Description
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.
The multiplexers of the HLU, and HRU or first
doubler are trying to establish synchronization
over Loop 1 or Loop 2 of Span 1.
The multiplexers of the two devices on Span n are
trying to establish synchronization with each
other on Loop 1 or Loop 2, where n is the number
of the span.
Defines the type of frame pattern being received
from the DSX-1: SuperFrame (SF), Extended
SuperFrame (ESF), Unframed (UNFR), or NONE.
Displayed during System Settings review mode.
The transceivers of the HLU, and HRU or first
doubler are trying to establish contact with each
other on Loop 1 or Loop 2 of Span 1.
The transceivers of the two devices on Span n are
trying to establish contact with each other on
Loop 1 or Loop 2, where n is the number of the
span.
A system alarm has occurred, and has been
retired to an ACO condition by pressing the SEL
button on the HLU front panel.
The HLU is in a self-test mode. This occurs every
power On/Off cycle.
A minor alarm condition is in effect.
Indicates a short between the two HDSL pairs.
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.
Indicates an open circuit in the T/R of either HDSL
pair in Span 1.
