There are several things besides the Current day and Recent day registers
that are required by the ANSI performance monitoring standard T1.231 but
that are not in the IETF trunkmibs.  Some other notable ones are failure
counts, protection switching statictics, and (for SONET ADMs) pointer
justification statistics (this last was added in T1.231-1997).  Some or
all of these things would be good candidates for supplemental trunk MIBs,
which have in fact been proposed some time ago.  Why not put PerfDayCount
(and any other TCs needed to support the supplemental trunk MIBs) in a
Supplemental-PerfHist-TC-MIB?
