FCC Requirements
Rauland-Borg’s Model TC4171 (COA Module) conforms to the requirements of the Federal Communica-
tion Commission’s Rules and Regulations, Part 68, which governs the connection of circuitry to protect
the telephone network. The user must be aware of the requirements pertaining to the installation and
the operation of this protective device. The rules are summarized below; the complete current rules will
be in the current copy of the FCC’s Rules.
All of the pertinent rules must be followed.
1. The TC4171 (COA) should only be connected to a standard subscriber line via the proper
coupler installed by the telephone company; it should never be connected to a party line or
coin line.
2. You must give the local telephone company:
a. notice that you want to install an FCC-approved device to their line (similar notice is
required of a final disconnect.)
b. the registration number and the ringer equivalence, which are marked on the
compliance
label, and
C. the connection required for the TC4 171 (COA) - the RJ2 1X, RJ 1 lC, or RJ 11W (see this
manual, KI-1583, the
Interconnect Planning Manual, KI-1582 and wiring diagrams
KM-0714 and KM-0716).
3. Once the telephone company has installed the proper connector, insert the plug coming from
the TC4 171 (COA) wire-wrap terminals.
4. No repairs may be made to the TC4171 (COA) or to the
TC4001 (main central assembly) while
the TC4171 is
connected to the phone line. If any malfunction occurs on this interconnect
device or with the
TC4001, disconnect the TC4171 and replace it with a unit known to be
operating. If the Telecenter equipment is adjudged to be operating properly but the problem
still exists, contact the telephone company. Reconnect the phone system only after determining
that this equipment is not the source of the malfunction.
5. If the TC4171 (CGA) should cause harm to the telephone network, the telephone company is
required, where practicable, to notify you that temporary discontinuance of service may be
required. If advance notice is not practicable, the telephone company is permitted to discon-
tinue its service immediately, provided that such an action is reasonable under the circum-
stances In the case of temporary discontinuance, the telephone company is required to:
a. Promptly notify you of the temporary discontinuance.
b. Give you the opportunity to correct the situation that caused the discontinuance
C. Inform you of your rights to bring a complaint to the FCC pursuant to the procedures set
forth in that agency’s Rules. Copies of the procedure for making a complaint can be
obtained from Rauland-Borg.
6. The telephone company can make changes in its facility, operations, equipment, or procedures,
provided that the changes are reasonably required and are consistent with the FCC’s regulations.
If these changes render the customer’s equipment incompatible or require that it be
modifed, the
telephone company is required to give sufficient advance notice in writing to allow the customer
the opportunity to maintain uninterrupted service.
7. Do not modify, repair, or alter this registered interconnect device, the
TC4171 (COA): any such
actions will void the warranty and could result in discontinuance of service from the telephone
company. If the TC4171 requires service, return it to the Rauland-Borg Corporation.

Perform Initial System Installation and Checkout
Summary: Install the Telecenter IV cabinets in an office environment so that free access is provided to
the front and rear. Ensure proper grounding and power is provided. Verify the system oper-
ates prior to proceeding with the subsequent installation and checkout procedures.
Step 1. Ensure the location for the system is in a normal office environment. That is, there is ade-
quate ventilation and temperatures are in the range of 55
- 80 degrees Farenheit; and, there
are no dangerous vibrations, corrosive fumes, or chemicals.
Step 2.
Ensure technicians can access both the front and rear of each cabinet once the system is
installed. If space is restricted, ensure it is at least sufficient to move the cabinets for access to
the front and rear.
Step 3.
Ensure a grounded power outlet on a fifteen amp circuit breaker is located within six feet
of the cabinet location and that the power cable will not lay in a traffic path. When locating
the power source, consider if the cabinet must be moved to provide access.
Step 4.
Install an AC surge supressor on the power line.
Step 5. Determine how wiring will be run into the space planned for the cabinets (i.e.: where it will
exit the wall, ceiling, or floor and the path to and into the cabinet). For telephone (not
speaker) lines, an interconnect block with 50 pin
Amphenol connectors mounted on ply-
wood is recommended to allow maximum ease of system maintenance and growth.
Step 6. If an interconnect block with connectors is used, ensure the wires from the cable are appro-
priately marked for later connection to the Telecenter Line-Link Modules.
Step 7. Install all Telephones, Speakers, Call Switches, and Displays in accordance with the wiring re-
quirements noted in the applicable drawings and indicated in the
Riser Diagram on the
following page. Refer to ICI-1587 for drawings.

