Digital Display - Trunk D-6
D-6 Digital Display - Trunk
General Description
This feature provides the Attendant with a visual indication of incoming and outgoing trunk calls on the
ATTENDANT CONSOLE [A-3]. Trunk identification number, trunk route number, and TENANT [T-12] number,
or Central Office trunk code, are displayed in a numerical readout.
Operating Procedure
The DIGITAL DISPLAY TRUNK is automatically activated whenever the Attendant answers an incoming trunk
call or originates a trunk call.
Service Conditions
1. By pressing the loop key of a call that is in the ATTENDANT CAMP-ON [A-1] mode and using the DEST
key, the Attendant can determine both trunk and telephone number onto which the call is camped.
2. The trunk identification number is displayed on the right side of the ATTENDANT CONSOLE [A-3]
display while TENANT [T-12] and trunk route numbers are simultaneously displayed on the left.
Example 1:
Example 2:
Example 3:
3. If the Trunk Route Number is three digits, the Trunk Identification Number and Trunk Route Number are
displayed.
4. The ATTENDANT CONSOLE [A-3] digital display is limited to a 6-digit numeric display. Since the
Class of Service and trunk routing display is in numeric form, a list must be provided to the Attendant
explaining the restrictions of each Class of Service number and trunk identification number.
5. The DIGITAL DISPLAY - TRUNK feature displays trunk routing information or a 4-digit C.O. line
number. The method used can be optionally selected on a per-trunk group basis.
6. The DIGITAL DISPLAY - TRUNK feature will occur whenever the Attendant answers/originates: 
a.) an incoming C.O. (DID, Bothway, Oneway, FX, WATS) type call.
b.) an incoming TIE Line call. 
c.) an intercept call. 
d.) an outgoing C.O. (DOD, WATS, FX) type call.

Service Conditions (cont’d)
e.) an outgoing TIE Line call or re-enters a held trunk call.
7. An Attendant Console also indicates the C.O. code assigned by System Data at each node in the FCCS
network.
Programming
STEP 1:ASYD - System Data 1, Index 68, Bit 1. Type of INDIVIDUAL TRUNK ACCESS, 0/1: Route and
Trunk Number/Central Office Code.
Note:
If System Data 1, Index 68, Bit 1 is assigned for the Individual Trunk Access to be the ACOC code, then all of the trunks
in all of the routes in the system must have the ACOC code assigned.
STEP 2:ARTD - In CND 25:R/L, if data “0” is assigned, then tenant, route number, and trunk number are
displayed. If data “1” is assigned, then Central Office code is displayed. The ACOC command must be
assigned.
Note:
For display purposes only, Route and Trunk numbers and Central office codes may be used simultaneously in the same
system and are applied on a per-route basis, CDN 25:R/L.
Route and Trunk Number
STEP 3:AT R K - The route and trunk number assigned here provides the system with specific information on
types of routes and their associated trunks, LENs, number of tenants, and any CLASS OF SERVICE-
INDIVIDUAL [C-15] route restriction information.
Central Office Code
STEP 4:ACO C - Each trunk must be assigned a Central Office code.
FCCS Programming 
This data setting describes only the additional or replacement commands used to activate FCCS
services. When used as an FCCS feature, these commands replace the non-network commands (for
example, AAED is replaced by AAEDN). Note that the data setting for FCCS service varies depending
on the node. 
(Note)
STEP 1:ARTDN - In CND 25:R/L, if data “0” is assigned, then tenant, route number, and trunk number are
displayed. If data “1” is assigned, then Central Office code is displayed. The ACOC command must be
assigned.
STEP 2:ACO CN - Each trunk must be assigned a Central Office code.
Note:
When using ASYDL or ASYDN to program an FCCS feature, the basic programming of ASYD is required in addition
to ASYDL or ASYDN.

Direct-In Termination (DIT) D-7
D-7 Direct-In Termination (DIT)
General Description
This feature automatically routes incoming public network calls directly to a pre-selected station without Attendant
assistance. The call can then be processed by the called party. THREE-WAY CALLING [T-2], CALL TRANSFER
[C-10], etc., are handled in the same manner as any normal trunk call.
