-4
) for 5 seconds.
RAI at Net A Remote Alarm Indication is being received by the network interface.
RAI at DTE A Remote Alarm Indication is being received by the G.703 DTE interface.
MFA at Net A Multiframe Alarm condition (2 consecutive errored multiframe alignment signals, or two
consecutive multiframes with all zeros in time-slot 16) has been detected on the network interface.
The condition is cleared when realignment (or time-slot 16 correction) occurs.

OOF at Prt
n
An Out Of Frame has been detected on data port Prt
n
(where
n
is the port number). This condition
only occurs if the synchronous data port’s Embedded Data Link (EDL) is enabled (only available for
2-port and 4-port E1 NTUs).
EER at Prt
n
The error rate of the received signal has exceeded the configured threshold for data port Prt
n
(where
n
is the port number). This condition only occurs if the synchronous data port’s Embedded
Data Link (EDL) is enabled (only available for 2-port and 4-port E1 NTUs). The condition is cleared
when the error rate falls below the synchronous data port’s configured threshold value.
PORT
SNMP Down The SNMP management link is in a down state for
PORT
(where
PORT
is COM or AUX). This
condition occurs if the
PORT
is configured for SNMP, and communication between the
management system and the E1 NTU is not currently possible for this port. For the AUX port, this
condition is detected only when a device reset or power-up occurs.
Selftest failed A failure was detected during the power-on self-test. Select STest (in the Stat branch) to display
more information about the failure.
DevFail
xxxxxxxx
An internal error has been detected by the operating software. An 8-digit code appears for use by
service personnel. The condition is cleared by resetting the device.
Download failed A download attempt was interrupted and failed to complete. The condition is cleared by resetting
the device.
Test in progress A test is currently active. Select Tstat (in the Stat branch) to display more test information.
Lp1/Lp2 Reversed The loop 1 and loop 2 connections on the HDSL network are reversed.
NTU Operational This message only appears if the unit is configured as an NTU and there are no valid alarm or
status messages.
LTU Operational This message only appears if the unit is configured as an LTU and there are no valid alarm or
status messages.
