unexpected CP type
CR, MJ,
MN, or
Status When associated with a FUNCTION UNITS slot,
this message means that a different but supported
circuit pack is inserted in a slot already
provisioned. When associated with a LOW SPEED
slot equipped with a DS1 circuit pack, this message
means that a different but supported DS1 circuit
pack type (for example, BBF3 circuit pack) is
inserted in a slot already provisioned. When
associated with a FUNCTION UNITS slot equipped
with a STS1E circuit pack, this message means
that the circuit pack type switch (located on the
circuit pack) is different from that already
provisioned for the slot. When associated with a
MAIN slot, if a 24G-U/24H-U OLIU or
29G-U/29H-U OLIU is inserted into a MAIN slot of
a Release 11 OC-3 shelf expecting a 22-Type
OLIU, the alarm level for the resulting
unexpected CP type
alarm is "status". If the
24G-U/24H-U OLIU or 29G-U/29H-U OLIU fails, a
OLIU CP failed
alarm is reported; but the
status condition is maintained until the circuit pack
is removed.
unsupported DCC connection
MJ DCC is enabled on an OC-1 connection between
the MAIN slots in two OC-3 shelves. The alarm is
cleared by disabling the DCC on the OC-1 interface
using the
set-fecom:
command. The DDM-2000
OC-3 system does not support a DCC link over an
OC-1 line terminating on the MAIN slots between
two OC-3 shelves.
X.25 communication failure
MJ Failure in the X.25 communication channel.
Likely causes: Failure of the X.25 communication
equipment or failure at the OS.