Operating Procedure
The calling party, outside the system, dials the desired number as usual. However, the call is answered directly at a
predetermined station, bypassing the ATTENDANT CONSOLE [A-3].
Service Conditions
1. Any group(s) of trunks can be used, up to the maximum capacity of the NEAX2400 IMX.
2. Bothway trunks can be used for DIRECT-IN TERMINATION, but incoming only trunks are
recommended.
3. It is not necessary to have special DID trunk connections to the public network as is required with DIRECT
INWARD DIALING [D-8]. However, care should be exercised in the application of Central Office trunk
hunting.
4. If the DIT station is busy, the incoming call is kept ringing until the DIT station becomes idle, or forwarded
to the ATTENDANT CONSOLE [A-3].
5. If there is no answer at a station, the calling party will continuously receive ringback tone. There is no
AUTOMATIC RECALL [A-8] to the Attendant in this case.
6. If the station is assigned to a STATION HUNTING [S-7, 8, 9] group, the incoming call will follow the
hunt group station assignment. If the station is in a CALL FORWARDING [C-2, 3, 5] mode, the incoming
call is connected to the CALL FORWARD target station.
7. This feature is normally used where direct-in service is required on a limited basis. The number of stations
serviced is effectively limited to the number of trunks available for DIRECT-IN TERMINATION.
8. DIRECT-IN TERMINATION is mutually exclusive with NIGHT CONNECTION - FIXED [N-1].
9. DIT trunks can be programmed to terminate elsewhere in the Night mode.
10. When the system is in the Night mode of operation and the DIRECT-IN TERMINATION (DIT) station
is busy, the call will divert to TAS if provided, otherwise, the call will wait on the busy station until it
becomes idle.
11. More than one trunk can be arranged for DIRECT-IN TERMINATION to a particular station line.
12. The DIT call can terminate to a DO NOT DISTURB [D-11D] station.
13. When a DIT call terminates to a restricted station or a station setting CALL FORWARDING - ALL
CALLS [C-5]/BUSY LINE [C-2], or MULTIPLE CALL FORWARDING - ALL CALLS [M-44] / BUSY
LINE [M-24] to a restricted station, the call is routed to the Attendant and terminates at the “ICPT” key
on the ATTENDANT CONSOLE [A-3].
Note:
This service can be activated in system data.
14. After a call is answered, it can be processed by the called station like any normal trunk call.
15. Only the telephone number is available for the destination station assignment when activating this feature
via FCCS.
16. When activating this feature via the FCCS network, this feature is activated by data in the LDM of the
node accommodating the terminated COT. 
						

							NEAX2400 IMX Feature Programming Manual
Page 272ND-70184 (E), Issue 3
D-7 Direct-In Termination (DIT)
Service Conditions (cont’d)
17. When activating this feature via the FCCS network, when the telephone number of the destination station
is deleted:
a.) When the Attendant Console is used, the DIT call terminates to the Attendant Console.
b.) When the Attendant Console is not used, or if the Attendant Console is in night mode, the caller
hears ringback tone.
18. When activating this feature via the FCCS network, a DIT call cannot be queued while all the FCCS links
are busy. Calling party receives ringback tone at that time and after the FCCS link is restored to idle.
19. When activating this feature via the FCCS network, the different destination for C.O. incoming call (ring
down) cannot be set at each tenant group.
Interactions
1. Night DIT service is NIGHT CONNECTION - FIXED [N-1]. The NIGHT CONNECTION - FIXED/
FLEXIBLE [N-1, 2] feature can be used to simulate a DIT application.
2. When using NIGHT CONNECTION - FIXED/FLEXIBLE [N-1, 2], if the station is busy, the call will
divert to TRUNK ANSWER ANY STATION [T-8], if provided. If not provided, the call will queue at the
busy station until it becomes idle.
