ABSTRACT: Integrated Customer Advanced Network Calling Number Identification Services (ICAN CNIs) extends the Primary Rate Access requirements in TR-NWT-001187, ISDN Calling Number Identification Services for Primary Rate Interfaces, by allowing Primary Rate Interfaces (PRIs) to pass Calling Party Numbers and Redirecting Numbers (RNs) from the ICAN Numbering Plan on calls that use ICAN routing. ICAN CNIS also allows PRIs to pass Connected Numbers (ConnNs) from the ICAN Numbering plan on calls that use ICAN routing. ICAN CNIS also extends the Basic Rate Access requirements in TR-TSY-000860, ISDN Calling Number Identification Services, by allowing Basic Rate Interfaces (BRIs) in a Basic Business Group (BBG) to pass Calling Party Numbers, Redirecting Numbers, and Connected Numbers in the ICAN Numbering Plan on calls that enter the BBG over ICAN facilities.

The existing PRI and BRI requirements for passing Calling Party Subaddresses and Redirecting Subaddresses are also extended to ICAN calls, and new PRI and BRI requirements for passing Connected Subaddresses on ICAN calls are added. Procedures for mapping these numbers and subaddresses from ICAN PRIs and ICAN BRIs to ICAN SS7-Supported Virtual Private Facilities (VPFs) (and vice versa) are also provided in this document.

This document presents the view of Telcordia on generic requirements for Integrated Customer Advanced Networking Calling Number Identification Services (ICAN CNIs).

Revision 1 replaces the Redirection Information Transfer (RIT) subscription parameter with the Service Information Transport - Call Associated Signaling (SIT-CAS) subscription parameter and deletes the RID subscription parameter. It also contains two modifications to the ICAN CNIS generic requirements that relate to ICAN Basic Business Groups (BBGs) and ICAN Electronic Tandem Switching (ETS) Services.

This GR also includes one or more Issue List Reports (ILRs) that details open or closed technical issues in the main document. The ILR(s) are automatically sent free of charge to the GR document purchaser.
