IMPORTANT SAFETY INFORMATION
Follow these general precautions while installing telephone equipment:
•
Never install telephone wiring during a lightning storm.
•
Never install telephone jacks in wet locations unless the jack is specifically designed for
wet locations.
•
Never touch uninsulated telephone wires or terminals unless the telephone line has
been disconnected at the network interface.
•
•
Use caution when installing or modifying telephone lines
When installing Base Stations outside or in buildings other than the one containing the
System Controller, take the following precaution:
If wiring for a Base Station exits a building—whether to reach an outdoor Base Station
location or to reach a Base Station in another building—the wiring must be protected at
both ends by a Quick Clip Fuse from Illinois Tool Works, Linx Division, model
number SCP-2X2. The Quick Clip Fuse replaces the bridging clips on the 66 blocks for
all four connections to the non-internal Base Station.

Installation has three phases. In most cases, a separate person is responsible for each
phase.
1. Site preparation and wire installation: This is usually done by a wire technician or
contractor.
2. Installing the SpectraLink system: This is done by SpectraLink or one of our
certified distributors.
3. Programming the customer’s telephone system to work with the SpectraLink
system: This is usually done by the customer’s system administrator or
technician.
Because these major steps require some parallel activities, it is important to
coordinate the activities among the persons involved.

3. Link Wireless Telephone System Overview
Review this section if you are unfamiliar with the features and operation of the Link
WTS.
3.1 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 Link Wireless Telephones, or handsets. This diagram shows an
overview of the system. Components are described below.

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 Link
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.

SpectraLink Corporation
Installation and Operation
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. We also offer 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 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 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 your facility.)

4. Site Preparation
4.1 Required Materials
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 telephone switch 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.
† Base Station Mounting Hardware If the Base Stations will be mounted on
finished walls or ceilings, a 4 to 5” long 1/4” bolt, nuts, and washers will be
required for each Base Station mounted.
4.2 Determine Location of MCU
Each MCU is approximately 2.75” wide, 12.5” high, and 7” deep, and weighs about 5
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
outlet.
• The MCU must be within 2,200 feet of the Base Stations.
• All digital interface modules must be within 250 feet of the telephone system.
• See your telephone system specifications for distance limitations for analog
modules.
• Since the front panel is used for cabling and as an operator’s console, mount the
units so the front panel is accessible.
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.

5. Run Cable for System
5.1 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, or on the wall. 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.

One additional pair is required for data.
Attenuation must not exceed 6.8 dB/1,000 feet at 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.
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.
ꢀ
5.2 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.
PN: 72-0075-01-F.doc
Page 13
SpectraLink Corporation
Installation and Operation
Link WTS – Link 150 M3 MCU
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.
5.3 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 analog interface SCA-5XX) are intended only for
connection to the isolated side of an on-premises telephone switch. The
interfaces are intended to connect to digital telephone switch ports that
provide signals of 5Vp-p (max) AC component, and some telephone
switches provide a 48 V DC offset.
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 which 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.

5.5 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.
5.6 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 for the type of PBX in use at your location.

5.7 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 Link Wireless Telephone 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 5.4 Prepare Demarc Blocks and section
6.3 Install MCUs
.
Photocopy the and 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.

6.3 Install MCUs
Mount MCUs to Wall
The MCUs are designed to be mounted on a backboard of 3/4” plywood, securely
fastened to the wall. Mount the MCUs vertically, side by side, using 2.75” spacing
center-to-center for each unit. Do not stack MCUs on top of one another.
To mount the MCUs:
1. Using a 1/8” drill bit, drill four pilot holes, on 2” x 12.1” centers.
2. If installing only one MCU, insert the #8 x 3/4” screws in the pilot holes and
tighten, leaving a 1/8 to 1/4” gap from the wall.
3. If installing more than one MCU, the ESD bonding strap(s) must be installed
between adjacent units:
3.1 Remove the screws from the bottom of adjacent units.
3.2 Place the ESD strap over the pilot holes that span two units, and hold it
against the plywood backboard.
3.3 Place the star washer on top of the ESD strap.
3.4 Insert the #8 x 3/4” screw and tighten to leave 1/8 to 1/4” gap from the
wall.
3.5 Repeat for all ESD straps.
4. Slide the MCU over the screws until it drops in place.
5. Tighten screws fully.
6. When installing an analog interface MCU (SCA-5XX), the grounding terminal in
the rear panel of each unit must be electrically connected to earth ground.
Consult the NEC and local codes for instructions on making the connection to
the ground.
Connect MCU to Demarc Blocks
Connect the male RJ-21 connector from the appropriate demarcation block to the
designated RJ-21 connector (A or B) on each MCU. Secure the cables using the
keeper.

