SLV Latency
Exceeded,
DLCI
nnnn
1, Port-1
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.
SLV Timeout,
DLCI

An excessive number of
SLV communication
responses from the remote

DLCI and link.
When a hardware bypass-
capable device has been
detected at the other end of
the PVC and this condition
occurs, only user data for
EDLCI0 will be transmitted
as long as the condition
exists.
Verify that the network LMI is up. If
it is, contact your network service
provider.
