Issue 10 of GR-246-CORE, Telcordia Technologies Specification of
Signalling System Number 7, replaces Issue 9.

GR-246-CORE defines the procedures and protocol by which network elements in
the Public Switched Telephone Network (PSTN) exchange information over a digital
signaling network. This enables wireless and wireline call setup, routing, and
control.

This document:

• Contains the fundamental specification of SS7, which is then used as a
  basis for other generic requirements documents for Common Channel Signaling
  (CCS) network elements


• Is based on the latest ANSI T1 Standards agreements and is critical for
  vendor implementations and carrier deployment


• Ensures that SS7 messages are transported without alteration and ensures
  interoperability, potentially saving millions


• Lists all the signaling point codes assigned to network carriers

• Message Transfer Part (MTP)


• Signaling Connection Control Part (SCCP)


• ISDN User Part (ISUP)


• Transaction Capabilities Application Part (TCAP)


• Operation, Maintenance, and Administration Part (OMAP)

• Addition of a new section specifying interworking between the Session
  Initiation Protocol (SIP) and the ISUP protocol


• Updated signaling point code assignment guidelines to assign point codes for
  CCS network use by carrier


• Updated signaling point code assignment list.
