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.
