        DESCRIPTION
                "This MIB module is intended for the management of network clock 
                distribution and the Network Clock Distribution Protocol (NCDP) 
                in Cisco MGX ATM switches. This MIB allows enabling automatic network 
                clock configuration and distribution as well as configuration of 
                manual clock sources.  

                NCDP allows automatic distribution of network clocking sources
                in the network. A spanning network clock distribution tree is
                constructed by each node in the network and each node is 
                synchonized to one single 'master' clock reference. 

                A source of network clock for the device may be an oscillator
                local to the device or a Building Integrated Timing Supply (BITS)
                port or an interface that supports synchronous clock recovery.

                An 'index'('cwnClockSourceIndex') is assigned by the NCDP
                protocol entity in the managed system to identify each available 
                source of network clock on the managed system."

                'lossOfActivity' indicates that the clock source was changed
                because the network clocking hardware detected a loss of

                'ncdpRestructure' indicates that the NCDP entity has changed

                clock identified by 'cwnClockSourceIndex' and used by 
                the managed system when the value of 
                'cwnDistributionMethod' is 'ncdp'. 
        
                The managed device selects one entry in this table to
                advertise as the best available clock source for the device.

                Cooperating NCDP protocol entities select the best available
                clock source among those advertised within the cooperating
                group and build a clock distribution tree rooted at that clock
                source.  When the value of 'cwnRootClockSource' is used 
                as an index into this table and the indicated clock source has
                'cwnAtmSourceBestClockSource' with value 'true' then the indicated
                clock source is the root of some clock distribution tree.  If
                only one such root exists on all participating devices in the
                network, then it is the root of a network wide clock
                distribution tree.

                When the managed system initializes it creates a row for the
                device's default source of network clock.  This row cannot be
                destroyed by a management station.  Within this row a write
                operation is only allowed on the 'cwnAtmSourcePriority' object.
                The status of this row is always active. The default source
                can always be found by issuing a  read operation on the row within
                'cwnManualSourceTable' that has 'default' as the value 
                of 'cwnManualSourcePriority'. 

                The other rows are created or destroyed by a management station or
                through the device's local management interface when a source
                of network clock is configured or removed.  

                The values of 'cwnAtmSourcePriority', 'cwnAtmSourceStratum' and
                'cwnAtmSourcePRSReference' collectively describe a source of network
                clock. They are the three components of a vector used as an
