Event 2 COMMUNICATIONS LINE PROTOCOL ERROR DETECTED
REPLY REQUEST ERROR (UNISCOPE)
Description: This is a recoverable line protocol error that is generally caused by
faulty line or terminal hardware, or unacceptable electrical noise on the line. R8
contains the value 00E6. UNILPH generates this CENLOG. For more information on
UNILPH CENLOG entry descriptions, refer to Section 1 of this manual.
Action: If this error occurs for many terminals on the same line, check and repair the
line hardware and its electrical environment (including cables, modems, DCMs,
multiplexers).
If this error occurs for only one terminal, or only for terminals connected to the same
cluster controller, check and repair the terminal or cluster.
If this error occurs often enough to cause undue overhead to the system, issue an
NMS STOP command for the line, poll group, or terminal as applicable. When the
malfunctioning hardware has been taken offline, issue an NMS STRT command to
restore a normal operating environment.
