Test access-monitor state
EX1397t
The monitoring configurations supported include:
• Single Facility Access Digroup, Monitor Equipment side (Single FAD,
MONE) see Figure 2-54
• Single Facility Access Digroup, Monitor Facility side (Single FAD,
MONF) see Figure 2-55
• Dual Facility Access Digroup, Monitor Equipment and Facility sides
(Dual FAD, MONEF) see Figure 2-56
Note: In Figure 2-54 to Figure 2-57 “equipment side” and “facility side”
shows the direction(s) of the connection under test.
Single FAD, MONE and Single FAD MONF
In a single FAD environment, only one direction of the signal can be monitored
at a time.
In the case of Single FAD, MONE, the monitored connection is from the
equipment side input to the facility side output, see A transmission path as
shown in Figure 2-54.
In the case of Single FAD, MONF, the monitored connection is from the
facility side input to the equipment side output, see B transmission path as
shown in Figure 2-55.