Connect Power
1. Connect the power plug from the AC adapter to the jack labeled PWR on the
MCU.
Use only the provided Class II AC Adapter with output 24VDC, 1A.
For installations with more than one MCU, use an outlet strip with a
built-in power switch. This allows the MCUs to be turned on and off
together.
ꢀ
2. Plug the AC adapter into a 110VAC outlet or switch on the outlet strip to apply
power to the MCU.
Set Switch Interface Type
The following steps explain how to assign a switch interface type to the MCU. This
procedure must be done in on each MCU.
1. Power on the MCU with the mode switch in the NORMAL position.
Because the MCU does not have a switch type assigned, it will alarm (the ERROR
LED will flash along with STATUS LEDs 1, 2, 3, 4, and 5). This should take less
than 2 minutes.
2. Power off the MCU.
3. Move the mode switch to ADMIN and power on the MCU. Within 15 seconds,
STATUS LEDs 2 and 4 will light.
4. Press the STEP button three times.
STATUS LEDs 1, 2, and 4 must be lit. LINE LEDs 1 through 8 (indicating an
unconfigured MCU) should also be lit.
If any other combination of LINE LEDs is lit, then a switch type has already been
selected. Go to step 5 to pick the desired switch type.
5. Press the DEL/ENTER button to select the correct switch interface type. With each
press of the DEL/ENTER button, a different series of LINE LEDs will be lit.
Continue to press DEL/ENTER until the correct LINE LEDs are lit. Use the
following list to select the desired switch interface.

6. Move the mode switch back to NORMAL.
7. The MCU will cycle through diagnostic testing. When the system is ready for use,
the ERROR LED should be off, and the LED for the MCU Number (1 to 4) will
be lit. This should take less than two minutes.
If the LED for the MCU ID does not light, or if an MCU ID is duplicated, there
is most likely a problem with the IPC cabling. If the system displays an error
refer to section 9.1 Troubleshoot Error Codes
.
8. If you select a switch type that is not supported by the MCU type, the system will
alarm. The ERROR LED will flash along with STATUS LEDs 4 and 5. For
example, this alarm will display if you assign switch type NEC to an SCB-5XX –
Executone MCU.
If this alarm displays, use the table above to verify that your MCU type supports
the selected switch type. If you need to change the switch type, repeat steps 2
through 6.

6.4 Install Base Stations
Be sure the Base Station is positioned clear of anything that might damage it. The
Base Station should be well above head height, away from doors and other objects
that might strike it, and away from areas open to the elements or possible water
leaks.
Check your location for other radio antenna devices and place the Base Stations to
avoid interference. Leave enough slack wire (approximately 25 feet) to account for
possible future Base Station moves.
Mount Base Stations on Dropped Tile Ceilings
A ceiling clip and plastic bolt are supplied to install Base Stations on the drop ceiling
rails (T-bars) used to support acoustical tile. The plastic bolt screws into the top of
the Base Station, then snaps into the ceiling clip which has been attached to the rails
that hold the acoustical tile. The fastener is designed for use on 15/16” wide rails.
1. Attach the metal fastener to the rail (T-bar) supporting the dropped ceiling by
rotating it into position until it snaps into the locked position.
2. Screw the plastic bolt to the 1/4” x 20 captive nut into the top of the Base
Station.
3. Slide the bolt into the exposed prongs of the metal clip until it snaps into
position.
4. When properly attached, the Base Station should sit almost flush against the
ceiling, and be tightly attached to the clip and T-bar grid work.
5. Once the Base Station is anchored to the fastener, lift the acoustical tile and plug
the RJ-45 8-pin modular plug into the connector on the top of the Base Station.
• The LED will blink red and green as the system software downloads to the
Base Station and the Base Station is tested.
• When the LED blinks amber, the system is ready for operation.
• When the LED blinks green, a telephone has established a radio link with
that Base Station.
• If the LED turns solid red, there should be an error message on the MCU’s
PN: 72-0075-01-F.doc

