From Busy Extensions
To get a call back when any of the busy Extension gets free,
Dial Extension Number
Get engaged tone
Dial #
Keep the handset down.
As soon as the busy Extension gets free, the called and calling Extensions will ring simultaneously.
Note: The above process are true for SLT as well as KTS extensions.
:In case of KTS, Auto Call Back from Junction can also be directly set by dialing #0.
.Auto Call Disconnection .
Selected extensions can be programmed to disconnect Out going Junction call after talking for a set time.
Procedure:Dial #0000
6 NN TT #
Where, NN= Last 2 digits of the Extension Number.
TT= 01 to 99. Time in minutes after which the Junction call is to be disconnected.

.Auto Answer on KTS .
KTS instruments can be converted to Auto Answer mode by pressing the “AUTOANS” key.
In this mode, all internal calls coming to it, will get answered in hands free mode, automatically. When the conversation is over it
will disconnect itself automatically.
.Auto Attendant Operations .
When the PBX is operated in this mode, the Junction caller gets a welcome message.
Thereafter there could be different situations explained below:
-If the Caller dials an extension (other than the Operator) and the extension is busy, the call will ring on the Operator.
At this moment the extension gets an Alert tone.
However, the engaged extension can still pick the call through the following process:
Hold the previous call by FLASH
Dial # 9
FLASH to Hold this call or keep Handset down to disconnect this call
Dial # 9 to retrieve the previous call.
-If the caller dials 0 for Operator & the operator is busy, following would be the options:
The call will ring on the 2nd Operator, if it is made in the PBX. If not then the Operator will get an alert tone. The
Operator can then attend the 2nd call as per the following procedure:
Press HOLD key
Dial # 9
Talk to the 2nd call
Keep the Handset back to disconnect the 2nd call or press HOLD to hold
the 2nd call as well.
Press the DSS key of the 1st call and talk.
Similarly, more than 2 calls can be attended.
Note: If 2 Operators are made and both of them are busy then the incoming call will alert the 1st Operator with a
tone. The 1st operator can then attend to it with the same process as explained above.
.Auto Attendant Message Modes .
In Auto Attendant Mode, voice messages can be recorded in either of the following two Modes:
8Secs Welcome Message + 6 Secs Busy Message + 6 Secs No Answer message
Or
20 Secs Welcome Message / Company Message
These two procedures are explained below under separate headings.
.Auto Attendant Voice message of 8 Secs .
Three types of messages can be recorded for the following 3 conditions:
Welcome Message (8 Secs)
Busy Message (6 Secs)
No Answer Message (6 Secs)
Procedure to record message (SLT/ KTS):

Dial #0000 + 12 M # - now record the message through the Handset.
Here, M = 1 for Welcome Message
2 for Busy Message
3 for No Answer Message
To listen to the recorded message (SLT/ KTS):
Dial #0000 + 13 M # - listen to the message
Options for the case when caller doesn’t dial any number or dials a Wrong Number
When the caller doesn’t dial any number for 5 secs after the DISA message, one of the following 3 options can be set in the
system:
Release the Junction Line
Dial #0000 + 160 #
Transfer the call to Operator
Dial #0000 + 161 #
Transfer the call as defined in Junction Landing in Day/Night Mode
Dial #0000 + 1616 #
Default:The PBX transfers the call to Operator.
Note:When 12M programming is done, the PBX starts working in 8 Secs message mode.
.Auto Attendant Voice message of 20 Secs .
Welcome Message can be made 20 Secs in place of 8 Secs. In this case “Extension Busy Condition” and “Extension No Answer
Condition” are replied by the system in any of the following ways.
Procedure to record messages (SLT/KTS):
To record 20 Secs Welcome Message,
Dial #0000 + 1200 # - now record the Welcome message for 20 secs through the Handset.
To Listen to the 20 Secs Welcome Message (SLT/KTS):,
Dial #0000 + 1300 #
Options for the case when caller doesn’t dial any number or dials a Wrong Number
When the caller doesn’t dial any number for 5 secs after the DISA message, one of the following 3 options can be set in the
system:
Release the Junction Line
Dial #0000 + 160 #
Transfer the call to Operator
Dial #0000 + 161 #
Transfer the call as defined in Junction Landing in Day/Night Mode
Dial #0000 + 1616 #
Default:The PBX transfers the call to Operator.
Note:When 1200 # programming is done, the PBX starts working in 20 Secs message mode.
.Auto Attendant - Playing a Company message while the call is ringing on an extension .
Paradoxically, this option works in “Direct Ring Mode” and not “Auto Attendant Mode”.
This feature is for promoting a company’s message by playing Company Message in place of the Ring Back Tone while the
incoming Junction call is ringing on defined Extension/Operator.
Keep the Junction in Auto Attendant Mode.
Record Auto Attendant message in 20 Seconds message mode.
Dial #0000 + 1670 # (Junction calls will ring on the Consoles while the caller will hear recorded message in place of
the Ring Back Tone)
Dial #0000 + 1676 # (Junction calls will ring on the Extensions that are defined in Direct Ring Mode while the caller
will hear recorded message in place of the Ring Back Tone)
Dial #0000 + 167 # (Feature disabled)
Note: The above programming is true for SLT as well as KTS. However, KTS has an option to do the above through another
process given under the heading ‘KTS Features’ by the name ‘CRBT’.
.Auto Attendant Mode settings .
To set one or all the Junction lines in Auto Attendant mode:
Dial #0000 + 10 # (To set all the Junction lines in Auto Attendant Mode)
Dial #0000 + 10 J # (To set Junction line number J in Auto Attendant Mode)
Where, J = 1,2 or 3 representing 1st, 2nd or 3rd Junction Line.
To shift all Junction Lines from Auto Attendant mode to Normal mode, Dial #0000 + 11 #
Note:In default all the Junction lines are in Direct Ring Mode
:When a junction is set in “Auto Attendant Mode”, “Direct Ring Mode” automatically gets cancelled.
Simultaneous 2 Junction calls in Auto Attendant Mode
The PBX can attend a Junction call at a time. To attend to 2 Junction calls simultaneously an Optional card is to be added to the
PBX.
Following are the options to attend to the Junction calls coming in while the PBX is busy attending a Junction call in Auto Attendant
mode:

