Description
This Console allows the simple and efficient handling
of multiple inside and outside calls as well as the perfor-
mance of the other Telecenter functions normally han-
dled by any administrative or display phone. The
following communication resources are included on the
TC4400:
1. Direct Select (DS) keys
These twenty keys each select a line to answer, place,
or transfer a call. Each has a red and a green LED (solid-
state lamp) that show the status of the corresponding line:
Red LED: This relates to Console action: (a) a one-sec-
ond flash rate signals a call; (b) a faster, half-second, flash
rate signals a call on hold; and (c) a steady glow indicates
that the Console is communicating with that line.
Green LED: This relates to non-Console Telecenter
activity: (a) flashing indicates that the line is being called;
and (b) a steady glow indicates that the line is busy (calling
or in communication with the Console or another line).
Only dialing phones activate the green LEDs.
The DS keys can be dedicated to one of three functions.
They will be divided into three groups as follows:
A. Trunk Lines (outside calls): The frost group (starting
at the top left) may have up to ten keys, the recommended
system limit for “AAI” (“Attendant Answer Interconnect”
lines-outside calls directed to the Console).
B. Telecenter Keys (inside calls): These keys serve two
purposes: (1) receiving inside call-ins horn rooms with
speakers and switches or non-dialing phones, plus “Op-
erator” (“0”) calls from dialing phones, and (2) making
inside calls and performing other Telecenter functions.
C. Monitored Extensions: These- keys correspond to
specific Telecenter lines. Although they will typically be
administrative phones, both non-dialing phones and
speaker-and-switch lines can be monitored. The LEDs on
the key show whether a dialing phone is busy or is calling
the Console (“Operator” calls from such a line will come
in on its corresponding key, not a Telecenter Key). The
key can be used to answer a call from the line, to call the
line, or to transfer a call to the line.
2. A 20-Character Alpha-numeric Display
The last four positions contain special prompting
characters on what to do next:
- is the Console’s version of dial tone. This means that
you never have to wait for dial tone, but can begin
dialing a number (or pressing a DS key) immedi-
ately.
BTY means that the number you dialed is busy.
ZHR means that you should press the Transfer, Hold,
or Release key next.
R/number] means you must press either Release or the
DS key with that number. The keys are numbered
l-20, from left to right; for example, I is the left-most
key in the first row, and II is the left-most key in the
second row.
k/number] means you must press the DS key with that
number. This prompt may occur if you attempt to
transfer a trunk to a nonexistent extension. The
system then wants you to go back to the original
trunk before attempting another transfer.
The first 16 characters of the display operate like the
display on a standard Administrative Display Phone. Call-
ins from rooms with switches or non-dialing phones ap-
pear here. These call-ins are listed by their dialing
numbers in the order of their priority. Up to three call-ins
can be listed; as the Console aIlSwets and clears one call,
any additional call-in that is in the queue will come onto
the display.
Characters 13-16 (those just to the left of the four
prompt positions) show the last number called by the
Console (or any other administrative phone that shares
the same display driver). A colon separates this number
from the list of waiting call-ins.
3. A Standard Dial Pad
Use this for dialing numbers or entering other Telecen-
ter functions, just as on a standard tone-dialing phone.
Although all other dialing phones in the Telecenter re-
quire dial tone before they can begin dialing, the Console
has its own direct path to the system and never has to wait.
When dialing to telephone-company lines, however,
actual tones must be sent out. These tones are supplied
by the system rather than the Console, so the tones will
lag behind your pressing of the keys. Even if no tones are
heard for a moment, finish dialing: the system will “catch
up” as soon as a system dialing unit becomes available.

TC4400 Call-Control Console
4. Gray Function Keys
Transfer: This is used to connect two parties
together-typically, a call coming in on a “Trunk” key and
an inside party on a “Monitored Extension.”
If the Console is programmed for ‘Direct Transfer,”
press Transfe+ and then a “Monitored Extension”
key to transfer the caller from the Console to di-
rectly ring the extension.
If the Console is programmed for ‘Pre-Screened
Transfer,” press Transfer to put the caller on hold
while you talk to an inside extension; if the person
there agrees to accept the call, press Release to
complete the transfer.
