Table 36 Possible IMA Group Failure Status Conditions
Failure Description
Near End Asymmetric Near end rejected asymmetrical configuration or operation
chosen by the far end.
Far End Invalid M Far end rejected the M value chosen by the user on the
near end.
Other Failures The near end group detected multiple IMA ID, multiple M,
or multiple symmetry, or the group has duplicated IMA ID,
or the far end reported configuration abort without any
reason.
Near End Insufficient This is a normal transitional state when the near end group
Links is coming up. If it persists, it indicates that the group
indeed does not have enough links to come up and pass
data.
Far End Insufficient This is a normal transitional state when the far end group
Links is coming up. If it persists, it indicates that the group
indeed does not have enough links to come up and pass
data.
Near End Blocked The near end group cannot pass data due to LODS.
Far End Blocked The far end group has enough links, but cannot pass data
for some other reason.
Near End Startup This is a normal transitional state when the near end group
is coming up.
Far End Startup This is a normal transitional state when the far end group
is coming up.
No Failure The group has no failure.
FE Tx Clocking—Far-end transmit clocking mode: common or independent.
Tx Timing Ref. Link—The near end transmitting timing reference port for cell
clock recovery: 1 to N.
Rx Timing Ref. Link—The near end received timing reference port for cell clock
recovery: 1 to N.
Rx IMA ID—The IMA receive group ID: 0-255. This number reflects the remote
IMA ID.
NE State Last Changed—The date and time at which the near-end state last
changed.
Rx Framer Length—Receive M value: 32, 64, 128, or 256. The frame length of
the first link that can communicate with the far end is chosen as the frame length
of the far end group.
Least Delay Link—The port number of the fastest link in the group.
Oper. LInk Delay—Operational link delay; the actual value of the link differential
delay: 0-70 msec for T1, 0-50 msec for E1.
Tx Avable. Cell Rate (cps)—The available cell rate for active Tx links in this
group: 0-28,728 cps for DS1, M=128; 0-35,920 cps for E1, M=128. The available
cell rate indicates how much bandwidth can be carried across the group. It varies,
depending on how many links in the group are actually working.
