BH GSO ISO/IEC 9314-21:2016 Scope
This part of ISO/IEC 9314 defines a conformance test of the PHY functions in a path through
an FDDI node. Figure 1 is a functional block diagram of an FDDI path. The path contains the
necessary functions to repeat (that is decode and retransmit) frames through an FDDI node
The PHY Repeat Filter is optional when there is a MAC in the repeat path. If there is no MAC
in the repeat path, then the function is implemented in PHY. This test standard makes no
assumption about the presence or absence of MAC on the path and is intended to operate
with or without a MAC. It tests the repeat filter function wherever it is located. However, the
results of some tests may be slightly different if a MAC is present.
