9.12.6.2
The transmit system data is looped back to the receive framer. This data is also encoded and output on TTIPn and
TRINGn. Signals at RTIPn and RRINGn are ignored. This loopback is conceptually shown in
Figure 9-30. Local Loopback
9.12.6.3
The outputs decoded from the receive LIU are looped back to the transmit LIU, not including the jitter attenuator in
the path. Remote Loopback 2 includes the jitter attenuator in the loopback path. The inputs from the transmit
framer are ignored during Remote Loopback 1.
9.12.6.4
The outputs decoded from the receive LIU are looped back to the transmit LIU, including the jitter attenuator. The
inputs from the transmit framer are ignored during Remote Loopback 2. This loopback is conceptually shown in
