                value as ifIndex.  Otherwise, number the
                dsx1LineIndices with an unique identifier

                dsx1JBZS refers the Jammed Bit Zero Suppression,
                in which the AT&T specification of at least one
                pulse every 8 bit periods is literally implemented
                by forcing a pulse in bit 8 of each channel.
                Thus, only seven bits per channel, or 1.344 Mbps,
                is available for data.

                dsx1B8ZS refers to the use of a specified pattern
                of normal bits and bipolar violations which are
                used to replace a sequence of eight zero bits.

                ANSI Clear Channels may use dsx1ZBTSI, or Zero
                Byte Time Slot Interchange.

                E1 links, with or without CRC, use dsx1HDB3 or
                dsx1AMI.

                dsx1AMI refers to a mode wherein no zero code
                suppression is present and the line encoding does
                not solve the problem directly.  In this
                application, the higher layer must provide data
                which meets or exceeds the pulse density
                requirements, such as inverting HDLC data.

                dsx1B6ZS refers to the user of a specifed pattern
                of normal bits and bipolar violations which are
                used to replace a sequence of six zero bits.  Used
                for DS2."

        MAX-ACCESS not-accessible
        STATUS deprecated
        DESCRIPTION
               "This table is deprecated in favour of using
                  ifStackTable.

                  The table was mandatory for systems dividing a DS1
                  into channels containing different data streams
                  that are of local interest.  Systems which 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,
                  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 are 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 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."
