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:

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.

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

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,

is the left-most

key in the first row, and

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.

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.

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

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.

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.

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.

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

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

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

On the Console Interface Module

(TC4420),

make sure that the “Norm-Test” jumper is in the Norm

(Normal) position.

Step

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

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

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

terminal on the MI0 “B” connector to the

left-most

and

terminals of the Interface Module.

Step

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

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

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

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.

Consob

with a book switch, hang up the handset.

The Console will immediately be in the operational mode.

Console Labels

Step

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

____

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

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

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

“0”

for Console operation.

ti2.24:

This must

set

the Physical

Number

of the

Console’s audio line. The audio

lint

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

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).

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-

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

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

1 4

B: 12 7

(18~

2 = interconnect access; 7 = Show call-ins

from Display Driver 1 and last number dialed)

(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.

The

A.+14

is a line type used for either the audio line

or an attendant Telecenter line.

Trunk

Line

(Typical Settings):

999

3 (MI

line type)

B: 12 (an inside caller’s phone must be programmed to

call out via a trunk with these settings)

(Speaker Zones)

Notes:

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):

(Architectural, or Dialing, Number)

A: 1 4 (Attendant Telecenter-line type)

(see RI-1435 for Administrative Attributes)

(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):

(The extension’s dialing number)

1 (Administrative-line type-or an appropriate

sct-

ting for single-link phone or speaker)

B: (see RI-1435 for Administrative Attributes)

(Speaker

Zones)

Note: Internal DIP switches

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

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

Make sure that Location Codes 64000 and

64222 are set to

“0.”

TC4400 Call-Control Console

Troubleshooting

Step

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

is set to the “Open” position.

Step

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:

The TCIV received a repeated keystroke message.

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

RI-1435).

Enhancements

1. Console Identification Codes: The Console sends

and receives ID codes based upon internal DIP switches

and2.

For operation with the Telecenter IV system, these

switches must both be set to

“0.”

2. Hook Switch: The hook switch will send the same

codes to the system as the “Release” key.

Collision Detection: Collision detection is enabled

for the serial port.

Diagnostics

1. Version Number: When the diagnostics are first

entered, the software version number appears at the left

side of the display. The displayed format is

‘Vxx,”

where

‘W’

is a two-digit version number.

2. Cursor Home: When the Console is reset by the

system, the display cursor is set to the left-most position.

3. Collision Detection: The diagnostics program con-

tinually checks the serial-data port for collisions. The

Console sends an ASCII null character to the serial port

once every four seconds. If a collision is detected, an

exclamation mark

(,,!“)

appears at the cursor in the dis-

play. This character is sent to the display each time that a

collision is detected. This condition may be simulated by

shorting the serial-link transmit leads to

-0V.

Diagnostic Exit: You can now exit

fi-om

the diagnos-

tic routine without powering down the Console. Simply

flash the hook switch, and the Console will reset and

immediately resume normal operation.
