4. Diagnostics and error handling
4-8
When the CTEL master module is accessed via FMT/MMI, the
most current error for each I-port can be determined more pre-
cisely by means of an event code if the error is due to the con-
nected device.
A list with the relevant event codes can be found in the ap-
pendix A.2.
