Abstract
Overview
ISO/IEC 17311:2000 - Information technology - Telecommunications and information exchange between systems - Private Integrated Services Network - Mapping functions for the employment of 64 kbit/s circuit mode connections with 8 kbit/s sub‑multiplexing - defines the mapping functions required to interconnect Private Integrated Services Network Exchanges (PINXs). The standard specifies a of a single 64 kbit/s circuit mode connection (D64U) to one 16 kbit/s signalling channel and six 8 kbit/s user channels at the Q reference point. It covers physical adaptation, channel mapping and bearer capabilities for inter‑PINX connections (IPC) using ITU‑T G.703 style interfaces.