Dial #0000 + 1540 # (The 2nd and subsequent caller will not hear anything until the Welcome Message of the 1st call is
over.
Dial #0000 + 1541 # (The 2nd and subsequent callers will ring on Operator or extensions that are defined in Direct
Ring mode.)
Note: The above programming is true for SLT as well as KTS. However, KTS has an option to do the above through another
process given under the heading ‘KTS Features’.
.Barge-In .
Extension number 601 and 602 has the facility to barge into any Extension of Junction Line and over hear or talk in conference.
However, extensions 603 and 604 (if they are KTS instruments) can also Barge into an extension.
From SLT/KTS
Dial # 71 J - To listen to a Junction line (only from 601 and 602)
(J = 1 to 8, the Junction to be barged into)
Dial # 72 XXX - To listen to an Extension,
Where, XXX= Ext Number 603 to 632
From KTS
Besides the above codes, following is additionally possible from KTS:
Pick Up Handset
Press BROAD Key + 3 + Extension Number (For Barging Junction follow the SLT/KTS code)
Disabling Barge-In to particular KTS:
Particular KTS phone can be programmed whereby it cannot be barged in.
Process:
Press ‘Program Key’ twice + Press Left/ Right arrow to enter + Press Up/ Down arrow to select KP Monitor +
Press Left/ Right arrow to Enable/ Disable + Press ‘Store/ Hold’ Key
.Boss Secretary Call .
A BOSS can divert all incoming calls to his Secretary by dialing # 81 XXX from its own extension. Where XXX is the extension
number of the Secretary.
To cancel the feature, Dial # 81 # from the BOSS Extension.
Note:When any extension calls BOSS, the call will go the Secretary.
Secretary extension can hold the call with FLASH and transfer to the BOSS Extension. It is true for internal as well
as Junction calls. Secretary can call the BOSS directly.
.Call Billing / Call Recording & Monitoring / Hotel Management .
The PBX stores approximately 3,000 last Junction calls (dialed out) record in its memory. The output of these records can be
taken on a computer by connecting Serial Port of the PBX to the serial port of PC. Optional PC Management Software has to be
installed in PC, for this purpose.
With PC connectivity, the PBX sends Incoming as well as outgoing call details to the software & software stores the same in PC.
Also the PBX stores upto appox. 3,000 outgoing calls (not incoming) in its memory.
The PC software shows the Incoming calls only if the software is open. If the software is not open then incoming calls get lost.
However, outgoing calls are not lost because whenever software is opened, the PBX sends the missed outgoing calls to the
software.
User can take excel files or print of the calls details with various filters from the software.
Note: If the software is operated without activation key then programming through software, Pass word changeability & other
Management operations cannot be done.
Setting of sensing call maturity
PBX would consider a Junction call as matured in either of the following two ways:
On getting reversal from the Junction Line
or
On Time delay based calculations.
Dial #0000 + 0300 # - To set billing on getting reversal
Dial #0000 + 03TT # - To set billing on Time delay mode.
Where, TT = 01 –99 secs. The billing will start after TT secs of
accessing the Junction line.
Default setting = Billing starts after 5 secs of accessing Junction.
PC Management software
This software provides following features:
Call details
Calls recording / Monitoring
Recording, playing and downloading of Auto Attendant Messages
Hotel Management
Call details
Call charges can be defined in it and Various reports can be taken.
The details include following:
Extension Number

