CALL FORWARDING - DROPPED CALLS
1. GENERAL
This feature provides a call forwarding function when a PS encounters a Squelch Disconnection (such as PS
moving out of zone, failing to hand over a call, or a sudden power down of the PS) during a two-way connection
with a station/trunk. If this feature is set, the PS can forward the unexpectedly disconnected call to a pre-assigned
forwarding destination, such as a PS, a user of voice mail system, or an analog/D
term station, etc.
Note:This feature is available when C.F.-PS INCOMING INCOMPLETE is already assigned to the PS.
2. OPERATING PROCEDURE
The procedure to set up this feature is shown below:
 Pre-set Dialing
1) Dial the access code to set this feature.
2) Go off-hook and hear the SST (Service Set Tone).
3) Go on-hook.
Overlap Dialing
1) Go off-hook and hear the DT (Dial Tone).
2) Dial the access code to set this feature.
3) Hear the SST.  
4) Go on-hook.
The procedure to cancel this feature is shown below:

3. SERVICE CONDITIONS
1. This feature can be set at each PS, that is already provided with the C.F.-PS INCOMING INCOMPLETE
feature.
2. The forwarding destination of C.F.-PS INCOMING INCOMPLETE is also designated as the destination of
this feature.
3. This feature can be cancelled also by cancelling C.F.-PS INCOMING INCOMPLETE. However, if the
following is set, C.F.-PS INCOMING INCOMPLETE is cancelled, while this feature is maintained:
ASYD command, SYS 1, Index 420, b1 = 1
4. After this feature is once in service, the function of this feature is still maintained, even if a service class of
C.F.-PS INCOMING INCOMPLETE is restricted.
5. When a call is currently being transferred by this feature, the forwarded party (not the forwarding
destination but the party first connected to the Squelch PS) hears the RBT (Ring Back Tone).
6. When this feature has been activated during a two-way call between a PS and a station (including PS), the
station, now being transferred to the forwarding destination, cannot use “TRF” and “HLD” keys (restriction
is imposed).
7. This feature can be applied to:
 a basic two-way connection between a PS and a station (including PS)
 a basic two-way connection between a PS and a trunk (analog, ISDN, CCIS, TLT)
8. The forwarding destination of this feature can be:
a PS
 an analog/Dterm station
 an attendant
 a trunk (COT)
Tie Line
9. When a call terminates just in the middle of “service set” access code dialing (Pre-set Dialing: before going
off-hook), the key operation up until this moment goes all null and void.
10. This feature is not available for a two-way connection between a PS and a (an) ATTCON/DESKCON.
11. When a PS attempts an OG call and it ends up in a Squelch Disconnection before connected to the self-node/
other node trunk, this feature is not activated.
12. If a Squelch Disconnection occurs just during the following state, this feature is not activated:
 A PS is placed on hold during a two-way connection with a station (including PS)
 A station (including PS) is placed on hold during a two-way connection with a PS
13. When a PS encounters a Squelch Disconnection during a two-way connection with a UCD station, this
feature is not available.
14. When this feature is activated and the forwarded party does not answer, the following occurs:
[When CALL FORWARDING - DON’T ANSWER is assigned at the forwarded party] 
						

							CHAPTER 4 NDA-24301
Pag e 1 66
Revision 1.0
- After a certain period of no answer, the call is shifted to the destination of CALL FORWARDING - DON’T
ANSWER.
[When CALL FORWARDING - DON’T ANSWER is not assigned at the forwarded party]
- Recall to the Squelch PS is not made, and the forwarded party continues to ring. 
15. When a call is forwarded by this feature and also is shifted to another destination, the forwarding kind to be
notified to the destination is “C.F.-PS INCOMING INCOMPLETE”.
16. When this feature is activated, the LCD indication on the D
term (forwarded party) is identical to that of
C.F.-PS INCOMING INCOMPLETE.
17. When a Squelch Disconnection occurs simultaneously at both PSs in a two-way connection, this feature is
activated by neither PS.
18. The forwarding kind to be reported to MCI is “C.F.-DON’T  ANSWER”.
19. The assigned data for this feature can be backed up on the HDD/FDD of the PBX.
20. The forwarding destination of this feature is not designated by the ACFS command.
21. This service supports 32 kbps data communication only.
22. Service conditions for 2-line D
term PS are shown below:
a. This service can be assigned to both lines of this type PS.
b. When a Squelch Disconnection occurs, while a line is in a two-way connection and the other line is
placed on hold, this service is applied to the former line only (two-way connection line only).
4. INTERACTIONS
1. When a Squelch Disconnection occurs during a two-way connection between a PS and a station (including
PS), the following ensues according to the assigned service(s):
[When AUTOMATIC ANNOUNCEMENT-PS OUT OF ZONE is assigned to the Squelch PS]
- The party, not the Squelch PS, hears the announcement.
[When this feature is assigned to the Squelch PS]
- The disconnected call is forwarded to the target destination.
[When this feature and AUTOMATIC ANNOUNCEMENT-PS OUT OF ZONE are both assigned to the
Squelch PS]
- The disconnected call is forwarded to the target destination, as this feature takes priority over
AUTOMATIC ANNOUNCEMENT-PS OUT OF ZONE.
[If neither this feature nor AUTOMATIC ANNOUNCEMENT-PS OUT OF ZONE is assigned to the
Squelch PS]
- No measures are taken. The party, not the Squelch PS, hears the ROT (Reorder Tone).
2. A call forwarded by this feature can be answered by  the CALL PICKUP - GROUP feature.
3. A call forwarded by this feature can be answered by  the CALL PICKUP - DIRECT feature.

