rate, is attempting to operate
at a rate the NTU is not
capable of.
Net Margin Threshold, The signal-to-noise margin
Pt n has dropped below the
configured threshold.
NTU/LTU Mismatch, The NTU is not compatible
Pt n with the LTU.
NTU TS16 Not The LTU is configured for
Supported TS16 signaling and the NTU
is not configured to support
TS16 signaling.

7. Monitoring and Troubleshooting
What To Do
1. Verify that the network cable
is securely attached at both
ends.
2. Verify proper NTU and LTU
configuration.
3. Contact network provider to
troubleshoot the line.
Set the LTU to a compatible rate
or replace the NTU.
1. Check the Network
Performance Statistics
screen for possible line
impairments.
2. Set the unit to run at a lower
DSL line rate.
3. Reconfigure the margin
threshold (if appropriate).
4. Contact network provider to
troubleshoot the line.
Contact network provider.
1. Verify endpoint is a G.703
product. EIA-530-A products
do not support signaling.
2. Replace endpoint or
reconfigure TS16 to data.
1. Check the Transmit Clock on
the unit and attached
equipment.
2. Set the unit to run at a lower
DSL line rate.
3. Contact network provider.
Reconfigure the EIA-530
Payload Rate configuration
option to an acceptable rate.
See Network Interface Options
Menu
in Appendix A,
Configuration Options for
acceptable rates.
