10.1.4 Network Loopback
When ENLOOP is enabled (set ENLOOP in CR2, or float the ENLOOP pin), the in-band loop code
detector is enabled. The receiver detects the in-band loop code patterns (00001 = loop up and
001 = loop down) present in the inbound data. The detectors detect both framed and unframed loop codes.
When the loop-up pattern is detected and present for 5 seconds, the device invokes remote loopback.
ENLOOP is dropped when:
1) The in-band loop-down pattern is present for 5 seconds.
2) RLB is activated.
3) ALB is activated.
10.1.5 Dual Loopback
Dual loopback is the simultaneous enabling of RLB and LLB. If the jitter attenuator is enabled and, when
both loopback paths are enabled, the jitter attenuator is placed in the local loopback path.
