This MIB is for managing information required to 
        route messages transported over Signalling System 
        No. 7 (SS7) Network via Cisco IP Transfer
        The Cisco IP Transfer Point (ITP) is a hardware 
        and software solution that transports SS7 traffic 
        using IP.  Each ITP node provides the functions
        necessary to act as a SS7 signalling point.  Each 
        signalling point is connected to other signalling 
        point using IP based or traditional TDM links.
        The relevant ITU documents describing this technology 
        are the ITU Q series, including ITU Q.700: Introduction
        to CCITT Signalling System No. 7 and ITU Q.701 
        Functional description of the message transfer part
        (MTP) of Signalling System No. 7.
        Definitions and overview:
        A route consists of one or more linksets used to transport
        MTP3 Message Signal Units(MSU) between signalling points.  
        A route is an association between a destination point 
        code(DPC) and a linkset, i.e., a linkset that can be used
        to send an MSU to the given DPC.
        A routeset is a set of routes to a given DPC.  Each route
        within a routeset is on a possible path toward the DPC.
        Each route within the routeset has associated with it a
        route priority.
        In the following simple configuration, two routes exist
        that can be used to transport MSUs from STP1 to STP4.
          ---------         STP1-STP2         --------- 
          - STP1  ----------------------------- STP2  - 
          ---------                           --------- 
              |                                   |
              | STP1-STP3               STP2-STP4 |
              |                                   |
          ---------         STP3-STP4         --------- 
          - STP3  ----------------------------- STP4  - 
          ---------                           --------- 
        Routeset on STP1 for DPC = STP4:
        A linkset is a set of signalling links connecting
        two signalling points.
        Combined Linkset: 
        Two linksets with equal number of links and capacity
        that form routes of equal priority to a given DPC are
        called Combined Linksets.  It is primarily used for
        load sharing and redundancy.  In the following, example,
        linksets 'SSP1-STP1' and 'SSP1-STP2' form a combined 
                SSP1-STP1             ---------
             |------------------------- STP1  -
             |                        ---------
            - - 
          -     -
         -  SSP1 -  
          -     -
            - - 
             |  SSP1-STP2            ---------
             |------------------------ STP2  -
        The routing of SS7 Message signalling Units(MSU) is based 
        on the DPC.  Message Signalling Units are sent from an
        originating point code(OPC) to DPC.  Each MSU will 
        traverse one or more linksets as it is routed to its 
        final destination.  When an MSU arrives at a signalling
        point and the DPC does not match the signalling point's
        point code the MSU must be directed toward the DPC.  Each
        signalling point has enough routing information to 
        determine which linkset should be used to transmit the
        MSU toward its final destination.
        Route statement:  
        Each ITP Signalling Point has route statements needed to
        determine which linkset should be used to transmit 
        message signalling units to destinations.  Each route
        statement consists of a destination, a priority and a
        linkset name.  The destination is specified as a 
        combination of DPC and mask.  The priority, also know
        as cost, is used to define the order in which the routes
        are selected.  The linkset name specifies which linkset
        to use to reach the destination.
        Route table:  
        Each ITP Signalling Point has a table of routes.  
        These route entries are used to determine which linkset
        should be selected to transmit message signalling units 
        to a given destination.  
        There are two basic type of routing.  The first type
        is fully-qualified and uses all bits of the target DPC.  
        The other type is summary routing that uses a subset
        of the bits in the target DPC and is used to represent 
        groups of point codes rather than a single point code.
        Example of route table entries.
        Example 1: variant = ITU
        DPC/MASK  Priority  Linkset-name
        --------  --------  -----------------------
        5.5.5/14  3         STP1-STP2
        5.5.5/14  7         STP1-STP3
        Description: Two route table entries that define a
        primary route using linkset 'STP1-STP2' and an alternate
        route using linkset 'STP1-STP3' to point-code 5.5.5.
        Example 2: variant = ITU
        DPC/MASK  Priority  Linkset-name
        --------  --------  -----------------------
        5.5.5/14  3         STP1-STP2
        5.5.5/14  3         STP1-STP3
        5.5.5/14  7         STP1-STP4
        Description: Two route table entries that define a
        combined linkset consisting of linkset 'STP1-STP2' and
        'STP1-STP3' to point code 5.5.5.  An alternate route is
        also defined using linkset 'STP1-STP4'.
        Example 3: variant = ANSI
        DPC/MASK  Priority  Linkset-name
        --------  --------  -----------------------
        5.5.0/16  3         STP1-STP2
        Description: A route table entry that defines routing
        to a cluster.  The cluster represents all point codes
        in the range from 5.5.0-5.5.255.
        Example 4: variant = ANSI
        DPC/MASK  Priority  Linkset-name
        --------  --------  -----------------------
        5.5.0/16  3         STP1-STP3
        5.5.5/24  3         STP1-STP2
        Description: The mixing of fully-qualified and summary
        route table entries allow for different routes to be
        defined for certain DPC in a cluster.  In this 
        configuration, the fully-qualified route will be the 
        primary and the summary route will act as a backup.
        Route table:  
        A group of route table entries used to route MSU for a 
        particular instance of a signalling point.
        A sample route table.
