Figure 19: P10 Backplane Connector Pinout
Zone 2 contains the three connectors P20, P22 and P23. They carry the following types of
signals:
S Telecom clock signals (CLKx_)
S Base interface signals (BASE_)
S Fabric channel interfaces (FAB_)
Some of the pins provided by P20, P21 and P23 are defined as optional in the
AdvancedTCA specification and are unused on the blade. If the AdvancedTCA
specification defines these signals as input signals, they are terminated on the blade and
marked as "TERM_" in the following pinouts. In all other cases the pins are unconnected
and consequently marked as "n.c.".
