DDM-2000 OC-3 MULTIPLEXER
inc IMA Link RFI Status This status message indicates that the far-end IMA
terminating equipment (e.g. IMA LAN circuit pack)
has detected one or more failure conditions (e.g.
LOCD, Link Misconnect, DS1 AIS, DS1 LOF) on
the corresponding incoming IMA links and is
sending a remote failure indication (RFI) on its
transmitted signal. This message may have a
source address corresponding to one or more DS1
ports assigned to the IMA LAN circuit pack (e.g.
a-1-1.
inc MAC Err (from sonet) Status This status message indicates that the IMA LAN
circuit pack has discarded one or more MAC layer
protocol packets incoming from the SONET side.
This message has a source address of an IMA
LAN port (e.g. a-1).
Likely causes: If the 10/100 BaseX LAN is
operating in half-duplex mode this message may
result from congestion on the local area network. If
the LAN is operating in the half-duplex mode, this
message may result from a far-end IMA LAN circuit
pack failure.
inc AAL5 Err (from sonet) Status This status message indicates that the IMA LAN
circuit pack has dropped one or more AAL5
protocol packets incoming from the SONET side.
This message has the source address of an IMA
LAN port (e.g.a-1) and should always be
accompanied by an incoming LAN fail
(sonet) alarm.
Likely causes: The most likely cause is a local or
far-end IMA LAN circuit pack failure.
inc IMA Grp Abort NE Status This status message indicates that the near-end
IMA LAN circuit pack was unable to negotiate a
mutually acceptable IMA configuration with the
far-end IMA termination. The system was unable to
transition the IMA group into the operational state.
This message has the source address of an IMA
LAN port (e.g. a-1).
Likely causes: The near-end or far-end IMA
termination may need a provisioning change to
achieve mutually acceptable configuration
parameters.
