Provisioning the T7406 / 7
Provisioning the T7406
This chapter provides specification and provisioning information for
the T7406 cordless system.
The T7406 is a Frequency Hopping Spread Spectrum (FHSS) cordless
telephone. The benefits of this technology are: improved range,
robustness and, less susc eptibility to in terference, fading and mult ipath.
The use of a common wall-mounted base station for multiple handsets
allows you to position t he base antenna s for maximum performa nce and
coverage. The indoor range of the T7406 is 95 meters (300 feet) in a
typical office environment. This range may vary with differing
environments.
Operational Bandwidths
The T7406 cordless telephone operates in the ISM (Industrial,
Scientific, and Medical) 902-928 MHz band. The T7406 divides the
ISM band into two sets of operating frequencies to allow the
coexistence of othe r ISM devic es . Examples o f these produc ts are SKU
scanners and remote controls for products such as garage door openers
and home theatre systems. Note that, since the T7406 is a frequency
hopper, it uses at lea st hal f of t he avai lable frequ enc ies in the ISM ba nd
for operation and can make it difficult for other 900 MHz devices to
operate correctly. The following table identifies the frequencies used
for the upper and lower bands of operation:
• Lower: 902 - 915 MHz
• Upper: 915.1 - 928 MHz
These bands are selectable for each base station through dip switches
located on the back of the T7406 base station. Each base station
supports up to three handsets. Selection of the correct band for
operation may minimize interference between devices.
Operational Parameters
For example, with a con figur ation of si x handse ts, t wo ba se sta tions ar e
required (three hands ets per base s tation). One ba se station will be set to
the upper band, and the other base station will be set to the lower band.
T7406 Installation Guide
8 / Provisioning the T7406
Another example is an environment that already contains another 900
Mhz device (e.g. a scanner with 900 Mhz wireless connection to a
LAN). In this environment, only one T7406 base station should be
installed. Set the T7406 base station dip switch to the opposite band
that the scanner is operating in.
Installation Site Parameters
Physical characteristics of the site where the T7406 is to be installed, or
has been installed, must be evaluated to maximize the performance of
the T7406 telephone. Outlined below are some of the most common
characteristics to be considered:
• wood vs. metal construction
• metal vs. wood studs in wall construction
• thickness of concrete floors and walls (and type of covering, e.g.
Metallic wall paper)
• number of floors and walls
• open office (cubicles) vs. closed office (floor to ceiling)
• steel partitions, elevator shafts, electric utility rooms
• RF LANs (Radio Frequency Local Area Networks), extensive
machinery, computer equipment, and other cordless phones or
wireless devices
Placement of the antenna is crucial for enhancing the performance of
the T7406. Pick a central location and mount the antenna with the
following guidelines:
• Attach the base station at least 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 90degree angle planes (i.e. perpendicular to the wall, parallel to the
wall, perpendicular to the floor, parallel to the floor)
P0606142 01
Provisioning the T7406 / 9
RF LANs (Radio Frequency Local Area Networks)
RF LANs 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 T7406 operating band, the RF LAN
operating at 900 MHz does not pose an operating issue for T7406 nor
does the T7406 pose issues for the RF LAN with respect to data
transmission capabilities. However, there may be instances where the
T7406 user may hear an occasi onal sli ght audio c lick when op erating in
a RF LAN environment. This should not inhibit the user's ability to
hold a normal two-way conversation using the T7406.
Telephone-to-Base Range
The T7406 cordless telephone utilizes an extremely efficient radio
design to deliver the maximum possible range while complying with
the governing rules of the Federal Communicat ions Commission (FCC)
and Industry Canada. The effective operating range within a site will
largely depend on the environmental characteristics mentioned
previously, such as build ing cons truc tion a nd int ernal la yout of the s ite.
Typically, the T7406 will provide an effective operating range of 95
meters (300 feet).
If the T7406 is not meeting t his opera ting ran ge, the fol lowing ar e some
steps that can be taken to assist with the troubleshooting:
• Check surroundings for any other product that my be causing
interference.
• Check env ironment for obstructions that may be limiting the ra nge.
• Change the orientation of the base station antenna.
• Move the base station to another location.
• Select the alternate operating band of the T7406.
It is impor tant to keep in mind that, based on environmental
characteristics, the T7406 may not be the optimum solution for all
users. If the desired level of mobility performance is not met, contact
your authorized Nortel Networks distributor to discuss alternatives.

Powering the T7406
The T7406 design has taken int o ac count the need to provide a relia bl ypowered cordless business telephone. The T7406 utilizes premium
1400 mAh NiMh batteries.
A fully charged 1400 mAh battery should provide four to five hours of
talk time in a typical eight-hour day over, approximately, a three-year
service life.
The T7406 has been engineered to provide the following talk-time
parameters:
• T7406 users should feel comfortable using the handset for an entire
workday without the need to put the handset back into the charger
cradle for charging or topping up.
• Studies have shown th at users have be en able to get f our to five hours
of talk time from a fully charged 1400 mAh battery.
• Traffic studies have shown that typical users do not usually need
more that three hours of talk time in an eight-hour day.
• If talk times exceed four hours or the product is to see use through
multiple, consecutive shifts, multiple spare batteries are strongly
recommended.
Battery Charge Controller
The T7406 incorporate s a special handset batte ry c har ge controller that
employs a four-stage charging program that seque nce s charging from a
soft start to a fast charge, and then to a topping charge, followed by a
maintenance charge.
This four-stage charge sequence presents an optimum-charging plan
that helps maximize the overall life of the battery by managing two
critical elements in the battery charging process, the charge rate and
overcharging protection. Note that NiMh batteries do not exhibit
memory problems and it is not necessary to drain the batteries prior to
recharging.
Low battery status is indicated on the handset by the visual charge
status on the display and/or the audible warning tone.
The T7406 handset can be placed back into the charge cradle for
charging when it is not in use.