Installation and Operation
Link WTS – Link 150 M3 MCU
Mount Base Stations On Finished Ceilings
If your site does not have a dropped tile ceiling, the Base Station can be mounted to
a finished ceiling or wall with a 4 to 5” long 1/4” –20 TPI plastic or nylon screw or
bolt (such as a lag screw).
The customer’s wire contractor is responsible for this installation.
ꢀ
1. Drill two holes approximately 1” apart. Make the holes large enough to
accommodate the RJ-45 connector and a bolt to secure the Base Station.
2. Insert a wide washer above the ceiling, then screw the bolt into the beam or
ceiling.
3. Insert three nuts on the bolt, then screw the Base Station into the bolt, being
careful not to insert the bolt more than 1/3”, five full turns, into the Base
Station.
4. If the ceiling is open with I-beams or pipe construction, mount the Base Station
with I-beam clamps or pipe clamps.

6.5 Install Outdoor Base Stations
Outdoor Base Stations are equipped with a protective enclosure, designed to be
mounted to a wall or pole. After the enclosure is mounted, the Base Station is inserted
in the enclosure and connected.
Only RCO Base Stations can be used outdoors.
ꢀ
The customer’s wire contractor is responsible for wiring and mounting the outdoor
Base Station enclosure. The contractor is responsible for supplying screws, brackets,
and other appropriate hardware.
Wire and Connect Outdoor Base Stations
If the wiring for a Base Station exits a building—whether to reach an
outdoor Base Station location or to reach a Base Station in another
building—it should be equipped with primary protection according to the
NEC and/or local codes.
Wiring that exits the building must also be fuse protected at both ends.
For example, use a Quick Clip Fuse from Illinois Tool Works, Linx
Division, model number SCP-2X2. Insert the Quick Clip fuses in place of
bridging clips on a 66 block for the non-internal Base Station circuits.
1. Mount the outdoor Base Station enclosure to a wall or pole. The enclosure
should be attached at the highest point available that will provide central
coverage for the outdoor area.
2. Insert the Base Station cable through the compression fitting and tighten the
fitting.
3. Wire the Base Station connector just as you wired the RJ-45 connectors for the
indoor Base Stations.
4. Place the Base Station inside the enclosure with the part number label facing the
back of the enclosure.
5. Screw the protective cover onto the Base Station enclosure.

