This configuration parameter defines the line states to be forced by the near-end ATU on this line. It is coded as an integer value with following definition: L0_FullOn Force the line to transition from the L3 idle state to the L0 full-on state. This transition requires the (short) initialization procedures. After reaching the L0 state, the line may transition into or exit from the L2 low power state (if L2 state is enabled). If the L0 state is not reached (after a vendor discretionary number of retries and/or within a vendor discretionary timeout), then an Initialization Failure occurs. Whenever the line is in the L3 state, attemps shall be made to transition to the L0 state until it is forced into another state through this configuration parameter. L2_LowPower Force the line to transition from L0 full on to L2 low power state. This transition requires the entry into L2 mode. This is a out-of-service test value for triggering the L2 mode. L3_Idle Force the line to transition from the L0 full-on or L2 low power state to the L3 idle state. This transition requires the (orderly) shutdown procedure. After reaching the L3 state, the line shall remain in the L3 idle state until it is forced into another state through this configuration parameter. Forced line state transitions require the line to enter or exit from the L3 idle state. These transitions are not restricted by the Line state enabling parameter value. NOTE - Supported for ADSL2/ADSL2plus ONLY. This configuration parameter maps to the AdminStatus of the line, which is part of the GeneralInformationGroup object group specified in RFC 2233, and may not need to be duplicated in the ADSL MIB. See also RFC2662. The Administrative Status of the line is UP when the line is forced to the L0 state and is DOWN when the line is forced to the L3 state.
