Chapter 1 - Introduction
There are nine universal slots in the MB (slots 0-8). Any kind of peripheral card can be installed
in the universal slot, but a peripheral card that contains a CPU cannot be installed in Slot 8 of
Cabinet 0 (T1,PRIB,BRIB, VOIP,LCOBC,SLIBC). Thereare fixedslots forthePSU, PFTU,MPB, LMU,
RGU3, and RAU.
Power Supply Unit
A Power Supply Unit (PSU) is required in each Cabinet of the Key Service Unit. The PSU converts
commercial AC power (110 - 127 / 220 - 240V AC @ 50-60 Hz) to DC voltages, regulates the
voltages, and provides the appropriate DC voltages to the backplane for distribution to other
system components. Three DC outputs are provided: ±5V DC, +30V DC. LEDs in the PSU front
panel indicate valid outputs as well as the presence of AC input power.
The PSU includes circuitry to charge externally connected 24-volt batteries and controls
operation ofthe batteryback-up circuits.The PSU will provide system operating voltages from
the batteries ifcommercial ACpower fails.The battery back-upcontrol circuitryis incorporated
in the PSU to disconnect the batteries prior to a deep discharge or over-charge.
Ring Generator Unit
The Ring GeneratorUnit(RGU3) providesthering voltageto theSLIB circuitstoring theSLT. The
RGU3 also provides the input to the Message Wait source on the SLIB cards. The output of the
RGU3 is 65V AC, 25 Hz. The RGU3 can support simultaneous ringing for 15 SLTs.
The RGU3 is fitted on the lower right side panel inside the Cabinet.
Main Processing Board
The Main Processing Board (MPB) controls and manages communication between peripheral
interface, supervises all resources in the system, controls gain adjustment of PCM signal,
generates system tone, and manages call processing of the system. The two MPBs available for
use with the XTS are the MPB1 and MPB2. MPB1 is used for a single-cabinet installation only.
MPB1
The MPB1, incorporatesthe system'sRAM, master clock, 2RS-232C ports,and the system'sPCM
voice processing and main micro-processor. The microprocessor is a 32-bit high speed “RISC”
CPU which receives and transmits signaling information from/to other PCBs, controls feature
activation, and PCM time-slot interchange. The MPB has 4 built-in DTMF receivers.
LD1 is the PLLU Synchronization Indicator. This LED will be lit when the PLLU on the MPB has
synchronized with an external clock signal provided to the KSU via a BRI, PRI, or T1 circuit.
LD2-LD9 indicate the operation of the XTS system. LD10-LD13 are reserved for future use.
The MPB1 has the same features as the MPB2 described below, but does not include the
following: Paging Port, MOH Port, Port 5, or Ethernet Jack.
The Real-Time Clock and the 2 MB of SRAM that is associated with the system database are
protected in cases of power loss by a long life-high energy lithium battery. Onboard ROM
contains PCM tone, gain table, etc. needed for digital voice processing.
The 4 MB of flash ROM on the Program Module Unit (PMU) for the MPB1 contains basic system
operating software. A Modem Unit (MODU) can be installed on the MPB, for remote

T1 Interface Board
The T-1Interface Board (T1IB) provides the T-1 (1.544Mbps,24-Voice Channel) digital interface
circuit, control circuitry, and synchronous clock control circuits. DTMF tone detection units can
be installed optionally on the T1IB. The T1IB has 8 LEDs on the front edge of the PCB which
indicates errors of T-1 line, in-use status, and synchronous clock enable status.
Add-on Boards: DTRU4
»
Primary Rate Interface Board
The Primary Rate Interface Board (PRIB) provides one Primary Rate Interface circuit. Each circuit
contains 23 bearer and one data channel (23B+D). When a PRIB card is programmed into the
system, the system interprets all B channels as trunks. Thus, one PRIB which contains 23B+D
circuits provides 23 line appearances to the system. The PRIB card uses 24 time slots when
installed.
The PRIB must usually beused in conjunction with a Channel Service Unit (CSU). Connection is
made viaa DB15 from the PRIB to the CSU.When networking systems that areless than 50 feet
apart, no CSU is required.
The PRIB accepts two DTRU4 boards.
When ordering PRI lines from the telephone company, specify ESF framing and B8ZS line
coding. PRI only supports National ISDN 2 (NI-2). No other standards are supported.

