ACSCL : Assignment of CSC Data for LDM

ACSCL: Assignment of CSC Data for LDM

1.General

This command assigns the Common Channel Handler (CCH) location of the Common Channel Signaling Controller Group (CSCG). This data is written in Local Data Memory (LDM).

2.Precautions

1.The CSCG represents the Point Code (PC) and the Circuit Identification Code (CIC) which correspond to the B-channels (voice channels) of the CCIS interface as assigned by the ACIC2 command.

2.The CSCG parameter accepts with 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.The CCH circuit handles the CICs (B-channels). Table 4-27shows the relationship between GROUP and CICs.

	Table 4-27 Relationships Between GROUP and CICs (ACSCL)
GROUP		CIC
GROUP 0		CIC8, CIC16, CIC24 ·························· CIC992
GROUP 1		CIC1, CIC9, CIC17, CIC25 ··············· CIC993
GROUP 2		CIC2, CIC10, CIC18, CIC26 ············· CIC994
GROUP 3		CIC3, CIC11, CIC19, CIC27 ············· CIC995
GROUP 4		CIC4, CIC12, CIC20, CIC28 ············· CIC996
GROUP 5		CIC5, CIC13, CIC21, CIC29 ············· CIC997
GROUP 6		CIC6, CIC14, CIC22, CIC30 ············· CIC998
GROUP 7		CIC7, CIC15, CIC23, CIC31 ············· CIC999

6.The D-channel (signal channel) location should be entered in the CCH parameter as illustrated in Figure 4-32and Figure 4-33, CCT, CCH respectively.

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

The CCH card equipped two circuits of Common Channel Handler on a card, thus the “CCH0” and “CCH1” are the locations to enter in the CCH parameter.