Hold: This disconnects audio communication but
keeps a party on-line until you come back to him or
transfer him to a Telecenter extension.
Page: If the system includes Director
@
switch panels,
pressing the Console’s Page key will enable you to make
an announcement over all of the speakers switched to the
“A” (green) channel.
Release: Press this to “hang up” on the Console. If the
Console is programmed for “Pre-Screened Transfer,”
pressing Release after pressing Transfer and calling an
inside extension will connect the caller with that exten-
sion and disconnect both of them from the Console
(unless the extension has a speaker but no phone).
5. Audible Signals
Ele+onfc rfng signah (warbling tone) at five-second
intervals announce an outside call or an inside call from
an administrative or hot-line phone. When you are already
busy with a call, a new call may ring only once or repeat-
/I
Some older TC44OO’s have no hook-switch so
edly, depending upon the programming (see “Console
Location Codes” in this manual).
EIecttvnfc ring signals at JO-second intervals are re-
minders of a call on hold.
A sbort beep (single-tone) signals a call-in from call
switches or non-dialing phones. A repeating beep signals
a call from a line programmed for emergency call-ins. ‘l’his
signal is augmented by the letters EMER on the display.
6. Hook Switch
This applies to models shipped after December 1989.
You can press this to “hang-up” instead of pressing the
Refeuse key. If the Console is programmed for “Pre-
Screened Transfer,” pressing the hook switch after press-
ing Transfer and calling an inside extension will connect
the caller with that extension and disconnect both of
them from the Console (unless the extension has only a
speaker).
During normal operation, the hook switch functions
just like the Release key.
7. Tone Volume Control
This is found only on models shipped after December
1989. The tone control is located at the right side of the
Console’s base. Turn this control knob clockwise to in-
crease the volume of tones heard at the Console unit l’hc
tones can be turned down but not off.

Night Answer
This feature works only on systems with special wiring.
This section describes how Night Answer works with the
standard way of providing this wiring. If different wiring
is used, the installer will provide the appropriate operat-
ing instructions.
When the Console is to be left unattended for an
extended period of time (for example, after normal work-
ing hours), the system can be set so that calls to the
Console will be signaled via all of the speakers.

dial #-3-O.
Transferring Calls
The pro&dure used depends upon whether the Con-
sole has been programmed to directly transfer calls or to
pre-screen them.
Notes: 1. The pre-screen option is selected by including
the MAttribute on the Console’s audio line; without this
Attribute, the Console will be set with the direct-transfer
function.
2. When a trunk line is transferred to a speaker, the
trunk line is put on hold by the Console and must be
released by the Console after the conversation has been
completed.
With Direct Transfer
After talking to rhe party, press Il’ransfcr
-, The “___”
prompt will appear on the display. This is
the visual equivalent of dial tone, which means that
the system is waiting for you to specify where you
want to transfer the caller.
If there is a nwnftoredextension key for the desired
extension, press that key. Othenuisc, dial the numtxr (it
is not necessary to use a Telecenter key for this type of
transfer).
- The caller’s line will now ring the extension (or be
directly connected to a speaker). The green LED will
remain on (to show that trunk is still in use), but the
red LED will turn off (because the call has been
tnnsferred from the Console). If the call is not
answered at the extension within the time pro-
grammed at Location &192, it will ring back at the
Console.
To pre-screen a transfer, use the Hold key to place
the caller on hold, then call the extension.
1f that party agrees to accept the call, press Transfer
and then the caller’s DS key.
- The extension will be connected to the caller, and
the red LED will turn off (because rhe Console is
now disconnected from the caller).
If thatparty refuses the caN, press Release to end this
call, then call another extension or press the caller’s DS
key to talk with him again.

will disconnect you from the ringing line and reconnect
you with the caller; then start over by pressing Transfer.)
+ When the extension answers, the display will show
the prompt “Rx,” which means that, after talking to
the extension party, you must press either Release

Transfer, (3) dial the number wanted or press the appro-
priate DS key, then (4) immediately press Release or the
hook switch.
