loss occurs when the base station and the handset are separated by
physical barriers, as represented by this core area.
The amount of path loss is depends on the number of walls, type of material, and density of
barriers used in the core area.
Combination office/warehouse
30.5 m
(100 ft)
• Various small businesses
• Typically under 1 394 square meters (15 000 square
feet)
• Mixture of closed offices and open spaces
61 m
(200 ft)
Typical facility with both office and warehousing
combined in one operation.
Some transmission path loss in expected with the
presence of dense firewall and racking or shelves
filled with dense materials. Consider placing base

Office with adjacent yard area(s)
95 m
(300 ft)
Unsuitable environments
Large campuses (business sites with more than one building) are not a suitable application for the
T7406E.
• Various small businesses
• are typical office facilities with 465 to 929 square
meters (5 000 to 10 000 square feet) of floor space
• have adjacent open space or a yard next to office
•radio transmission is relatively unimpaired in more
open environments because there are fewer path
losses caused by barriers, such as walls
This environment can allow for
base-station-to-handset ranges in excess of 95 m
(300 feet).
For this type of environment, contact your authorized Nortel distributor to discuss alternatives.
Handset overview
The T7406E handset automatically links with the base station by searching for the base station
