Message
Full Name
Description
FERR
Framing Bit Error
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-D41.
SIG
Signal
The HLU and HRU, or first doubler transceivers, are trying to
establish contact with each other on Span 1.
S2
Signal 2
The first doubler and either HRU or second doubler transceivers
are trying to establish contact with each other on Span 2.
S3
Signal 3
The second doubler and HRU transceivers are trying to establish
contact with each other on Span 3.
ACQ
Acquisition
The HLU and HRU or first doubler multiplexers are trying to
establish synchronization on Span 1.
A2
Acquisition 2
The first doubler and either HRU or second doubler
multiplexers are trying to establish synchronization with each
other on Span 2.
A3
Acquisition 3
The second doubler and HRU multiplexers are trying to
establish synchronization with each other on Span 3.
HES
HDSL CRC Error
HLU HDSL Loop 1 CRC error.
SELF TEST
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
HDSL Loop Margin
Indicates the power of the received HDSL signal on each loop
relative to noise. Any value of 06 or greater is adequate for
reliable system operation.
PWR FEED SHRT
Power Feed Short
Indicates a short on the HDSL span. This same message can
occur with an HRU that 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 on the HDSL span.
PWR FEED OFF
Power Feed Off
HDSL span power has been turned off by setting the PWFD
option to Disable.
BAD RT?
No response from HRU
The HLU does not receive any response from the HRU. Thus,
the HRU or span may be at fault.
VER
HLU Software Version #
Displayed during the System Settings review mode or by pressing
the Mode Setup button for three seconds.
LIST 0xL
HLU’s List #
Displayed during System Settings review mode defined above.
FRM
Frame:SF,ESF,UNFR,NONE
Defines the type of frame pattern being received from the DSX-1.
Displayed during System Settings mode defined above.
LOSW
Loss of Sync Word
Indicates that the HDSL loop has lost sync.
RLOS
Remote Loss of Signal
Indicates that no signal is detected at the T1 input to the HRU.
DS1
DS1 BPV errors
Indicates that the number of BPVs at the HLU or HRU DS1
inputs have exceeded the 24 hour ES threshold.
MAL
Margin Alarm
The margin on the HDSL loop has dropped below the user-
defined threshold (1 to 15 dB) set by the user.
