Data flow when using the base interface
Data Flow
The AdvancedTCA standard is defined in PICMG 3.x specs, with the base definition
described in PICMG 3.0 (specifying the mechanics, airflow, power distribution, etc.).
One part of this specification describes the backplane, its connector types, and
connection topology.
For inter board communication, the following connection types are defined:
IXB2850 boards are designed to work with the base and fabric interfaces. The
backplane access module can be configured to work in dual-star (single or double port)
on the fabric interface.
Figure 4
• Base Interface: Defined as 1000BASE-T Ethernet working in a dual star topology;
• Fabric Interface: Only backplane topologies are defined because this interface type
each board is connected to two redundant fabric boards.
can be changed and its type is specified in subsequent PICMG 3.x specifications.
For example, PICMG 3.1, option 3 specifies the fabric interface as 1000BASE-BX
(fiber) Gigabit Ethernet. The fabric interface can be used in a dual-star topology.