+ The caller will ring the desired phone directly.
Remote Hookflash
What it is: Ifyou receive a call from a CentrexW or PI3X
system and want to transfer this call back to another lint
in that system, you need to send a remote hookllash to
get dial tone from that system. A remote hookflash goes
to the outside system (which has to handle this type of
transfer) without affecting the Telecenter system. After
you get the other system’s dial tone, you can dial the other
party.
To send out a remote ho&flash, press and release
the trunk key of the line with the call from the outside
system.
+ You will hear a confirming beep, typically followed
by dial tone from the outside system.
You can send an additional remote hookflash to the
outside system again if this is needed to complete the
transfer.
Note: RI-1584 (TCIVPnqrammfng-part of XI-1435)
tells how to set the duration of the remote hookflash.
Placing Outside Calls
Press a trunk DS key that is not in use (its LEDs arc out).
--+ The red LED will glow and outside dial tone will
sound.
+ As noted above, the tones will lag behind your
dialing.
Dial the number.
Placing Inside Calls
Once the desired party answers, you can transfer, hold,
or release his line just like an incoming call.
To Call a Monitored Extension: If the line is not busy
(the LEDs are. ofI), .press the key.

Planning
Planning is crucial to any communication system, espe-
cially if it is interconnected. The following are some of the
major issues that must be addressed:
1. Traffic.
2. Equipment supplied by other manufacturers and its
compatibility.
3. Incoming and outgoing call-handling procedures.
4. The provision of features that require additional
wiring or equipment, such as night answer and paging.
5. Mechanical considerations, such as wiring co~ec-
tions, the accessibility of the equipment for subsequent
maintenance and service, and the operating environment.
Refer to the Interconnect Planning Guide &I- 1582 -
part of RI-1435) for help with the general issues.
Equipment
The following equipment is needed to add a Console
to the basic Telecenter IV system:
TC4400: This is the Call-Control Console, which
comes with a Desk Cord, connectors, and labels for the
DS keys. Only one Console may be connected to a system.
TC4410: This expanded-memory CPU is needed to
hold the larger program required by the Console. It also
contains a second EEPROM, for switching between two
different software setups (e.g., calls might be directed to
the Console during the day but to a security station at
night). The switching could be done with a switch or a
logic function. The TC4410 is in all Telecenter IV central
switches manufactured after October 1987.
TC4420: This module interfaces the Console with the
main system. It mounts just above the TC4001 CPU, and
includes a flat cable for interconnecting the interface with
the CPU and MI0 boards. The module has wire-wrap
terminals for the connections to the Console.
TC4430: A 5-volt, 1.2-ampere regulated power supply.
It must be mounted within five feet of the Console.
TC4440: A surface-mount junction box for connecting
the Console to (a) three shielded pairs from the central
system and (b) the 5-volt power supply. It can be mounted
on a wall, a desk, or a single-gang outlet box (but not the
outlet that is used for AC power).
TC4150: The main system uses LLMs (Line-Link Mod-
ules) for some central-system functions and multi-link
phones. The Console requires somewhat fewer lines than
a Key System:
One LLM line is needed for the Console’s audio
connection.
One LLM line is needed for each outside trunk.
These lines should be a contiguous group of Physical
Numbers within the range of 6-255.
Since the Console uses only one line at a time, it
needs only one LLM line for al1 of its system opera-
tions. However, each additional Telecenter key must
be assigned a Physical Number, so that the system
can keep track ofcalls on hold, etc., and the Console
can be given attributes (cf. “Programming,” below).
These Physical Numbers are not associated with any
hardware (no LLM positions). The Physical Numbers
assigned as the attendant’s Telecenter lines must be
one contiguous group within the range of 5-255.
Like any other extensions, Monitored Extensions
with dialing phones must each have their own LLM
line. They must be wired as a contiguous group of
Physical Numbers within the range of 6-255. If non-
dialing phones or speakers are included in this
group, plan carefully to avoid wasting connection
points on the boards.
TC4171: One COA (Central-Oflice Adapter) module is
required for each outside trunk line.
