2. Link 150 Overview
Review this section if you are unfamiliar with the features and operation of the Link 150.
2.1 System Operation
SpectraLink's Link WTS is a wireless communication system that offers direct telephone
access for incoming and outgoing calls anywhere within a facility.
The Link WTS consists of three basic components: the Master Control Unit (MCU), the
Base Station and the Link Wireless Telephone. This diagram shows an overview of
system. Components are described below.
•Master Control Unit (MCU) – serves as the connecting point, or gateway, between
the Base Stations and the existing telephone system. One or more of these small boxes
(8 x 3 x 9 inches) are typically installed in the telephone equipment room and provide
connectivity from the telephone system to the wireless system. Each MCU is hard-
wired to one or more Base Stations, which in turn provides the wireless link to each of
the wireless telephones. The MCU establishes the connection from the telephone line
to the appropriate Base Station in order to reach a wireless telephone.
The MCU supports four Base Stations and up to 16 wireless telephones. Up to four
Link 150 MCUs can be chained together for extended coverage area. Chained MCUs
support up to 64 wireless telephones maximum.
SpectraLink offers an analog MCU that works with all premises telephone systems
(PBX or Key Systems) with analog (tip-ring or industry standard) ports. We also

SpectraLink Link 150 Installation and Operation
12/28/98 4
offer digital MCUs that work with certain brands of telephone systems' (PBX or key
systems) digital ports.
•Base Stations – act as a radio transceiver to provide the communications signal
between the wireless telephone and the MCU. Base Stations are slightly larger than a
smoke detector and are typically mounted on the ceiling, in strategic locations
throughout the facility. A single Base Station can provide radio coverage for an area
of 5,000 to 50,000 square feet depending on building obstructions. Base Stations may
be located up to 2,200 cable feet from the MCU.
When a wireless telephone user makes or receives a call, the wireless telephone and
Base Station establish a digital radio communication link. As the user moves around
the coverage area, calls are “handed off” to the Base Station that is able to provide the
best radio signal (typically the closest Base Station). These handoffs involve the
wireless telephone establishing a communication link with another Base Station and
dropping the previous link.
•Link Wireless Telephones – communicate with the Base Station using digital spread
spectrum transmission at 902-928 MHz. Employees can carry wireless telephones to
keep in contact as they move throughout the building. The wireless telephones use
on-premise wireless technology; they are not cellular or satellite phones. They are
connected to the facility's existing telephone system and, just like wired telephones,
can receive calls directly, receive transferred calls, transfer calls to other extensions,
and make outside and long distance calls (subject to the restrictions applied in your
facility.)

1. Telephone Lines – A standard RJ-11 connector is used to connect each line from the
telephone system to the MCU. There are three sizes of MCU, each with a different
number of ports. The X in the following part numbers represents the type of interface
on the MCU.
−MCA-450 – no ports; used only to provide extra Base Stations on a
multiple MCU system
−MCX-452 – 8 ports
−MCX-454 – 16 ports
2. Serial Number and Model Number – SpectraLink Customer Support will request
the serial number when you call them. The model number indicates the MCU type.
MCA-450, 452, or 454 are analog units; all other model numbers are digital units.
3. Power Jack – Connects to the AC adapter to supply power to the system. The label
next to the power jack is color coded to the label at the end of your power supply.
Use only the provided Class II AC Adapter with
output 24VDC, 1A.
4. Base Station Ports – Provide connection for up to four Base Stations.
5. IPC IN Port – Used only in systems with more than one MCU. The first unit in a
chain of MCUs has no connection to the IN Port.
6. IPC OUT Port – Used only in systems with more than one MCU or with an Open
Applications Interface (OAI) Gateway. The first unit’s OUT Port connects to the

SpectraLink Link 150 Installation and Operation
12/28/98 7
second unit’s IN Port. The OUT Port of the last unit in a chain is only used if the
system has an OAI Gateway.
7. Alarm Out Connector – The connector receives a 3.5mm stereo plug to provide a
relay contact closure when alarms are active.
This relay is designed for low voltage alarm
signaling only. Do NOT connect any device to the
relay that is operated directly from 110V power.
The relay contact supports a maximum alarm load
of 1 amp at 24VAC or 24VDC.

