TDM-CLK (TDM Bus Clock)
TDM Bus Clock Parameter Update Test (#151)
This test updates the following internal parameters on the Tone-Clock circuit pack:
Disable in-line duplication status messages.
Disable in-line subrate frame maintenance messages (TN768, TN780
only).
Set the PPM threshold at 60 PPM for TN768 and TN780. Set the PPM
threshold at 85 PPM for TN2182.
Enable PPM threshold switching
Set the number of slips to trigger loss of signal - currently 30 per 5
millisecond period
Enable the on-board synchronization switching algorithm (see above)
Enable holdover operation (TN2182 only).
This is not a test and will always pass without identifying or reporting any
Tone-Clock circuit pack errors
