Does the implementation abort the start-up procedure using the
appropriate code defined in the “Group Status and Control” field of
the ICP cell (as specified in Table 2 on page 31) if the symmetry
mode proposed by the FE and the configured symmetry mode of
the NE do not match?
In order to allow a fast recovery when (O-5) or (O-6) is used at the
NE and when the FE IMA unit can only be configured to the
"Symmetrical Configuration and Operation" mode, does the
implementation adjust to “Symmetrical Configuration and
Operation”.
Does the implementation support only the valid combinations of
group symmetry modes at each end of the IMA virtual link as
specified in Table 4 on page 36?
Does the implementation allow configuration of the group mode?
Does the implementation support all ATM traffic/QoS classes
supported by the ATM layer?
Does the implementation indicate to the FE in which transmit clock
mode it is running in the “Transmit Clock Mode” field in the ICP
cell?
Does the implementation support the CTC mode in the transmit
direction?
Does the implementation only indicate to the FE that it is in the CTC
mode when all the “transmit” clocks of the links in the group are
derived from the same source?
Does the implementation support the ITC mode in the transmit
direction?
Does the implementation indicate that it is in the ITC mode even if
all the transmit clocks of the links in the group are derived from the
same source?
Does the implementation use the cell stuffing procedure to prevent
link transmit buffer under-run or over-run?
