                dsx1JBZS refers the Jammed  Bit  Zero  Suppres-
                sion,  in  which  the  AT&T specification of at
                least one pulse every 8 bit periods is literal-

                each channel.  Thus, only seven bits per  chan-


                nel, or 1.344 Mbps, is available for data.

                dsx1B8ZS refers to the use of a specified  pat-
                tern  of  normal  bits  and  bipolar violations
                which are used to replace a sequence  of  eight

     The dsx1LineStatus is a bit  map  represented  as  a  sum,

     set.

     If the dsx1LoopbackState bit is set, the loopback  in  ef-
     fect can be determined from the dsx1LoopbackConfig object.

     -- the DS1 Fractional Group

     -- Implementation of this group is mandatory for those
     -- 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. 6 = 3    dsx1FracIfIndex.2.18 = 10

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

     --      For G.704 interfaces, there are 31 legal channels,
