When the serial receiver detects a no-signal condition, the STATUS screen
indicates SIGNAL MISSING. Under this condition the line rate and active bits
readouts are blanked. See figure 2-7.
In Figure 2-7 loss of signal condition is indicated. Note that the FF and AP EDH
status says “missing” because of the absence of the error status packet.
