892 NTAK10 2.0 Mb DTI card
With the exception of the outpulsing signals and special signals, such as
Denmark’s Flash signal and Sweden’s Parking signal, the minimum duration
of any signal state is 100 ms. Some signal states can have a minimum
duration time that is longer than 100 ms.
The desired abcd bit pattern for a channel is output by the NTAK10, under
the control of the System Core card. The bit pattern to be transmitted is held
on the line for a minimum period of time. This time is specified in the same
message and ensures that the signal is detected correctly at the far end.
With the exception of the outpulsing signals and special signals, such as
Denmark’s Flash signal and Sweden’s Parking signal, the minimum duration
of any signal state is 100 msec. Some signal states may have a minimum
duration time that is longer than 100 msec.
