6.6.10C7SLC – CCS SS7 Signaling Link Change
Synopsis
This command is used to change the attributes of an SS7 signaling link.
Syntax
C7SLC:C7LINK=,{[EQU=,][SNLINK=,][TS=,][M56K=,][PCR=,]};
Prerequisites
•The specified link has already been initiated.
•The specified PCM time slot is not already assigned elsewhere in the system.
•The PCM on which the timeslot exists has been initiated.
•If specified, the board on which the EQU exists has been initiated.
•If specified, the PCM on which the timeslot exists has been initiated.
•The timeslot is a valid timeslot number for the PCM type (up to 31 for a E1 PCM and 24 for a T1 PCM).
•The signaling processor specified by the EQU parameter must be equipped with a valid board type and not already assigned to a link.
•All links within the link set must be blocked.
•If the EQU, PCR or M56K parameters are specified the link must be blocked and C7 links EQU board must be blocked. To change the other parameters on the C7 link, the link must be inhibited.
•If M56K is set to either 1 or 2, all links on the same board for which M56K is set to 1 or 2 must also use the same M56K value (that is, only one mode of 56kbits/s operation is supported on any board at one time. However, it is possible for some links to operate at 64kbits/s, while others operate at 56kbits/s).
•The signaling processor specified by the EQU parameter must be equipped with a valid board type and not already assigned to a link.
•All links within the link set must be blocked.
Note: After blocking, an SS7 link cannot be unblocked until all the boards processing the SS7 signaling are blocked and then unblocked.
•If the EQU, PCR or M56K parameters are specified, the link must be blocked and the C7 link’s EQU board must be blocked. To change the other parameters on the C7 link, the link must be inhibited.
•If M56K is set to 3 or 4, the TS cannot be specified and if M56K is not set to 3 or 4, the EQU must be specified.
•Only EQU signaling processors 1 and 2 can be used if M56K is 3 or 4.
•If an SNLINK is present, the EQU, TS, M56K and PCR cannot be present.
•If an SNLINK is specified, it’s SNTYPE must be M2PA.
•If an SNLINK is specified, it must be initiated, blocked and cannot be associated with any other SS7 link.
•The command cannot change between SNLINK and EQU type C7LINKs.
•SS7 links can use signaling processors 1 to 4 on a SPCI4 or SPCI2S board or 1 to 64 on a SS7HDP board.