7. Connect and Register Handsets
7.1 Set Up Diagnostic Modem
Each MCU has an internal modem feature that allows SpectraLink technicians to dial
into the system for troubleshooting and maintenance. The modem is enabled on
Line 1 when no handset is registered to Line 1. When enabled, the modem will auto-
answer an incoming call to that line.
This internal modem uses proprietary communication software. You
cannot use commercial software packages to access this software. If you
have a multiple MCU system, you only need to enable one modem line,
on Line 1 of MCU 1. Line 1 positions on the other MCUs can be used for
handsets.
ꢀ
To set up the diagnostic modem:
1. Connect an analog Direct Inward Dial (DID) line to Analog Interface MCUs
(SCA-5XX) or a digital DID line to Digital Interface MCUs.
2. Move the mode switch to the REGISTER position. The LED for Line 1 should be
off, indicating that no handset is registered to Line 1. If the LED is on then a
.
3. Dial the number associated with the DID line. After one or two rings, you
should hear the high-pitched modem answer tone.
7.2 Register Handsets
Before a handset can be used it must be registered to a line on one of the MCUs.
While handsets are being registered, the system will continue normal operation.
Use the filled out by the system administrator to be sure you are correctly assigning
each handset to its port and extension number.
All lines are unregistered when shipped from the factory. However, if you are
replacing a failed MCU you may not need to register the handsets. Refer to section 9
System Administration for details.
Line 1 MCU 1 may be skipped to allow for remote access through the
diagnostic modem.
Each MCU supports eight simultaneous conversations. To optimize
performance and reduce the possibility of call blocking, distribute the
handsets evenly across all MCUs.
ꢀ
To register a handset to your system do the following:
1. Be sure all unregistered handsets are powered off and that there is a Base Station
plugged in and within range of the handsets to be registered.
2. Move the mode switch to the REGISTER position. (If your system has more than
one MCU, be sure to move the switch only on the correct MCU.) The LED
which indicates the Box ID (1 through 4) may change. This is normal and is not
an error.
PN: 72-0075-01-F.doc
Page 31
SpectraLink Corporation
Installation and Operation
Link WTS – Link 150 M3 MCU
The LINE indicator LEDs now show the registration status of each line.
• If the LED is on, a handset is registered to the line.
• If the LED is off, no handset is registered to the line.
3. Press the STEP button until the LED for the line to be registered flashes.
• If the LED is flashing, that line is selected. A flash with the LED mainly off
indicates no handset registered; a flash with the LED mainly on indicates a
handset is registered to the selected line.
• Initially Line 2 will flash. This is because Line 1 is usually set up as the remote
access diagnostic modem. To register a handset to Line 1, press the STEP
button until Line 1 flashes.
• If the desired line already has a handset registered to it, follow the procedure
outlined below to unregister the handset, then return to this step.
4. Turn on the handset to be registered by holding down the PWR key until the
handset beeps twice. After a few seconds, the line indicator LED on the MCU
will shine solid red. Once the handset is registered, the LED for the next line
begins to flash.
5. To assign the extension number, hold down the FCN key until Volume Level
displays. Press the # > key until EXTENSION displays on the handset. Press 0, then
enter the correct extension number. Press END when finished.
6. Repeat steps 3 through 5 for all handsets to be registered.
7. When all handsets are registered, return the mode switch to the NORMAL
position.
7.3 Unregister Handsets
If the desired line already has a handset registered to it, follow this procedure to
unregister the handset.
1. Move the mode switch on the MCU to the REGISTER position. If your system has
more than one MCU, be sure to move the switch on the correct MCU. The LINE
indicator LEDs now show which lines have handsets registered.
2. Use the STEP button to select the line to be unregistered. The LINE indicator LED
for a line that has a handset registered to it will flash with the LED mainly on.
3. Press the DEL/ENTER button. The LINE indicator LED for the selected line will be
off with a short on flash
4. Register the new handset or return the mode switch to the NORMAL position.
7.4 Program Handset Features
PBX and Key Systems provide users with special features such as hold, transfer,
conference, camp on, and speed dial. These features can be accessed via the handset,
but the telephone system or Link 150 M3 MCU must be programmed to allow
access to these features from the handset. For information on programming the
switch to operate with the handsets, refer to for your PBX
PN: 72-0075-01-F.doc

• If the Link 150 M3 MCU is connected to your telephone system via analog lines,
refer to the for analog systems.
• If your Link 150 M3 MCU is connected to a digital key telephone system or
PBX, refer to the document that deals specifically with your brand of telephone
system.
7.5 Test Handsets
Verify proper registration and operation of each handset by performing the
following steps.
1. Press the START key on each handset. The extension number should clear and
you should hear dial tone. On some digital systems, depending on how the
telephone system is programmed, you may have to select a line to get dial tone.
2. Place a call to each handset to verify ring, answer, clear transmit, and clear
receive audio.
3. Verify all programmed features on each handset.
4. Press the END key. The LINE indicator should turn off.

9.1 Troubleshoot Error Codes
When an alarm is detected, the ERROR LED will light and the MCU’s STATUS LEDs
will display an alarm code.
If the error code refers to a Base Station problem, the Base Stn LED will indicate
which Base Station has the problem. If more than one Base Stn LED is on, the error
code refers to the lowest numbered Base Station with an error. Use the STEP button
to select another Base Station to display its error code.
For additional assistance in troubleshooting your system, please contact the
SpectraLink Customer Support Hotline at (800) 775-5330. The hotline is open
Monday through Friday, 6 a.m. to 6 p.m. Mountain time.
9.2 Troubleshoot Handset Features
If handset features are not working properly, disconnect the handset from the MCU
and plug a wired telephone into the port. The telephone should be the same type as
the emulated telephone. Refer to the appropriate section of the LinkPlus Interface
Guide for your PBX type.
Test the features on the wired telephone.
• For analog MCUs, verify that feature access codes and switchhook flash work
correctly.
• For digital MCUs, verify that features are assigned to the correct keys and are
working properly. Refer to the appropriate for button mapping information for
the brand of telephone system at your location.
Certain four-wire telephones (such as MERLIN LEGEND) use a
different connector on the phone than on the back of the MCU.
Therefore you may need phone cord or an adapter to perform these tests.