4. The Call Waiting service is available for the call forwarded by this feature.
5. When a PS moves to a visitor PBX (when roaming) and it encounters a Squelch Disconnection, this feature
is not activated.

None
5. PROGRAMMING
 Entry Procedures
1) ANPD (Assignment of Numbering Plan Data) 
Assign 1st digit code (1st DC) and number of necessary digits (NND) for feature access and 
cancel. 
2) ASPA (Assignment of Special Access Code Data) 
Assign the access code for this feature.
 For service setting 
CI        :  N 
SRV     :  SSCA 
SIDA   :  114 (Call Forwarding - Dropped Calls:  SET) 
 For service cancel 
CI        :  N 
SRV     :  SSCA 
SIDA   :  115 (Call Forwarding - Dropped Calls:  CANCEL) 
Note:When a node has the (node-level) ASPA/ASPAL data and also the network-level  ASPAN
data (for the Fusion service), the node can use both node-level access code and network-
level access code. Also, if both data of ASPA/ASPAL is assigned, ASPAL data takes
priority over ASPA data.
3) ASYD (Assignment of System Data) 
Assign whether to cancel this feature once C.F.-PS INCOMING INCOMPLETE is cancelled.

AUTHORIZATION CODE 
1. GENERAL DESCRIPTION
An AUTHORIZATION CODE is a numerical code dialed by PS users (up to ten digits), which will override the
station CLASS OF SERVICE - INDIVIDUAL [C-15] for facility access restriction. 
2. OPERATING PROCEDURE
Procedure 1
 With a feature Access Code
1) Go off-hook and receive Dial Tone. 
2) Enter the feature Access Code and receive Service Set Tone.
3) Enter the AUTHORIZATION CODE (up to ten digits).
4) Receive Dial Tone. 
5) Enter the number to be called.
Procedure 2 (only for LEAST COST ROUTING [L-5] calls)
 Without a feature Access Code
1) Go off-hook and receive Dial Tone. 
2) Enter the number to be called. 
3) If an AUTHORIZATION CODE is required, the caller will receive Special Dial Tone. 
4) If Special Dial Tone is received, enter the AUTHORIZATION CODE (up to ten digits) or the call is
denied.
Note:The feature access code for AUTHORIZATION CODE will be a maximum of three digits. 
						

							NDA-24301 CHAPTER 4

Revision 1.0
3. SERVICE CONDITIONS
1. The following service feature restriction classes cannot be overrided by using feature.
 SFI=125(PAD LOCK)
 SFI=137(Authorization Code Display Elimination)
2. The followings are conditions of this feature when using My Line (L1) and Sub Line (L2) simultaneously.
(Tow-Line Operation)
 When holding a line, the held line becomes class before changeover, and then after return to original
call, the class becomes changed class.
 When both My Line and Sub Line are held, the class changeover of earliest held line is invalid.
3. The user cannot use “Data Communications-32kbps” using Authorization Code.
4. Visitor PS of “TTC Q.931 protocol Tie Line with PCS Roaming” is not available.
4. PROGRAMMING
Note 1:
To use this feature, basic office data assignment is also required. Refer to Sections 1 and 2 of this chapter.
Note 2:When a user restricts a feature which is not available for PCS system by service feature restriction class
(SFC) before class changeover, the user must also restrict the feature for the service restriction class after
changeover.
Note 3:When using this feature in fusion network, the user must assign the identical Authorization Code to all
nodes.
Note 4:There are two methods of Authorization Code assignment: Full Implementation and the Checksum
methods. In the Full Implementation method, the whole AUTHORIZATION CODE is assigned in the AATC
command and SYS1. Indexes 12, 13, & 14 are assigned 00H. In the Checksum method, partial assignment
for each AUTHORIZATION CODE is assigned in the AATC command. The last one or two digits
(programmable option) are determined by the system according to the data assignments in ASYD, SYSI,
Indexes 12, 13, & 14.
1) ASYD - System Data 1, Index 12. If Index 12 = 0, no Checksum method is used, and Indexes 13
and 14 are ignored, regardless of their assignments. Each Bit in Index 12 directly correlates to a
digit in the AUTHORIZATION CODE assigned in AATC, and will determine the first digit of the
Checksum method. For this example, 26428 has been assigned as the AUTHORIZATION CODE
in AATC. Arbitrarily pick any Bits, 0 - 4, and flag those Bits as data 1.
Note:Bit 0 - 7 may be used when 8-digit AUTHORIZATION CODES are assigned in the AATC
command.

