equalizer are switched on permanently
Programmable deviation disabled
Programmable deviation enabled, i.e., the RxPLL reacts only
after a certain number of consequent deviations from the PLL
controlling range.
Transmitter (analog line driver) is disabled (e.g. for non-
transparent analog loops in LT-T)
Transmitter is enabled (e.g. for switching of transparent analog
loops in LT-S)
Loops disabled
Loop-back enabled. Channel_m transmit data is looped back
to the receive data path (either transparent or non-transparent
according to state of bit TX_EN). Depending on bit EXLP the
loop is closed internally or externally.
Operational mode
Channel_m in power-down mode (only the level detector in the
VIP receiver is in operational mode)
D-channel transmitted transparently, without any condition
D-channel transmitted transparently if no collision is detected
(E=D), if collision is detected (E