16 / About your T7406 telephone
About your T7406 telephone
The T7406 is a multiple-handset, single-base cordless telephone
system. The T7406 telephone provides a full y-integrated mobility
solution for your business. The T7406 handset allows you to freely
move around your work space while on a call, and still maintain access
to all your telephone system features.
The T7406 telephone uses advanced digital frequency hopping spread
spectrum (FHSS) techn ology t o provi de a qu alit y audio path o ver a 900
MHz radio link. Establishing a call over a radio link is comparable to a
wire line c ommunicatio n.
Note: The T7406 cordless telephone is supported on all Norst ar systems
(DR3 or higher) and on all Business Communications Manager
systems.
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. Typically, a
dense office or warehouse envi ronment has an ef fective operating ra dio
range of 95 meters (300 feet). An open office environment enhances
operating radio ranges. Refer to Provisioning the T7406
on page 7.
Security of Conversation
Each base station has a unique Security Code (S.S. Code). All three
handsets registered t o the base station must sha re the same Security
Code. Each of the three handsets assigned to a base station must also
have a unique identification (Set I.D. 1, 2 or 3).
Density and Interference
For this system to be interference-free, install a maximum of two base
stations and six handsets per location. Each base station provides three
independent time c ompre ss ion multiplexing (TCM) lin e c onnections to
the telephone system.
Each base station uses half of the Industrial Scientific Medical (ISM)
band for its frequency hopping channels. The dip switches on the base
station allow you to assign the base station to use either the lower half
(902-915 Mhz) or the upper half (915.1-928 Mhz).
P0606142 01
About your T7406 telephone / 17
Each base station must use a separate ISM half band. For more
information about setting the dip swi tches, refer to Installing the Base
Station on page 21.
If other devices operating on the ISM band interfere with the T7406
base, the other half of the band may be used to try to minimize
interference. In this situation, install only one base station and three
handsets per location.
Spare Parts
You can order spare parts for your T7406 telephone. For more

Installing the Base Station
This section describes the base station and:
• how to mount the base station on a wall
• what programming is re quired before you connect t he base statio n to
your system
• how to connect the base station to your system
The T7406 cordless telephone operates on the same principle as a twoway radio. Therefore, the location of the base station affects the range
of reception. The base stati on should not be ins talled where radio waves
are blocked or reflected, such as next to a filing cabinet.
For optimal performance, install the base station at least 2.4 meters
(eight feet) above the floor and at least 3.2 meters (ten and one half
feet) apart from a second b ase sta ti on. Al ways position the antenna at a
90° angle to the base station.
Base Station Features
This section illustrates the base station for the T7406 system.

Handset Configuration
This section describes how to set up handsets on a base station. Note
that there is one extra step for setti ng up the firs t handset on a new base
station.
Important First-time Installation Information
When performing the initial configurations on the handset, ensure that
all the handsets you intend to configure have fully-charged battery
packs installed.
Since the handsets start s canning as soon a s they ar e powered, yo u must
set the handset ID #s first when you configure the handset to avoid
conflicts between handset signals and the possibility of one set
mirroring another.
T7406 Installation Guide
28 / Handset Configuration
If you install more than one base station on a system, ensure that you
assign a unique Security code to each base station. However, all base
stations have the same three Handset ID numbers (1, 2, or 3), which
identify th e handset to t he base station.
Identifying the Handsets to the System
Each of the three handsets registered to a base station share an identical
Security code, but each handset has a unique handset ID number of 1, 2,
or 3.
The handset ID number the handset is assigned to maps back to the
TCM/RJ-11 jack on the back of the base station. The diagram below
identifies which jack supports which handset ID number.
Handset ID 1 Handset ID 2 Handset ID 3
23
1
In turn, these numbers correspond to telephone records in the main
system. In the system, these records identify each telephone with a local
number, referred to as a DN (directory number). Since the records will
be set up before you configure your handset, check with your system
administrator to determine which local has been assigned to which port.
From there, you can identify which Handset ID number should be
assigned to each handset.
Note: When a base station i s reloca ted, the Handset ID numbe r follows
the set DN (system telephon e record), if the Set rel ocation feature
is on.
P0606142 01
Handset Configuration / 29
Assigning the Handset to the Base Station
When you assign the first handset to a base station, you must send the
security code to the base station. For subsequent handsets, you only
need to identify the security code on the handset itself. This is
explained in detail in later sections.
This is the general process for setting up a T7406 handset:
• Identify the handset to a unique Handset ID # (1, 2, or 3)
Note:The handset ID #, which gets assigned to each handset,
matches up to TCM/RJ-11 jack on the back of the base .
station. Ask your system administrator which handset ID
maps to which set DN on the system.
• Change the default password for selecting a handset ID (default:
000000)
• Assign a Security code (S.S. code)
• Send the Security code from the handset to the base station
Note:Sending the security code to the base station is only
performed for the first handsets. For subsequent handsets,
you need only identify the security code on the handset.
• Assign the ring type
• Assign the ringer volume
• Assign the language that appears on the handset display

handsets, the security code must be identical, but it does not need to be
re-assigned to the base station.
Other sett ings are the same for all handsets.