System Data 1, Index 13. Each Bit in Index 13 directly correlates to a digit in the 
AUTHORIZATION CODE assigned in AATC, and will determine the second digit of the 
Checksum method. Pick any Bits 0 - 4, but not the same combination of Bits as picked in Index 12.
System Data 1, Index 14 determines the algorithm used to calculate the last two digits of every 
AUTHORIZATION CODE. (Only decimal numbers may be used in this index, therefore, 
hexadecimal values A to F may not be assigned). System Data 1, Index 14 = X & Y,  where X and 
Y represent any arbitrarily chosen decimal digit 1- 9, and where Y is used to determine the first 
digit and X is used to determine the second digit in the Checksum method. The following data, 
37H, has been used for the example calculation:
Note:If only one digit is to be added via the Checksum method, then Index 13 data will be 00H
and Index 14, b4~b7 are 0.
EXAMPLE CALCULATION:
In AATC, 26428 has been assigned. In System Data 1, Index 12, Bits 0 and 3 were chosen; 26428
2 + 2 = 4. 
The decimal value of Bits 0 - 3 of Index 14 = 7.
4 + N =7. N = 3
.
7 is obtained as any whole number greater than 4 that ends with a 7, the decimal value as 
determined in System Data 1, Index 14, Bits 0 to 3. In AATC, 26428 has been assigned. In System 
Data 1, Index 13, Bits 4 and 1 were chosen; 26428.
8 + 6 = 14.
The decimal value of Index 14, Bits 4 - 7 is 3.
14 + N = 23. N = 9
.
23 is obtained as any whole number greater than 14 that ends with a 3, the decimal value
determined in System Data 1, Index 14, Bits 4 - 7. The AUTHORIZATION CODE will be
26428-39
.
Note:Digits 39 determined by the Checksum method will be unique to the AUTHORIZATION
CODE 26428. In other words, 26428 will not be followed by any digits other than 39.B

ASYD - System Data 1, Index 43, Bit 2, is Service Set Tone sent after AUTHORIZATION CODE.
ASPA access code? 0/1: No/Yes. Assign data “1”.
System Data 1, Index 43, bit 0, is AUTHORIZATION CODE required for DISA? 0/1: required/
not required. Normally assign data “0.”
System Data 1, Index 93, Bit 6. Are the AMND tables Separate or Common for tenants in the 
system? 0/1: Separate/Common. Assign data “0” for separate tables. 
System Data 2, Index 3, Bit 4: Is Account Code used with AUTHORIZATION CODE? 0/1: No/
Ye s .  
System Data 2, Index 3, Bit 5: Type of code? 0/1: AUTHORIZATION CODE/ Forced Account 
Code; assign data “0”.
2) ANPD - Reserve a number level for feature access. Assign for normal (N), hooking (h), and busy 
(b) (if applicable to any feature in this level). Assign NND in accordance with a predetermined 
numbering plan.
3) ASPA - For SRV = SSC (Service Code), SID = 42, assign the access code.

