The C/I-channel output and the transmitted Uk0 INFO are already specified by the state
diagrams; below they are only referred to, if within a state there are more than one of
them specified. In this case, the C/I-channel output and the transmitted Uk0 INFO
depend on the given inputs.
Ack. sent/received
Awake signal sent
Deac. acknowledged The Quad IEC DFE-T has received INFO U0, indicates this to
Deact. request rec.
Deactivating
Data transmission
If awaking, the Quad IEC DFE-T has received the acknowledge
signal. If being awoken the Quad IEC DFE-T has sent the
acknowledged. Anyway, the Quad IEC DFE-T waits for
possible repetition or time-out. The user data (B + B + D) on pin
DOUT is clamped to high to avoid undesired false data in the
D-channel during activation.
The Quad IEC DFE-T is awaking the Uk0 interface and waits
for the acknowledge or for the time-out after sending the awake
signal. The user data (B + B + D) on pin DOUT is clamped to
high.
the upstream unit and waits for DID, the permission to power
down. The user data (B + B + D) on pin DOUT is clamped to
high (except repeater modes).
The Quad IEC DFE-T has received INFO U0 or one of the
deactivating maintenance requests, RES or SSP. If it receives
SSP, the Quad IEC DFE-T sends a single pulse every 1 ms on
the line, otherwise INFO U0 is sent. The Quad IEC DFE-T
remains at least 0.5 ms in this state before accepting DIU to be
sure that it is already valid. The user date (B + B + D) on pin
DOUT is clamped to high (except repeater modes).
The Quad IEC DFE-T deactivates Uk0 sending INFO U0; it
remains at least 0.5 ms in this state to make sure that the
associate device on IOM-2 has recognized a change from a
possible DIU state to DA. The user data (B + B + D) on pin
DOUT is clamped to high (except repeater modes).
The transmission of user data is enabled (INFO U4/U5). If in 64
subsequent Uk0 frames the Barker-code is not found at the
expected position, the Quad IEC DFE-T gives out RSYD or
RSYU on the C/I-channel until it has resynchronized finding the
Barker-code on the same position in 4 subsequent frames.
The RDS counter and the adaption of receiver coefficients are
enabled even if RSYD/RSYU is given out.
