Error Log Entries and Test to Clear Values
NOTE:
For TDM-BUS, an ON-BOARD alarm refers to a problem with the TDM-BUS
itself.
Notes:
a. The TDM Bus has been busied out by the technician. The error retires
when the technician releases the TDM Bus.
b. This error indicates the TDM Bus is corrupted. If the corruption was on the
Control Channel bus and this system has High or Critical Reliability, TDM
Bus maintenance automatically switches the control channel and/or tones
to the other bus. The same strategy applies if the corruption was on the bus
carrying the tones.
An aux data value of 0 indicates the last reported TDM Bus corruption was
on the Control channel bus.
