适用范围：This International Standard specifies the 8-pole connector (plug and jack) and the assignments of poles/contacts for use in physical interfaces of Integrated Services Digital Network (ISDN) basic access arrangements. These physical interfaces, where they exist, will be located at reference points S and T between TEs and NTs and between NT1s and NT2s and shall conform to CCITT Recommendation 1.430.CCITT Recommendation 1.430 requires plugs and jacks on equipment connecting cords and interface cables as shown in figure 2/I.430 of that Recommendation (see also 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 intermatabihty, complete detailed specifi-cations of the plugs and jacks and all other dimensions will be the sub-ject of a future IEC standard.