Chapter 1 - Introduction
Basic Rate Interface Board
The Basic Rate Interface Board (BRIB) interface provides four Basic Rate Interface circuits. Each
circuit is comprisedof twobearer (64Kbps each) andone data(16Kbps) channels (2B+D). When
a BRIBis programmed into the system, the systeminterprets all B channels as trunks. Thus,one
BRIB which contains four 2B+D circuits provides eight line appearances to the system. A
maximum of seven BRIBs can be installed into the system (56 B channels).
The BRIB uses the U interface of the BRI standard. Connection to the network is made via RJ45
connectors on the front edge of the board. No CSU is required to connectto the central office.
The BRIB card uses eight time slots when installed.
When ordering BRI lines from the telephone company, specify Capability P as the ordering
code. National ISDN 1 (NI-1) is supported. No other standards are supported.

Introduction 3-3
Chapter 3 - System Installation
Introduction
As with any sophisticated communications device, installation of the XTS requires the care
and forethought of a competent technician. To assure easy servicing and reliable operation,
several factors must be considered when planning the system installation. The installation
consists of these major steps:
Site Preparation
KSU and Power Supply (PS) Installation
PCB Installation
System Wiring
Keyset and Terminal Installation
System Programming and Verification
Installing the XTS is quick and efficient if these installation instructions are followed.
Site Preparation
General Site Considerations
The first step is to locate an acceptable site for the common equipment (KSU, boards, etc.).
When locating a mounting site for the KSU, the following points must be considered.
Wall Mounting -- The KSU is designed for wall mounting and should not be mounted
directly to a masonry or plasterboard wall. It is recommended that a 1/2 inch plywood back
boardbefirmlymountedtothewall,andtheKSUandmaindistributionframebemounted
to the back board.
Rack Mounting -- The KSU is also designed for rack mounting using the optional floor or
cabinet-model rack. If using the rack mounting option, ensure the location for the unit is on a
flat flooring area.
Dedicated Access -- The location must have access to a dedicated 120 Volt AC (±10%), 60 Hz,
single-phase circuit with a circuit breaker or fuse rated at 15 amps. A 3-wire (parallel blade
grounded outlet should be within approximately 6 feet of the lower left rear of the Cabinet 0
mounting.
Grounding -- The location must have access to a good earth ground, such as a metallic cold
water pipe with no non-metallic joints. The ground source should be located as close as
possible to the system.
Ventilation -- The system should be located in an area which is well ventilated with a
recommended temperature range of 68°-78° F and a relative humidity range of 5-60%
(non-condensing).
Distance Parameters -- The system should be located within 25 feet of the telephone
company’s termination point. Also, the location should be within the prescribed station loop
lengths for all keysets and terminals. If existing cabling is to be used, the location of existing
cabling and conduits should be considered.
Page 38
3-4 Site Preparation
Chapter 3 - System Installation
Accessibility -- The location should have adequate accessibility, space, and lighting for
future servicing and should consider the need for future expansion.
Hazard Protection -- The system should be located in an area that is protected from
flooding, flammable materials, excessive dust and vibration.
Interference -- The site should be away from radio transmitting equipment, arc-welding
devices, copying machines and other electrical equipment that are capable of generating
electrical interferences. Operation of this equipment may cause interference; in this case the
user, at their own expense, must take whatever measures may be required to correct the
interference.
Backboard Installation
A wooden backboard is recommended for all installations and must be installed when the
location has masonry or plasterboard walls.
A 1/2-inch plywood material is sufficient for most installations.
The back-board should be mounted at a convenient height, about 3 feet above the floor
and bolted in a number of places to distribute the weight of the system.
Space should be available on the bottom side of the back-board for the MDF cabling and
for optional equipment such as a music source and PFTU, etc.
It is recommended the location of each major item be roughly sketched on the
backboard as an installation layout.
Verify On-Site Equipment
Once the equipment installation site has been identified and a dedicated AC outlet, earth
ground, lighting, and ventilation are available:
1. Verify that all equipment required is on-site and has not been damaged during shipment.
2. Unpack the KSUs to assure there is no shipping damage.
3. Notice that a mounting template is packed with each KSU and this template is required
later in the installation.
4. Check that the type and quantity of boards receive is correct and optional equipment
and a Power Line Surge Protector are on-site.
5. It is not necessary to unpack the individual boards at this time.
If any equipment is damaged or missing, notify the appropriate personnel to
correct the situation.

