T7406 Cordless Telephone Installation Guide

Provisioning the T7406 / 9RF LANs (Radio Frequency Local Area Networks)RF LANs are primarily installed in large chain businesses such as retailand grocery where the RF LAN is used for inventory equipment.With the correct selection of the T7406 operating band, the RF LANoperating at 900 MHz does not pose an operating issue for T7406 nordoes the T7406 pose issues for the RF LAN with respect to datatransmission capabilities. However, there may be instances where theT7406 user may hear an occasional slight audio click when operating ina RF LAN environment. This should not inhibit the user's ability tohold a normal two-way conversation using the T7406.Telephone-to-Base RangeThe T7406 cordless telephone utilizes an extremely efficient radiodesign to deliver the maximum possible range while complying withthe governing rules of the Federal Communications Commission (FCC)and Industry Canada. The effective operating range within a site willlargely depend on the environmental characteristics mentionedpreviously, such as building construction and internal layout of the site.Typically, the T7406 will provide an effective operating range of 95meters (300 feet).If the T7406 is not meeting this operating range, the following are somesteps that can be taken to assist with the troubleshooting: Check surroundings for any other product that my be causinginterference. Check environment for obstructions that may be limiting the range. 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 important to keep in mind that, based on environmentalcharacteristics, the T7406 may not be the optimum solution for allusers. If the desired level of mobility performance is not met, contactyour authorized Nortel Networks distributor to discuss alternatives.T7406 Installation Guide

Provisioning the T7406 / 13Powering the T7406The T7406 design has taken into account the need to provide a reliablypowered cordless business telephone. The T7406 utilizes premium1400 mAh NiMh batteries.A fully charged 1400 mAh battery should provide four to five hours oftalk time in a typical eight-hour day over, approximately, a three-yearservice life.The T7406 has been engineered to provide the following talk-timeparameters: T7406 users should feel comfortable using the handset for an entireworkday without the need to put the handset back into the chargercradle for charging or topping up. Studies have shown that users have been able to get four to five hoursof talk time from a fully charged 1400 mAh battery. Traffic studies have shown that typical users do not usually needmore that three hours of talk time in an eight-hour day. If talk times exceed four hours or the product is to see use throughmultiple, consecutive shifts, multiple spare batteries are stronglyrecommended.Battery Charge ControllerThe T7406 incorporates a special handset battery charge controller thatemploys a four-stage charging program that sequences charging from asoft start to a fast charge, and then to a topping charge, followed by amaintenance charge.This four-stage charge sequence presents an optimum-charging planthat helps maximize the overall life of the battery by managing twocritical elements in the battery charging process, the charge rate andovercharging protection. Note that NiMh batteries do not exhibitmemory problems and it is not necessary to drain the batteries prior torecharging.Low battery status is indicated on the handset by the visual chargestatus on the display and/or the audible warning tone.The T7406 handset can be placed back into the charge cradle forcharging when it is not in use.T7406 Installation Guide

16 / About your T7406 telephoneAbout your T7406 telephoneThe T7406 is a multiple-handset, single-base cordless telephonesystem. The T7406 telephone provides a fully-integrated mobilitysolution for your business. The T7406 handset allows you to freelymove around your work space while on a call, and still maintain accessto all your telephone system features.The T7406 telephone uses advanced digital frequency hopping spreadspectrum (FHSS) technology to provide a quality audio path over a 900MHz radio link. Establishing a call over a radio link is comparable to awire line communication.Note: The T7406 cordless telephone is supported on all Norstar systems(DR3 or higher) and on all Business Communications Managersystems.Radio range and coverage considerationsThe effective operating radio range in your facility depends on thebuilding construction and the internal layout of the facility. Typically, adense office or warehouse environment has an effective operating radiorange of 95 meters (300 feet). An open office environment enhancesoperating radio ranges. Refer to Provisioning the T7406 on page 7.Security of ConversationEach base station has a unique Security Code (S.S. Code). All threehandsets registered to the base station must share the same SecurityCode. Each of the three handsets assigned to a base station must alsohave a unique identification (Set I.D. 1, 2 or 3).Density and InterferenceFor this system to be interference-free, install a maximum of two basestations and six handsets per location. Each base station provides threeindependent time compression multiplexing (TCM) line connections tothe telephone system.Each base station uses half of the Industrial Scientific Medical (ISM)band for its frequency hopping channels. The dip switches on the basestation 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 / 17Each base station must use a separate ISM half band. For moreinformation about setting the dip switches, refer to Installing the BaseStation on page 21.If other devices operating on the ISM band interfere with the T7406base, the other half of the band may be used to try to minimizeinterference. In this situation, install only one base station and threehandsets per location.Spare PartsYou can order spare parts for your T7406 telephone.

Installing the Base Station / 21Installing the Base StationThis section describes the base station and: how to mount the base station on a wall what programming is required before you connect the base station toyour system how to connect the base station to your systemThe T7406 cordless telephone operates on the same principle as a twoway radio. Therefore, the location of the base station affects the rangeof reception. The base station should not be installed where radio wavesare 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 halffeet) apart from a second base station. Always position the antenna at a90 angle to the base station.Base Station FeaturesThis section illustrates the base station for the T7406 system.AntennaBaseantenna(90 to basestation)LED indicates basestation has powerNote: When power is connected to the base station, the LED on thefront of the unit starts flashing.

22 / Installing the Base StationMounting BracketMountingbracketNotches match to bracket.T7406 Pre-installation ProgrammingBefore connecting the T7406 base station to your system, you must setup system programming for the handset lines.Have the system administrator set up this programming:1. Program Handsfree to Auto.2. Program a maximum of three lines to each handset.3. Assign Ring & Appear on the lines you assign to the handset.Note: Appear only does not allow the handset to wake fromHandset Asleep mode.4.Set the Page zone to None.Note: Handsets can send Page announcements, but they cannotreceive them.5.Set DND on Busy to Yes if you do not want your callsinterrupted with a ring tone when a second call comes in. Instead,the button flashes, indicating an incoming call.Other telephone programming is the same as for the M7310telephone, with the exception of the memory key locations.6.P0606142 01

Installing the Base Station / 23Before you start Ensure there is an AC power outlet within 1.5 meters (5 feet) of thebase station location. Ensure that the telephone lines from your system have been installedto the base station location.Mounting and Connecting the Base StationFollow these steps to mount and connect each base station.1. Use the mounting bracket as a template to position the basestation and mark the screw positions.2. Use screws to attach the mounting bracket to a wall or ceiling.3. Set the base station dip switches, located on the back of the basestation, to the required ISM frequency band.123Upper halfISM BandLower halfISM Band4. On the first base station you install,set the dip switches to operate in theupper half of the ISM band. From leftto right, set to Down-Up-Down.
