Multipoint Digital Test Results
If the FAIL indicator remained Off for the entire test
interval, the Digital Test has passed and no problems have
been detected in either the DSUs or the network. If the
FAIL indicator has flashed sporadically, you may have
experienced network-related data errors. If the FAIL
indicator has flashed continuously, there is a hard failure
in either a DSU or in the network.