Chapter 3 - System Installation
KSU Grounding
To ensure proper system operation and for safety purposes, a good earth ground is required.
A metallic cold water pipe usually provides a reliable ground. Carefully check that the pipe
does not contain insulated joints that could isolate the ground path. If insulated joints exist,
another earth ground source must be used or, if allowed, the joints may be bridged.
A #14 insulated AWG or larger copper wire should be used between the ground source and
the KSU. The wire should be kept as short as possible. It is recommended that the wire be no
longer than 25 feet.
Figure 3-5: Earth Cable between KSU and External RGU
Grounding Instructions
1. Remove about 1½ inches of insulation from both ends.
2. Attach one end of the wire to the Ground Lug on the lower left side of the Cabinet 0 by
inserting the wire under the lug screw and tightening the screw securely.
3. Attach the other end of the wire as appropriate to the ground source.
4. Take a DC resistance reading and an AC Volt reading between the chassis ground point
(cold water pipe) and AC ground (third wire AC ground).
The limit is 1V AC and 5 Ohms DC resistance. If a higher reading is obtained, choose a
differentchassisgroundpointandrepeatthisstepuntilasuitablegroundpointisfound.
Grounding to an electrical conduit is NOT considered a good ground!

Chapter 3 - System Installation
Power Line Surge Protection
The AC outlet should be equipped with an additional power line transient surge protection
device. Systems using such devices are more resistant to damage from power line surges
than unprotected systems. Power line surges often occur during switching operations and
especially during violent thunderstorm activity.
Protector Specifications -- Installation of a surge protector meeting these specifications
prevents or minimizes the damage resulting from power line surges.
The Isolation Transformer/Surge Protector shall be a 15 amp self-contained unit that
plugsintoastandardgrounded117VACwalloutlet.
The wall outlet must be designed to accept a 3-prong plug (2 parallel blades and ground
pin).
The protector should be fast operating and capable of protecting transients greater than
200 volts.
It is recommended that the AC outlet be equipped with an isolation transformer/
surge protection device that utilized MOV protection.
Lightning Protection
The system provides secondary protection per UL 1459 Specifications. Primary protection
circuitry is the installers responsibility and should be installed per the National Electric Code
(NEC).
KSU AC Power Plug
1. Before plugging the KSU power cord into the AC source, verify that the Power switch on
the AC/DC front panel is in the OFF position.
2. Plug the KSU power cord into the AC outlet and turn the AC/DC Power switch to ON. The
red/green LED on the PSUs should illuminate.

PCB Handling and General Installation
While it is possible to install and remove system cards with power on, it is not
recommended and could void your warranty.
The system PCBs contain digital circuitry which, while extremely reliable, can be
damaged by exposure to excessive static electricity. When handling PCBs, a grounded
wrist strap should be used to protect the boards from static discharges.
Inserting a PCB
1. Hold the PCB by the injector tabs and, with the components facing right, align the top
and bottom edge of the PCB in the card guides.
2. Slide the card into the system and use the injectors to seat the PCB firmly into the
backplane connector.

