E&M Ports 7-11
7.3.2 Test Screen
The Test option facilitates testing and maintenance by allowing you to monitor and set the
status of the analog interface leads, and to monitor or set the value of the A, B, C, and D
signaling bits of all E&M circuits on that port. In cross-connect systems, the test option also
allows you to apply test patterns and tones towards the user and network sides of the system.
Figure 7-8 shows the E&M port Test Screen parameters,Table 7-3 lists some actions you can
perform from this screen, and Table 7-4 shows the settings for each parameter.
