PBX has various codes for call pick up as detailed below:
Dial 5 or Dial # 9 - To pick up an incoming Junction call ringing on another extension,.
It will pick the calls in following priority
Junction Call being Transferred
Incoming Junction Call ringing
Junction Call on Hold
Door Phone Call
Internal Call
Note- Call Pick up by 5 will work only when there is no flexible numbering is starting by 5. If any flexible numbering is done
which is started with 5 then call Pick up by 5 gets automatically cancelled.
The incoming Junction call telephone number is displayed on the LCD of the CLI phone on which the defined Junction call
rings. This feature will work with Telephones having CLI feature.
When a Junction call is transferred from an extension to another extension, the external telephone number is displayed on
the LCD of the CLI phone. When an extension calls another extension, Extension number is displayed on the LCD of the CLI
phone.
Some CLI Telephones cannot display less than 4 digit numbers. In that case if the PBX extension numbers are less than 4
digits then additional dummy Zeros need to be added by the PBX.
Procedure:
To Enable, Dial #* 0000 + 180 1 #
To Disable, Dial #* 0000 + 180 0 #
Note- If CLI digit addition is enable then if extension is of 2 digits then 2 dummy zeros are added before extension number
and if the extension number is of 3 digits then a zero is added before the extension number.
Default: Disabled
The system senses CLI on Junction lines in DTMF mode or FSK mode.
Procedure: Dial #*0000 + 181 J 0 # for FSK mode
Dial #*0000 + 181 J 1 # for DTMF mode
where J= Junction Number 1, 2 or 3
Default: DTMF mode
. CLI Transmitting Mode (FSK)
.
The PBX generates CLI on Extensions in DTMF mode in default.
An extension user can establish a conference with an extension and a Junction line.
Process: During conversation with a Junction line, Hook-Flash to hold the line.
Then dial * Ext No.
An extension user can establish a conference with 2 Junction Lines :
Process: During conversation with a Junction line - Hook-Flash - ## (To park the Call) –0 –Tel No (who is to
be included in conferencing) –Hook Flash - # * - Now all 3 party can talk to each other.
When Ext keeps the Handset down, the conference ends.

One Door Phone can be connected to the PBX.
Open the back cover of the Door Phone and connect 2 wires on the Terminal block.
These 2 wires are to be connected to any of the Extension port (from 601 to 605) of the PBX.
To define the Extension as the first Door Phone extension, program as below:
Dial #0000 + 80 N#
Where, N = 1 - 5 (Representing the Extension numbers from 601 to 605)
To make the first Door Phone extension as a normal Extension, program as below:
Dial #0000 + 800 #
Door Phone ring assignment
Dial #0000 + 82 N # - To assign extensions to ring when Door Phone calls.
Where, N= 1 –5 (Representing the Extension numbers from 601 to 605)
Repeat the program for up to 3 Extensions maximum except door phone.
Dial #0000 + 82 # - To clear all programmed extensions for Door Phone calls.
When any extension dials # 88, all extensions start ringing. All extensions get connected to the extension who had dialed
the Emergency code. All can talk in conference.
Extension numbers in default are from 601 to 612 and can be changed to 1 digit / 2 digits / 3 digits or 4 digits numbering as
explained under the heading “Flexible Numbering”.
The Flash time of the PBX can be changed as described below:
Dial #* 0000 + Dial 00 L #

Extension numbers can be changed to a desired number of 2 digit, 3 digit or 4 digits from 11 –6999.
The numbering can either be 2digit, 3 digits or 4 digits in any combination.
The flexible number cannot begin with digits 0, 7, 8 and
9. Procedure :
Dial #* 0000 + 9000 + # (This also resets all the flexible numbering of the
PBX) Dial #* 0000 + 9 NN ABCD #
Where, N = Last two digits of the original extension number (This original number always remains the one
that is printed on the MDF even if flexible numbering is
done).
ABCD = The new Extension number. For less than 4 digits, dial # at the end Of Extension
Number. If all the new numbers to be made in sequence then following programming can be done with single program.
This avoids lengthy programming:
Dial #* 0000 + 9000 L K #
Where, L = Length of new numbers –3 digits or 4 digits
K = First digit of the new numbering. If K=2 then the numbering will become 201 (or
2001) Onwards. Then all those Numbers can be changed through the following
programming.
Default: 601,602, to 612
Some or all extensions can be programmed to get Junction Line on lifting the Handset.
To dial internal numbers, dial * on lifting the Handset. You will get internal dial tone of the
PBX. To program an extension to get a free Junction line on lifting handset,
Dial #* 0000 + 20 NN#
Where, NN= last two digits of Extension numbers that is to be programmed for Direct Junction
Access. Dial #* 0000 + 20 # - To convert all Extensions in “Hot Line to Junction” mode
Dial #* 0000 + 21 NN # - To convert NN Extension in normal

