Link Aborts: A link abort occurs when the dataset, after sending a SABM 8 times, 
cannot get a valid response from the far end. Thus, a link abort often follows a link 
reset (specifically when the link reset happened because of many transmission line 
errors, set unplugged, or circuit switch path broken). 
Link aborts can also occur just after the dataset is sent to the B-channel. The dataset 
will send up to 64 SABMs in an attempt to achieve communication; if it does...

Power Up Self Test Causing the Dataset to be Busied Out: 
If a dataset fails its power 
up self test, it will be busied out. Maintenance logs will have two log entries: the busied 
out log and the power up self test failure reason. If a new dataset is installed that passes 
the power up self test, the device will be returned to service, without an installer using 
a maintenance command.

Sync: A synchronization signal is sent between the digital circuit and the set. The 
digital circuit monitors the physical line for the presence of this signal. Synchronization 
is lost when a set is unplugged or when a line is very noisy (external interference or 
bad connection). A loss of...

Retransmits: The retransmit counter increments each timeadigital circuit has to resend 
just sent information to a set. If the set has not responded to having received the just 
sent information, the circuit resends. 
This problem can be caused by: 
- a noisy line 
- bad set 
- bad circuit 
- software error (protocol violation). 
In most cases, a set will have no retransmits in a 24-hour period; however this counter 
can be influenced by the amount of traffic to the set. The more...

Explanation of error types: 
No Sync: 
A synchronization signal is sent between a digital circuit and a console. The 
digital circuit monitors the physical line for the presence of this signal. Synchronization 
is lost when a console is unplugged or when a line is very noisy (external interference 
or bad connection). A loss of synchronization increments the ‘no sync’ counter; 
however, maintenance reports are updated only after 25 occurrences. 
In normal operation, this counter...