ASPA ACC=45 NND=7 (ACC + Authorization Code)
ASPA - For SRV = LCR (Least Cost Route Selection) / LCRS (Register Sender LCR), if operating 
Procedure 2 is to be used (dialing the AUTHORIZATION CODE after the number dialed), then 
assign data “1” to the AH parameter when programming the LCR(S) access code. Therefore, 
operating Procedure 2 is only available with LEAST-COST ROUTING - 3/6 DIGIT [L-5].
4) ASFC - For stations allowed AUTHORIZATION CODE, assign a Class of Service that allows 
SFI27.
5) AMND - For Tenant 0, assign the Destination Code (DC) as the first digit of all 
AUTHORIZATION CODES and the Maximum Necessary Digits (MND) of the 
AUTHORIZATION CODE. For the above example, a DC of 2 is assigned with an MND of 7. The 
MND value will include the digits added by the Checksum method.
6) AATC - Assign the TN, Digit Code (DC) (the actual code itself), the AUTHORIZATION CODE 
RESTRICTION (ACR) as data “1” and Service Feature Class (SFC) and Route Restriction Class 
(RSC). If ACR is assigned as data 2, Allowed: RSC and SFC parameters are not programmed. 
(SFC parameters are not operational.)
7) LATC - List up all the AUTHORIZATION CODES. This is the simplest way to determine what 
digits have been added to the system with the Checksum method. This is not required if the 
Checksum method is not used.

CALL PARK
1. GENERAL DESCRIPTION
This feature enables a PS user to “Park” a call (C. O. line, Tie line, station, PS) by hooking and dialing a Call
Park Access Code, and by dialing the Call Park retrieval code and a station number that parked the call, the
parked call can easily be retrieved from any station/PS within the system. If the user forgets to retrieve the
parked call, automatic recall function informs the user.
2. OPERATION PROCEDURE
To park a call from PS:
1) Go hooking (press TRF key).
2) Receive a Special Dial Tone.
3) Dial the Call Park a access code.
4) Receive Service Set Tone.
5) Replace the handset.
To retrieve a parked call from the originating station:
 Overlap sending procedure
1) Go off-hook.
2) Receive a Dial Tone.
3) Dial the Call Park local retrieval code (SID=62).
4) The parked call is reconnected.
 Enbloc sending procedure
1) Dial the Call Park local retrieval code (SID=62).
2) Go off-hook.
3) The parked call is reconnected.
To retrieve a parked call from a different station:
 Overlap sending procedure
1) Go off-hook.
2) Receive a Dial Tone.
3) Dial the Call Park remote retrieval code (SID=63) and the number of the station that parked the call.
4) The parked call is reconnected.
 Enbloc sending procedure
When access code operation that using enbloc sending is invalid. (SYS1 INDEX420 bit0=0)
1) Dial the Call Park remote retrieval code (SID=63).
2) Go off-hook.
3) Dial the number of the station that parked the call.
4) The parked call is reconnected. 
						

							NDA-24301 CHAPTER 4
Page 173
Revision 1.0
When access code operation that using enbloc sending is valid. (SYS1 INDEX420 bit 0=1)
1) Dial the Call Park remote retrieval code (SID=63) and the number of the station that parked the call.
2) Go off-hook.
3) The parked call is reconnected.
3. SERVICE CONDITIONS
1. This feature is also available for Sub Line (L2) of a two-line Dterm PS. (By using Two-Line Operation)
2. The parked PS cannot hold a terminal.
3. A PS can park only one call at the same time.
4. A PS cannot park Attendant Console.
5. When Call Park key of Attendant Console key pattern (SYS1 INDEX6 bit 4 ~ bit 6) is valid, and an
Attendant Console is parking a PS, the Attendant Console operator can retrieve the PS by dialing an Access
Code and an Individual Attendant Identification number which is assigned by “Individual Attendant
Access”.
Note:An Attendant Console is not made to recall.
6. When a PS which parks a call does not retrieve the call, the PS is recalled after fixed time which depends
on Automatic Recall Timer (SYS1 INDEX142 default: 500 sec.). When PS parks a call via C. O. line and
then the C. O. side goes on-hook, PBX does not detect the release, however, the COT can be released by
Automatic Recall Timer.
7. This feature can be used all PSs within the system. (Depending on Service Feature Restriction Class)
8. When a parked PS encounters the squelch disconnection, Call Forwarding-Dropped Calls is not available
even though it is set.
9. If a PS which is recalled by Automatic Recall Timer is out of zone, the parked PS user receives Reorder
Tone (ROT).
10. If a parked PS moves on out of zone, the PS is disconnected.
11. As regards condition of “TTC Q.931 a protocol Tie Line with PCS roaming”, as shown below. 
Note 1:When a visitor PS originates a call to station/PS that belongs to the same intra-office, the visitor PS cannot
be parked.
Note 2:When a PS which parked a terminal moves to visitor office, and then the PS is recalled by Automatic Recall
Timer, the terminal receives ROT.×: Possible    –: Impossible