Step 8. Adhere to all applicable electrical and construction codes and run wiring to the space
planned for the cabinet and interconnect block, if one is used. Be sure to mark all cable ends
at the rack area.
Step
9.
Verily that the power ground is in accordance with NFPA 78.
Step 10. Install the cabinet and remove the front and back doors.
Step 11. Before appplying power, ensure the power switch on the TC4001, Central Control Assem-
bly, is in the OFF position (toggle switch is down).

Step 12. Connect the power source and verily the pilot lamp, located by the power switch on the
Central Control Assembly, remains off.
Step 13.
Place the power switch to the ON position (up) and verily the pilot lamp lights. Note:
Other lamps may also be seen to illuminate within the TC4001.
Step 14. Place the power switch in the OFF position and verify all illuminated Iamps go out.
Step 15. Install a modular connector at a convenient place in the cabinet and connect the “T” and “R”
twisted pair to physical number 5 of LLM 0 (TC4150) located in the TC4001 and the Black
and
Yellow twisted pair to the LCD 1 pins on the MI0 (VC7166), as shown in the following

Configure Line-Link Modules
Summary:
Ensure the DIP switch setting on each TC4150 Line-Link Module (LLM) is in accordance with
system requirements.
Equipment required: Small flashlight, six-inch long, small shank
(#l), flat-bladed screwdriver, pliers.
Step 1. Refer to the
Physical Number Layout Planning Worksheet and determine which LLM’s are
required to support the physical numbers noted on the
System Planning Worksheet for
Central Equipment Phone LLM’s.
Step 2. Go
to the front of the system cabinet and locate the LLM’s. LLM 0 is in the Central Control
Assembly (TC4001) and all other LLM’s are immediately below in the expansion chassis.
Step 3. Using the flashlight, peer through the inspection port on the left side of each
LLM and locate
the DIP switch behind the ribbon cable connector. Compare the factory set
DIP switch
settings with the
LLM DIP Switch Settings Table below, keeping the following in mind:
The DIP switch setting provides the system address for the range of physical numbers
supported by a particular LLM.
The LLM number (O-31) is determined by the physical numbers required, not the
number of LLM’s in the system. Refer to the column marked
PHYS. in the table below
for the range of physical number associated with each LLM.
0 means the switch is down.
1 means the switch is up.
Step 4. If setting must be changed, use this figure as a guide to
toggle the switches as necessary. This can be done in one of
two ways: Insert the screwdriver through the inspection
port; or, go to the rear of the cabinet and remove the LLM
after straightening the retaining tabs which hold it in place.
Step 5. On the chassis near the ID strip, mark the LLM with the first
and last physical numbers it supports and remove any con-
flicting factory markings.

Configure Speaker (and Single Link Staff Phone) Control Boards
Step 2.
Step 3.
Step 4.
Summary Ensure the DIP switch on each TC4110 (SC25) and TC4120 (SCC25) Speaker Control
Board is correctly set in accordance with system requirements. Throughout this procedure,
both types of Speaker Control Boards will be referred to as
SC’s.
Step 1. Refer to the
Physical Number Layout Planning Worksheet and determine which SC’s are
required to support the physical numbers noted on the
System Planning Worksheet for
Central Equipment
Phones and Speakers.
If Single Link Staff Phones are used, determine the installation configuration before proceed-
ing. Single Link Staff Stations always include a Speaker but they must not be wired to the
same SC board. Speaker SC’s may or may not be connected to switch panels; therefore, there
are two possible SC configurations when Single Link Staff Phones are used:
One SCC25 for groups of up to 25 Speakers (no switch panels) and,
One SCC25 for groups of up to 25 Single Link Staff Phones.
One SC25 for groups
of up to 25 Speakers (connected to switch panels) and,
One SCC25 for groups of up to 25 Single Link
Staff Phones.
At the back of the system cabinet, locate the SC’s above the Central Control Assembly.
Speaker and Phone SC’s may be identified as follows:
Speaker SC
Sl and S2 terminals are bussed to the MI0 via a shielded cable.
Phone SC
Sl and S2 terminals are bussed to one LLM line via a twisted pair.
Locate the DIP switch next to the ribbon cable connector on the left side of each SC and
compare the switch settings with the table below, keeping the following in mind:
Step 5.
The switch setting provides the system address for the
entire range of physical numbers supported by a particu-
lar board. The SC number (O-19) is determined by the
physical numbers required, not the number of SC’s in the
system. (SC 48 is not normally used.)
If Single Link Staff Phones are used, Control Boards are
mounted in pairs having the same DIP switch setting
except for the rightmost lever (S). This lever must be
Down for a Phone SC and Up for a Speaker SC.
If DIP switch settings must be changed mark the new
setting near the ID strip on each module and remove any
conflicting factory markings.

