2. Link Wireless Telephone System Overview
Review this section if you are unfamiliar with the features and operation of the Link
150 M3 MCU.
2.1 System Operation
The 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, the
Base Station, and the Wireless Telephone, or handset. This diagram shows an
overview of system. Components are described below.

Gateway
The Link Wireless Telephone System
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 boxes (approximately 12” x 3” x 7”)
are typically installed in the telephone equipment room and provide connectivity
from the telephone system to the Link WTS. Each MCU is hard-wired to one or
more Base Stations, which in turn provides the wireless link to each of the handsets.
The MCU establishes the connection from the telephone line to the appropriate Base
Station in order to reach a handset.
The MCU supports four Base Stations and up to 16 handsets. Up to four Link 150
M3 MCUs can be linked together for extended coverage area. Chained MCUs
support up to 64 handsets maximum.
PN: 72-0075-05-F.doc Page 6

SpectraLink Corporation Facility Preparation
Link WTS – Link 150 M3 MCU
SpectraLink offers an analog MCU that works with telephone systems (CO, PBX or
key systems) with analog (loop start) ports. SpectraLink also offers digital MCUs that
work with the most common brands of telephone systems (PBX or key systems)
digital ports.
Base Stations
Act as a radio transceiver to provide the communications signal between the handset
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 handset user makes or receives a call, the handset and Base Station establish
a digital radio communication link. As the user moves throughout 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 handset 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 handsets to keep in contact as they move
throughout the building. The handsets use on-premises 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 the facility.)

3. Site Preparation
All site preparation steps should be completed prior to the arrival of the SpectraLink
field service engineer. A SpectraLink customer support representative will contact
the customer the week before the scheduled installation date to confirm that pre-
installation tasks have been completed. Upon confirmation, a SpectraLink field
service engineer will travel to the site to complete the system installation and train
the system administrator and handset users.
If upon arrival the SpectraLink field service engineer determines that the pre-
installation work has not been completed correctly, the engineer can: 1) leave the site
and reschedule the installation when the action items have been completed or
corrected, or 2) assist in preparing the site, and thus spend additional time in the
installation of the system. Because of the additional cost incurred by SpectraLink in
executing either option, the customer will be billed for the additional time at the
standard hourly rate plus expenses.
MCU location prepared. Typically the MCU is installed in the telephone
equipment room. This location must have sufficient backboard space. See
section 3.3
Determine Location of MCU for more information.
The correct number of cross-connect blocks (or equivalent) are installed and
connected to a 25-pair telco wire terminated with an RJ-21 male connector at the
MCU location. See section 4.4
Prepare Demarc Blocks for more information.
A two-pair cable to each Base Station as designated on the building floor plans.
See section 4.1
Run Cables to Base Station Locations for more information.
The Base Station wire is terminated at the appropriate cross-connect demarc
blocks as shown in sections 4.4
Prepare Demarc Block s and 4.7 Connect Cables

3.2 Materials Required by Customer
The following equipment must be provided by the customer.
Outlet Strip Recommended for installations with more than one MCU. This
will allow the MCUs to be turned on and off together.
Cross-Connect Block Required to connect the PBX ports and the Base
Stations to the MCU.
25 Pair Cables RJ-21 male at MCU end, required to connect the MCU to the
cross-connect blocks.
Backboard space The MCU is designed to be wall mounted to 3/4” plywood
securely screwed to the wall.
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 M3 MCU.
Recommended Quick Clip Fuse is available from Illinois Tool Works, Linx
Division, Model # SCP-2X2.
Mounting Hardware If the Base Stations will be mounted on finished walls or
ceilings, 4 to 5” long 1/4” bolts, nuts, and washers are required for each Base
Station mounted.
3.3 Determine Location of MCU
Each MCU is approximately 2.75” wide, 12.5” high, and 7” deep, and weighs about
five pounds. The unit is designed to be wall mounted over 3/4” plywood.
•Select a location for the MCU with sufficient backboard space and an available
electrical outlet.
•Since the front panel is used for cabling and as an operator’s console, mount the
unit so the front panel is accessible.
•The MCU must be within 250 feet of the PBX for a digital interface and within
2,200 feet of the Base Stations.
See your telephone system specifications for distance limitations for analog modules.
If your system has more than one MCU, the units should be mounted
vertically, side by side physically touching the adjacent unit. Do not stack
units on top of one another. Stacked MCUs can cause overheating and
failure.
PN: 72-0075-05-F.doc Page 11

4. Run Cable for System
4.1 Run Cables to Base Station Locations
The Base Station locations should be designated on the building floor plans provided
to the SpectraLink field service engineer. Base Stations can be mounted easily on
raised or acoustical ceiling tiles. Avoid locating Base Stations in high or hard-to-reach
places, as this will hinder maintenance, testing and/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
Pairs
Max Cable Feet
22 AWG
Max Cable Feet

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 at 772 KHz.
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.
The wire length between the MCU and each Base Station may not exceed
2,200 cable feet.
Install an extra 25 feet of wire at the Base Station to allow for possible
relocation.
PN: 72-0075-05-F.doc Page 12

