T1 Filters

The Filter/Timer Configure message modifies approximately 100 combined timers and filters. There are approximately 14 signal scanning filters, 63 signal scanning timers, and 36 transmit signal timers for T1 trunk types.

Filter values are in 10 millisecond decimal units. If there is no value in a field, the filter does not apply.

Signaling Scanning Filters

Signal Scanning Filters (table below) define the duration that an expected signaling condition is expected to be valid before it is declared to have occurred.

Signaling Scanning Timers

Signal Scanning Timers (table below) define the minimum and maximum acceptable durations for signaling condition to exist from the point they are declared valid.

Timer values are in 10 millisecond decimal units. If there is no value in a field, the timer does not apply.
