Description
DSX-1 signal is looped back to the network at the H2TU-R.
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 of the longest (maximum loss) span, measured
in dB.
The multiplexers of the H2TU-C and H2TU-R or the H2TU-C and first
regenerator are trying to establish synchronization over the HDSL2
loop of Span 1.
Armed to respond to Intelligent Repeater Loop (ILR) codes.
The H2TU-C receives no response from the H2TU-R. Therefore, the
integrity of the H2TU-R or the HDSL2 loop is questionable.
Framing bit error occurred at H2TU-C DSX-1 input.

"Appendix D - Product Support" on page
H2TU-C HDSL2 Loop Cyclical Redundancy Check (CRC) error.
A bipolar violation has been received at the DSX-1 input to the
H2TU-C-388.
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 H2TU-C-388 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 PWFD option
to off or by using 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 (or the H2TU-C and
first regenerator) are trying to establish contact with each other over
the HDSL2 loop of Span 1.
(a)
The DS1 line code setting: 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 of the H2TU-C-388.
The current margin threshold setting measured in dB.
The software version number (x.xx).
