Maintenance Description
Issue 8.0 July 2002
9-29
sync mode auto switch An automatic switch from the provisioned
operating mode to holdover mode has
occurred. Likely cause: All incoming
synchronization references have failed.
sync mode forced switch A forced switch from the provisioned
operating mode to holdover mode has
occurred.
sync reference auto switch The FT-2000 terminal has automatically
switched its synchronization reference.
Likely causes: When provisioned for
phase-locked synchronization mode, failure
of the external DS1 synchronization
reference. When provisioned for loop timed
mode, failure of the incoming OC-48 line,
failure of the RCVR circuit pack, or failure of
the external DS1 synchronization reference.
sync reference forced switch The FT-2000 terminal has switched its
synchronization reference with a priority of
"forced switch."
sync reference lockout A synchronization reference signal is locked
out and FT-2000 terminal will go into
holdover mode if it fails.
sync reference manual switch The FT-2000 terminal has switched its
synchronization reference with a priority of
"manual switch."
SYSCTL failure Failure of SYSCTL circuit pack.
SYSMEM failure Failure of SYSMEM circuit pack.
SYSMEM removed SYSMEM circuit pack is missing from slot.
SYSMEM/SYSCTL code mismatch A software mismatch has been detected
between the software stored in the
SYSMEM circuit pack and the software
version running in the FT-2000 network
element. Likely cause: A software upgrade
procedure is in progress.
SYSMEM unrecognizable code The software stored in the SYSMEM circuit
pack has become corrupted and is no longer
usable.
Likely causes: Corrupted software download
to SYSMEM circuit pack or spontaneous
corruption of the software in the SYSMEM
circuit pack.
test alarm in progress An office alarm test is in progress.
