CISCO-ADSL-DMT-LINE-MIB

This MIB module serves as an enterprise-specific extension of
        the ADSL-LINE-MIB.  The structure of this MIB module shadows
        the structure of the ADSL-LINE-MIB, table for table.  The tables
        defined by this MIB module contain managed objects that meet the
        following criteria:
        
        1)  A managed object represents an attribute or characteristic
            specific to DMT (Digital Multi-Tone) modems.
        
        2)  The ADSL-DMT-LINE-MIB does not already contain a managed
            object representing the same information as a managed
            object.
        
        Observe that entries contained by the tables in this MIB module
        do not augment the corresponding entries in the ADSL-LINE-MIB,
        as every modem represented by the ADSL-LINE-MIB is not
        necessarily a DMT modem.
        
        Also observe that entries contained by the tables in this MIB
        module do not augment the corresponding entries in the
        ADSL-DMT-LINE-MIB, as this assumes that the ADSL-DMT-LINE-MIB
        defines tables that correspond to every table defined by the
        ADSL-LINE-MIB.  At this time, this assumption does not hold
        true.
        
        *** DEFINITIONS ***
        
        AGGREGATE DATA RATE
            Data rate transmitted by an ADSL system in any one
            direction.  This includes both net data rates and overhead
            used by the system, including:
                - EOC
                - AOC (ADSL Overhead Control channel)
                - CRC (Cyclic Redundancy Check) check bytes
                - fixed indicator bits for OAM (Operatings,
                  Administration, and Maintenance)
                - synchronization control bytes
                - capacity for bearer channel synchronization control
        
        BEARER CHANNEL
            A user data stream of a specific data rate that is
            transported transparently by an ADSL system over one of the
            simplex channels (i.e., AS0, AS1, AS2, or AS3) or one of the
            duplex channels (i.e., LS0, LS1, or LS2).
        
        BIN
            DMT line coding divides the frequency spectrum above the
            voice band of a line (i.e., 0-4 kHz) into 255 sub-carriers,
            each supporting 4.3125 kHz of bandwidth.  A 'bin' refers to
            a single sub-carrier.
        
        DATA SYMBOL RATE
            The average symbol rate (after allowing for the overhead of
            the sync symbol) at which symbols carrying data are
            transmitted; that is, 4000 symbols/second.
        
        DOWNSTREAM
            The flow of data in the direction from the ATU-C to ATU-R.
        
        LINE RATE
            The total data rate supported by a line; that is,
            (sum of b(i) for all i) * 4 kbps.
        
        MARGIN (also referred to as 'SNR margin')
            The difference between the SNR of the received signal and
            the SNR required to provide a BER of 10E-7.
        
        NET DATA RATE
            The data rate that is available for user data in any one
            direction; for the downstream direction this is the sum of
            the simplex and duplex bearer channel rates.
        
        SPLITTER
            Filters that separate the high frequency signals (ADSL)
            from the voice band signals; (frequently called POTS
            splitters even though the voice band signals may comprise
            more than just POTS).
        
        SYMBOL
            The number of bits the transmitter is capable of
            multiplexing and modulating over all the bins in a single
            signalling interval.
        
        SYMBOL RATE
            The rate at which all symbols, including the sync
            symbol, are transmitted; that is, (69/68) * 4000
            symbols/sec; contrasted with the data symbol rate.
        
        TOTAL DATA RATE
            The aggregate data rate (q.v.) plus Reed-Solomon FEC
            overhead.
        
        UPSTREAM
            The flow of data in the direction from the ATU-R to ATU-C.
