Item
Does the implementation indicate a stuff event in the ICP cell
preceding a stuff event using the mandatory LSI codes specified in
Table 2 on page 30?
Does the implementation perform stuffing by repeating the ICP cell
containing the LSI code indicating that “this cell is 1 out of 2 ICP
cells comprising the stuff event”?
Does the implementation also indicate an incoming stuff event in
the fourth, third, and second ICP preceding the stuff event using
the optional LSI codes?
At any given link, does the implementation ensure it does not
introduce a stuff event more than once every 5*M ICP, Filler and
ATM layer cells?
Does the implementation remove one of any two consecutive ICP
cells with LSI code indicating “this cell is 1 out of the 2 ICP cells
comprising the stuff event”?
Does the implementation ensure that the SICP cell is not counted
as a cell for the purposes of determining the IMA round-robin
sequence?
Does the implementation support CTC and ITC modes on receive?
Does the implementation inform the UM of a mismatch between
the FE and NE IMA transmit clock modes?
Does the implementation ensure that a restart is not caused if the
implementation detects a mismatch between the FE and NE
Transmit clock modes?
Does the implementation rely on at least one ICP cell with a correct
CRC-10 in order to process the incoming stuff cell indication code
(this is recommended)?
