Point-to-Point Digital Test Procedures
Follow the procedure in Table 3-3 to perform a Digital
Test (Point-to-Point).
Point-to-Point 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 flashed sporadically, you may have
experienced network-related data errors. If the FAIL
indicator flashed continuously, there is a hard failure in
either a DSU or the network.