Called number
Junction Number
Date/Time of call
Duration of call
Cost of call
Etc
Calls recording / Monitoring
Conversation of calls made from defined Extensions or on defined Junctions can be recorded in the PC. If many extensions or
Junctions are marked for recording then it will record one conversation at a time. If more than one conversation is on then it will
record the first initiated call.
User can also over hear any conversation through this software from the PC.
Recording, playing and downloading of Auto Attendant Messages
Auto Attendant Messages can be recorded and played through this software or can be down loaded to PBX.
For this operation, Broadcast/Door connector on the PBX has to be used in “Broadcast” mode and is Optional. If this is used then
Door Lock operation cannot be used.
Hotel Management
Feature like Call billing, Check In/out, cash deposit, add deposit, etc are available when operated through this mode of the
software.
To operate Hotel Management, set the PBX in Hotel Management mode as below:
Dial #0000 + 8851 –Te set the PBX in Hotel Management mode.
Dial #0000 + 8850 –Te set the PBX in normal mode. This is the default setting.
.Call Forward .
There are two types of Call Forwarding:
Call Forward Always
An extension can divert all incoming calls to another extension by dialing # 81 XXX from its own extension. Where XXX is the
extension number where calls are to be diverted.
To clear this Call Forward Always feature, Dial # 81 #
This feature can also be programmed from any of the Programming Extensions as explained below:
Dial # 26 NN XXX
Where, XXX= Extension number where Calls are to be forwarded.
NN= The last 2 digits of the original Extension.
Dial # 26 NN # (To clear the feature of NN Extension from any of the programming Extension)
Dial # 26 # (To clear the Call Forward Always feature of all the extensions. To be dialed from any of the
programming Extension)
Call Forward When Busy / No Answer (This can also be used as Round Robin feature)
If calls are to be diverted only when the Extension is busy or is not answering, then,
Dial # 82 XXX from its own extension. XXX= Extension where calls are to be Diverted.
To clear this Call Forward, Dial #82#
This feature can also be programmed from any of the Programming Extensions as explained below:
Dial # 27 NN XXX

Note:In case of KTS there is no need to park a call because it can simply HOLD the call and retrieve by directly pressing
the DSS key of the Junction.
.Checking Extension Number + Date + Time .
To know the extension number of an extension or PBX date or PBX time, do the following:
From SLT extension having CLI Telephone Set
Dial # 62 and keep the handset down.
The extension will ring and its number shall be displayed on the CLI phone. The display may show a 5 digit
number. In that case the last 3 digits would be the Extension number.
Dial # 63 –To see the PBX time
Dial # 66 –To see the PBX date
Dial # 64 –To see the PBX version
From SLT extension having Telephone Set w/o CLI
Dial # 60 –to know the last 2 digits
Hear tones denoting 2 digits of Extension number.
Example:If the extension number is 601, you will hear 10 Tones and then 1 Tone with a gap of 1.5 secs. 10
Tones indicate digit number 0 and 1 Tone indicates digit 1.

Dial # 61–to know the last 3 digits
Hear tones denoting 3 digits of Extension number.
Example:If the extension number is 601, you will hear 6 Tones, 10 Tones and then 1 Tone with a gap of 1.5
secs. 6 Tones indicate digit 6. 10 Tones indicate digit number 0 and 1 Tone indicates digit 1.

.Computer Connectivity –for Call Logging & Call Voice Recording .
following features can be availed when PBX is connected to a Computer & a software is loaded:
PBX Programming (Most of the Programming that can be done from Extension, can also be done through this
software).
Hotel management (Features like Check-In / Check-Out, etc)
Call Details recording
Call Conversation recording (If the PBX is with Door Lock operation then this feature cannot be used.)
The PBX can be connected to a PC by installing optional “PC Interface Card”. PBX is connected to the PC through a “RJ to RS232 Lead” (explained
under the heading “Installation”).
A software is loaded in the PC which can work in the back ground while it is being used for other applications.
The PC then records all the call details and the user can see them with various filter options.
The PBX also has memory to store call details of up to 3,000 calls. This helps in storing the data when the PC is down or not connected.
As soon as the PC is connected, the stored call details get transferred from the PBX to PC & are deleted from the PBX memory.
For recording of Call Voice, connect the ”Broadcast” socket of the PBX to MIC point of the PC (Refer heading “Installation”).
Refer “PC Interface Software” Manual for assigning Extensions / Junctions for conversation recording.
Any number of Junction or Extensions can be programmed for recording. However, PBX will record one call at a time. In case there are more than
1 conversation going on, the PBX will record the first initiated call.
Note: All programing of the PBX can be done from the PC as well as SLT. However, programming through PC is more convenient.

