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