3. The DIRECT-IN TERMINATION trunk is limited to the following types:
a.) DDD
b.) FX
c.) WATS
d.) CCSA
4. All CALL FORWARDING [C-2, 3, 5] features may be used in conjunction with DIRECT-IN
TERMINATION. In the case of CALL FORWARDING - DON’T ANSWER [C-3], the call must
physically be ringing the DIT station. Call Forwarding is only available from a ground start DIT trunk.
5. STATION HUNTING [S-7, 8, 9] and UNIFORM CALL DISTRIBUTION (UCD) [U-1] may be used
with DIRECT-IN TERMINATION.
Programming
STEP 1:ASYD - System Data 2, Index 11, Bit 7. Will the DIT call to a busy station be routed to the Attendant
Console, or will it queue to the busy station? 0/1: Attendant Console/Queue. Assign on a per-tenant
basis. If the call goes to the Attendant Console, it will ring in on the BUSY or ICPT key.
System Data 1, Index 147. DIT supervisory timer for a busy station. How often will the CPU look at
the Idle/Busy status of the station for rerouting the DIT call to the destination? This index works when
System Data 2, Index 11, Bit 7 is 1.
STEP 2:ARTD - Assign the DIRECT-IN TERMINATION route as shown below:
GROUND START:
RT:  1
1-OSGS :2 2-ONSG :3 3-ISGS :1 4-INSG :3 5-TF :2
6-TCL :1 7-L/T :1 8-RLP :2 15-LSG :1
LOOP START:
RT: 1
1-OSGS :2 2-ONSG :3 3-ISGS :1 4-INSG :3 5-TF :2
6-TCL :1 7-L/T :1 8-RLP :2
STEP 3:AT R K - Assign the LENs, DIT Trunk Route Number, Trunk Number, and Tenant Number.
STEP 4:MBTK - Assign the Make Idle status to the DIT trunk.

Direct-In Termination (DIT) D-7
Programming (cont’d)
STEP 5:ARSC - The DIT target station receiving the call must be assigned a Route Restriction Class (RSC),
allowing the station to be connected to the trunk. The DIT route must be allowed via Route Restriction
Indexes (RRI) 0 & 1.
STEP 6:ACFR - Designate the type of incoming Call Class Indexes (CCI) that require a Transfer Service
Feature Index (TSFI) = 3, DIRECT-IN TERMINATION. The type of CCI must match CDN 6 of the
DIT route. For Night DIT (NIGHT CONNECTION-FIXED [N-1]), allow the CCI a TSFI = 2, NIGHT
CONNECTION-FIXED [N-1].
For Day and Night DIT Service-Same Station
STEP 7:ACSI - Assign the Route Number, Trunk Number, and Connection Service Index = 3 for DIT. Then
assign the Tenant Number and Station Number to serve as the DIT station.
For Day DIT Service
STEP 8:ACSA - Assign the Route Number, Trunk Number, Connection Service Index A = 2 for DIT. Then
assign the Tenant Number and Station Number to serve as the DIT station.
For Day and Night DIT Service-Different Stations
STEP 9:ACSI - Assign the Route Number, Trunk Number, Connection Service Index = 4 for NIGHT
CONNECTION-FIXED (DIT) [N-1]. Then assign the Tenant Number and Station Number to serve as
the DIT station.
Night DIT Only
STEP 10:ASCI - Assign the Route Number, Trunk Number, Connection Service Index = 4 for NIGHT
CONNECTION-FIXED (DIT) [N-1]. Then assign the Tenant Number and Station Number to serve as
the DIT station.
FCCS Programming 
This data setting describes only the additional or replacement commands used to activate FCCS
services. When used as an FCCS feature, these commands replace the non-network commands (for
example, AAED is replaced by AAEDN). Note that the data setting for FCCS service varies depending
on the node. 
(Note 1)
STEP 1:ACSIL - This command must be assigned to the node accommodating the COT. Assign the logical
route number (LGRT), trunk number, and Connection Service Index (CSI) = 3 for DIT activated in
Day and Night mode or 4 for DIT activated in Night mode. Then assign the user group number (UGN)
and Telephone Number to serve as the DIT station.
