The scope of this standard is to Develop an ISLAN interface at the medium access control (MAC) sublayer and the Physical (PHY) Layer compatible with IEEE 802.x and ISDN standards and architecturesDevelop an ISLAN interface that operates independently from the backbone networkFocus upon unshielded twisted-pair wiring as the primary distribution mediumEnable implementation of IS terminal equipment (ISTE) that accesses IEEE 802 LAN and ISDN services through a common interface The body of this standard Defines the service provided by the MAC sublayer to the IEEE 802 Logical Link Control (LLC) sublayer and management, and describes the services provided by the PHY Layer to the MAC sublayer and management in terms of service primitives and associated parametersDescribes the services provided by the Physical Layer (PHY MUX) to support a basic rate interface (BRI) ISDN in terms of service primitives and associated parametersDescribes the services provided by the PHY MUX to the isochronous channelsSpecifies the MAC functions that allow ISTEs access to one another and to LANs providing IEEE 802 services and/or ISDN servicesSpecifies the frame format for the MAC frameDefines the MAC protocolSpecifies the channel structure and frame format of the time division multiplexed (TDM) frameSpecifies the PHY Layer functions over unshielded telephone twisted-pair (UTTP) cableSpecifies the characteristics of the UTTP attachment of the station to the access unit (AU) including the specification of the medium interface connectorSpecifies the definition of MAC and PHY managed objects (Mos)Describes recommended ISDN signalling and management methods to coordinate the multiple channels operated between ISTEs and the AU The normative annexes provide The Protocol Implementation Conformance Statement (PICS) proformaThe Managed Object Conformance Statement (MOCS)The Guidelines for the Definition of Managed Objects (GDMO) specificationsSupplemental recommendations on the use of CCITT Q.93x signalling procedures The informative annexes provide Reference models of common configurations as guidelines for implementationA sequence and description language (SDL) description of the information flow across protocol layersDescription of an optional remote secure control (RSC) procedure to invoke secure communication device (SCD) operationsRecommendations for a common, consistent synthesis of ISDN and IEEE 802 that conforms with the addressing of ISTE devices and servicesDescription of a mechanism to support the transport of a broadband ISDN conformant cell bearer service
