ABSTRACT: Issue 15 of GR-82, Signaling Transfer Point (STP) Generic Requirements, replaces Issue 14.
This document provides the view of proposed generic requirements and objectives for a typical Common Channel Signaling (CCS) Network
Provider utilizing Signaling Transfer Points (STPs) in their CCS network. STPs are packet switches in the CCS network that transfer
messages from one signaling link to another at Level 3.
A client company typically uses STPs to connect various Signaling Points (SPs) within its own network and to connect to SPs in other
networks. STPs using the Signaling System Number 7 (SS7) protocol, as defined in GR-246, provide efficient transport of messages for
trunk signaling and database services in a CCS network. A primary role of the STP in a CCS network is to provide overall network
management functions to help ensure the prevention, detection, recovery, and supervision of CCS network failures.
These requirements describe the features and functionalities of STPs by defining their interaction with the SS7 protocol, signaling
networks, and operations systems. This document is intended to help provide the basis for the CCS network architecture, procedures to
implement SS7 protocols, and descriptions of provisioning, administration, and operational interfaces that can facilitate operation of
the client companies CCS networks. Also included are capacity requirements and performance objectives to meet the overall reliability
standards in a client company environment.
This document will enable equipment suppliers to implement and upgrade STPs that meet functional and operations requirements of
typical local exchange carriers in North America, and that reliably interoperate with other suppliers' SS7 network elements and with
the carriers' network operations support systems.
Issue 15 contains modified measurement names, functional descriptions and measurement definitions of several STP system total
