This read-only INTEGER (1..2) indicates the 'alpha' value specifying the number of consecutive invalid ICP cells that must be detected before the IMA state machine moves a link to the HUNT state, though only the default value is actually supported. An administrator uses this as a state-machine sensitivity constant governing how quickly the group declares link synchronization lost due to invalid control cells. For example, since only the default alpha is supported, an operator cannot tune this sensitivity and should expect the platform's built-in default behavior for detecting invalid ICP cell sequences.
