Front Panel

 

 

Table 2 lists the front-panel display messages. The four-character display reports the code of an 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.

ALARM MESSAGES

 

 

ACO

Alarm Cutoff

A system alarm has occurred, and has been retired to an ACO

 

 

condition by pressing the SEL pushbutton on the H4TU-C front panel.

ALRM

Alarm Condition Exists

A system alarm condition is in effect.

DBER

DS1 Bit Error Rate

A system DS1 BER alarm is in effect and remains in effect until cleared.

DU1U or DU1D

Doubler 1 Upstream or Downstream

Precedes LA, HBR, and MAL and indicates the first H4D doubler HDSL4

 

Port

upstream or downstream interface.

DU2U or DU2D

Doubler 2 Upstream or Downstream

Precedes LA, HBR, and MAL and indicates the second H4D doubler

 

Port

HDSL4 upstream or downstream interface.

HBRx

HDSL4 Block Error Rate Loop 1 or

A system HDSL4 Block Error Rate alarm is in effect. (x indicates

 

Loop 2

Loop 1 or Loop 2.)

LAx

Loop Attenuation Loop 1 or Loop 2

The attenuation on the HDSL4 loop has exceeded the maximum

 

 

threshold value. (x indicates Loop 1 or Loop 2.)

LAIS

Line Alarm Indication Signal

Indicates an AIS (unframed all ones) pattern is being received or

 

 

transmitted at the H4TU-C DS1 input or output ports.

LLOS

Line (Unit) Loss of Signal

Indicates that no signal is detected at the DSX-1 input to the H4TU-C.

 

 

Causes a system alarm.

LOF

Loss of Frame

The DS1 input does not contain the ESF or SF frame pattern setting of

 

 

the FRMG option.

LOSW

Loss of Sync Word

Indicates that one of the HDSL4 loops has lost synchronization.

LRAI

Line RAI

Indicates an RAI alarm (yellow) from the CPE with an error-free signal

 

 

from the line unit or network. RAI signal is transmitted towards the

 

 

network.

MALx

Margin Alarm Loop 1 or Loop 2

The margin at Loop 1 or Loop 2 of the HDSL4 interface has dropped

 

 

below the threshold (0 to 15 dB) set by the operator. (x indicates

 

 

Loop 1 or Loop 2.)

PWR FEED GND

Power Feed Ground

The HDSL4 loop is grounded.

PWR FEED OPEN

Power Feed Open

Indicates a line power open condition.

PWR FEED SHRT

Power Feed Short

Indicates a short between Loop 1 and Loop 2 of the HDSL4 pair.

PRMF

Performance Report Messaging -

H4TU-R PRM-FE BER threshold has been exceeded at far end.

 

Far End

 

PRMN

Performance Report Messaging -

H4TU-R PRM-NE BER threshold has been exceeded at near end.

 

Near End

 

RAIS

Remote Alarm Indication Signal

Indicates an AIS (unframed all ones) pattern is being received or

 

 

transmitted at the H4TU-R DS1 input or output ports.

RLOS

Remote (Unit) Loss of Signal

Indicates that no signal is detected at the DS1 input to the H4TU-R.

 

 

Causes a system alarm.

RRAI

Remote RAI—Remote Alarm

 

Indication at the H4TU-R (Net signal

 

has errors.)

SPNn

Span Number

Indicates an RAI alarm (yellow) from the CPE with errors from the line unit or network. RAI-CI signal is transmitted towards the network.

Accompanies the LOSW alarm and identifies the span where the LOSW alarm occurred.

TUC

Transmission Unit Central Office

Precedes DBER, HBR, MAL, LA, and LOF alarms and indicates that the

 

 

alarm has occurred at the H4TU-C Central Office unit.

TUR

Transmission Unit Remote End

Precedes DBER, HBR, MAL, LA, and LOF alarms and indicates that the

 

 

alarm has occurred at the H4TU-R remote unit.
