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)
