6.6.1 C7LSI – CCS SS7 Link Set Initiate

Synopsis

This command is used to initiate the SS7 link set (LS) between the point code of the unit, the Originating

Point Code (OPC), and an adjacent point code, the Destination Point Code (DPC). The user should specify the

maximum number of links in the link set (LSSIZE), the SS7 Signaling mode (SS7MD), which identifies the

point code size and mode of operation, and the Network Context (NC) the link set exists within.

See Section 7.2, “Signaling Configuration” on page 137 for a more detailed description of the SS7 Signaling

configuration.

This command is used to initiate the SS7 link set. Note that the DPC (Destination Point Code) is the adjacent

Point Code for the link set.

Syntax

C7LSI:LS=,OPC=,DPC=,LSSIZE=,NI=,SS7MD=,NC=,;

Prerequisites

• The SS7 link set has not already been initiated.

• The SS7MD associated with a NC cannot be different to an SS7MD associated with the same NC

anywhere else in the system.

• The NC/DPC combination must be different for all link sets.

• If SS7MD indicates 14-bit Point Code, OPC and DPC must be less than or equal to 16383.

• If SS7MD indicates 16-bit Point Code, OPC and DPC must be less than or equal to 65535.

• Only one OPC can exist within a network context.
