APPENDIXI-Bibliography Abstract
Specifies electrical, physical, procedural and protocol requirements for the V5.1 interface between an Access Network (AN) and the Local Exchange (LE) for the support of the certain access types - e.g. analogue telephone access, ISDN basic access with a line transmission system conforming to ITU-T G.960, ISDN basic access with a user network interface according to ITU-T I.430, and other analogue or digital accesses for semi-permanent connections without associated outband signalling information.
