-- the DS3/E3 Fractional Group
-- Implementation of this group is optional. It is 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. 3 = 3 dsx3FracIfIndex.2.17 = 6
-- dsx3FracIfIndex.2. 4 = 3 dsx3FracIfIndex.2.18 = 6
-- dsx3FracIfIndex.2. 5 = 3 dsx3FracIfIndex.2.19 = 6
-- dsx3FracIfIndex.2. 6 = 3 dsx3FracIfIndex.2.20 = 6
-- dsx3FracIfIndex.2. 7 = 4 dsx3FracIfIndex.2.21 = 6
-- dsx3FracIfIndex.2. 8 = 4 dsx3FracIfIndex.2.22 = 6
-- dsx3FracIfIndex.2. 9 = 4 dsx3FracIfIndex.2.23 = 6
-- dsx3FracIfIndex.2.10 = 4 dsx3FracIfIndex.2.24 = 6
-- dsx3FracIfIndex.2.11 = 4 dsx3FracIfIndex.2.25 = 6
-- dsx3FracIfIndex.2.12 = 5 dsx3FracIfIndex.2.26 = 6
-- dsx3FracIfIndex.2.13 = 5 dsx3FracIfIndex.2.27 = 6
-- dsx3FracIfIndex.2.14 = 5 dsx3FracIfIndex.2.28 = 6
-- For dsx3M23, dsx3SYNTRAN, dsx3CbitParity, and
-- dsx3ClearChannel there are 28 legal channels, numbered 1
-- through 28.
-- For e3Framed there are 16 legal channels,
-- numbered 1 through 16. The channels (1..16) correspond
-- directly to the equivalently numbered time-slots.
