790 NTAK10 2.0 Mb DTI card
Outgoing supervisory signals
The desired ABCD bit pattern for a channel is output by the NTAK10,
under the control of the system controller 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 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.
