       DESCRIPTION
       "The Cisco APS Extension MIB extends the Cisco APS MIB 
        in order to a) support path APS architectures and
        b) support interfaces other than SONET (e.g. Cisco
        CDL).

        For configuration and monitoring of APS for CDL interfaces,
        all objects and notifications in the Cisco APS MIB apply,
        with the exception of the following:
        - cApsStatusK1K2Rcv and cApsStatusK1K2Trans in
          cApsStatusEntry,
        - cApsConfigSdBerThreshold and cApsConfigSfBerThreshold
          in cApsConfigEntry,
        - cApsChanStatusSignalDegrades and
          cApsChanStatusSignalFailures in cApsChanStatusEntry,
        - cApsStatusFEPLFs in cApsStatusEntry,
        - cApsEventFEPLF.

        Whenever the description of an object in the Cisco APS MIB
        refers to a SONET LTE interface, this applies to CDL
        terminating interfaces as well. CDL interfaces have
        ifType values other than 'sonet'.

        For SONET path APS support, whenever the description of an
        object in the Cisco APS MIB refers to a SONET LTE
        interface, this applies to SONET PTE interfaces as well.
        SONET PTE interfaces have ifType values 'sonetPath'.

          There is no APS message exchange between the endpoints 
          of the associated channels.

        autoSelect  
 
          APS automatically selects a transport mechanism
          to send APS messages.  The following transport
          mechanisms are attempted, in the following order
          of priority:
           - apsChannel
           - dcc
           - osc

        dcc         

          APS messages are transmitted over the data communications 
          channels (DCCs) in the overhead of the associated channels.

        apsChannel
                    
          APS messages are transmitted in overhead bytes of the
          associated channels that are defined specifically
          to carry APS messages.

        ip
                  
          APS messages are transmitted over IP. The IP network can
          consist of any combination of data communication channels
          (DCCs), optical supervisory channels (OSCs), and
          out-of-band Data Communication Networks (DCNs).

        osc

        hopByHop

        This refers to linear APS, e.g. linear SONET APS, or hopByHop
        CDL APS. In a DWDM system, an APS channel may be associated
        with either an individual wavelength or an optical fiber.
        All APS channels within an APS group must be of the same type.
        Systems that support linear APS on an individual wavelength 
        basis, must assign an ifIndex to each such wavelength.

        endToEnd

        This refers to path APS, e.g. endToEnd CDL APS. In this
        configuration, each APS channel in the APS group is associated
        with an endToEnd user path. This codepoint does not apply to
        interfaces with an ifType value of 'sonet'.

       DESCRIPTION
       "The Y-cable configuration for the APS group associated with
        user channels.

        noYcable

        The APS channels in the APS group are not connected to an
        external Y-cable.

        ycable

        Two user-side interfaces (not necessarily SONET or CDL) are
        connected to an external y-cable and are grouped into an APS
        group for endToEnd APS. The received user signal is split
        in the y-cable coupler and is received on both the interfaces.
        However, only one interface must transmit toward the user at any
        given time. With cApsConfigYcable set to 'ycable', the
        cApsConfigSpan must be set to 'endToEnd'. There must be
        only two APS channels in an APS group with cApsConfigYcable
        set to 'ycable'.

        ycableXconnectCommon

        This refers to a configuration where two user-side interfaces
        are connected to an external y-cable. The two signals received
        on these interface are connected to the same cross connect in
        the switch. The switch fabric selects one of the two received
        signals, duplicates it, and forwards it to two network side
        interfaces grouped for 1+1 linear APS. The received signal from
        the network side is transmitted to only one user-side interface.
        cApsConfigSpan is ignored if cApsConfigYcable is set to
        'ycableXconnectCommon'. There must be only two APS channels in
        an APS group with cApsConfigYcable set to
        'ycableXconnectCommon'.

        This object may not be modified if the associated
        cApsConfigRowStatus object is equal to 'active'.

        If this object is set to 'ycable' or 'ycableXconnectCommon',

        cApsConfigRowStatus to 'notInService'.
