LOOPBACK
There are four kinds of loopback:
Analog Loopback
Remote Loopback
Digital Loopback
Dual Loopback
Refer to Figure-1 for loopback location.
3.5.8.1 Analog Loopback
Analog Loopback is enabled by the ALP bit (b0, LOOP,...). The data
stream to be transmitted on the TTIPn/TRINGn pins is internally looped
to the RTIPn/RRINGn pins.
In Analog Loopback mode, the data stream to be transmitted is still
output to the line side, while the data stream received from the line side
is covered by the Analog Loopback data.
Anytime when Analog Loopback is set, the other loopbacks (i.e.,
Digital Loopback and Remote Loopback) are disabled.
In Analog Loopback, the priority of the diagnostic facilities in the
receive path is: pattern generation > looped data. AIS generation is
disabled in both the receive path and the transmit path. Refer to Figure-
