DESCRIPTION

::= { modules 41 }

-- This group consists of a table of BRI interfaces indexed
-- by ifIndex which provide MIB objects not given in a convenient form by
-- other standard MIBs. There is also a BRI channel MIB indexed by ifIndex
-- and channel index which gives information about the channels on the
-- interface.

-- The BRI interface table. Each entry is a BRI interface on the router.
