Error Log Entries and Test to Clear Values
Notes:
a. The TDM bus has been busied out by the technician. The error will retire
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, TDM bus maintenance will automatically switch 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.
An aux data value of 1 indicates the last reported TDM bus corruption was
on the Non-Control channel bus.
c. This error indicates the TDM bus was switched to the other bus due to
TDM bus corruption. The aux data value is not meaningful and no action is
required. Look for other TDM-BUS errors to determine the cause of this
error.