STEP 2:ACSA L - This command must be assigned to the node accommodating the COT, when setting the DIT
service in day only or different DIT station is used in day and night. Assign the logical route number
(LGRT), trunk number, and Connection Service Index A (CSIA) = 2 for DIT activated in Day mode.
Then assign the User Group Number (UGN) and Telephone Number to serve as the DIT station.
Note 1:
When using ASYDL or ASYDN to program an FCCS feature, the basic programming of ASYD is required in addition
to ASYDL or ASYDN.
Note 2:
The current data should also be set in addition the above-mentioned command:
The command to be set to the node accommodating the COT: ASYD/ARTD/ATRK/MBTK/ARSC/ACFR.

D-8 Direct Inward Dialing (DID)
D-8  Direct Inward Dialing (DID)
General Description
This feature provides for all incoming calls from the public network (except FX or WATS) to reach any system
station without Attendant assistance.
Operating Procedure
The calling party, outside the system, dials the telephone number as usual. However, the call is answered directly at
a predetermined station, bypassing the Attendant.
Service Conditions
1. This feature requires that special DID trunks and telephone numbers be obtained through the local
telephone company.
Note:
Not all telephone company Central Offices are capable of providing this service.
2. If the Central Office numbering plan differs from the user’s station numbering plan, addition or deletion
of digits can be implemented to coincide with the existing numbering plan.
3. This feature is normally used when DIRECT-IN service is desired on an extensive or system-wide basis.
4. DID is also frequently referred to as CENTREX service.
5. If the called station is non-existent, the DID call is automatically routed to the Attendant or another
predesignated station. Calls to invalid numbers can be routed to an Attendant or to a recorded
announcement. See CALL FORWARDING - INTERCEPT/ANNOUNCEMENT [C-25].
6. Wink-start or delay-start signaling is recommended for use in conjunction with this feature.
7. The DID trunk contains a switchable 2db transmission pad that is switched in or out via software control.
8. If DID trunk is immediate start, dial pulse is required.
Interactions
1. Incoming calls have priority over outgoing calls. When a register is assigned as an Outgoing Register
Trunk (ORT), it will also act as an Incoming Register Trunk (IRT) if no IRTs are available. Therefore,
ORTs can act as IRTs, but if IRTs are programmed, they will not act as ORTs.
2. If immediate Start DID trunks are required, Incoming Register Trunks must be programmed in the same
local processor as the DID trunks.
3. CALL FORWARDING [C-2, 3, 5]: When a station has activated a Call Forwarding feature (CALL
FORWARDING - ALL CALLS [C-5], CALL FORWARDING - BUSY LINE [C-2], CALL
FORWARDING - DONT ANSWER [C-3]), the DID call is forwarded to a designated station rather than
to the specific station dialed.
4. STATION HUNTING [S-7, 8, 9]: If the called station is arranged for this feature and is busy, the call
follows any prescribed hunting pattern.
5. CALL WAITING - TERMINATING [C-12]: If the called station has the Call Waiting - Terminating
feature, Call Waiting ringback tone to the calling party is provided when the called station is busy. The
called station hears a 2-burst Call Waiting Tone. Call Waiting is allowed in CDN 46:CW, of ARDT
command.
6. On an incoming call to a busy station, the Call Forwarding feature takes precedence over the Station
Hunting feature, and the Station Hunting feature takes precedence over the Call Waiting feature.
7. The PA-8TLT circuit card provides interface capabilities for eight DID circuits.

Note:
*This can be assigned as data 1, DDD
STEP 3:AT R K - Assign the LENs, DID Trunk Route Number, Trunk Number, and Tenant Number.
Assign the LENs and Incoming Register Trunk Route number (903). The LENs must be for levels 0-3
for any 8RST circuit card. (See Interactions.)
STEP 4:MBTK - Assign the make idle status to the DID and Incoming Register Trunks.
STEP 5:ANPD - Reserve a number level for station access. Assign for Normal (N) and Hooking (H) service.
Number of Necessary Digits (NND) is usually four, and the Busy Lamp Field is activated.