Repeater Amplifiers: One repeater amplifier is re-
quired for each trunk in Canadian installations, and is
strongly recommended for all other installations.
Rauland’s TC4 181 is recommended for most installations.
For Canadian installations, the CSA has approved the
R-TEC VFR1050 (List 2), which can be obtained locally.

TC4400 Call-Control Console
Important: Turn the system power off before doing any
wiring or inserting and removing any modules.
Step 1. Make sure that the CPU module is a TC4410
and is equipped with version 100 or later software (the
version number is marked on the two ROMs, in UZ and
VZ). If necessary, install a new CPU module or chips.
Step 2. While the CPU module is accessed, make sure
that the “EN-DIS” jumper is in the EN (Enable) position.
Step 3. On the Console Interface Module (TC4420),
make sure that the “Norm-Test” jumper is in the Norm
(Normal) position.
Step 4. Remove the bar holding the central unit’s
modules in place. Orient the Interface Module so that its
terminals and their ID markings will be visible through
the rear slot, then slide it into the slot above the CPU.
Step 5. Replace the Telecenter IV’s standard two-re-
ceptacle flat-cable assembly with the three-receptacle flat-
cable assembly supplied with the Interface Module. This
will extend the CPU bus to the Interface Module and the
MIO. Replace the support bar so that all of the modules
are held securely in the TC400 1.
Step 6. Locate the TC4150 (LLM) line to be used for
the Console audio. Remove the line hybrid (Ill) to pre-
vent ring voltage and DC current from reaching, and
possibly damaging, the Console.
Step 7. Connect the T and R terminals of this line to
the right-most T and R terminals of the Interface Module
(see the attached wiring diagram, KM08 12).
Step 8. Connect a twisted pair from an M (+ 12 VDC)
and a Z (0 V) terminal on the MI0 “B” connector to the
left-most M and Z terminals of the Interface Module.
Step 9. Connect the three shielded 22-AWG pairs to
the Interface Module. The shields are not used at this end
and should be taped so that they will not short to any-
thing. The other end of this cable goes to the Console
junction box as shown in Kh30812. These cables may be
up to 1,000 feet long.
At the Junction Box
Step 1. Mount the junction box to a wall, desk, or
single-gang wall box. It must be close enough to an AC
outlet where the power supply can be plugged in and
have its cord reach the connection points in the junction
box. Do not lengthen the power supply’s five-volt cord.
S’iep 2. Bring the three shielded pairs through a hole
in the rear of thkbox.
Step 3. Insert the power-supply cord and the Console’s
desk cord through the oblong hole in the bottom of the
box. Make a loop with these cords within the box and use
the cable ties to secure them in place.
Step 4. Complete the connections in accordance with
KMO812. The connector system in the junction box is
designed to prevent reversed connections, but double-
check them and all of the wires connected to the junction-
box terminals. Pay special attention to the power supply:
reversing or shorting its connections may cause it to fail,
especially if these conditions are prolonged.
Step 5. When the wiring checks out, plug in the power
supply. Proceed to the following section and check out
the Console.
Console Diagnostic Check
These diagnostics are performed with the Console’s
own internal diagnostic program. Therefore, the Console
need not be connected to the Telecenter system for this,
and the system need not be turned on.
Step 1. To enter the diagnostic mode, power up the
Console while pressing the top left (#l) DS key. Release
the key after three seconds. At the left-hand side of the
display, a three-character code will appear. The two digits
following the V’ in the display correspond with the
version of software currently installed in the TC4400.
Note: If your TC4400 software is earlier than version
10.0, and so does not show the software version on the
display, skip to Step 2.
Ifthe Console has a hookswitch and version 10 or later
software, but does not show the software version in the
display at power-up, you may have released the DS key
too soon. Turn the Console off, then try again.
Step 2. Press each DS key.
+ Both LEDs should light and a corresponding capital
letter (A-T) should appear on the display.
Note: If you don’t get the above responses, you may
have released the DS key too soon during the powering-
up. Turn the Console off and try again.
Step 3. Press each function key (Transfer, Hold, Page,
and Release).
