For T1 interfaces, specifies if alarm conditions are declared immediately or after a specific period of time when an alarm event (for example, out of frame) occurs. This keyword is not applicable for E1 interfaces.
NetworkInterface.T1E1[x].AlarmMode = mode
x = 0-(n-1) (0-based trunk number or range of trunk numbers where n equals the number of trunks on the board.)

The T1_G706 value is based on the G.706 ITU recommendation that signals be debounced. It does not specify an exact amount of time to wait.
