AUTOLP
This bit determines whether automatic Digital/Remote Loopback is enabled.
0: Automatic Digital/Remote Loopback is disabled. (default)
1: Automatic Digital/Remote Loopback is enabled. The corresponding channel will enter Digital/Remote Loopback when the acti-
vate IB code is detected in the transmit/receive path for more than 5.1 sec.; and will return from Digital/Remote Loopback when
the deactivate IB code is detected in the transmit/receive path for more than 5.1 sec.

DLP
This bit controls whether Digital Loopback is enabled.
0: Disable. (default)
1: Enable.

RLP
This bit controls whether Remote Loopback is enabled.
0: Disable. (default)
1: Enable.
