Coding of the Uk0-Signal Elements
Upstream from NT to LT
INFO U1W:
16 times
ternary + + + + + + + + – – – – – – – –
A tone of:
Frequency: 7.5 kHz
Width: 2.13 ms
INFO U1A:
Binary continuous "0"
before scrambling.
No frame, ternary "0"
instead of Barker code
INFO U1:
Binary continuous "0"
before scrambling.
Frame (Transmitting Barker code)
INFO U3:
Binary continuous "1"
before scrambling.
Frame (Transmitting Barker code)
INFO U5:
Binary data from the
digital interface.
Frame (Transmitting Barker code)
INFO U0:
Ternary continuous "0"
No frame, no signal level
4.9
The Quad IEC DFE-T detects an INFO U1, U2 or U3 if the continuous binary data is
found on the descrambler output after 8 subsequent Uk0 frames. These INFOs are
detected after 8 to 9 ms.
INFO U4H is recognized if the NT finds 16 subsequent binary 1s in the data stream.
INFO U0 is recognized if the Quad IEC DFE-T finds one complete frame with continuous
zero level.
Detection of INFO U0, U1, U2, U3 and U4H
