The MIB for managing Signalling Points and its associated messages transported over Signalling System No. 7 (SS7) Network via Cisco IP Transfer Point. This MIB replaces the CISCO-ITP-SP-MIB and provide support multiple instances of a signalling point within same configuration.

The Cisco IP Transfer Point (ITP) is a hardware and software solution that transports SS7 traffic using IP. Each ITP node provides function similar to SS7 Signalling point.

The relevant ITU documents describing this technology is the ITU Q series, including ITU Q.700: Introduction to CCITT Signalling System No. 7 and ITU Q.701 Functional description of the message transfer part (MTP) of Signalling System No. 7.

This MIB models the GSP as follows:
