SUB ADDRESS - ADDRESSING
S-95 SUB ADDRESS - ADDRESSING
1. General Description
This ISDN feature permits an incoming call to be directed to a designated station by using called-party sub-
address information.
2. Operating Procedure
No manual operation is required.
Note: When ISDN Address information arrives from the ISDN line assigned for Sub Address-Addressing
and it does not contain the Sub Address information, the call is routed to an Attendant Console.
 When a D
term is designated as the destination of an incoming call, the calling party number is
automatically presented on the display of the Dterm.
3. Programming
STEP 1: Assign the Basic Data for ISDN (Refer to Chapter 3.)
STEP 2: ARTD - For the Route of the B-channels and D-channel of a 24PRT, which interfaces with the ISDN
line of Sub Addressing, assign DC (CDN 66)=“0”.

1. General Description
Communication using 56 kbps, 64 kbps (restricted) or 64 kbps (unrestricted) is possible with terminals
connected to AT&T’s ACCUNET network. The ACCUNET service needs to be provisioned by CO.
Note 1:The system does not determine communication compatibility; that is dependent on the terminal types.
Note 2:Data terminals that can be accommodated by the PBX are basically terminals with a transmission
speed of 64 kbps. Communication by terminals with other transmission speeds is not guaranteed.
2. Operating Procedure
No manual operation is required.

B-CHANNEL SERVICE CONTROL
B-27 B-CHANNEL SERVICE CONTROL
1. General Description
A PBX can send a trunk maintenance (SERVICE) message to the ISDN (AT&T-#4ESS, NT-DMS100/250)
when setting or cancelling a trunk make busy using the MBTK command. This function is not provided by NI-2
protocol.
Whether “In Service” mode or “Out of Service” mode of a PBX is determined by a trunk maintenance message
from the network. (Even if a PBX sent a trunk maintenance message setting the PBX to “Out of Service” mode,
the PBX would be set “In Service” when the PBX receives a trunk maintenance message for “In Service” from
the network.)

When a PBX has been set to “Out of Service” mode after receiving a trunk maintenance message from the
network, incoming calls from the network would not be allowed
.

Even if a PBX has been set to “Out of Service” mode after receiving a trunk maintenance message from the
network, incoming calls from the network would be allowed
.
2. Operating Procedure
Using MBTK,
Set make busy to a bothway call (MB=2): A PBX sends a trunk maintenance message.
Cancel the bothway make busy (MB=0): A PBX sends a trunk maintenance message.
3. Programming
None.
Note:SERV (Service) message = Trunk Maintenance message.
SERV (Service) ACK = Service acknowledgement.

CALL-BY-CALL POOL MANAGEMENT
C-106 CALL-BY-CALL POOL MANAGEMENT
1. General Description
A single PRI interface can be used in common by TRUNK PROVISIONING [T-42] and CALL-BY-CALL
SERVICE SELECTION [C-105]. If all the channels that are used by TRUNK PROVISIONING SERVICE
SELECTION are busy, it is possible to select the channels as used by CALL-BY-CALL SERVICE
SELECTION [C-105].
Note 1:The services that can be designated include the following:
ACCUNET, MEGACOM, MEGACOM800, and SDN.
Note 2:Channel selection is possible by the LCR function only.
2. Operating Procedure
No manual operation is required.
3. Programming
In addition to the Basic Office Data for ISDN, the following data should be assigned.
STEP 1: AFRS - Assign the different OPR (Outgoing Route Selection Pattern Number) on a service type
(such as ACCUNET, MEGACOM, etc.) basis.  Therefore, the OPR should be determined
according to the NPC (Number Pattern Code).
STEP 2: AOPR - Assign the common Route Number to all services (ACCUNET, MEGACOM, etc.).
STEP 3: ACBC - Select a desired service on an OPR basis.

