NetPath 100 provides management access diagnostic test support.
NetPath 100 responds to and can issue T1 loopback codes, set operator-initiated loop-
backs, source BER Tests directed toward the T1 circuit or toward the DTE, and source
Frame Relay Test Packets toward the T1 circuit.
A block diagram of the test paths within the unit are shown in Figure 5-2.
