Description
Framing bit error occurred at HLU T1 input.
A bipolar violation received at the T1 input to the
HLU-231.
The HLU and HRU or first doubler transceivers are trying
to establish contact with each other on Loops 1 or 2 of
span 1.
The first doubler and either HRU or second doubler
transceivers are trying to establish contact with each
other on loops 1 or 2 of span 2.
The second doubler and either HRU or third doubler
transceivers are trying to establish contact with each
other on loops 1 or 2 of span 3.
The third doubler and either HRU or fourth doubler
transceivers are trying to establish contact with each
other on loops 1 or 2 of span 4.
The fourth doubler and HRU transceivers are trying to
establish contact with each other on loops 1 or 2 of
span 5.
The line unit and either the first doubler or the remote are
trying to establish synchronization with each other on
Loops 1 or 2 of span 1.
The first doubler and either HRU or second doubler
multiplexers are trying to establish synchronization with
each other on Loops 1 or 2 of span 2.
The second doubler and either HRU or third doubler
multiplexers are trying to establish synchronization with
each other on loops 1 or 2 of span 3.
The third doubler and either HRU or fourth doubler
multiplexers are trying to establish synchronization with
each other on loops 1 or 2 of span 4.
The fourth doubler and HRU multiplexers are trying to
establish synchronization with each other on loops 1 or 2
of span 5.
