LOS at Net, Pt n An LOS (Loss Of Signal)
condition has been detected
on the network interface. No
signal is being received on
Port
n, possibly due to a local
network problem.
1. Verify that the network cable
is securely attached at both
ends.
2. Verify proper NTU and LTU
configuration.
3. Contact network provider.
Mismatch Rate,
Pt
n
The LTU, in fixed rate, is
attempting to communicate
at a faster rate than the NTU
can handle. 1. Verify endpoint is not a 1
Mbps model.
2. Upgrade remote unit to a 2
Mbps or reconfigure the LTU
for fixed rate at a lower rate.
Net Margin Threshold,
Pt
n
The signal-to-noise margin
has exceeded the configured
threshold for Port
n.
1. Check the Network
Performance Statistics
screen for possible line
impairments.
2. Set the unit to run at a lower
DSL line rate.
3. Contact network provider.
NTU TS16 Not
Supported The LTU is configured for
TS16 signaling and the NTU
is not configured to support
TS16 signaling. 1. Verify endpoint is a G.703
product. EIA-530-A products
do not support signaling.
2. Replace endpoint or
reconfigure TS16 to data.
OOF at Net, Pt n Three consecutive frame
synchronization bits were in
error. 1. Verify proper NTU and LTU
configuration.
2. Check the Network
Performance Statistics
screen for possible line
impairments.
3. Set the unit to run at a lower
DSL line rate.
4. Contact network provider.
Primary Clock Failed
(G.703 Pt 1) A failure has occurred in the
primary clock source
configured for the G.703 port. 1. Verify that the network cable
is securely attached at both
ends.
2. Contact network provider.
RAI (Remote Alarm
Indication) at G.703
interface, Pt
n
A Remote Alarm Indication
signal is being received by
the G.703 interface. 1. Check the status of the
upstream device.
2. Verify proper NTU and LTU
configuration.
System Operational There are no problems
detected. No action is needed.
