Primary Clock Failed
A failure of the configured
primary clock source for the
unit was detected and the
secondary clock is
providing the timing for the
unit.
This condition clears when
the configured primary
clock is restored.
Check that the network cable is
securely attached at both ends.
Contact your network provider.
Primary & Secondary
Clocks Failed
A failure of both clock
sources configured for the
unit was detected.
This condition only applies
to T1 network and DSX-1
interfaces. It clears when
the configured primary
clock is restored.
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.
