This guide describes how to deploy, manage and maintain the OCSS7 SGC component of Metaswitch’s SS7 Stack.

The SGC works in concert with CGIN to deliver SS7/SIGTRAN capability to Rhino. For information on configuring CGIN to use OCSS7, and other technical details and considerations about SGC to CGIN communication, please see Using the OCSS7 TCAP stack in the CGIN manual.
