PEB 24901
The usage of the two input pins, RES and TSP has the same effect as inputs RES and
SSP in the C/I-channel. They always overwrite the IOM-2 C/I-channel input.
3.4.1 Activation and Deactivation of Uk0 Transmission Lines
On Uk0, the exchange of control information is partially state oriented. Some signal
elements are given as long as no other information has to be transferred, other signal
elements have distinct durations.
3.4.1.1
Awake Protocol
To awake the Uk0 interface and the idle modules, an awake and an acknowledge signal
have been defined (see section 4.10)
Procedure for awaking one port of the Quad IEC DFE-T
After sending the awake signal, the awaking device waits for the acknowledge. After
12 ms, the awake signal is repeated, if no acknowledge has been recognized.
If an acknowledge signal has been recognized, the Quad IEC DFE-T waits for its
possible repetition (in case of previous coincidence of two awake signals). If no repetition
was detected, the IEC starts transmitting INFO U2 with a delay of 7 ms.
If such a repetition is detected, the Quad IEC DFE-T interprets it as an awake signal and
behaves like a device awoken by the far end.
Procedure in the Quad IEC DFE-T to be awoken
If a deactivated device detects an awake signal on Uk0, an acknowledge signal is sent
out. After that, the Quad IEC DFE-T waits for a possible repetition of the awake signal
(in case the acknowledge hasn’t been recognized). If no repetition is found, the awoken
IEC starts sending INFO U2 after 7 ms from detecting the awake signal. If a repeated
awake signal is found, the procedure in the awoken IEC starts again.