CALL-BY-CALL SERVICE SELECTION
C-105 CALL-BY-CALL SERVICE SELECTION
1. General Description
Services can be selected on a call-by-call basis to all channels of a single PRI interface according to applications.
That is, unlike Trunk Provisioning Service in which services are assigned to specific channels, services may be
used on any available channel.
Note 1:The services that can be designated include the following:
ACCUNET, MEGACOM, MEGACOM800, and SDN.
Note 2:Channel selection is possible by the LCR function only.
Note 3:To identify a terminal to which a call has terminated, data must be registered using the “ACDD”
command so that a call-terminating terminal can be identified by a terminating number.
Note 4:During call termination, there is no indication of which service is being used.
2. Operating Procedure
No manual operation is required.
3. Programming
In addition to the Basic Office Data for ISDN, the following data should be assigned.
STEP 1: AFRS - Assign the different OPR (Outgoing Route Selection Pattern Number) on a service type
(such as ACCUNET, MEGACOM, etc.) basis. Therefore, the OPR should be determined
according to the NPC (Number Pattern Code).
STEP 2: AOPR - Assign the common Route Number to all services (ACCUNET, MEGACOM, etc.).
STEP 3: ACBC - Select desired service on an OPR basis.

CCIS TANDEM CALL-CALLING PARTY NUMBER (CPN) DELIVERY TO ISDN & Q-SIG NETWORKS
C-164 CCIS TANDEM CALL-CALLING PARTY NUMBER (CPN) DELIVERY TO ISDN & Q-SIG 
NETWORKS
1. General Description
This feature is provided for the call from tie line (CCIS line or Q-SIG) or a station, attendant console for
INDIVIDUAL ATTENDANT ACCESS [I-6] is sent to the public ISDN network (AT&T, NT, NI-2) or Q-SIG
network since Series 7400 software. With this feature, the calling party number can be changed as programmed
and sent to the ISDN network/Q-SIG network. Since the data can be set to designate the received number in
addition to the outgoing route to ISDN network, a variety of calling party number assignment is available.
2. Operating Procedure
No manual operation is required.
3. Service Conditions
1. This feature programmed by ACPNCL/ACPNCN command is effective when: 
 Calls are originated from CCIS/Q-SIG line to AT&T, NT, NI-2 or Q-SIG network.
 Calls are originated from the station to AT&T, NT, NI-2 or Q-SIG network.
 Calls are originated from the attendant console which is assigned the individual attendant identification
number to AT & T, NT, NI-2 or Q-SIG network.
2. This feature is not effective when calls are originated from AT&T, NT, NI-2 network to AT&T, NT, NI-2
network.
3. When the registered calling party number is received from CCIS line and sent to AT&T, NT, NI-2 network
by this feature, the access code and the office code, programmed as ACC for RT=0 (self-office) in ARNP,
are not deleted automatically as normal operation (take this into consideration when programming. See the
example data in Figure 6-2).
4. ACNP/ACND or AANDE command data are ineffective when the call corresponding to ACPNCL/
ACPNCN command data is originated to AT&T, NT, NI-2 or Q-SIG network. 
5. If number of digits of registered number (RCPN in ACPNCL/ACPNCN data) is less than that of calling
party number sent from CCIS/Q-SIG line, this feature is effective when the first part of the received calling
party number is identical with the registered number.
6. When assigning more than eight digits’ (includes the office code of the self office programmed in ARNP,
RT=0) number to be received from CCIS line, the number (RCPN in ACPNCL/ACPNCN data) must be
assigned as Physical Station Number since Physical Station Number is sent as the calling party number.
7. After the system is upgraded from non-fusion system to fusion system, Physical Station Number and
Telephone Number written in LDM that are programmed in ACPNCL command should be deleted and
assign the new Telephone Number using ACPNCN command unless those numbers are identical with
Telephone Numbers to be written in NDM. If the numbers are not deleted, the system gets the wrong number
data or does not get any number data since the fusion system reads out the NDM data.
8. The fusion system reads out the ACPNCN data. However, if there is no data in ACPNCN, the system reads
the ACPNCL data. The non-fusion system reads out the ACPNCL data only.
9. This feature is not available for the call originated using OAI/ACD feature.
