This BITS structure can report the following failures: noDefect(0) - This bit position positively reports that no defect or failure exists. noCellDelineation(1) - The link was successfully initialized, but cell delineation was never acquired on the associated ATM data path. lossOfCellDelineation(2) - Loss of cell delineation on the associated ATM data path.

TEXTUAL-CONVENTION

Attributes with this syntax are status parameters that reflect the failure status for a given PTM interface (packet data path over an ADSL/ADSL2 or ADSL2+ link). This BITS structure can report the following failures: noDefect(0) - This bit position positively reports that no defect or failure exists. outOfSync(1) - Out of synchronization.

The ADSL2 management model specified includes an ADSL Mode attribute that identifies an instance of ADSL Mode-Specific PSD Configuration object in the ADSL Line Profile. The following classes of ADSL operating mode are defined. The notes (F) and (L) denote Full-Rate and Lite/splitterless respectively: +-------+--------------------------------------------------+ | Value | ADSL operation mode description | +-------+--------------------------------------------------+ 1 - The default/generic PSD configuration. Default configuration will be used when no other matching mode-specific configuration can be found. 2 - ADSL family. The attributes included in the Mode- Specific PSD Configuration are irrelevant for ITU-T G.992.1 and G.992.2 ADSL modes. Hence, it is possible to map those modes to this generic class. 3-7 - Unused.
