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.

TS16 microprocessor
The functions of this microprocessor include:
•
receiving signaling messages supplied by the DS-30X microprocessor,
decoding these messages, and taking subsequent actions
•
transmitting messages to the DS-30X microprocessor
•
handling PPM
•
updating the TS16 select RAM and TS16 data RAM
•
providing outpulsing
•
receive data from the change-of-state microprocessor
