Loopbacks Overview
OCU-DP Loopbacks
These loopbacks may be activated by the network or manually (CLI). These loopbacks
are OCU, CSU, and DSU. The Network may activate each loopback by sending
latching or non-latching code sequences. The OCU-DP card may be configured to
allow detection of each sequence for each loopback.
