Secondary Clock
Failed
A failure of the configured
secondary clock source for
the unit was detected and
the internal clock is
providing the timing for the
unit.
The clock source will not
automatically switch from
internal until the primary
clock source returns.
Self-Test Failure The unit did not pass its
basic verification tests when
it was powered on or reset.
Reset the unit.
Contact your service
representative.
SLV Latency
Exceeded, DLCI
nnnn
,
frame relay link
1, 2, 3
The measured latency of
SLV communication
responses from the remote
unit on this DLCI is
excessive, so the DLCI has
been declared unsuitable
for normal multiplexed PVC
operation (DLCI Type is set
to Multiplexed).
Wait until the DLCI is declared
operational again.
If the unit has ISDN backup
capability, this condition will
initiate backup.
SLV Timeout, DLCI
nnnn
,
frame relay
link
1, 2, 3
An excessive number of
SLV communication
responses from the remote
system have been missed
on the specified multiplexed
DLCI and link.
If the frame relay link is
Net1-FR1, the timeout is on
the network FrameRly1
timeslot assignment.
When a hardware bypass-
capable device has been
detected at the other end of
the PVC and this condition
occurs, only user data for
EDLCI 0 will be transmitted
as long as the condition
exists.
Verify that the network LMI is
up. If it is, contact your network
service provider.
If a DBM is present and Auto
Backup is enabled, backup is
initiated automatically.