Digital CO/PBX Line Interface Boards
Digital CO/PBX line interface boards include the T1 interface board (T1IB), primary rate
interface board (PRIB), basic rate interface board (BRIB), and Voice over internet protocol
(VOIP) card.
T-1 Interface Board
The T-1 Interface Board (T1IB) provides the T-1 (1.544Mbps, 24-Voice Channel) digital
interface circuit, control circuitry, and synchronous clock control circuits. DTMF tone
detection units can be installed optionally on the T1IB. The T1IB has 8 LEDs on the front edge
of the PCB which indicates errors of T-1 line, in-use status, and synchronous clock enable
status.

8 CLOCK Clock Enable/Disable
The T1IB contains 2 switches (SW1 and SW3) and 3 connectors (CN1, CN2 and CN3). The clock
selection switch is used for control synchronous clock. The Line Build-Out switch is controlled
by distance between the XTS Systems and a CSU and SW1 #4 is used for loopback control.
The clock control cable should be connected by a daisy-chain method when more than one
T1IB board is installed. When the clock control cable of the T1IB is connected by daisy-chain
method, the clock selection switch of the first T1IB must be placed in the Enable position and
the other board should be placed in the Disable position. The Line Build-Out switch must be
selected by distance between the XTS System and a CSU and the switch selection as indicated
in the following chart. If the CSU is located near the KSU, all LBO switches should be ON.
The SW1 switch #4 of the Line Build-Out switch is used for LoopBack control. Its switch is used
only for hardware test and must be placed in the ON position for normal operation.

The card ejector tabs are color coded white.
Functionality Description
AutomaticNumberIdentification(ANI)information from the carrier is treated exactly
the same as an inbound ICLID (Caller ID) number. Calls can be routed, placed in the
Unanswered Call Table, sent out to the CTI Module port on a keyset, and run through the
Number To Name Translation Table. The XTS system provides call progress tones in the
same manner as ICLID.
Dialed Number Identification Service (DNIS) information from the carrier is treated
using DID line rules. DNIS calls are routed based on the DID Routing Table.
ANI/DNIS is a combined format, where the system waits for the ANI/DNIS information
from the carrier. When it is received, the system routes the call using ICLID processing. If
this information is not found in the ICLID Route Tables, the DNIS information is compared
to the DID table for a match. The call is then routed based on the DID tables. If a match is
not found on either the ANI or DNIS number, the call is routed based on normal CO line
operation (CO Ringing Assignments).
The following table summarizes the operation of the system.
Table 3-9: Call Routing Criteria
ANI DNIS Operation
N N Calls routed based on normal CO operation (CO Ring Assignments.
N Y Calls routed based on DID tables with DID operation.
Y N Calls routed based on ICLID routing and ICLID operation.
Y* Y Calls routed on ICLID first, if no route is found, the DNIS digits are
*If both ANI and DNIS calls are routed -- the following table summarizes what is displayed at the phone.
The T-1 card accepts ANI/DNIS information in a DTMF format only. Some carriers do
not provide ANI or ANI/DNIS in a DTMF format. Consult your local carrier for available
options.

Primary Rate Interface Board
The Primary Rate Interface Board (PRIB) provides one Primary Rate Interface circuit. Each
circuit contains 23 bearer and one data channel (23B+D). When a PRIB card is programmed
into the XTS system, the system interprets all B channels as trunks. Thus, one PRIB which
contains 23B+D circuits provides 23 line appearances to the XTS system. The PRIB card uses
24 time slots when installed. A feature of Flash 24 programming allows for partial signaling
over T1IBs or PRIBs. This allows you to limit the amount of time slots used per card to four, or
multiples of four up to 20.
The PRIB must usually be used in conjunction with a Channel Service Unit (CSU). Connection
is made via a DB15 from the PRIB to the CSU. When networking systems that are less than
50 feet apart, no CSU is required.