Install Field Wiring
Summary: Using required wiring, connect the speakers, phones, and other remote cables to the TCIV ac-
cording to the following procedures.
Requirements: Wire wrap tool suitable for 22 gauge modified wrap on .045 posts, plastic cable ties and/or
waxed cable lacing.
Warning:
Do not install interconnect lines to the ‘I’elecenter COAs until instructed.
Step 1. Refer to the Field Wiring Diagram (on the next page) and, while performing the following
steps, keep these points in mind about field wiring:
Dress all wiring down the sides of the cabinet. (Do not run wiring adjacent to power
cables or across boards and connectors.)
When running wires through holes in the chassis, provide adequate insulation to
protect against chaffing. (Do not leave rough edges which may cut or pinch
insulation.)
Use cable ties and/or lacing to keep wiring compact, organized, and flexible.
Provide adequate service loops (1 to 2 inches for each cable and 8-16 inches for
boards) to allow ease of module removal, test, and repair.
On each module, ensure the physical numbers supported are clearly identified.
Wire wrap around each terminal with one wrap of insulation plus five times with
solid wire. (Never wire wrap with stranded wire.)
When using wire piercing connectors insert the correct size wire and twist stranded
shield wires tightly or cover with insulation prior to insertion. (The wrong wire size
will cause intermittent problems and all connectors will have to be replaced.)
Use wires long enough to do the job. (Don’t make unnecessary splices.)
Properly dress shielded cables by stripping only
l/4 to 3/4 inch of shield.
Install lightning protective devices near the point where any wires come into the
building. (Do not rely on the TCIV ground for lightning protection.)
Step 2.
If two completely different programming set ups are required for day and night use, connect
the
EEPROM switch as shown in Drawing KMO896. This is a custom alternative to the
standard day/night function.

NOTE:
While
completing Steps 3 and 4, periodically ensure Telephones and associated Speakers
and Call switches are on the same physical numbers by performing the following test:
A.
B.
Go to the station to be tested and take the phone off-hook for one second.
Blow or talk into the mouthpiece and listen to the headset. If testing a multi-link phone,
there should be feedback, indicating talk voltage is present. A single-link phone should not
provide feedback since they do not receive talk voltage unless relay switched into a commu-
nication path.
C. Verify the correct architectural number (if predetermined) appears on the display as a call-
in. If not predetermined, the factory default is the physical number plus 100.
D. Dial the number from the display phone and listen for room sounds. Then, go to the room
and verily it is getting supervisory beep every 10 to 20 seconds from the speaker.
E.
Pick-up the staff phone: Verify it has talk voltage and the speaker stops beeping. A single
link staff phone won’t get talk voltage if
wired to the wrong circuit.
Note: If this test fails, there is a wiring or programming error. See Programming Section and
verily the following:
Staff phone (single or multi link) with speaker first
(A:7) is specified.
Call-ins are enabled to the display test phone.
Also, refer to the Troubleshooting Section for information on the #73 I/O Diagnostic and
Computer Aided Diagnostics. These tests bypass programming and operate directly off
physical numbers.
Step 3.
Using wire wraps or one of the following options, connect the shielded cable from each
Speaker and Call Switch to the appropriate Speaker Control Board terminals representing
their assigned physical number. Refer to the Physical Numbers Layout Planning
Worksheet and Drawing KMO682.
CTA25
SK2522 Crimp Terminal Adapters for 25 Speakers
22 Gauge Insulation Piercing
Kit for 25 Speakers
Step 4. Using wire wraps or one of the options noted in Step 3, connect the twisted pair from each
Single-Link Telephone to the appropriate Speaker Control Board terminals representing
their assigned physical number. Refer to the Physical Numbers Layout Planning
Worksheet and the appropriate wiring diagram from the following list for stations equipped
with Single-Link Staff Telephones:
KM0686
KM0683
KM0685
Single Link Staff Phone and Speaker
Speaker, Call-Privacy and Priority Switch

Be sure to follow the odd andeven polarity recommendations in the drawings noted
above. To reduce crosstalk in speaker applications, wire the D and E terminal connections of
odd numbered single-link staff phone circuits opposite those of even numberd circuits.