SpectraLink Corporation Facility Preparation
Link WTS – Link 150 M3 MCU
4.2 Pull Cable
Pull the cable from the MCU location (usually in the telephone equipment room) to
the Base Station locations designated on the floor plans.
If the cabling exits the building, consult the telephone system manual, the
National Electrical Code (NEC) and local codes for instructions on
providing lightning and other over-current protection.
When cabling an external Base Station or a Base Station with wiring that
exits the building, protect all Base Station wiring with the Quick Clip Fuse
(Illinois Tool Works, Linx Division, SCP-2X2) before bridging with other
Base Station power leads.
Run all cable before attaching the RJ-45 connectors to the Base Stations. Label both
the demarcation-block end and the Base Station end of each wire with the Base
Station number using a wire-tie marker or other form of marker.
Remove bridge taps, multiples, or “Y” connections to the Base Station
wires; these will cause data transmission errors.
The area above some suspended ceilings is used as an environmental air
plenum. The NEC requires that wire installed in plenums be rated for
plenum installation.
4.3 Terminate Cable at Base Station Locations
After running the wire to the Base Station location, terminate the wire using an RJ-
45 modular crimp-on plug. Connect the data pair to pins 1 and 2 and the power pair
to pins 7 and 8.
If the connection uses more than two pair, refer to the table on the following page.
To avoid damage to the connectors or crimps, be sure to run the wire to
the Base Station before connecting the RJ-45 connectors.

If the wiring between the Link 150 M3 MCU and the telephone system
leaves the building, consult your telephone system manual for instructions
on providing adequate lightning and other over-current protection. All
MCUs (except the SCA analog interface MCU) are intended only for
connection to the isolated side of an on-premises PBX. The interfaces are
intended to connect to digital PBX ports that provide signals of 5Vp-p
(max) AC component and some PBXs provide a 48 V DC offset.
PN: 72-0075-05-F.doc Page 14

SpectraLink Corporation Facility Preparation

Based on the number and type of interfaces in the system, determine the number of
25-pair cables required to connect line ports and Base Stations to the demarcation
blocks.
The diagrams that follow provide an overview of the connections.
Multiple Power Pairs
Some sites may prefer to wire Base Stations to a separate demarc block in order to
split out power pairs.
Dedicated Line for Diagnostic Modem
The Link 150 M3 MCU 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.

4.5 Install Demarc Blocks
The demarcation blocks used to connect the telephone system and Base Stations to
the MCU should be installed on a typical telephone facility backboard. A 1/2 ” or
3/4” thick board mounted on the wall near the MCU is typical. Although this
manual uses 66 blocks as examples, any standard cross-connect blocks are
acceptable.
When cabling an external Base Station or a Base Station with wiring that
exits the building, protect all Base Station wiring with the Quick Clip Fuse
(Illinois Tool Works, Linx Division, SCP-2X2) before bridging with other
Base Station power leads.
If the cabling between the MCU and the telephone system leaves the
building, consult the telephone system manual, the NEC and local codes
for instructions on providing lightning and other over-current protection.
4.6 Assign and Program Ports
The wire contractor should inform the system administrator which port numbers
have been designated for the handsets and the remote diagnostics modem line.
The system administrator must assign extension numbers to the handsets and plan
the functions (trunk access, toll restrictions, system features, ringing options etc.) to
be programmed for the handsets. This programming will be done after the handsets
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.
For details, refer to the section of the LinkPlus Interface Guide for the type of
telephone system for the MCU in use at your location.
PN: 72-0075-05-F.doc Page 18

SpectraLink Corporation Facility Preparation
Link WTS – Link 150 M3 MCU
4.7 Connect Cables from Base Stations and Phone Lines to Demarc Blocks
Two-pair twisted cable from Base Stations installed throughout the facility converge
at the demarc block or backboard. Each MCU can support four Base Stations and up
to 16 handsets. The Base Station and handset cables are punched down onto the
demarc/cross-connect blocks as shown in the demarc block diagrams below. Refer
also to the diagrams in section 4.4 Prepare Demarc Blocks .
Photocopy the Base Station Location Form and Extension Assignments Worksheet
provided in this manual as needed. Use the forms to track the Base Stations and
handset port assignments connected to each MCU. As the SpectraLink field service
engineer makes each Base Station or handset connection, fill in the information on
the form to identify the position of the Base Station or handset (the building and
floor number, for example) and a detailed description of the location (perhaps a
room number). A copy of this form should be posted near the cross-connect block.
Up to four Base Stations can be connected on a single MCU. Each Base
Station uses two pair, one for data and one for power.
When cabling an external Base Station or a Base Station with wiring that
exits the building, protect all Base Station wiring with fuse protection.
One method is to use a Quick Clip Fuse (Illinois Tool Works, Linx
Division, SCP-2X2) to provide protection from external wiring.
If the wiring between the MCU and the telephone system leaves the
building, consult the telephone system manual, the NEC and local codes
for instructions on providing lightning and other over-current protection.