Basic Rate Interface Board
The Basic Rate Interface Board (BRIB) interface provides four Basic Rate Interface circuits. Each
circuit is comprised of two bearer (64Kbps each) and one data (16Kbps) channels (2B+D).
When a BRIB is programmed into the XTS system, the system interprets all B channels as
trunks. Thus, one BRIB which contains four 2B+D circuits provides eight line appearances to
the XTS system.
The BRIB uses the U interface of the BRI standard. Connection to the network is made via RJ45
connectors on the front edge of the board. No CSU device is required to connect to the
central office. The BRIB card uses eight time slots when installed.

Installation
1. Insert the BRIB card(s) into the desired card slot. Up to seven BRIB cards can be installed in
an XTS Cabinet, with a maximum of 18 per system.
If installing a single BRIB, set switch 4 on SW2 to the ON position.
If multiple BRIB cards are being installed, set switch 4 on SW2 to the ON position on
the first card and switch 4 on SW2 on all other cards to the OFF position. Switch 4 on
SW2 determines if the board is the Master Clock source for any digital trunk cards in
the system. Only one Master Source must be enabled in the system.
If installing a BRIB in a system that also has T1 or PRIB boards, use either the T1 or PRIB
card as the Master Clock and set all BRIB SW2 switch 4s to OFF.
2. Refer to ISDN and T1 Clocking (later in this section) for clarification on clocking and

Voice Over the Internet Protocol Card
The Voice Over the Internet Protocol (VOIP) card provides up to eight lines per card (two lines
per installed VOIP module). The VOIP card allows bi-directional voice communication to
other H.323 Revision 2 compatible devices via an IP network such as an internal Local Area
Network (LAN), the Internet, or a Wide Area Network (WAN) using the Ethernet Interface. It
also provides four-digit dialing.
The VoIP card uses Transmission Control Protocol/Internet Protocol (TCP/IP) for packet
delivery over an IP network. Additional standards and protocols are used to provide DTMF,
voice processing, and compression.
The VoIP card can accommodate up to four VoIP modules. Each VoIP module provides
capability for two ports, resulting in a maximum of eight ports when all four modules are
installed.

ISDN and T1 Clocking
When combining BRIB, PRIB, and T1 cards in one KSU, specific settings and cabling are
important for proper clocking. The Phase Lock Loop circuitry within the MPB synchronizes
the clocking from the Central Office to the clocking of the KSU. Popping, crackling, dropped
calls, and one-way transmission are usually attributed to the clocking not being synchronized
correctly.
Set the clock source switch of LMU1 to the up position for T1 clock source chain and to the
down position for PRI/BRI clock source chain.
If using a point-to-point connection (e.g., networking), do not connectclock cable to
a point-to-point circuit.
Examples - Settings and Cabling
The following examples clarify the clocking and cabling for these cards:
Whentheswitchisinthe“up” position, it should beconsidered “ON”.Whentheswitch
is in the “down” position, it should be considered “OFF”.
The cable connection follows the same logic - “up” is clock outside (ON) and “down”
is clockinside (OFF). ON means that clocking is coming fromoutside the KSU and OFF
means that clocking is coming from inside the KSU.
(1) T1IB and (1)PRIB
T1IB PRIB
SW3 On SW2 Off
If both cards in a phone switch are connected to a telephone company clock (not point-topoint T1), put the T1 clock switch in the enable position (UP) to allow it to receive clocking
from the telephone company directly, and do not install the clock cable.
Set the PRIB clock switch in the disable position (OFF), which allows the PRIB to synchronize
its timing off of the backplane (from the T1 clocking). If the T1 is a point-to-point T1, set the
PRIB in the enable position (ON), the T1 in the disable position (OFF), and do not install the
clock cable.

