Operational Description
Data
During normal operation (i.e. transparent transmission and no test mode) the 2B+D
channels can be accessed via the IOM®-2 or the µP interface, if used. See section 4.2.1,
page 108 for details.
EOC
Basically the EOC channel can be accessed via MON-0 messages. However, internal
processing, manipulation and filtering of the EOC messages could take place
automatically, depending on the mode chosen. For details see section 4.2.2, page 110.