Step 5.
Observing polarity requirements, wire-wrap the twisted pair from each Multi-Link Tele-
phone to
the appropriate Line-Link Module terminals representing their assigned physical
number. Refer to the Physical Numbers Layout Planning Worksheet and the appropriate
wiring diagram from the following list for stations equipped with Multi-Link Telephones:
KM0681
Speaker and Priority Switch
KM0684
DTMF Keypad

Step 6.
Step 7.
Step 8.
Step 9.
Connect the shielded pair from the “C” connector of each TC4200 VFD (Vacuum Fluorescent
Display) and the
"Y" and “B” terminals of each display telephone’s modular connector to the
appropriate LCD 1 or 2 inputs on the
MI0 (Main Input/Output Module in the TC4001).
Refer to the following drawings as appropriate.

If TM432 Graphic Annunciator Modules (GAM) are installed, ensure their power is off and
connect a shielded pair from the appropriate MI0 graphics driver to the first GAM module (in
the first or second module chain) as required to achieve the desired indication (described
below). Refer to Drawing KM0674 for wiring information.
Wire Graphics 1 to the first GAM module in one chain to indicate
Call-ins.
Wire Graphics 2 to a the first GAM module in a second module chain to show lines
in use.
All TM432 GAMs in a chain must be installed in the same location. The recom-
mended installation for the modules and the lamp power supply is in the lamp
cabinet with only a shielded data line to the main equipment rack.
Pulsating indications is another option and requires a special pulse generator,
producing 5 Vdc logic pulses, between ground and the first Graphics Annunciator
Module.
Remove each LLM which supports an Interconnect Line, a VCM, or a Special Page Line.
Then, locate the
“Ul” line hybrid associated with these lines and ensure pin 3 is cut. This
will prevent the 90 Vrms ring signal from damaging the COAs or other modules. This step
should have been performed in the factory for factory installed TC4 160
VCMs and TC417 1
COAs.
Refer to the main wiring diagram KM0674 and verify all other connections (audio control
panels, power amps, system clock, etc.) have been properly made.
Wherever possible, these
are
factory installed. However, large amplifiers may be temporarily removed from a rack for
shipment. If so, they should be mounted and connected to existing wiring.

Install Interconnect Wiring
Summary: Ensure the telephone company wiring is properly installed and tested before connecting any
wiring to the Telecenter. Then, install the interconnect wiring by referring to the general
interconnect drawings on the following page and those developed specifically for this system.
Step 1. If a Key System is installed, ensure it has been properly wired and programmed: Then
connect the twisted pairs for each line to the appropriate LLM terminals representing their
assigned physical number. Refer to the Interconnect Layout Drawing from the Interconnect
Planning Section, the Key
System’s Manual, the Physical Number Layout Worksheet from
the Planning Section, and TCIV Key System Wring
Drawing KM0717.
Note: Use the key system manual for details on wiring and configuring options (e.g.: audible ringing
from which lines to which phones, etc.). KM0717 shows general wiring information for a
standard key system. The
TC440O console has its own manual covering installation, set-up,
and test.
Step 2.
If required, ensure service request is available and applied to terminal CS on the COA
(TC4171) (refer to Drawing KC1475). If not, the keep-alive process may be used to handle
disconnects from DISA trunks.
Step 3.
If ground-start trunks are being used, ensure ground lines have been installed and tested
between the affected COA’s and Central Office or PBX.
Step 4.
Remove each COA and set the jumper to the left of the transformer as required.
PBX Lines 6OO Ohms
Central Office 900 ohms
Step 5. Install
Repeater Amplifier Power Supply Chassis and Modules as detailed on KM0716.
Ensure the power supply is properly grounded to minimize crosstalk and digital noise on the
line. Avoid setting the amplifier gain too high: 6db is typical.
Step 6. Refer to the
Interconnect Layout Drawing and the Interconnect Types figure on the next
page to determine how the interconnect lines should be connected in the system.
Step 7.
Connect the twisted pair from each incoming interconnect line to the CT and CR terminals of
the COA representing their assigned physical numbers. The physical number and directory
number represented by each COA should be marked on the chassis in front of each COA.
Refer to the Physical Numbers Layout Plannin
g Worksheet from the Planning Section and
Drawing KM0716.
Note:
If the Central Office or PBX automatically hunts for a line when contacting the TCIV, wire
the first choice of the C.O. or PBX to the interconnect line with the highest physical number
in the hunt group. Since the TCIV hunts upward, this will reduce the probability of collision
between incoming and outgoing calls.
Step 8.
For “outgoing only” interconnect lines, remove the LLM Ul line hybrid serving the associ-
ated COA module. This prevents the COA from establishing loop current or a service request.
Outside callers will hear ringing but cannot get an answer.
Step
9.
For “incoming only” interconnect lines, refer to the Programming Section and:
Do not program the line for single digit dialing (Location Codes
64016-34).
Assign a non-accessible architectural number (901 if using dial ‘9’ for outside access).
Set the hunt bit (A:8) off on the preceeding line.

