适用范围：This International Standard specifies the 8-pole con-nector (plug and jack) and the assignments of poles/contacts for use in physical interfaces of Inte-grated Services Digital Network (ISDN) basic access arrangements. These physical interfaces may be lo-cated at reference points S and T between TEs and NTs and between NT1s and NT2s and shall conform to CCITT Recommendation l.430. This International Standard also specifies the re-quirements for ISDN basic access cords for use with TEs that conform with Recommendation l.430, where the specification of the TE calls for the use of such a cord. CCITT Recommendation l.430 requires plugs and jacks on equipment connecting cords and interface cables as shown in figure 2/l.430 of that Recommendation (also see annex A). For the purpose of this International Standard, when viewed from an NT1, an NT2 may be considered to be a TE. NOTE - This International Standard specifies connector dimensions but only those to ensure mateability of the plug and jack. Complete detailed specifications of the plugs and jacks and all other dimensions are specified in IEC 603-7 (see annex D)