In case of dialing out on the Junction Lines, PBX can be configured to work in either of the following 2
modes: Mode Description
Circular When an extension dials 0, the PBX will allot Junction numbers 01.
Next time any Extension dial 0, Junction number 02 will be allotted. Then 03. Then 01.
Sequential When an extension dials 0, the PBX will allot Junction numbers 01.
Next time any Extension dial 0 and if Junction 01 is free then Junction 01 will be allotted.
Junction number 02 will be allotted only when Junction 01 is engaged.
Programming: To program in Circular mode, Dial #* 0000 + 0620 #
To program in Sequential mode, Dial #* 0000 + 0621 #
Every Extension can be programmed to access Junction Line.
The access to each Extension can be different in Day mode and Night
mode. Procedure:
Dial #* 0000 + 70 J NN X # (For Day Mode
access) Dial #* 0000 + 71 J NN X # (For Night
Mode access)
where J = Junction Number (1 to 3)
NN = Last two digits of Original Extension Number (01 to
12) X = 0 to allow Junction access
1 to Disallow Junction
access.
Dial #* 0000 + 70 J X # (To allow/disallow all extensions to access Junction in Day
Mode) Dial #* 0000 + 71 J X # (To allow/disallow all extensions to access Junction in
Night Mode)
Default: All extensions are allowed to access Junction Line in both Day and Night mode.
Junction dialing facility can be controlled Extension wise as below:
Dial #* 0000 + 40 NN L #
where, NN= Last two digits of Extension number.
L = 0 - The Extension can dial only the numbers starting with digits defined in “Allowed Table”
1 - The Extension can dial all numbers.
2 - The Extension can dial all numbers except for ISD numbers.
3 - The Extension can dial all numbers except for STD numbers.
4 - The Extension can dial all numbers except for the numbers starting with digits defined in “Denied
Table-A”
5 - The Extension can dial all numbers except for the numbers starting with digits defined in “Denied
Table-B”
6 - The Extension cannot dial out but can make internal calls.
To give all extensions the same L value: Dial #*0000 + 40 L
# Note: In default: all extensions are in L = 1 mode.
.
To transfer a Junction line to another extension, FLASH and dial the Extension number while talking on the junction line.
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 keep waiting for the Transferring
extension to get free.
4. If the called Extension is engaged, the user will hear 2 tones. Now FLASH to get back to the Junction line. If FLASH
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 and
get connected to the Junction line.
Programming: Dial #* 0000 + 831 #
To shift back to the default setting: Dial #* 0000 + 830 #

. Junction to Junction Forwarding .
This is the time after the last two digits dialed by an extension on Junction
Line. It is 7 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 = 07 (7 secs)
Junction lines incoming ring can be set in the Direct ring modes:
Direct Ring Mode (Calls land on Operator or defined extensions in Simultaneous Ring mode or Round Robin
Ring
mode)
Direct Ring Mode (Simultaneous / Round
Robin) 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 J M 0 + NN1 + NN2…..+NN12 #
J = Junction Number (1-3)
M = 0 for Day mode/ 1 for Night Mode
NN1- NN12= The last two digits of Original extension numbers (01-12) where ring is
required. (Not the flexible number)
Round Robin Ring
In this mode, the incoming Junction 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:
Dial #* 0000 + 3 J M 1 + N1 + N2…..+N12 #
J = Junction Number (1-3)
M = 0 for Day mode/ 1 for Night Mode
N1- N12= The last two digits of Original extension numbers (1-12) where ring is
required. (Not the flexible number)
When all assigned extensions are busy
When the extensions assigned for the Junction incoming call are busy, The assigned extension when busy, will hear a
waiting call beep after every 5 seconds. On flashing ext will get connected to incoming junction call.
Default: All the Junction Lines land on Extension number 601 and 602 in Simultaneous Mode.
To Enable Junction Line, Dial #* 0000 + 060 J #
To Disable Junction Line, Dial #* 0000 + 061 J#
Where, J = Junction Number (1-3)
Note: In default Junction Lines are disable.
Two set of Junction groups can be made. One group can be accessed say by dialing 0 and the other group of Junction
lines by dialing 8.
To allot group 0 to a Junction= Dial #* 0000 + 50 J 0
# To allot group 8 to a Junction= Dial #* 0000 + 50 J
8 # Where, J = Junction Number (1-3)
.
There are 2 types of Junction to Junction Transfer:
1. Incoming Junction Call on Ext to be transferred to another Tel Number/Cell number.
2. Making 2 Junction lines talk to each other while Ext remains out of the conversation.
Incoming Junction Call on Ext to be transferred to another Tel Number/Cell number
Any of the Extension can feed in a Telephone Number or Cell number on its extension whereby the incoming calls on its
extension would get diverted to those numbers.
While talking a tone will be heard after 2 minutes and if is pressed then the call would get extended for another 2
minutes. Like this user can keep extending the talk time. If is not pressed then the calls will disconnect. If user wishes to
disconnect in between then # need to be pressed.
Programming:
Dial from your own Extension #84* Tel No (where calls are to be diverted to) #

In default TT = 09 x 10 = 90 Secs (80 secs talk time and 10 secs Alert Time)
To cancel the feature, dial from your own Extension #84#
Making 2 Junction lines talk to each other while Ext remains out of the conversation.
Process: During conversation with a Junction line - Hook-Flash - #6 (To park the Call) –0 –Tel No (who is to
be connected to the previous Junction call) –Hook Flash - # - Now all 3 party can talk to each other.
but Ext can keep Handset down. The 2 Junction lines will hear a tone after 2 minutes and if any of them
presses * then they can talk for another 2 minutes. 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 #.
The PBX has memory for 48 telephone number that can be dialed from an extension by dialing 2 digits codes. However,
if the ext is given only local dialing facility, then it cannot dial STD number of the memory.
Storing Telephone number in memory:
Dial #*0000 35 CC J NN# Where CC= Memory location (01-48)
J= Junction Number (1-3) or Junction Group ‘0’ or Junction Group ‘8’
NN= Telephone number maximum 16 digits
Note: In case mobile numbers are not dialing properly each time, add 0 or 00 before the number while adding.