1. Remove power from the replacement MCU. There should be no IPC cables
connected to the IPC ports.
2. Slide the mode switch on the replacement MCU to the ADMIN position.
3. Apply power.
4. Press the STEP button until the STATUS LEDs light 2, 3, and 4 of the replacement
MCU.
5. Press the DEL/ENTER button.
6. Remove power from the unit.
7. Slide the mode switch to the NORMAL position.
Connect the Replacement MCU
1. Remove the failed MCU from the IPC chain
2. Connect the replacement MCU in the position vacated by the failed MCU.
3. Reconnect the IPC cables for the chain. Double-check that the IN and OUT ports
are correctly connected.
4. Apply power to the MCU.
5. After a few moments each MCU in the chain should have a unique box ID
number (1 through 4), shown on the STATUS LEDs. If this is not the case,
recheck the IPC wiring.
6. If the replacement MCU has STATUS LED 3 and 4 lit, the configuration data has
not been successfully shared. Most likely, the replacement MCU was powered up
before it was correctly attached to the IPC chain. Repeat the entire replacement
procedure.

9.6 Replace a Base Station
To replace a Base Station, unplug the existing Base Station and plug in the new Base
Station.
• The LED will blink red and green as the system software downloads to the Base
Station and the Base Station is tested.
• When the LED blinks amber, the system is ready for operation.
• When the LED blinks green, a handset has established a radio link with that Base
Station.
• If the LED turns solid red, there should be an error message on the MCU’s
STATUS LEDs and the MCU ERROR LED should be lit.

12. Technical Parameters
12.1 Select Alternate Spread Spectrum Sequence
The Link WTS uses spread spectrum radio transmission. Spread spectrum takes a
discrete signal, such as a digitized voice conversation, and spreads it over a wide
range of frequencies rather than transmitting at a single carrier frequency. The
frequency range may need to be adjusted if other wireless devices in your facility,
such as data terminals or bar code readers, share the same frequency band.
Units shipped from the factory are preset to operate on sequence 1, which spans the
entire spectrum from 902MHz to 928MHz. If interference between the Link WTS
and other 900MHz radio devices is anticipated or observed, any one of six alternate
sequences can be selected.
Determine the frequency band of the interfering device, then use the frequency
ranges below (given in MHz) to select the best interference avoidance pattern for the
situation.
Sequence

902-915
902-909 & 921-928
914-928
902-904 & 909-921
904-910 & 920-928
908-922
To change a system to an alternate sequence, perform the following steps for each
MCU.
1. Wait for any calls in progress to end. Power the system off, then slide the mode
switch to the REGISTER position.
2. Power the system on. STATUS LEDs 5 and 1 should be lit, indicating frequency
selection mode. One of the LINE LEDs from 1 to 7 will be indicating the current
frequency selected for the MCU.
3. Use the STEP button to select the desired new sequence.
4. Press the DEL/ENTER button. The LED indicates the new frequency that has been
selected.
5. Return the mode switch to the NORMAL position.
6. Repeat steps 1 through 5 for each MCU of a multi-unit installation.

12.2 Change Companding
The factory setting on the Link 150 M3 MCU is compatible with Mu-law
companding (signal compression), which is the standard used by most PBXs in
North America. Systems outside North America generally use A-law companding. If
the PBX companding is incompatible with the MCU’s, the handsets will have
distorted or hissing dial tone, and voice will be unintelligible.
Before you begin, if the system has more than one MCU, erase the
configurations from all MCUs except MCU 1. Refer to section 9.5 Replace
an MCU for instructions.
ꢀ
To change the default from Mu- to A-law on the Link 150 M3 MCU follow these
steps.
1. Power the system off.
2. Slide the mode switch on the first MCU to the ADMIN position.
3. Power the system on. STATUS LEDs 2, 3, and 4 will be solid green.
4. Press the STEP button once. STATUS LEDs 2 and 5 will be lit.
5. If the LED for LINE 1 is lit, the system is set for Mu-law.
If the LED for LINE 2 is lit, the system is set for A-law.
6. Press the DEL/ENTER button to toggle between Mu-law and A-law.
7. When the correct LINE LED is lit, return the mode switch to the NORMAL
position.
