2. Link 150 Model 2 Overview
Review this section if you are unfamiliar with the features and operation of the Link 150
Model 2.
2.1 System Operation
The Link 150 Wireless Telephone System (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.

The Link 150 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 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.
08/11/99 Page 3
SpectraLink Corporation Link 150 M2 Installation and Operation
The MCU supports four Base Stations and up to 16 Wireless Telephones. Up to four
Link 150 MCUs can be linked together for extended coverage area. Chained MCUs
support up to 64 Wireless Telephones maximum.
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 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.)

3. Site Preparation
3.1 Required Materials
The following equipment must be provided by the customer.
1. Outlet Strip – Recommended for installations with more than one MCU. This
will allow the MCUs to be turned on and off together.
2. Cross-Connect Block – required to connect the PBX ports and the Base Stations
to the MCU.
3. 25 Pair Cables – RJ-21 male at MCU end, required to connect the MCU to the
cross-connect blocks.
4. Backboard space – the MCU is designed to be wall mounted to ¾” plywood
securely screwed to the wall.
5. 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 Illinois Tool Works, Linx Division, Model #
SCP-2X2.
6. Base Station 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
Each MCU is approximately 2.75 inches wide, 12.5 inches high, and 7 inches deep, and
weighs about 5 pounds. The unit is designed to be wall mounted over ¾”plywood.
Select a location for the MCU with sufficient backboard space and an available outlet.
Since the front panel is used for cabling and as an operator's console, mount the units so
the front panel is accessible.
The MCU must be within 2,200 feet of the Base Stations.
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.

SpectraLink Corporation Link 150 M2 Installation and Operation
4. Run Cable for System
4.1 Run Cables to Base Station Locations
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.
4.1.1 Wire Specifications
The customer's wire contractor is responsible for adhering to all local codes
SpectraLink recommends UL-Listed Wire that conforms to the following specifications
for AWG, distance, and number of power pairs required for this installation.
for wiring.
Power
Pairs
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 floorplan or a sketch, pacing, measuring, or estimating. Remember to include
enough wire to reach the ceiling.

relocation.
SpectraLink Corporation Link 150 M2 Installation and Operation
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 floorplans.
If the cabling exits the building, consult the telephone system manual, the
NEC, and local codes for instructions on providing lightning and other overcurrent 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 National Electric Code 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 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-416 and SCA-408) are intended only for connection to the isolated side
of an on-premise 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.
Based on the number and type of interfaces in the system, determine the number of 25pair cables required to connect line ports and Base Stations to the demarcation blocks.

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 ½" or ¾" thick
board mounted on the wall near the MCU is typical. Although this manual uses 66blocks 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 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
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.
For details, refer to the section of Switch Programming (PN 72-0060-02) for the type of
telephone system for the MCU in use at your location.

SpectraLink Corporation Link 150 M2 Installation and Operation
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
Wireless Telephones. The Base Station and 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 4.4.
Photocopy the Base Station Location Form and Extension Assignments Worksheets
(Appendix D and E) as needed. Use the forms to track the Base Stations and Wireless
Telephone port assignments connected to each MCU. As the installer makes each Base
Station or Wireless Telephone connection, fill in the information on the form to identify
the position of the Base Station or Wireless Telephone (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 2 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.

5.3 Install MCUs
5.3.1 Mount MCUs to Wall
The MCUs are designed to be mounted on a backboard of ¾ inch plywood, securely
fastened to the wall. Mount the MCUs vertically, side by side, using 2.75 inch 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 inch by 12.1 inch centers.
2. In each pilot hole, sandwich a star washer between the ESD bonding strap and the
backboard, then insert the screw (#8 panhead wood screw, 3/4 inch long) and
tighten it, leaving approximately 1/8 to ¼ inch gap from the wall.
3. Slide the MCU over the screws until it drops in place.
4. Tighten screws fully.
5. When installing an SCA-408 or SCA-416, 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.

SpectraLink Corporation Link 150 M2 Installation and Operation
5.4 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.
5.4.1 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.
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.
4. 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
status LEDs. Refer to Troubleshoot Error Codes.
Page 22 08/11/99
SpectraLink Corporation Link 150 M2 Installation and Operation
5.4.2 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 4-5" 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 one inch 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 inch, five full turns, into the Base
Station.
If the ceiling is open with I-beams or pipe construction, mount the Base Station with Ibeam clamps or pipe clamps.
08/11/99 Page 23
SpectraLink Corporation Link 150 M2 Installation and Operation
5.5 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.
5.5.1 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 National Electric Code (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.