-W Pressing any one of these will turn off the DS keys’
LEDs and clear the display. When the Page key is
pressed, a semicolon (“;“) appears on the display;
this is replaced by a c when the key is released. As
each of the other three function keys is press, a
corresponding lower-case letter (a, b, or d) should
appear on the display.
Step 4. Press each dial-pad key.
* Its corresponding number or character should ap-
pear on the display.
Step 5. This diagnostic test may only be performed on
TC4400 Consoles with software version numbers 10 or
above:
Connect a test lead so that it grounds the Console’s
serial output (%S “-refer to schematic KC1541 or dia-
gram KM0812). Every three to four seconds, an exclama-
tion mark (,,!“) will appear on the display, to indicate that
the collision-detection function is working correctly. Re-
move the lead from across the serial communications port
when this test is concluded.
Step 6. When you have finished, exit the diagnostic
function by doing the following:
In Consoles witbout a book switch, remove power
from the Console. For operation, power it up without
depressing any DS keys.
In Consob with a book switch, hang up the handset.
The Console will immediately be in the operational mode.
Console Labels
Step I. Note that the sheet provided consists of four
rows marked with two types of positions: vertical hash
marks (for trunk and Monitored-Extension keys) and
thicker horizontal lines (for “Telecenter” keys). Choose
._ ____ ___ ____~~
._--_..... _____-..--
--___-- - ---~~- --
8 -\

TC4400 Call-Control Console
two sections from these rows to match the functions of
the DS keys.
Step 2. Neatly print the appropriate line number on
each of the selected label positions (press-type or type-
written letters will give good results).
Hint: Do the lettering before cutting out the sections.
To type the label, tape it to a piece of paper before rolling
it into the typewriter.
Step 3. Carefully cut out the sections used and slide
them into the slots at either end of the Console windows
(the clear plastic overlays above the DS keys).
Hint: The strips should be long enough to protrude
slightly from the slots in the Console windows; otherwise,
it may be difftcult to remove the labels for future changes.
Step 4. Leave the unused portions of the label with the
customer for future changes.
Programming
To do the EEPROM (user) programming, you must be
able to use the functions for Attribute programming
(“#99”) and Location-Code programming (“#98”); these
are described in the main system manual, m-1435.
The factory will do some of this programming when the
Interface Module is installed there. Ifyou modify the initial
programming, you may be able to use the Console display;
however, since the rest of the Console will not be opera-
tional until at least some of the programming is done, you
may need to enter the initial programming at an adminis-
trative phone connected to Physical Number 5 (turning
on or resetting the system initializes this line as a display
phone).
In order to do the programming, you need to know:
How many keys-wili be usedfdr trunks (central-of-
fice lines) and the Physical Number of the first (low-
est-numbered) one.
How many keys will be used for the attendant’s
Telecenter lines, and the Physical Number of the first
one.
How many extensions will be monitored, and the
Physical Number of the first one.
The Physical Number of the line used for audio to
the Console. Use the blank Console planning work
sheet at the back of this manual to organize and
record the pertinent data.
Console Location Codes
G4000: Incoming AAI calls normally go to the key phone
or single-line phone whose Physical Number is stored
here. Putting a 0 here tells the system that a TC4400 is
being used.
64004: Listing the Physical Numbers of individual ad-
ministrative phones enables them to pick up calls from
the Console (“#4x”); entering a “0” gives all dialing
phones this ability.
64016: Enter the Physical Number of the first attendant
Telecenter line. When someone dials “0,” the call will be
directed to this key.
64034: Enter the lowest Physical Number of the trunk
lines. Calls from anyone who dials “9” will be routed
there. See the main system manual, KI-1435, for details.
6tZ92: This sets the time (in i/Go-second increments)
before a call transferred by the attendant is returned to
the Console because of no answer.
642222: Attendant Recall: This Location is for key sys-
terns; it should be set to “0” for Console operation.
ti2.24: This must lx set LO the Physical Number of the
Console’s audio line. The audio lint of Ihe TC4400 is
switched from link to link by the control program to
provide the attendant with the requcstcd audio conncc-
tions. This Location can also Ix usctl to allow un:lnswcrcd
calls to ring repeatedly. In the normal mode, a call rings
only once when the attendant is busy with another call;
many users do not want to be disturbed by ringing while
they are handling a call. However, other users prefer
repeated ringing, to prompt someone nearly to answer
the call from an administrative phone (see “Remote An-
swer” in the “Operation” section of this manual).
