Analog Loopback (ALOOP)
See
ALOOP operation disconnects the RTIP/RRING inputs from the line and routes the transmit
outputs back into the receive inputs. This tests the encoders/decoders, jitter attenuator, transmitter,
receiver and timing recovery sections.
In Hardware mode, ALOOP becomes active when the LLOOP pin is floating (i.e. Midrange). In
Host mode, setting bit CR2.EALOOP = 1 commands ALOOP. Note that ALOOP overrides all
other loopback modes.
