4 – ATL CSU/DSU Local Loopback
Enabling this activates the local loopback function of the ATL CSU/DSU link module.
When in local loopback, the ATL CSU/DSU link module will create an internal loopback on both the digital interface
and the analog interface. The test results shown here indicate traffic that is generated by the router and looped back by
the digital interface of the ATL CSU/DSU link module.
Link Interface Type: ATL CSU/DSU 56 Kbps
