- Scope
- This standard specifies the encoding of bearer capability (BC), high-level compatibility (HLC) and low-level compatibility (LLC) information elements used by terminals that support and implement on-demand ISDN telecommunications services specified in the 1.200 series of recommendations. This standard provides additional information on the use of the compatibility information unit for individual telecommunications services. See Chapter 3 for the list of telecommunications services included in this standard. This list will be updated as newly defined services and/or network functions and terminal equipment are improved. Since certain bearer capabilities support different user applications, additional information for these applications will specify: ——circuit-based 64kbit/s8kHz structured unrestricted bearer service (7.1); ——circuit-based 64kbit/s8kHz structured 3.1kHz audio bearer service (7.2) .
