      "This is the MIB module for the support of Channel Bonding
    Protocol for the Cable Modem Termination System (CMTS).
    
    Wideband DOCSIS is a method of increasing downstream
    bandwidth by simultaneously transmitting DOCSIS data
    over multiple RF channels. This DOCSIS data is
    organized as a sequence of 188-byte MPEG-TS data packets.
    
    A Wideband CMTS (WCMTS) is a CMTS that also transmits
    Wideband MPEG-TS packets.
    
    An Edge QAM (Quadrature Amplitude Modulation) device is one
    which provides the QAM and used to couple the Wideband MPEG-TS
    packet onto the HFC plant.
    
    A Wideband Cable Modem (WCM) is a CableModem (CM) that
    is able to receive Wideband MPEG-TS packets.
    
    A wideband channel or Bonded Group (BG) is a logical
    grouping of one or more physical RF channels over which
    MPEG-TS packets are carried. Wideband channel carries DOCSIS
    bonded packets encapsulated in MPEG-TS packets from a
    WCMTS to one or more WCMs.
    
    Packets outgoing from WCMTS to the WCM are formatted with
    the DOCSIS Header. The DOCSIS packets are then formatted into
    MPEG-TS data packets. These are 188 byte MPEG packets
    containing the DOCSIS information.
    Within DOCSIS Header of the WB Channel there is an extended
    header called, DOCSIS Bonding Extended Header, the format of
    which is shown below:
    
     --------------------------------------------------------
    |  ----------------------------------------------------  |
    | |  TYPE | LEN |       BSID           |      SEQ        |
    |  ----------------------------------------------------  |
    | |    byte 0   |     byte 1-2         |    byte 3-4     |
    |--------------------------------------------------------|
                  DOCSIS Bonding Extended Header
    
    BSID is the Bonding Service IDentifier, it defines a sequence
    number for a Wideband channel. It is used by the WCM to
    re-sequence packets received over downstream channels to
    maintain packet order. SEQ is per service flow sequence number.
    Whereas TYPE is the type of the Bonding Extended Header and LEN
    specifies its length.
    
    A Narrowband Channel is a standard DOCSIS downstream channel
    which contains exactly one RF channel.
    The wideband protocol utilizes the existing narrowband
    downstream channel for carrying the MAC management and
    signaling messages and the associated narrowband upstream
    for return data traffic and signaling.
    
    The channel bonding protocol supports multiple wideband
    bonded groups. This will allow the WCM to listen to multiple
    bonded groups at the same time. This would support (for example)
    multicast video being sent to a CPE device on the LAN side of
    the WCM in addition to standard DOCSIS data.
    
    Channel Bonding allows two types of Bonding Group (BG) interfaces.
    These are Secondary BG interface and non-Secondary BG
    interface. The Secondary BG interfaces will carry the multicast
    traffic, whereas, the non-Secondary BG interface will carry the
    non-multicast traffic.
    This MIB also allows for configuration of the RF channels
    on the WCMTS, as well as the association between the RF and
    narrowband downstream channels with the BG channel.
    
    Fiber Node is an optical node which terminates the fiber based
    downstream signal as an electrical signal onto a coaxial RF cable.
