Information technology. Telecommunications and information exchange between systems. Interface connector and contact assignments for ISDN primary rate access connector located at reference points S and T shop-only Wiring systems and circuit requirements1 Scope This International Standard specifies the 8 contact connector (plug and jack) and the assignments of its contact numbers for use in the physical interfaces of Integrated Services Digital Network (ISDN) primary rate access services conforming to ITU T Recommendation I. 431. In this International Standard, as in ITU T Recommendation I. 431, the term "NT" is used to indicate the network terminating layer 1 aspects of NT1s and NT2s, and the term
