Description: This table extends the adslLineTable in support of an ADSL Line object.

The objects pdnAdslLineTransAtucCap, pdnAdslLineTrans- AtucConfig, and pdnAdslLineTransAtucActual exist along with their PdnAdslTransmissionModeType TC because the AdslTransmissionModeType defined in the ADSL-LINE-EXT-MIB does not include the ADSL2/ADSL2plus bits defined in ITU G.997.1 (05/2003) ATU Transmission System Enabling (ATSE) section.

When using the objects defined in this MIB with a syntax of type PdnAdslTransmissionModeType, the interworking relationship between these objects and the objects defined in the ADSL-LINE- EXT-MIB defined with a syntax of type AdslTransmissionModeType must be considered and explained in an implementation-specific document such as an Operational Specification. Note that the PdnAdslTransmissionModeType is a super set of the AdslTransmis- sionModeType. One possible implementation could be as follows: 1. Both objects of syntax AdslTransmissionModeType defined in the ADSL-LINE-EXT-MIB and objects of syntax PdnAdsl- TransmissionModeType defined in this MIB are supported. By supporting both, a manager with the ADSL-LINE-EXT-MIB loaded could manage the device with the restriction of not being able to utilize ADSL2/ADSL2plus modes. 2. When the ADSL2/ADSL2plus capabilities are desired, a manager would have to use the objects defined in this MIB to configure the transmission modes, read capability, or read the actual transmission mode of the ATU-C. 3. The transmission mode that the ATU-C is currently configured for is based on the last object, adslLineTrans- AtucConfig or pdnAdslLineTransAtucConfig, that was written.
