HLU-200 List 1E Diagnostic Messages

Message

Full Name

Description

FERR

Framing Bit Error 
Occurred

Framing bit error occurred at HLU T1 
input.

LBPV

Local Bipolar 
Violation

A bipolar violation has been received at the T1 
input to the HLU.

SIG1 or SIG2

Signal 1 or Signal 2

The HLU & HRU transceivers are trying to 
establish contact with each other.

S2(n)L1 or 2

Signal 2(n) Loop 1 or 
Loop 2

The transceivers of the first doubler and either 
the HRU or second doubler are trying to 
establish contact with each other on loops 1 or 
2 of span 2(n).

H1(2)ES

HDSL CRC Error 
Channel 1(2)

HLU HDSL Loop 1(2) CRC error.

ACQ1(2)

Acquisition 1(2)

The HLU & HRU multiplexers are trying to 
establish synchronization over each loop.

ARM

HiGain System 
ARMED

Armed to respond to Intelligent Repeater Loop 
Codes.

ACO

Alarm CutOff

A minor alarm has occurred, and been retired 
to an ACO condition, by pressing the SEL 
button on the HLU front panel.

Self Test

The HLU is in a self test mode.  This 
occurs every power ON/OFF cycle.

ALRM

Alarm Condition 
Exists

A minor alarm condition is in effect.

1=xx or 2=yy

HDSL Loop 
Margins

Indicates the relative S/N at each HDSL 
transceiving input port. Any value of ‘06’ or 
greater is adequate for reliable system 
operation.

PWR FEED 
SHRT

Power Feed Short

Indicates a short between the 2 HDSL pairs in 
span 1. This same message can occur with an 
HRU is drawing the correct amount of power 
over good cable pairs but cannot communicate 
with the HLU.

PWR FEED 
OPEN

Power Feed Open

Indicates an open circuit in both the T&R of 
either HDSL pair in span 1.