.Junction Call Hold + Transfer + Making multiple calls .
Procedure to transfer a Junction line to another extension
From SLT extension
While talking on a Junction line, FLASH and dial the Extension number while talking on the junction line.
From KTS extension
While talking on a Junction line,
press “Transfer” key + dial the Extension Number
Or
Simply press DSS key of the extension (This option would work in the PBX if set in “Quick Transfer mode”.
Refer “KTS Features” heading)
Now there can be following 4 conditions:
1. When called extension lifts, calling extension can converse and then keep the Handset down. The Junction call will then get
transferred.
2. Called extension lifts but doesn’t want to talk then he may keep the Handset down.
The call will come back to the transferring extension.
3. The called extension is ringing but not lifting the Handset. Keep the Handset down.
The call will ring on the called extension for 25 secs and if not answered it will ring back on the transferring extension.
Now if the Transferring extension is busy, the Junction call will be disconnected by the PBX.
If the user wants to disable this auto call back in case of No Answer while transferring a Junction call,
Dial #0000 + 163 # (Now the Junction call will disconnect if the called extension does pick the call within 25 secs)

To shift back to auto call back mode,
Dial #0000 + 162 #
4. If the called Extension is engaged, the user will hear 2 tones. Now FLASH (press “Transfer” key in case of KTS) to get back to
the Junction line. If FLASH (Transfer in case of KTS) is not done within 10 secs, the Junction line will get connected. This is
the default setting in the PBX.
Alternately the user can change to the following mode:
On dialing an engaged extension user would get engaged tone. During the engaged tone user can FLASH (Press
“Transfer” in case of KTS) and get connected to the Junction line.
Programming:Dial #0000 + 1531 #
To shift back to the default setting:
Dial #0000 + 1530 #
Making two or more Junction calls from SLT
While talking on one Junction line,
FLASH
Dial ## - To park the call
Dial 9 to take another Junction
Dial the required Telephone number
FLASH
Dial ## - To retrieve the first parked call
Similarly, more calls can be made.
Junction dial out and transfer from KTS to SLT
One way is as described above in call hold and transfer. Alternately following is another process:
During internal call talk –press CONF key
Press Junction DSS key
Dial Telephone Number
Press CONF key

The extension can talk on the Junction line
Junction Hold Time Change
Press ‘Program Key’ twice + Press Left/ Right arrow to enter + Press Up/ Down arrow to select ‘CO Hold Time’ +
Press Left/ Right arrow to set the time + Press 'Store/ Hold’ Key
.Junction Dialing Delay Time .
This is the time after the last digit dialed by an extension on Junction Line.It is 5 secs in default.
The PBX assumes call maturity from after the lapse of this time.
The FLASH function to Hold an Incoming Junction call starts working after the lapse of this time.
To change this delay time, Dial #0000 + 03 TT #
Where, TT= 01 to 99 secs. Default value = 05 (5 secs)
.Junction - FLASH .
To send FLASH on Junction line for using Call Waiting on the Telephone Line, do the following:
FLASH while talking on the Junction Line and then Dial # 8
.Junction Grouping .
The Junction lines can be grouped into 2 groups and accessed with 2 different access codes. One group of Junctions are called
“Normal Junctions” and the other ones are called “Special Junctions”. Refer “LCR (Least Call Routing)” for its setting & operations.
Every Junction can be given a separate access code = 1,2,3,4,5,7 or 8. It cannot be 9,0 or 6. If flexible numbering is done then the
first digit of the flexible numbers cannot be used. Refer “LCR (Least Call Routing)” for its setting & operations.
.Junction Ring Assignment .
Junction lines incoming ring can be set in the following 2 modes:
1. Auto Attendant Mode (PBX gives Welcome message. Refer “Auto Attendant Mode Setting” for this.)
2. Direct Ring Mode (Calls land on Operator or defined extensions in Simultaneous Ring mode or Round Robin
Ring mode)
Setting Direct Ring Mode
To set Junctions in Direct Ring mode, following are the programs:
Dial #0000 + 11 # (To set all Junctions in Direct Ring mode)
Dial #0000 + 11 J # (To set selected Junctions in Direct Ring mode)
Here, J= Junction in Direct Ring Mode (1 to 8)
Note:When a junction is set in “Direct Ring Mode”, “Auto Attendant Mode” automatically gets cancelled.
Simultaneous Ring
In this mode, incoming Junction lines ring on one or more Extensions.
Incoming ring of Junction Lines can be programmed separately for Day and Night modes as described below:
Dial #0000 + 3 X J NN 0 #