IN of LMU2 to OUT of the BRIB closest to the LMU2
IN from a BRIB in Cabinets 1 or 2 to the next closest BRIB
IN from the last BRIB to OUT of LMU2.

Station Connections
The system can be equipped with any combination of the six station boards; DTIB12, DTIB24,
ETIB, SLIB, SLIBE, and SLIBC. The station interface boards can be installed in any universal card
slot in the Cabinets. It is recommended that slots beginning from slot 0 be used for station
interface boards. Also, since the first port of the DTIB is the database access port (the only
port which enables admin programming by default), it is strongly recommended that a
DTIB12 or DTIB24 be installed in slot 0 and a Digital Keyset w/LCD be connected to the first
port.
Electronic Telephone Interface Board
The Electronic Telephone Interface Board (ETIB) board provides the interface to twelve
electronic telephones or DSS/BLF terminals. The card has one LED indicator for off-hook/in
usestatus.TheETIBcardextractorsarecolorcodedgreen.
There is one 50-pin female amphenol connectors labeled Conn2 located on the front of the
card. This allows the system to be cabled to the main distribution frame (MDF). 25-pair
telephone cabling must be prepared with mating connectors to extend the interface circuits
to the MDF. The cables should be routed through the cable clamps at the bottom of the KSU
to the MDF. These cables are then terminated on industry standard 66M1-50 type
punchdown connector blocks. It is recommended that 66M1-50 split blocks with bridging
clips be used to simplify troubleshooting and to quickly isolate faults.
The only telephone that can be used for database programming is the digital
Executive display telephone.

Adjusting Modem Settings
When using modems connected to SLT ports on the XTS, the gain settings on the SLT port
when using T1 as access to the CO should be set to 0 dB (maximizes modem speed).
CO to SLT Call via a T1 TIE Trunk:
1. Access the specific trunk type above.
2. Hookflash, dial 638 8 on the keypad, then hookflash again.
3. Hang up.

Chapter 3 - System Installation
CO to SLT Call via a T1 Trunk:
1. Access the specific trunk type above.
2. Hookflash, dial 638 6 on the keypad, then hookflash again.
3. Hang up.
SLT to SLT Call:
1. Place an intercom call from 1 SLT to another.
2. Hookflash, dial 638 5 on the keypad, then hookflash again.
3. Hang up.
No adjustment is needed if access to the CO is accomplished by standard loop/ground start
trunk circuits. These trunk types are set to 0 dB by default.
In all cases the maximum modem speed is not as much as if the modem were connected
directly to the CO line.
Testing proves that a baud rate of 33600 can be achieved with SLT-T1 lines. Typical
connection speeds with SLT-T1 are 22700-33600. Typical connection speeds with SLT-Loop/
Ground Start are 17400-23800.
All results were obtained using a 56K U.S. Robotics Sportster modem.

Digital Telephone Interface Board
The Digital Telephone Interface Board (DTIB) provides digital voice and data communications
to/from digital telephones.
An industry standard RJ21 type female connector is mounted on the front edge of the PCB for
connection to the station interfaces.
The DTIB12 and DTIB24 boards provide the interface to 12 and 24 digital telephones
respectively. The card has one LED to indicate off-hook/in use status. The DTIB card extractors
are color coded green.
Cables
There is one 50-pin female amphenol connector labeled CN2 located on the front of the card.
This allows the system to be cabled to the main distribution frame (MDF).
25-pair telephone cabling must be prepared with mating connectors to extend the
interface circuits to the MDF.
Cables should be routed through the cable clamps at the bottom of the KSU to the MDF.
These cables are then terminated on industry standard 66M1-50 type punchdown
connector blocks.
It is recommended that 66M1-50 split blocks with bridging clips be used to simplify
troubleshooting and to quickly isolate faults.
LED1 shows status of the board (ON = in use, OFF = Idle).