Step 10.
Installation
If the key system uses
K4OOE Line Cards, install a 2.2 Meg resistor as shown in the 4OOE
Line Card Modification figure below.
If this is not done, the key phone may continue to ring after callers have hung-up.
The key system times ringing from one burst to the next in order to apply its own
properly timed ringing signal. The timer is typically set to about 10 to
15 seconds al-
though only
5 seconds is sufficient. If the timer period is too long, there will be a
delay in detecting when ringing stops, resulting in a continued ring from the key
system. The 1 Meg resistor decreases the timer period, causing quicker timeout and
ring-stop detection. This delay is most noticeable when using the TCIV built-in Night
Answer to pick-up a call from a key phone.
Step 11. Install a Ring Trip Adapter between the LLM “Ul” line hybrid and its socket on key phone
lines. Refer to drawing
KMO867.
If this is not done, there may be a “ringing in the ear” caused by pressing a line
button to answer an incoming call while holding the handset to the ear or wearing a
headset. This may be objectionable.

Summary: Perform the following steps to ensure proper operation of the interconnect system. See the
Troubleshooting Section for more detailed checks and tests.

Note:
Step 5.
Key Phones Test (Admin A: l--). (Refer to the TCIV and Key System Operations Instructions.)
Using each key phone and each key, obtain TCIV dial tone and verify the appropriate key
phone lamps light. Place a call to each key phone line thru the TCIV and verily audible ring at
the proper instruments and ring flashing on the proper keys of all instruments.
If crosstalk occurs between key phone lines, perform the Line Rebalancing Proce-
dure in the Troubleshooting Section.
Verily the Key Phones each act as operator consoles to perform the following functions:
Answer incoming calls.
Transfer incoming calls.
Break into calls.
Page remote pick-ups.
Night pick-up.
Answer internal dial “0”.
Any key phone key has the following characteristics:
If not associated with a particular trunk, incoming calls go to first available key and the key
clears when the call is transferred. Programming can provide dial “0” for console phone, or
dial various numbers for individual keys.
Outgoing Trunk Test (DISA):
Using an administrative phone, dial the Architectural Number of the interconnect line under
test. If single digit dialing interferes with dialing the architectural number, it may be temporar-
ily defeated (refer to the Programming Section). The CO LED on the TC4171 (COA) module
should glow, indicating the presence of loop current on the Central Office’s (or
PBX’s) side of
the TC4171, and you should get a dial tone from the CO. or PBX remote system. Verify the
ability to dial through and establish communication with any extension of that system. Hold
the connection for 45 seconds, then hang-up and verify a proper disconnect (the CO LED on
the COA goes off).
Incoming Trunk Test (AAI and DIL) :
Have a call placed from the remote system or another CO line. When ringing occurs, the TC
LED on the TC4 171 should glow, indicating that the TC4171 (COA) has responded by
sending loop current to the Telecenter (an external service request will trigger the same
response). As soon as the TCIV answers and gives the dial tone to the DISA trunk, the CO
LED should glow, due to the loop current from the central office (or
PBX).
In the case of DIL or AAI lines, the CO LED will not light and loop current will not occur until
a target phone within the TCIV goes off hook to answer the call.
Once the above tests have been completed and the hardware and wiring are known to be
okay, Telecenter software can be altered to meet system requirements.
(Refer to the Programming manual, Kl-1584.)