Here, X= 0 for Day Mode and 1 for Night mode.
J = 1 to 8 (Junction Line no)
NN = Last 2 digits of the Extension No.
This programming can be repeated for one Junction Line and up to 16 Extensions.
One Junction line can be programmed to land on up to 16 Extensions.
Dial #0000 + 3X J # (To disable Ring Assignment of one Junction)
Dial #0000 + 3X J NN 1 # (To disable Ring Assignment of one Junction & Extension)
Default:All the Junction Lines land on Extension number 601 and 602 in Simultaneous Mode.
Round Robin Ring
In this mode, the incoming call lands on one extension. If that extension is busy or doesn’t respond within few rings then the call shifts to another
extension.
Programming:
#0000 + 3X J # This program disables the default ring assignment.
#0000 + 3 X J NN 0 # Here, X= 0 for Day Mode and 1 for Night mode.
J = 1 to 4 (Junction Line no)
NN = Last 2 digits of the 1st Round Robin Extension No.(Not the Flexible Number)
Also note that the first Extension in Round Robin can be 601 to 616 only.
Cannot program Extension 617 to 632 in case of 432S.
# 27 NN XXX Where, XXX= 2nd Extension number of Round Robin Extensions. If flexible numbering is done then
enter the Flexible number. If the Flexible number is say 26 then XXX will be = 26 & not
026.
NN= The last 2 digits of the 1st Extension number (Not the flexible number)
# 27 NN XXX Where, XXX= 3rd Extension number of Round Robin Extensions. If flexible numbering is done then
enter the Flexible number. If the Flexible number is say 26 then XXX will be = 26 & not
026.
NN= The last 2 digits of the 2nd Extension number (Not the flexible number)
# 27 NN XXX Where, XXX= 4th Extension number of Round Robin Extensions. If flexible numbering is done then
enter the Flexible number. If the Flexible number is say 26 then XXX will be = 26 & not
026.
NN= The last 2 digits of the 3rd Extension number (Not the flexible number)
Note:Round Robin Ring Assignment can be set in combination with Simultaneous Ring i.e., some extension would ring in
Simultaneous mode and some in Round Robin mode for the same Junction Line ring.
:To enter many extensions without entering password again and again, following is an example for the procedure:
To assign Extension numbers 601, 602 & 605 to ring for incoming calls on Junction number 2, in Day Mode:
Dial #0000 + 30 + 2 # + 30 2 01 0 # + 30 2 02 0 # + 30 2 05 0 #
Example: To assign Round Robin to 601, 602, 604 and then 603
Dial #0000 + 3 0 1 #
#0000 + 3 0 1 01 0 #
#27 01 602
#27 02 604
#27 04 603
Dial #0000 + 3 0 2 #
#0000 + 3 0 2 01 0 #
Dial #0000 + 3 0 3 #
#0000 + 3 0 3 01 0 #
Options when all assigned extensions are busy
When the extensions assigned for the Junction incoming call are busy, following options can be set:
Dial #0000 + 1880# (The assigned extension when busy, will hear a waiting call beep after every 5 seconds)
This is the default setting.
Dial #0000 + 1881# (The call will land on the first available extension starting from 601, 602, …to … 632)
.Junction - Enable / Disable .
The PBX has auto detect feature whereby it detects whether a Junction line is connected on its Junction port or not.
As we connect a Junction line to the PBX, the corresponding Junction port gets Enabled. As we remove a Junction line, the
corresponding Junction port gets Disabled.
To avoid continuous glow of DSS keys of unused Junction ports, on KTS, assign the DSS keys to Extensions.
.Junction to Junction Forwarding .
Making 2 Junction lines talk to each other while Ext remains out of the conversation.
During conversation with a Junction line - Hook-Flash - # # (To park the Call) –0 –Tel No (who is to be connected to the previous
Junction call) –Hook Flash - # 6 - Now all 3 party can talk to each other but Ext can keep Handset down.
The 2 Junction lines will hear a tone after 80 seconds and if any of them presses * then they can talk for another 90 seconds. Like
this they can keep extending the talk time. If * is not pressed then the calls will disconnect. If they wish to disconnect in between
then any of them need to dial #.