Battery Backup Wiring Installation
The system can be equipped to operate from external batteries if local AC power fails. The
backup batteries are connected to the strip connector on the front of the PSU as shown:
PSU
24VDC
Blue
Red
+
Battery Battery
12VDC
Figure 3-32: Battery Back-Up Wiring
+
--
12VDC
The external batteries must provide 24 Volts DC. This is generally accomplished by
connecting two 12-volt batteries per Cabinet in a series arrangement. Operation on batteries
is controlled by the PSU. The PSU provides charging current to the batteries during normal
AC power operation at a maximum of about 1 amp. After connecting the batteries for
backup, ensure that you turn the BATT.SWITCH (located on the faceplate of the PSU) to the
ON position so that when AC power fails the batteries will automatically provide power.
During battery operation, the PSU discontinues battery operation if the AC power is
reapplied or the battery voltage is too low to maintain proper system operation. If a lowbattery cut-off occurs and a new battery must be installed, turn the BATT. SWITCH to the OFF
position, replace the battery, then turn the BATT.SWITCH to the ON position.
The length of time the system operates on the batteries is dependent on several elements
including: battery charge state, condition of the batteries, capacity of the batteries, and the
size of the system (number of station ports).
The following chart gives the approximate backup time for several system sizes and different
battery capacities in ampere-hours.

Electronic Keyset and Terminal Wiring
Wiring from the ETIB to station jack requires two pairs of wire. The first pair provides the
audio or voice path, the second is for signaling or data path. The DATA pair is polarity
sensitive. Reversal does not harm the keyset or system, but the port does not function
properly when reversed. Power is delivered by applying DC voltage to the center tap of the
coupling transformers of each of the 2 pairs.

Wall Mounting the Electronic Key Telephone
All connections to the Electronic Key Telephone are fully modular. To wall mount the
Electronic Key Telephone, it is necessary to have one Wall Mount Kit and one standard-type
jack assembly designed for normal wall hanging applications.
1. Unplug the line cord from the phone. This line cord is not be required and should be
retained as a maintenance replacement item.
2. Lift the plastic number retainer upward and expose the screw underneath. Remove the
screw and the handset tab. Replace it with the handset tab from the Wall Mount Kit.
3. Be careful to position the tab so that the protrusion faces the hookswitch. This allows the
handset to remain secure when the telephone is on the wall. Replace the screw and snap
the number retainer into place.
4. Substitute the short modular cord from the Wall Mount Assembly into the modular
connector vacated by the line cord.
5. Align the wall mount baseplate with holes on the bottom of the telephone. Snap in place.
6. Now match the two key hole slots on the baseplate with the lugs on the 630-A type jack.
Align the modular connector and slide telephone into place. Refer to Figure 3-41 .

Wall Mounting the Digital Key Telephone
To wall mount the Digital Key Telephone, it is necessary to use the Wall Mount bracket and
one standard-type jack assembly designed for normal wall hanging applications. Refer to
Figure 3-41 and Figure 3-42 .
1. Remove the handset from the cradle and locate the plastic retainer in the bottom of the
hook-switch well area. Push the plastic retainer slowly upward until it is free. Locate the
tab on the plastic retainer and make sure the tab is toward you, then place it back into its
holder. Slide the plastic retainer all the way down into its channel. Part of the retainer
remains above its holder to hold the handset secure for the wall mount configuration.
2. Turn the telephone over and unplug the line cord. If the line cord is not plugged into the
wall jack assembly, re-route the line cord through the access channel on the top of the
telephone. If the line cord is plugged into the wall jack assembly, run the line cord
through the hole provided and plug into the connector on the back of the telephone.
3. Line up the hooks on the top and bottom of the wall mount bracket so they can engage
with the slots cut into the bottom of the telephone base. Insert the bottom hooks first.
Slide the mounting bracket slowly downwards until the top tabs slide into the top slots
and snap in place.
