Item
Does the implementation perform IMA frame synchronization on
each link, based on the IFSM defined in Figure 19 on page 69 and
Table 16 on page 69?
Does the implementation operate the IFSM for each link
independently of any link defects and link delay compensation?
Does the implementation support the default value 2 for Alpha(α)?
Does the implementation support the default value 2 for Beta(β)?
Does the implementation support the default value 1 for
Gamma(γ)?
Does the implementation support the value 1 for Alpha(α)?
Does the implementation support the value 1 for Beta(β)?
Does the implementation support the value 3 for Beta(β)?
Does the implementation support the value 4 for Beta(β)?
Does the implementation support the value 5 for Beta(β)?
Does the implementation support the value 2 for Gamma(γ)?
Does the implementation support the value 3 for Gamma(γ)?
Does the implementation support the value 4 for Gamma(γ)?
Does the implementation support the value 5 for Gamma(γ)?
Does the implementation assume that any occurrence of HEC/CRC
errored cell in the ICP cell position was an ICP cell?
Does the implementation ignore the cell content of a HEC/CRC
errored cell in the ICP cell position?
Does the implementation go into the Hunt state from any other
state when no longer getting cells from the physical layer?
Does the implementation maintain IMA frame synchronization for
cases 1, 2, 3, and 6 identified in Figure 20 on page 71?
Does the implementation maintain IMA frame synchronization for
case 4 identified in Figure 20 on page 71?
Does the implementation maintain IMA frame synchronization for
case 5 identified in Figure 20 on page 71?
Does the implementation maintain IMA frame synchronization for
case 7 identified in Figure 20 on page 71 when passing stuff
indication over more than one of the previous ICP cells and when
Beta(β) is greater than 2?
