DIL 1:N Group
DescriptionUsed to group extensions and/or Extension Groups so that an incoming
CO call comes in on multiple extensions simultaneously.
Up to 96 DIL 1:N Groups can be set up in the system.
Each group can include up to 72 extensions and/or Extension Groups.
Conditions¥ A single extension can be assigned to up to eight different DIL 1:N
Groups at a time.
¥ Delayed Ringing
When an outside call directed to a DIL 1:N Group comes in, all exten-
sions in the group ring immediately by default.
This setting can be changed to delayed ringing or no ring on each DIL
1:N Group member (extension or Extension Group) basis.

Direct Inward Dialing (DID)
DescriptionAllows incoming CO calls to reach a specific extension, a virtual
extension or a group of extensions in the system directly in accor-
dance with the subscriber number sent from the Central Office.
Possible destination of DID calls
¥ Extension user
¥ Extension Group
¥ TAFAS
¥ Remote
¥ Phantom extension
Call Flow
Receives the subscriber number from the Central Office via a DID line.
Modifies the subscriber number according to Ò DID Digit Modification
Parameters.Ó
Determines the destination DN according to ÒDID Dial Registration
Table.Ó
DID Digits Modification Procedures
The System modifies the subscriber number according to the fol-
lowing three parameters.
1. DID Receive Digit
The number of digits effective in the received subscriber number.
2. DID/TIE Delete Digits
The number of digits to be deleted from the beginning of the
digits processed in Step 1.
3. DID/TIE Insert Dial
The dials to be inserted at the beginning of the digits processed in Step 2. 
						

							DFeatures Guide
94 Features Guide
[Example]
DID Receive Digit : 4 (digits)
DID/TIE Delete Digits : 1 (digit)
DID/TIE Insert Dial : 2
The System modifies the received subscriber number Ò4311Ó into
Ò2311Ó as follows:
Processed in Step 1: 4311 ®311
The first digit Ò4Ó was deleted. This results in Ò311.Ó
Processed in Step 2: 311 ®2311
The digit Ò2Ó was added to the beginning of Ò311.Ó This results in
Ò2311.Ó
DID Dial Registration 
Table
The System converts the modified number into the destination DN
according to this table.
[Example]
The System searches for the number Ò2311Ó in the table. When
matching is found, the call rings the corresponding extension or
floating station.
Conditions ¥Hardware Requirements
DID card (KX-T96182) or T-1 Digital Trunk card (KX-T96187) is
required to utilize this feature.
These cards are used for receiving incoming calls only.
¥What if the dialing digits received is not enough to decide the call
destination?
If the number of digits received is less than the number which is pro-
grammed in DID Receive Digit, reorder tone is sent to the caller, or the
call is redirected to the IRNA destination (IRNA feature). This is deter-
mined by System Programming (Section 4.2.7 System - System
Option,  (22) Illegal Number-DID in the Installation Manual).  
¥What if the call destination is not registered?
If the number converted by the DID modification table has no corre-
sponding destinations, reorder tone is sent to the caller, or the call is
redirected to the IRNA destination (IRNA feature). This is determined
by System Programming (Section 4.2.7 System - System Option, (22)
Illegal Number-DID in the Installation Manual).

¥What if the call destination is busy?
If the destination of a DID call is in busy status, the caller may hear a
busy tone or the call is redirected to the IRNA destination. This is
determined by System Programming (Section 4.2.7 System - System
Option, (18) Destination Busy-DID in the Installation Manual).
¥Incoming only
DID trunk is used for receiving incoming calls only.
If the extension user attempts to make a call using a DID trunk (incom-
ing only), the system sends a reorder tone.

Direct Inward System Access (DISA)
DescriptionAllows an outside caller to access specific system features without
operator assistance as if the caller is an extension user in the sys-
tem.
The outside caller can have direct access to features such as: 
¥Placing an intercom callto an extension, modem (for
remote system administration), external pager (for TAFAS)
Phantom extension or Extension Group.
DISA
 built-in Automated Attendant
A DISA caller can access the desired extension simply by
dialing a one-digit code.
¥Calling an outside party.
To control the DISA callerÕs calling ability, one of the following
three Security modes can be assigned on an OGM Group basis.  
Outgoing Message (OGM) can be recorded for the DISA feature.
When a caller reaches the system via DISA line, a pre-recorded
message will greet the caller.  DISA OGMs may be recorded by
the Manager extension or an Operator.
Conditions¥ The following items are required to utilize the DISA feature:
(1) An optional DISA Card (KX-T96191) must be installed.
Up to eight DISA cards can be installed in the system.
(2) The FDN of the OGM Group number should be assigned as the
DIL 1:1 destination.  This assigns the DISA line and the mes-
sage accessed by external callers.
(3) The DISA OGM(s) should be recorded by the Manager or an
Operator.     
(4) The OGM Type should be set to DISA under OGM Group
setting.    
¥DISA Delayed Answer Time
A DISA call is answered after a ringback tone is returned to the caller
after the ÒDISA Delayed Answer TimeÓ expires.  The caller can dial
while hearing the OGM message.
Non Security mode
Trunk Security mode
All Security modeDISA callers can make both outside and
intercom calls without restriction.  
DISA callers are required to enter a pre-
assigned DISA user code to make outside
calls.  
DISA callers are required to enter a pre-
assigned DISA user code to make both
outside and intercom calls. 
						