6. Connect and Register Wireless Telephones
6.1 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 Wireless Telephone is registered to Line 1. When enabled, the modem will
autoanswer an incoming call to that line.
This internal modem uses proprietary communication software. You cannot
To set up the diagnostic modem:
1. Connect an analog Direct Inward Dial (DID) line to Analog Interface MCUs
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 Wireless
Telephones.
(SCA-416 or 408) 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 Wireless Telephone is registered to Line 1. If the LED is on
then a Wireless Telephone is registered to the line. Refer to Unregister Wireless
Telephones.
3. Dial the number associated with the DID line. After one or two rings, you should
hear high-pitched modem answer tone.
6.2 Register Wireless Telephones
Before a Wireless Telephone can be used it must be registered to a line on one of the
MCUs. While Wireless Telephones are being registered, the system will continue normal
operation.
Use the Wireless Telephone Planning Worksheet filled out by the system administrator to
be sure you are correctly assigning each Wireless Telephone 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 Wireless Telephones. Refer to the System
Administration document for details.
Line 1 MCU 1 should 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
Wireless Telephones evenly across all MCUs.
08/11/99 Page 25
SpectraLink Corporation Link 150 M2 Installation and Operation
To register a Wireless Telephone to your system do the following:
1. Be sure all unregistered Wireless Telephones are powered off and that there is a
Base Station plugged in and within range of the Wireless Telephones 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 (1-4) may change. This is normal and is not an error.
The Line Indicator LEDs now show the registration status of each line.
− If the LED is on, a Wireless Telephone is registered to the line.
− If the LED is off, no Wireless Telephone 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 Wireless Telephone registered; a flash with the LED mainly on
indicates a Wireless Telephone 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 Wireless Telephone to Line 1,
press the STEP button until Line 1 flashes.
− If the desired line already has a Wireless Telephone registered to it, follow the
procedure outlined below to unregister the Wireless Telephone, then return to
this step.
4. Turn on the Wireless Telephone to be registered by holding down the PWR key
until the Wireless Telephone beeps twice. After a few seconds, the line indicator
LED on the MCU will shine solid red. Once the Wireless Telephone 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 (NEXT) until EXTENSION displays on the Wireless
Telephone. Press 0, then enter the correct extension number. Press END when
done.
6. Repeat steps 3-5 for all Wireless Telephones to be registered.
7. When all Wireless Telephones are registered, return the mode switch to the
NORM position.
Page 26 08/11/99
SpectraLink Corporation Link 150 M2 Installation and Operation
6.3 Unregister Wireless Telephones
If the desired line already has a Wireless Telephone registered to it, follow this procedure
to unregister the Wireless Telephone.
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 Wireless Telephones registered.
2. Use the
STEP button to select the line to be unregistered. The line indicator LED
for a line that has a Wireless Telephone 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 Wireless Telephone or return the mode switch to the NORM
position.
6.4 Program Wireless Telephone 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 Wireless
Telephone, but the telephone system or Link 150 must be programmed to allow access to
these features from the Wireless Telephone. For information on programming the switch
to operate with the Wireless Telephones, refer to Switch Programming – Link 150
Model 2 (PN 72-0060-02).
• If the Link 150 is connected to your telephone system via analog lines, refer to
Programming Analog System Functions (in the Switch Programming document or
Appendix B of this document).
• If your Link 150 is connected to a digital key telephone system or PBX, refer to the
section of the Switch Programming document that deals specifically with your brand
of telephone system.
6.5 Test Wireless Telephones
Verify proper registration and operation of each Wireless Telephone by performing the
following tests.
• Press the START key on each Wireless Telephone. 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.
• Place a call to each Wireless Telephone to verify ring, answer, clear transmit, and
clear receive audio.
• Verify all programmed features on each Wireless Telephone.
• Press the END key. The line indictor should turn off.
08/11/99 Page 27

7. Site Certification
The installer should not leave the site before contacting SpectraLink to perform
remote install verification.
Contact a SpectraLink engineer on the technical support line 800-775-5330. The hours of
operation are 7:00 a.m. to 6:00 p.m. Mountain Time, Monday through Friday, excluding
holidays.
The engineer will connect with the diagnostic modem, verify calling functions, and listen
while you perform a walk test. The walk test will require you to walk the inside
perimeter of the coverage area. If all Base Stations are running, note any areas with
heavy static or clarity problems and report it to a SpectraLink engineer.
The installation is not complete until these certification steps have been performed.
Do not hand out Wireless Telephones at a site that has not been certified.

8. System Administration
8.1 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 Station LED will indicate
which Base Station has the problem. If more than one Base Station 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.
Contact SpectraLink Customer Support at (800) 775-5330 (Monday through Friday,
7:00 a.m. to 6:00 p.m. Mountain Time) for additional assistance in troubleshooting your
system.
8.2 Troubleshoot Phone Features
If Wireless Telephone features are not working properly, disconnect the Wireless
Telephone 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 Switch
Programming (72-0060-02) for more details.
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 section of Switch Programming (72-0060-
02) 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.

8.5 Replace an MCU
When the system has more than one MCU, each MCU contains a complete set of
configuration information for the entire system. This includes Wireless Telephone
registration information, function definitions, and frequency sequence selection.
This Configuration Sharing feature allows a failed MCU in a multi-unit installation to be
replaced without having to register the Wireless Telephones again.
To replace a failed MCU, first clear the configuration information on the replacement
MCU, then replace the failed MCU.
8.5.1 Clear Configuration on Replacement MCU
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 NORM position.
8.5.2 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.
− After a few moments each MCU in the chain should have a unique box ID
number (1-4), shown on the status LEDs. If this is not the case, recheck the
IPC wiring.
− 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.

