1.3.9. [CCS] Section

The Common Channel Signaling (CCS) component resides on the control processor. The CCS component applies to technologies such as ISDN that use common channel signaling.

The [CCS] section of the CONFIG file is a subcomponent of the [TSC] section and contains common channel signaling parameters. Under the [CCS] section, there is typically one [CCS.x] section for each line on the board. The [CCS] section of the CONFIG file defines board based parameters and the [CCS.x] section defines the line based parameters. Each [CCS.x] section defines the CCS parameters that apply to line x, for example, parameters in the [CCS.2] section apply to line 2.

CCS parameters are modified by editing the respective lines in the [CCS] or [CCS.x] sections of the CONFIG file. For example, to change the CCS_TMR_308 parameter (parameter number=0x0e) from a value of 4000 milliseconds to 3000 milliseconds for the fourth T-1 span, you would change the value in the [CSS.4] section from 4000 to 3000.

Following is an excerpt from the [CCS.4] section of the CONFIG file that illustrates that part of the file before and after editing:

Before editing:

Setparm=0x0d,4000     !Q.931 timer 305. Default=4000 msec.
Setparm=0x0e,4000     !Q.931 timer 308. Default=4000 msec.
Setparm=0x0f,10000    !Q.931 timer 310. Default=10000 msec. 

After editing:

Setparm=0x0d,4000     !Q.931 timer 305. Default=4000 msec.
Setparm=0x0e,3000     !Q.931 timer 308. Default=4000 msec.
Setparm=0x0f,10000    !Q.931 timer 310. Default=10000 msec. 

For information about each CCS parameter, see Section 4.14, [CCS] Parameters.
