Definition
Far end ICP cell offset has changed in an IMA link.
Each IMA group assigns a unique Transmit offset to each link in the
group. this alarm means that a link was operating correctly, but
then received a Transmit offset already assigned to a previous link.
TX Misconnected alarm is also generated.
Status and Change Control Indication – the content of the ICP cells
has changed.
Far end rejects the M value used by the near end.
Far end group symmetry has changed in an IMA link.
Near end IMA networking Tx or Rx link state machine detects the
link is not connected to the correct FE Tx or Rx links.
Generated when Bad M, Bad Symmetry, BAD Offset, or Duplicated
ID alarms are generated.
Remote Failure Indication: Far end IMA Rx networking link state
machines detected LOS, OOF, AIS. LCD, LIF or LODS.
Near end has lost all its links in an IMA group. These links would
either have AFA, LOS, AIS, OOF, LCD or missing ICP cells.
Invalidates all the far end identity. If one or more links comes back,
re-identify and re-negotiate parameters with the far end group.
Different group IMA ID received on different links in an IMA group.
Different frame length received on different links in an IMA group.
Different group symmetry received on different links in an IMA
group.
Interface clock has been designated as the system clock, and the
interface clock has failed.
Interface clock has been designated as the system clock, and the
interface clock has failed.
Current alarms have been cleared by user
Alarm history table has overflowed. Alarms will continue to be
recorded but will displace oldest alarms.
Automatic Frequency Adjustment – Link removed from physical line
group due to error rate in CRC check of T1/E1 exceeding user
specified rate for a given period of time.
Local Management Interface has taken the link down
The link has exceeded the user selectable value for acceptable link
delay.
Link is removed from the group.
Same group IMA ID received on links belonging to different IMA
group in the same card.
links configured by the user.
There are less configured links than IMA links required to make an
IMA group active.
Problem with the SAR chip on the CTX.
In band loopback is turned on.
