SpectraLink 150 M3 MCU manual Run Cable for System, Run Cables to Base Station Locations

SpectraLink Corporation Link WTS Installation and Operation

4. Run Cable for System

4.1Run Cables to Base Station Locations

The Base Station locations should be designated on the building floor plans provided to the installer. Base Stations can be mounted easily on raised or acoustical ceiling tiles, or on the wall. Avoid locating Base Stations in high or hard-to-reach places, as this will hinder maintenance, testing, or repositioning.

Wire Specifications

The customer's wire contractor is responsible for adhering to all local codes

!for wiring.

SpectraLink recommends UL-Listed Wire that conforms to the following specifications for AWG, distance, and number of power pairs required for this installation.

Power	Max Cable Feet	Max Cable	Max Cable
Pairs	22 AWG	Feet	Feet
		24 AWG	26 AWG
1	1,100	750	470
2	2,200	1,500	940
3	2,200	2,200	1,400

!One additional pair is required for Data.

Attenuation must not exceed 6.8 dB/1,000 feet @ 772KHz.

Wire that is already installed (spare house cable) can be used when it is available. House cable will usually run from the MDF in the telephone equipment room to Intermediate Distribution Frames (IDFs) spread throughout the facility. Install new wire from the closest IDF to the Base Station. Be sure no bridge taps, multiples, or “Y” connections are created or present.

Determine the amount of wire needed to connect the Base Station to the MCU by scaling from a floor plan or a sketch, pacing, measuring, or estimating. Remember to include enough wire to reach the ceiling.

!2,200 cable feet.

Install an extra 25 feet of wire at the Base Station to allow for possible relocation.The wire length between the MCU and each Base Station may not exceed