STEP 6:ASPA - Assign the access code as assigned in ANPD above. Type of Service, SRV = STN (Station).
Four is the number of digits usually required.
STEP 7:ARSC - The DID station receiving the call must be assigned a Route Restriction Class (RSC) that will
allow the station to be connected to the incoming DID route. The DID route must be allowed via Route
Restriction Indexes (RRI) 0 & 1.
FCCS Programming 
This data setting describes only the additional or replacement commands used to activate FCCS
services. When used as an FCCS feature, these commands replace the non-network commands (for
example, AAED is replaced by AAEDN). Note that the data setting for FCCS service varies depending
on the node.
 (Note)
STEP 1:ARTDN - Assign the DIRECT INWARD DIALING route as shown below:
RT: 1
3-ISGS :7 4-INSG :3 5-TF :2 6-TCL :5 7-L/T :1
8-RLP:215-LSG:828-ANS:146-CW:1
STEP 2:ANPDN - Reserve a number level for station access. Assign for Normal (N) and Hooking (H) service.
Number of Necessary Digits (NND) is usually four, and the Busy Lamp Field is activated.
STEP 3:ASPAN - Assign the access code as assigned in ANPD above. Type of Service, SRV=TELN. Four is
the number of digits usually required.
STEP 4:ARSCN - The DID station receiving the call must be assigned a Route Restriction Class (RSC) that
will allow the station to be connected to the incoming DID route. The DID route must be allowed via
Route Restriction Indexes (RRI) 0 & 1.
Note:
When using ASYDL or ASYDN to program an FCCS feature, the basic programming of ASYD is required in addition
to ASYDL or ASYDN.

D-9 Direct Outward Dialing (DOD)
D-9 Direct Outward Dialing (DOD)
General Description
This feature permits any user to gain access to the public network without the assistance of the Attendant, by dialing
an access code and receiving a second dial tone. The user may then proceed to dial the desired public network
number.
Operating Procedure
To place an outside call:
1. Go off-hook; receive dial tone,
2. Dial the trunk access code (usually “9”),
3. Receive second dial tone from Central Office,
4. Dial the desired telephone number,
5. If the call is denied for any reason, reorder tone is heard.
Service Conditions
1. Outgoing connection restriction can be assigned on an individual station basis. Refer to CLASS OF
SERVICE - INDIVIDUAL [C-15].
2. TOLL RESTRICTION - 3/6-DIGIT [T-7] may be applied to DIRECT OUTWARD DIALING.
3. Various types of trunks (FX, WATS, tie, CO, etc.) can be directly accessed using this feature.
4. The trunk group access code is limited to a maximum of three digits (only when the SPEED CALLING
[S-3, 3D, 21, 23] service is required).
5. Use of the DOD feature can be denied on a per-trunk group basis when the following restrictions are active
on the originating station line.
 Fully Restricted Stations: Direct Outward Dialing attempts are routed to reorder tone when the station
is fully restricted.
 Restriction from Outgoing Calls: A station assigned this feature is denied the ability to dial-access
preselected trunk groups.
 HOT LINE [H-1]: Exchange network call completion using this feature is not permitted. The
originating station can only be routed to the ATTENDANT CONSOLE [A-3] or another station when
going off-hook.
 MISCELLANEOUS TRUNK RESTRICTION [M-3]: Preselected station lines are denied access to
preselected miscellaneous trunk groups, the station is routed to reorder tone when the station attempts
to originate a call on the trunk group.
 TOLL RESTRICTION: Level of this feature restricts unauthorized station lines ability to complete
outgoing Central Office or Foreign Exchange calls to specified areas or office codes within an area.
 TOLL DENIAL: A station with Toll Denial is routed to reorder tone when a 0 or 1 is dialed as the first
digit after the trunk access code has been dialed.
6. The outgoing call using a trunk in the remote node via FCCS link is available. For more detailed
information, see the NEAX2400 IMX Fusion Network System Manual.
Interactions
The COT circuit card is used for all ringdown trunks. This circuit card is equipped to interface with Central Office
circuits and may be used for either loop start or ground start trunks.
