About Avaya 7406 Digital Mobile Handset
The Avaya 7406 Digital Mobile Handset is a multiple-handset, single-base Digital Mobile
Handset. The Avaya 7406 digital mobile handset provides a fully-integrated mobility solution for
your business. The Avaya 7406 Digital Mobile 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 Avaya 7406 Digital Mobile Handset uses advanced digital frequency hopping spread
spectrum (FHSS) technology to provide a quality audio path over a 900 MHz radio link.
Establishing a call over a radio link is comparable to a wire line communication.
Note: The Avaya 7406 Digital Mobile Handset is supported on all Avaya Norstar
systems (DR3 or higher) and on all Avaya 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 environment has an effective
operating radio range of 95 meters (300 feet). An open office environment enhances operating
radio ranges. Refer to
Security of Conversation
Each base station has a unique Security Code (S.S. Code). All three handsets registered to the base
station must share 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 compression multiplexing (TCM) line
connections 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).
Each base station must use a separate ISM half band. For more information about setting the dip
switches, refer to
If other devices operating on the ISM band interfere with the Avaya 7406 Digital Mobile Handset
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.