							Features GuideD
Features Guide 97
¥DISA User Code
This system can store up to 32 programmable DISA user codes with a
COS (Class of Service) level for each.  Each code should be unique.   
¥DISA User Code Entry Failure
If the DISA caller fails to enter the valid DISA user code three times
consecutively, the call will be disconnected.  
¥DISA built-in Automated Attendant Tables
This system can store up to 8 DISA built-in auto attendant number
tables, each includes 10 one-digit numbers.  
¥DISA built-in Automated Attendant  Number
The DISA built-in auto attendant number may be the same as the first
digit of other numbers (extension number, Floating Number, etc.).  To
avoid confusion, the system waits for the second digit for a pre-
programmed amount of time (default: 1 second).  If the second digit is
not dialed before the timer expires, the system assumes that the first
digit is a DISA built-in auto attendant number.
¥Call Forwarding-to CO or TIE Line
If a DISA call is forwarded to an outside party, the caller is not
required to enter a DISA user code if the DISA security mode is ÒNon
SecurityÓ or ÒTrunk Security.Ó
¥CO-to-CO line call duration
The duration of CO-to-CO line calls can be limited by System
Programming.  When a specified period of time (default:10 min)
expires, both lines are disconnected unless the caller prolongs the
duration time, if available.  A warning tone is sent to both parties 15
seconds before the time-limit at 5-second intervals.  
¥ Prolonging the CO-to-CO line call is possible. To prolong his/her call,
the caller should press any dialpad key except 
. The amount of pro-
longing is set by ÒDISA Prolong TimeÓ (0 to 7 minutes). (If this is set
to zero, then prolonging is disabled.) Depending on Ò(13) DISA
Prolong OperationÓ, the call can be prolonged ten timers or  without
limit.
¥ To detect the end of a CO-to-CO line call, CPC Signal Detection and
Tone Detection can be assigned.
¥Tone Detection
The following three ways of Tone Detection are enabled to discon-
nect a CO-to-CO line call by default.
1.  Cyclic Signal Detection:
Used to disconnect the trunk line if the system detects a cyclic 
signal during a CO-to-CO line call by DISA or AGC.
2.  Continuous Signal Detection:
Used to disconnect the trunk line if the system detects a continuous
signal during a CO-to-CO line call by DISA or AGC.
3. Silence Detection:
Used to disconnect the trunk line if the system detects no signal 
during a CO-to-CO line call by DISA or AGC.

¥DISA Call Re-try by Pressing 
The Ò Ó key can be entered during a DISA call. The action taken by
the system depends upon System Programming (System Option 2/4,
(14) Ô Dialing Ò Ó
in DISA CO-to-CO talking , 
). If ÒDisconnect and
make a new callÓ is selected, then the system will disconnect the cur-
rent call and prepare for a new call. Otherwise, the 
will be transmit-
ted down the line to the other party.
¥Intercept Routing
The Floating Number of a DISA OGM Group may be selected as the
destination of Intercept Routing.
¥What if the destination is busy?
If the destination has enabled Call Waiting, then he or she will hear the
Call Waiting tone.  
Otherwise, the caller may hear a busy tone, or the call is redirected to
the IRNA destination. This is determined by System Programming
(Section 4.2.7 System - System Option, Ò(17) Destination Busy-DISAÓ
in the Installation Manual).
¥What if an illegal number is dialed?
The caller may hear a reorder tone, or the call is redirected to the
IRNA destination. This is determined by System Programming (Section
4.2.7 System - System Option, Ò(21) Illegal Number-DISAÓ in the
Installation Manual).
¥How many times does the IRNA destination ring?
This is determined by System Programming (Section 4.2.4 System-
System Timer, ÒCall Forwarding- No Answer TimeÓ in the Installation
Manual).
