BASIC DATA ASSIGNMENT

2.3 FCCS Data Assignment Procedure

This section explains the basic data assignment to be required when CCIS services are activated in an FCCS Net- work. Feature and Specifications Manual shows the CCIS services allowed in an FCCS Network. See “FCCS Net- work System Manual” and “Office Data Specification Manual” for details.

Note: This data setting is necessary for the following services since they may be provided to FCCS system.

•CENTRALIZED MAINTENANCE-CCIS [C-167]

•NUMBER PORTABILITY-CCIS [N-46]

For details of this feature, see “Feature Programming Manual”.

When the above features are used, there are conditions of FCCS data assignment as described below.

1.When connecting the stand-alone PBX, non-FCCS system, with another FCCS Group (FUG) or NEAX2000IPS,

(a)The system must be the NCN.

(b)The system is programmed as the FCCS Network configured by one NCN only.

(c)Use the NDM of the system to program the network data.

2.When connecting the NEAX2400IPX system and the NEAX2000IPS system, CIC (Circuit Identification Code) =1 should always be assigned using ACIC2 command.

3.Common Channel Handler (CCH) location of the Common Channel Signaling Controller Group (CSCG) data (CCH location per CSCG) must be programmed against each PC of the connected IPX or IPS system using ACSCL command.

4.PCs (Point Codes) in the network through FUGs and IPS are programmed as unique (All PCs used in the net- work are different).

For the system to be connected with the next system via CCIS link or the large sized network, this assignment is basically recommended.

5.The CCH to be used is selected as follows.

1when the call is processed using the speech line (Bch), the outgoing/incoming route (Logical Route: LRT) decides CCH.

LRT → PC → CSCG → CCH

2when the call is processed without speech line (Bch) - inter-office service such as CALL BACK, MES- SAGE WAITING service, MCI, etc., the called party’s number or PC of the destination decides CCH.

(a)the called party’s number → LRT → PC → CSCG → CCH

(b)PC → CSCG → CCH

3when logging into IPS or IPX in the remote FUG from the Centralized-MAT, PC of the node to be logged in decides CCH.

(a)IPS

PC → CSCG → CCH

(b)IPX in Remote FUG

FUG + FPC → PC → CSCG → CCH

*FUG and FPC to be designated for logged-in node are converted automatically within the system.