To set the Console for repeated ringing, add “32768”
to the Physical Number of the Console’s audio line. For
example, if that is Physical Number 9, you would enter
32777 to Location Code 64224.
IX-Key Location Codes
Note: The following Locations, 64226-64232, control
the mapping of the Telecenter IV Physical Numbers onto
the 20 Console DS keys. Each group must begin with a
Physical Number that is less than 256, and the numbers
within each group must be contiguous. If there are no
lines for a particular group, enter a “0” at its Location.
64226: This establishes a mapping of trunks onto the
Console keys and must contain a number based upon the
following equation:
[The Lowest Physical Number of the AAt-Trunk gmrp/
+ /256(Tbe nuntberof trunk keys - I)/.
For an example, see Note 2, on the next page.
The trunk with the highest Physical Number will be
placed on the first key (and the trunk with the lowest
Physical Number on the last key). This reversal is done to
reduce the chances of a “crash” between an incoming and
an outgoing call (see Note 1, below).

Notes: 1. Incoming calls start at 267-1300 (directory

at the opposite end of the group and hunt upward. In this
way, there will be no contention between incoming and
outgoing until all of the trunks arc busy. Incoming calls
progress from the left DS key (7) to the right. ‘1’0 achieve

Numbers (wiring per the TC4 manual) and Physical Num-
bers to the keys (built into the software).
2. The equation for this example is:
Location 64226 = [ 101 + (256 x (6 - l)]
= 10 + [256 x (5)]
= 10 + 1280
= 1290
3. It is recommended that every AAl trunk in your TC4
be represented by a key on the Console. However, if there
are some trunks whose Physical Numbers are not assigned
to keys, calls from them will be sent to the Telecenter keys.
64228: Specify some attendant Telecenter lines. Use
Physical Numbers that do not have equipment associated
with them, since the Console’s attendant Telecenter lines
do not use hardware. Use the following equation for
computing the number to store at 64228:
[Lowest PbysicaINumberJ + [25G x (numberof atten-
dant Teleamter Iines - I)/
Example: For two Telecenter keys at Physical Numbers
201 and 202:
[201] + [256 x (2 - l)]
= 2(X+ 256
= 457
G423O: Enter the block of extensions that are to be
assigned to the “Monitored Extension” DS keys. The op-
erator can then monitor these extensions, or call them by
pressing just one key. Use the equation given in the
preceding section.
64232: This can be used for an optional second block
of Telecenter IV extensions or speakers for which you
want to assign “Monitored Extension” keys.
Here are the factory settings for the above Attributes:
Typical Facto y Settings for the Console and COAs
Setting Attributes
All Telecenter IV phones and speakers have Physical
Numbers (Nodes) that identify the hardware addresses of
associated circuits. For each Physical Number, a set of
“‘Attributes” can be stored and referred to as “N: A: B: Z:”
(“Architectural [Dialing] Number,” “A Attributes,” “B At-
tributes,” and “Zones”). These control the way the system
handles those lines. The main system manual (Kl-1435)
covers the general description and uses of Attributes and
tells how to set them with the #98 and #99 functions.
The following additional information pertains to the
TC4400 Console:
Audio Line (Typical Settings):
N: 777
A: 1 4
B: 12 7 (18~ 2 = interconnect access; 7 = Show call-ins
from Display Driver 1 and last number dialed)
2: (Speaker Zones)
Notes: 1. The Architectural Number (in this example,
777) is used to answer incoming calls to the Console from
another phone (See “Remote Answer” in the operation
section of this manual).
2. The Attribute B:6 may be set to enable “barge in,”
which lets the operator reenter ongoing calls at will.
3. The B:7 Attribute selects the system’s first display
driver. Since the Console cannot use the second driver,
not selecting this Attribute would mean: (a) the Console
would not receive call-ins from switches or non-dialing
phones; and (b) the first 16 characters on its display
would remain blank (i.e., neither call-ins nor the last
number dialed would appear) except during special func-
tions.
