Local Internal Loopback
Local WinLink 1000 can be set to close an internal loopback to test
connection between the local and remote units, remote E1/T1 port and
its connection to the remote side user equipment. In this mode, data
coming from the remote user equipment is looped back to it (see
Figure 5-6 ). This loopback is initiated by an inband command sent
from a management station connected to the local unit.
