Front-Panel Display Messages - ADC PAIRGAIN HiGain HDSL2 Manual

Front Panel
Table 2 lists the front-panel display messages. The three- or four-character display reports the code of a pertinent
alarm, loopback, or diagnostic message and, in some cases, is followed by a second four-character message that
modifies the first message with a value or current configuration setting.

Table 2. Front-panel Display Messages
Description
A system alarm has occurred and has been retired to an ACO
condition by pressing the SEL button on the H2TU-C front panel.
A system alarm condition is in effect.
A system DS1 BER alarm is in effect and remains in effect until
cleared.
A system HDSL2 Block Error Rate alarm is in effect.
Indicates that the attenuation on the HDSL2 loop has exceeded the
maximum threshold value.
Indicates an AIS (all ones) pattern is being transmitted from the
local DS1 output port.
Indicates that no signal is detected at the DSX-1 input to the
H2TU-C. Causes a system alarm.
Indicates that the HDSL2 loop has lost synchronization.
The margin on HDSL2 loop has dropped below the threshold
(0 to 15 dB) as set by the operator.
The HDSL2 loop is grounded.
Indicates a line power open condition.
Indicates a short between the Tip and Ring of the HDSL2 pair.
H2TU-R PRM-FE BER threshold has been exceeded.
H2TU-R PRM-NE BER threshold has been exceeded.
Indicates an AIS (all ones) pattern is being received at the H2TU-R
DS1 input port.
Indicates that no signal is detected at the DS1 input to the H2TU-R.
Causes a system alarm.
Indicates an RAI alarm (yellow) from the CPE with errors from the
line unit or network.
Accompanies the LOSW alarm and identifies the span where the
LOSW alarm occurred.
Upon reception of an RAI (yellow alarm) from the CPE, the H2TU-R
sends RAI-CI towards the network if the network signal received at
the H2TU-R is clear. If the network signal is impaired (LOS, AIS, or
LOF), then the RAI is passed on to the network unaltered.
Accompanies the HBER, MAL, and LA alarm and indicates that the
alarm has occurred at the H2TU-C central office unit.
Accompanies the HBER, MAL, and LA alarm and indicates that the
alarm has occurred at the H2TU-R remote unit.
