ABSTRACT: This document provides the Telcordia view of the Common Channel Signaling (CCS) Network Interface between a Local Exchange Carrier (LEC) and a Wireless Services Provider (WSP). This document includes CCS interconnection with WSPs where the LEC supports circuit-related applications using ISDN User Part (ISDNUP) signaling, pure Signaling System Number 7 (SS7) message transport using Message Transfer Part (MTP), and/or Signaling Connection Control Part (SCCP) signaling. It also supports Transaction Capabilities Application Part (TCAP) applications.

The new applications supported in this document include: Wireless Number Portability (WNP), emergency service E9-1-1 Phase 2, TCAP message transport for Wireless Intelligent Network (WIN) Phase 1 services, TCAP message transport for WNP database service, and TCAP message transport for wireless services impacted by number portability.
