Controlled Slip Event
An asterisk (*) indicates that during this one-second interval one or
more controlled slip events occurred.
Active Payload Loop
An asterisk (*) indicates that during this one-second interval the CSU
was in a payload loopback condition (looping back toward the network
frames consisting of the received 192 information bits [the payload] plus
its own framing, CRC-6, and Data Link bits [the F-bits]). A period (.) in-
dicates that the CSU was not in a payload loopback condition.
Select PRM
This function causes the display to toggle between the Performance Report
Message (PRM) transmitted toward the network (OUTBOUND) and re-