3. Site Preparation
3.1 Required Materials
The following equipment must be provided by the customer.
1. MCU Shelf – The MCU is designed to be mounted on a customer-supplied shelf.
2. Outlet Strip – Recommended for installations with more than one MCU. This
will allow the MCUs to be turned on and off together.
3. RJ-11 6-pin phone line cord – Up to sixteen cords will be needed to connect
telephone lines to each MCU. On most systems only the two center pins are used.
Refer to the appropriate Appendix for your telephone system for more information
4. Base Station connection cable –Two to four pairs for each Base Station. These
cables need 8-pin RJ-45 modular connectors on each end. Refer to 4.2
Connections to Base Stations for more information.
5. 66 Block and Quick Clip Fuse – Required with an RCO410 Outdoor Base
Station or when a Base Station is located in a separate building from the Link 150.
Recommended Quick Clip Fuse is available from Reliable Electric, Model # RSCP-
2.
6. Mounting Hardware – If the Base Stations will be mounted on finished walls or
ceilings, a 4-5" long ¼" bolt, nuts, and washers will be required for each Base
Station mounted.
3.2 Determine Location of MCU
The MCU is approximately 8 inches wide, 3 inches high, and 9 inches deep, and weighs
about 3.5 pounds. The unit is designed to be mounted on a 24- inch by 12-inch shelf,
usually placed in the telephone equipment room.
Select a location for the MCU with sufficient backboard space and an available outlet.
Since the front panel is used as an operator's console, mount the unit so the front panel is
accessible.
If your system has more than one MCU, plan to install the MCUs
side by side, not on top of one other. Stacked MCUs cause
overheating and intermittent failure.
3.3 Plan Telephone System Programming
The wire contractor should inform the system administrator which port numbers have been
designated for the wireless telephones and the remote diagnostics modem line.
The system administrator must assign extension numbers to the wireless telephones and
plan the functions (trunk access, toll restrictions, system features, ringing options etc.) to

SpectraLink Link 150 Installation and Operation
12/28/98 10
be programmed for the wireless telephones. This programming will be done after the
wireless telephones are registered, but will be faster if it is planned in advance by verifying
the parameters and features on the current telephone system and wired phones.
One of these scenarios concerning how the wireless telephones are programmed should
apply to this site:
•All Wireless Telephones are Programmed Alike – All SpectraLink telephones will
be programmed exactly the same. Program one SpectraLink telephone and use it as a
model for all other telephones.
•Groups of Wireless Telephones are Programmed Alike – SpectraLink telephones
are grouped into classes that are programmed alike. Program the model SpectraLink
telephones then use them as a model to program the other telephones.
•All Wireless Telephones Different – All SpectraLink telephones are programmed
differently, so each telephone will be programmed individually.
For details, refer to the Appendix for the type of telephone system for the MCU you are
using.
Use the Wireless Telephone Planning Worksheet at the end of this document to track the
port numbers, extensions, users, and features assigned to your telephones.

SpectraLink Link 150 Installation and Operation
12/28/98 11
4. Run Wire for System
4.1 Connections to the Telephone System
4.1.1 Connections for Wireless Telephones
The MCU is connected to the existing telephone system using standard RJ-11 6-position,
2- or 4-conductor phone line cord. Up to sixteen cords (one for each wireless telephone)
will be needed to connect telephone lines to each MCU.
Wiring details may differ based on the model of MCU you are installing.
Refer to the appropriate Appendix.
Inform the system administrator which ports have been designated for use with the
wireless telephones.
If the wiring between the Link 150 and the telephone system leaves the
building, consult your telephone system manual for instructions on providing
adequate lightning and other over-current protection. The telephone system
must be listed with a safety agency such as Underwriter’s Laboratories (UL).
Isolation between the public telephone network and the Link 150 is provided
by the listed telephone system equipment.
4.1.2 Dedicated Line for Diagnostic Modem
The Link 150 can be accessed remotely using an internal modem. To use the modem for
remote access, a dedicated dial-in line must be provided. On digital interface systems this
line must be terminated as a digital extension to the MCU.
Inform the system administrator which port has been designated for the modem.
4.2 Connections to Base Stations
The Base Station locations should be designated on the building floorplans 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.
The customer's wire contractor is responsible for adhering to all local codes
for wiring.

SpectraLink Link 150 Installation and Operation
12/28/98 12
Most installations run four pair cable, but you can run cable with fewer pairs, subject to
the length restrictions in the following table. The wire should be Level 3 or better
telephone wire.

4.2.1 Pull Wire to Base Station Locations
Pull the wire from the MCU location (usually in the telephone equipment room) to the
Base Station locations designated on the floorplans.
1. Determine the amount of wire needed to connect the Base Station to the MCU by
scaling from a floorplan or a sketch, pacing, measuring, or estimating. Remember
to include enough wire to reach the ceiling.
2. Pull the wire between the Link 150 and the Base Station locations. Wire a surface
mount or similar jack to each end. Refer to 4.2.2 Terminate Wire to Base
Stations below.
If the wiring exits the building, refer to Wire Outdoor Base Stations below.
3. Create a permanent Base Station cable for each Base Station. Use 8 conductor
silver satin telephone cord or 22 AWG category 3 wire and crimp 8-pin modular
connectors to both ends.
