         DESCRIPTION
                 "This table is deprecated in favour of using

                 ifStackTable.

                 Implementation of this table was optional.  It was
                 designed for those systems dividing a DS3/E3 into
                 channels containing different data streams that
                 are of local interest.

                 The DS3/E3 fractional table identifies which
                 DS3/E3 channels associated with a CSU are being
                 used to support a logical interface, i.e., an
                 entry in the interfaces table from the Internet-
                 standard MIB.

                 For example, consider a DS3 device with 4 high
                 speed links carrying router traffic, a feed for
                 voice, a feed for video, and a synchronous channel
                 for a non-routed protocol.  We might describe the
                 allocation of channels, in the dsx3FracTable, as
                 follows:
                 dsx3FracIfIndex.2. 1 = 3  dsx3FracIfIndex.2.15 = 4
                 dsx3FracIfIndex.2. 2 = 3  dsx3FracIfIndex.2.16 = 6

                 dsx3FracIfIndex.2.14 = 5  dsx3FracIfIndex.2.28 = 6
                 For dsx3M23, dsx3 SYNTRAN, dsx3CbitParity, and
                 dsx3ClearChannel  there are 28 legal channels,

                 For e3Framed there are 16 legal channels, numbered
                 1 through 16.  The channels (1..16) correspond
