Loop Testing Messages at the OS/TSC Interface

Document Number GR-202
Issue Number 02
Issue Date Nov 1995
Replaces TA-TSY-000202 Issue02

    ABSTRACT: This document presents the view of Telcordia on generic requirements for messages to accomplish the testing of customer loops (Plain
    Old Telephone Service or POTS) over the Operations System/Test System Controller-Remote Test Unit (OS/TSC-RTU) interface. The
    interface carrying this loop testing information shall be built on a non-Open Systems Interconnection (OSI) (X.25) protocol stack and
    shall use the Transaction Language 1 (TL1) message syntax and semantics. The functional requirements for loop testing are described in
    GR-844, TSC/RTU Generic Requirements for Metallic Loop Testing. These two documents should be considered companion
    documents and should be referenced together to achieve a more concise foundation for implementing a Loop Testing system.

    GR-202 replaced TA-TSY-000202.
