Integrated Services Digital Network (ISDN) - Data-Link Layer Signalling Specification for Application at the User-Network Interface

This National Standard of Canada is equivalent to American National Standards Institute (ANSI) standard ANSI T1.602-1989. It specifies the Link Access Procedure on the D-channel, LAPD. The purpose of LAPD is to convey information between layer-3 entities across the ISDn user-network interface using the D-channel. LAPD is a protocol operating at the data link layer of the OSI architecture. This standard specifies the use of LAPD on a duplex, bit-transparent D-channel on an ISDN interface. The frame structure, elements of procedure, format of fields, and procedures for the proper operation of LAPD are specified.
