   dsx1FracTable OBJECT-TYPE

        STATUS  deprecated
        DESCRIPTION
               "This table is deprecated in favor of using
               ifStackTable.

               The table was mandatory for systems dividing a DS1
               into channels containing different data streams
               that are of local interest.  Systems that are
               indifferent to data content, such as CSUs, need
               not implement it.

               The DS1 Fractional table identifies which DS1
               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 an application managing a
               North American ISDN Primary Rate link whose
               division is a 384-kbit/s H1 _B_ Channel for video,

Top      Up      ToC       Page 57 
               a second H1 for data to a primary routing peer,
               and 12 64-kbit/s H0 _B_ Channels.  Consider that
               some subset of the H0 channels is used for voice
               and the remainder are available for dynamic data
               calls.

               We count a total of 14 interfaces multiplexed onto
               the DS1 interface.  Six DS1 channels (for the sake
               of the example, channels 1..6) are used for video,
               six more (7..11 and 13) are used for data, and the
               remaining 12 are in channels 12 and 14..24.

               Let us further imagine that ifIndex 2 is of type
               DS1 and refers to the DS1 interface and that the
               interfaces layered onto it are numbered 3..16.

               We might describe the allocation of channels, in
               the dsx1FracTable, as follows:
             dsx1FracIfIndex.2. 1 = 3  dsx1FracIfIndex.2.13 = 4
             dsx1FracIfIndex.2. 2 = 3  dsx1FracIfIndex.2.14 = 6
             dsx1FracIfIndex.2. 3 = 3  dsx1FracIfIndex.2.15 = 7
             dsx1FracIfIndex.2. 4 = 3  dsx1FracIfIndex.2.16 = 8
             dsx1FracIfIndex.2. 5 = 3  dsx1FracIfIndex.2.17 = 9
             dsx1FracIfIndex.2. 6 = 3  dsx1FracIfIndex.2.18 = 10
             dsx1FracIfIndex.2. 7 = 4  dsx1FracIfIndex.2.19 = 11
             dsx1FracIfIndex.2. 8 = 4  dsx1FracIfIndex.2.20 = 12
             dsx1FracIfIndex.2. 9 = 4  dsx1FracIfIndex.2.21 = 13
             dsx1FracIfIndex.2.10 = 4  dsx1FracIfIndex.2.22 = 14
             dsx1FracIfIndex.2.11 = 4  dsx1FracIfIndex.2.23 = 15
             dsx1FracIfIndex.2.12 = 5  dsx1FracIfIndex.2.24 = 16

               For North American (DS1) interfaces, there are 24
               legal channels, numbered 1 through 24.

               For G.704 interfaces, there are 31 legal channels,
               numbered 1 through 31.  The channels (1..31)
               correspond directly to the equivalently numbered
               time-slots."
