7.4 Protocol Signal Bits
For in-depth HIPERFACE DSL
®
link investigations, a set of protocol signals can be monitored by
setting appropriate Watch Filters (see chapter 7.2.1). A protocol signal event is recorded if the
signal bit changes. Some bits are grouped together into multi-bit words. For them an event is
recorded if the record condition is met as indicated in the following table.