A. Technical Parameters
1. Select Alternate Spread Spectrum Sequence
The SpectraLink system 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 SpectraLink system 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 Frequencies Used by SpectraLink
1 902-928
2 902-915
3 902-909 & 921-928
4 914-928
5 902-904 & 909-921
6 904-910 & 920-928
7 908-922
To change a system to an alternate sequence, perform the following steps for EACH
MCU.
1. Wait for any calls in progress to end. Remove power from the MCU, then slide
the mode switch to the
REGISTER position.
2. Apply power. Status LEDs 5 and 2 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 NORM position.
6. Repeat Steps 1-5 for each MCU of a multi-unit installation.
08/11/99 Page 37
SpectraLink Corporation Link 150 M2 Installation and Operation
2. Change Companding
The factory setting on the Link 150 Model 2 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 Wireless Telephones 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 Replace an MCU for
instructions.
To change the default from Mu- to A-law on the Link 150 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.
4. Press the
STEP button until status LEDs 1, 2, and 5 are 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 NORM position.

B. Program Analog Features
1. Defining Macros
On an analog telephone system, telephone system features such as transfer, hold, or speed
dial are usually accessed via key presses or hook flashes. The Link Wireless System
allows these features to be customized using system macros. These features can then be
accessed from all Wireless Telephones by pressing FCN followed by a digit. The macro
definitions are the same for all Wireless Telephones in the system.
For example, suppose your telephone system uses
Link Wireless System, you can assign the transfer function to
Telephone user presses FCN followed by 2, the telephone system will enter the transfer
function. Using macros instead of complicated key presses makes it easier for users to
remember and access features.
Do not program analog features on a digital system.
Macro definitions are made up of combinations of the following characters:
0 to 9 The phone keys numbered 0 to 9
# The phone # key
* The phone * key
FFlash
S Pause 65 milliseconds
The Link Wireless System will accept programming for eleven functions. The maximum
number of key entries for each function is 20.

Open Application Interface
For digital and analog systems with Open Application Interface (OAI) software, the user
may press FCN key sequences to access certain applications. Macro assignments are also
used to assign a function key to initiate an OAI application.
2. Plan Programming
Before programming the features, review the manual for your telephone system to
determine what keystrokes are used to access the desired functions. Then determine
which function key numbers should be assigned to these functions on the Link Wireless
System.
08/11/99 Page 39
SpectraLink Corporation Link 150 M2 Installation and Operation
3. Program Macro Codes
Functions are defined by placing an Administrative Call using the Administrative
Wireless Telephone (registered to Line 2 of MCU 1). Follow these steps to place an
administrative call and define functions.

Speed Dial:
You want FCN 4 to dial 555-1234. The system must access an outside line by dialing 9
and wait for dial tone, then dial the call. Key in the following sequence on the
Administrative Wireless Telephone:
START,FCN,4
9,FCN(pause),FCN(pause),5,5,5,1,2,3,4,END
The number of pause entries depends upon how quickly your telephone system
accesses outside dial tone.
Clear or Erase A Function:
You want to clear FCN 5 from memory. Key in the following:
START,FCN,5,END
Remember that when you change or delete a function using the Administrative Wireless
Telephone, you will change or delete that function on all wireless telephones.

C. Installing the Open Applications Interface
(OAI) Gateway
The OAI Gateway (MOG 400) allows the Link 150 Model 2 to interface with an
application server as shown in the diagram below. This enables third-party applications
to communicate directly with the Link 150, allowing users to retrieve and respond to
information using Wireless Telephones. A single OAI Gateway can be connected to a
Link 150 Master Control Unit (MCU) using an IPC cable (8-conductor cable with RJ-45
connectors).

4. Connect the OAI Gateway to the Application Server
Using a standard 9-pin female D-type connector, connect the serial port on the front panel
of the OAI gateway to the PC, application server, or modem that will be used to interface
with the application.
The OAI Gateway uses the following pins on the connector:
Pin Function
2 Data OAI Receives
3 Data OAI Transmits
5 Ground
If the application is up and running, the RD and SD LEDs on the front panel of the OAI
Gateway should be lit or blinking, indicating that the OAI Gateway is sending and
receiving data to or from the PC.
5. Assign A Function Key to OAI
To access the OAI application, the user presses FCN and an assigned number key.
Follow these steps to assign a function key to inititate the OAI application.

When the OAI Gateway is properly connected to the application server, the LEDs should
look like this:
Power On
Error Off
LED 1
LED 2
LED3/IPC On
LED4/SD On when sending data to server
LED5/RD On when receiving data from server
To test the Wireless Telephones:
• If this is a new installation, continue with Wireless Telephone registration
and PBX programming, and perform the usual voice and coverage tests
when Wireless Telephone installation is complete.
• If you added the OAI Gateway to an existing system, place a call and test
the features on each Wireless Telephone to be sure the system is working
properly.
• Test the application on each Wireless Telephone. The SD and RD LEDs
should be on when the OAI Gateway is communicating with the server (at
least every 30 seconds). Consult your application provider for specific test
procedures.
