C-IF 3.02-02-TS
PHS-FWA System:
Interface Specification between FWA Access Controller and Service Node-ITU-T G.964:V5.1 Interface1. General
This specification defines a V-interface (V5.1) for the connection of a FWA Access Controler(WAC)
to a Service Node (SN) for the support of the following access types:–analogue telephone access;–ISDN basic access;–other analogue or digital accesses for semi-permanent connections without associatedoutband signalling information,with flexible information channel allocation but without concentration capability within the WAC.
Interface V5.1 is upgradable to V5.2 through re-provisioning and by implementation of the additionalfunctionality.
2. Interface Specification
This specification is conformed to ITU-T Recommendation G.964.
3. Comments for Implementation
This Clause shows examples of PSTN sequence on V.5.1 interface (see Annex A).
