ACSC : Assignment of CSC Data

ACSC: Assignment of CSC Data

1.General

This command assigns the Common Channel Handler (CCH)/D-Channel Handler (DCH) location of the Common Channel Signaling Controller Group (CSCG).

2.Precautions

1.The CSCG represents the Point Code (PC) and the Circuit Identification Code (CICs) that correspond to the B-channels (voice channels) of the CCIS interface as assigned by the ACIC2 command. On the other hand, the CSCG represents the PC of the ISDN interface as assigned by the ACIC1 command.

2.The CSCG parameter accepts a range from 2 to 255 except 128 and 129.

3.The even number CSCG and its consecutive odd number CSCG are a CSCG pair. (Ex. CSCG2 and CSCG3 are the CSCG pair.)

4.In the case of CCIS, the CCH circuit entered in the CCH parameters within a CSCG pair share their work load. When CCH of GROUP0 has a heavy load, GROUP1’s CCH takes over the job. When all of the CCHs within the even number CCHs load becomes high, its consecutive odd number CSCG’s CCHs share their work load.

5.When it is an ISDN interface, the location of the DCH should be assigned in the CCH parameter of the even number CSCG within the CSCG pair. The first group of the PRT/DTI card is used for the location of the B-channel in the CCH parameter of the odd number CSCG.

6.The Common Channel Handler circuit handles the CICs means of B-channels. Table 4-26shows the relationship between GROUP and CICs.

7.The D-channel (signal channel) location should be entered in the CCH parameter as illustrated in Figure 4-29through Figure 4-31, CCT, PRT, CCH/DCH respectively.

When it is a CCT card, the Signal2 group is the location that should be entered in the CCH parameter of even and odd number CSCG.