4. The B:8 attribute will select the Pre-screening mode
of transferring calls.
5. The A.+14 is a line type used for either the audio line
or an attendant Telecenter line.
Trunk Line (Typical Settings):
N: 999
A: 3 (MI line type)
B: 12 (an inside caller’s phone must be programmed to
call out via a trunk with these settings)
2: (Speaker Zones)
Notes: 1. The number “999” cannot be dialed, because
dialing the first “9” will immediately give an outside lint.
It is not normally desirable to dial individual trunks;
instead, single-digit dialing is normally used.
2.Add theAT8Attribute to send dialed requests for this
trunk, when it is busy, to the trunk with the next higher
Physical Number. B Attributes can be used to enable
certain restrictions on making outside calls (see Kl- 1435).
Attendant Telecenter Line (Typical Settings):
N: (Architectural, or Dialing, Number)
A: 1 4 (Attendant Telecenter-line type)
B: (see RI-1435 for Administrative Attributes)
Z: (Speaker Zones)
Nolo: Set A:8 (hunt bit) to route calls to the next key
when this one is busy.
Monitored Extension Line (Typical Settings):
N: (The extension’s dialing number)
A 1 (Administrative-line type-or an appropriate sct-
ting for single-link phone or speaker)
B: (see RI-1435 for Administrative Attributes)
Z: (Speaker Zones)

Note: Internal DIP switches I and 2 must be set cor-
rectly for operation with Version 10.0 and later Console
software. Incorrectly setting these DIP switches will result
in the following sequence of events when you run the
diagnostics and then attempt to resume normal opera-
tions:
1. The Console diagnostic will still work correctly and
indicate that “all is well.”
2. Resetting the Telecenter system will generate a beep
tone at the Console.
3. After you have reset the TCIV, the message “Telecen-
ter IV” will not appear on the Console display.
4. All Console keystrokes are ignored by the Telecenter
system.
The correct switch settings of the DIP switches are:
SW1
SW3
SW4
Closed Closed Not Used
Open
Step 1. Perform the Console diagnostic described in
the installation section of this manual. If it doesn’t work,
there is some defective hardware that must be ftved before
you can proceed any further.
Step 2. Check the Location-Code entries for the
attendant’s Telecenter lines, trunks, and monitored ex-
tension. Double-check the computation of the numbers
generatedwith the equations in the form of [PHYS + (256
x added lines)]. Make sure that all of the Physical Num-
bers used in these computation fall within the range of
4-255; higher beginning Physical Numbers won’t work.
Step 3. Make sure that Location Codes 64000 and
64222 are set to “0.”
TC4400 Call-Control Console
Troubleshooting
Step 4. To rule out problems with field wiring, bring
the Console and its power supply to the TC4001 and plug
them in for local operation as described in the attached
Console wiring diagram (KMO812). Note that 12-VDC
power and the phone-line T and R connections are
brought to the Interface Module by two discrete wire
pairs, as shown on the diagram.
Step 5. IfSW4 is set incorrectly, the Console will receive
information from the Telecenter system but will not be
able to send any information back to it. The buttons on
the Console will not work, but the diagnostic test will run
properly. Reset the system. If the Console also resets (you
will hear it beep, and “Telecenter lV” will appear in the
Console display), the position of SW4 may be incorrect.
To correct this, make sure that the Console DIP switch 4
is set to the “Open” position.
Step 6. To verify that there is two-way serial communi-
cation between the Console and the TCIV, press any
Console DS key repeatedly. You should hear beeps from
the Console indicating that:
l The TCIV received a repeated keystroke message.
l A response message was sent from the TCN to the
Console.
l The Console correctly interpreted, and responded
to the, message from the TCIV by producing a beep.
If this test works, then look for an error in the program-
ming or setup in the TCIV. If it fails, then either the
Console or its Interface Module may be defective. Test the
Console Interface Module (TC4420) using the procedure
given in the TCIV troubleshooting manual, Kl-1586 (part
of RI-1435).
