ESCRIPTION
CREM
Customer Remote
Loopback
Signal from customer is looped back to customer at HLU-619.
NLOC
Network Local
Loopback
DSX-1 signal is looped back to DSX-1 at HLU.
CLOC
Customer Local
Loopback
Signal from customer is looped back to customer at HRU-612.
NREM
Network Remote
Loopback
DSX-1 signal is looped back to DSX-1 at HRU.
SMJK
Remote Smart-Jack
Loopback
DSX-1 signal is looped back to DSX-1 at HRU.
TLOS
Transmit Loss Of
Signal
HRU is in a logic loopback state, caused by a loss of its DS1 input
from the CI, when ENAbled at the HRU via its TLOS switch option.
FERR
Framing Bit Error
occurred
Framing bit error occurred at HLU DSX-1 input.
LBPV
Local Bipolar
Violation
A bipolar violation has been received at the DSX-1 input to the HLU-
619.
SIG
Signal
The HLU and HRU transceivers are trying to establish contact with
each other on the VHDSL loop.
ACQ
Acquisition
The HLU and HRU multiplexers are trying to establish
synchronization over the VHDSL loop.
HES
VHDSL CRC Error
VHDSL CRC error.
ARM
HiGain-2 System is
Armed
Armed and ready to respond to Intelligent Repeater loop codes.
ACO
Alarm CutOff
A minor alarm occurred and was retired to an ACO condition, after
pressing the SEL button on the HLU front panel.
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.
M=xx
VHDSL Loop Margin
Indicates the power of the received VHDSL signal on the loop relative
to noise. Any value of “06” or greater is adequate for reliable system
operation.
