8.11.5.3
The outputs decoded from the receive LIU are looped back to the transmit LIU. The inputs from the transmit framer
are ignored during a remote loopback. This loopback is conceptually shown in
Figure 8-18. Remote Loopback
8.11.5.4
The inputs decoded from the receive LIU are looped back to the transmit LIU. The inputs from the transmit framer
are looped back to the receiver with the optional jitter attenuator. This loopback is invoked if RLB and LLB are both
set in the LIU Maintenance Control register (LMCR). This loopback is conceptually shown in
Figure 8-19. Dual Loopback
