Description
DSX-1 signal is looped back to the network at the H2TU-R SmartJack
module.
The Attenuation (A) message appears followed by xx, where xx is the
loop attenuation, measured in dB.
The multiplexers of the H2TU-C and H2TU-R are trying to establish
synchronization over the HDSL2 loop.
The multiplexers of the two devices are trying to establish
synchronization with each other, where n is the number of the span.
Armed to respond to Intelligent Repeater Loop (ILR) codes.
The H2TU-C receives no response from the H2TU-R and all HDSL2 loop
conditions are normal. Therefore, the integrity of the H2TU-R or the
HDSL2 loop is questionable.
Framing bit error occurred at H2TU-C DSX-1 input.
Flash download of firmware updates. Contact Customer Service for
update procedures (see
H2TU-C HDSL2 Loop Cyclical Redundancy Check (CRC) error.
A bipolar violation has been received at the DSX-1 input to the HiGain
Line Unit.
Indicates the power of the received HDSL2 signal relative to noise (S/N
with respect to 21.5 dB). Any value of 6 dB or greater is adequate for
reliable system operation.
The HiGain Line Unit is under control of the HMU-319 Network
management unit. In this state, the front-panel craft port and push
buttons are disabled.
HDSL2 span power has been turned off by setting the PWRF option to
off, or HDSL2 span power has been turned off by use of the A2LB
Intelligent Office Repeater (IOR) Power Down code.
Indicates that the HDSL2 loop is not grounded or shorted.
The transceivers of the H2TU-C and H2TU-R are trying to establish
contact with each other over the HDSL2 loop.
The transceivers of the two devices are trying to establish contact with
each other, where n is the number of the span.
(a)
The line code that H2TU-C-388 is receiving at its DSX-1 interface, if the
DS1 option is set to AUTO. Otherwise, it mimics either of the other two
DS1 line code settings, Alternate Mark Inversion (AMI) or Bipolar with
8-Zero Substitution (B8ZS).
Defines the type of frame pattern being received from the DSX-1:
SuperFrame (SF), Extended SuperFrame (ESF), Unframed (UNFR).
The current loop attenuation threshold setting measured in dB.
The list number xx.
The current margin threshold setting measured in dB.
The software version number (x.xx).
