Remote FA4800 can be set to an internal loopback to test connection between the
local and remote units, the local E1/T1 port and its connection to the local side
user equipment. In this mode, data coming from the local FA4800 is looped back
to it (see Figure 5-9). This loopback is initiated from a management station
connected to the local unit.
