Mismatch Rate The LTU, set to Fixed Rate
mode, is attempting to
operate at a DSL line
speed faster than the NTU
can handle.

communication link is
down. Communications
between the management
system and the LTU/NTU
is not possible.

securely attached at both ends.
2. Verify the link protocol for the
COM port is configured correctly.
3. Verify that no tests are active.
1. Reconfigure the unit to a higher
Net Margin Threshold.
2. Contact network provider.
Configure units to match.
1. Verify endpoint is a G.703
product. EIA-530-A products do
not support signaling.
2. Replace endpoint or reconfigure
TS16 to data.
Contact network provider.
1. Verify that the network cable is
securely attached at both ends.
2. Verify your clock configuration.
3. Contact network provider.
1. Verify that the units line framing
and line coding are compatible.
2. Contact network provider.
Verify that the DTE is providing the
monitored signals.
1. Verify that the units line framing
and line coding are compatible.
2. Contact network provider.
