SHDSL Line MIB

RFC 3276, Definitions of Managed Objects for High Bit-Rate DSL - 2nd generation (HDSL2) and Single-Pair High-Speed Digital Subscriber Line (SHDSL) Lines, defines a portion of the Management Information Base (MIB) for managing High Bit-Rate DSL - 2nd generation (HDSL2) and Single-PairHigh-Speed Digital Subscriber Line (SHDSL) interfaces. These interfaces correspond to entries in the ifTable with an ifType of hdsl2 (168) or shdsl (169), respectively.

Objects in the MIB represent the SHDSL line from the perspective of:

■a central site terminal unit (STU-C)

■a remote site terminal unit (STU-R)

■a regenerator unit (SRU)

The objects defined in this MIB reside in the mib(1) subtree, under the Transmission Group defined in MIB-II and have the object identifier is hdsl2ShdslMIB { transmission 48 }. Objects in the SHDSL MIB are organised into the following groups:

■The Span Configuration Group contains objects that describe the configuration of the SHDSL span.

■The Span Status Group contains objects that describe the status of the SHDSL span.

■The Unit Inventory Group contains objects that describe the units in SHDSL lines. The unit inventory information is retrieved via the EOC.

■The Segment Endpoint Configuration Group contains objects that describe the configuration of the SHDSL segment endpoints.

■The Segment Endpoint Current Status/Performance Group contains objects that describe the current status and performance of segment endpoints.

■The Segment Endpoint 15-Minute Interval Status/Performance Group contains objects that describe the historic status and performance information of segment endpoints in 15-minute intervals.
