The PW-FR connection table.
Each entry in this table represents a FRoPW
connection operating in one-to-one mapping mode.
This table uses the same index as the generic
PW MIB's VC table. Therefore, each entry in
cpwVcFrTable has a mapping entry to the
generic PW MIB VC table associated by the
PW VC index.
An entry is created in this table by the agent
for every entry in the generic PW MIB VC table
with a VcType of 'frameRelay'.
