Description
Signal from customer is looped back to the customer at the H2TU-R.
Dual loopback at the H2TU-C.
Signal from customer is looped back to the customer at H2TU-C.
DSX-1 signal is looped back to the network at the H2TU-C.
DSX-1 signal is looped back to the network at the H2TU-R.
Dual loopback 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 and all HDSL2 loop
conditions are normal. Therefore, the integrity of the H2TU-R or the
HDSL2 loop is questionable.
The H2TU-R does not have a frame ground connection.
Framing bit error has occurred at H2TU-C DSX-1 input.
H2TU-C HDSL2 Loop Cyclical Redundancy Check (CRC) error.
A bipolar violation has been received at the DSX-1 input to the H2TU-C.
Indicates the power of the received HDSL2 signal relative to noise (signal
to noise with respect to 21.5 dB). Any value of 6 dB or greater is
adequate for reliable system operation.
HDSL2 span power has been turned off by setting the PWFD 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 of Span 1.
(a)
The software version number of the H2TU-C.
The list number of the H2TU-C.
Defines the type of frame pattern being received from the DSX-1:
SuperFrame (SF), Extended SuperFrame (ESF), Unframed (UNFR), or
AUTO.
The DS1 line code setting: Alternate Mark Inversion (AMI) or Bipolar with
8-Zero Substitution (B8ZS).
The current loop attenuation threshold setting measured in decibels.
The current margin threshold setting measured in decibels.
