             for the PVC segment end-points in the
             frPVCEndptTable must first be created.  Next, the
             frPVCConnectTable is used to associate the Frame
             Relay PVC segment end-points.  In order for the
             manager to have the necessary error diagnostics,
             the frPVCEndptRowStatus object must initially be
             set to `createAndWait'.  While the

             `createAndWait' state, the manager can set each
             columnar object and get the necessary error
             diagnostics.  The frPVCEndptRowStatus object may
             not be set to `active' unless the following
             columnar objects exist in this row:

 -- The Frame Relay PVC Connection Group

 -- The Frame Relay PVC Connection Group
 -- is used to model the bi-directional
 -- PVC segment flows;
 -- point-to-point PVCs, point-to-multipoint
 -- PVCs, and multipoint-to-multipoint
 -- PVCs.

 -- This table has read-create access and
 -- is used to associate PVC end-points
 -- together as belonging to one connection.
 -- The frPVCConnectIndex is used to associate
 -- all the bi-directional flows.
 -- Not all implementations will support the
 -- capability of creating/modifying/deleting
 -- PVCs using SNMP as a feature of Frame Relay
 -- CNM service.

 -- Once the entries in the frPVCEndptTable
 -- are created, the following step are used
 -- to associate the PVC end-points as belonging
 -- to one PVC connection:
 -- 1). Obtain a unique frPVCConnectIndex
 --     using the frPVCConnectIndexValue object.
 -- 2). Connect the PVC segment endpoints together
 --     with the applicable frPVCConnectIndex value
 --     obtained via
 --     frPVCConnectIndexValue.
 --     The entries in this table are created by using
 --     the frPVCConnectRowStatus object.
 -- 3). The agent will provide the value of the
 --     corresponding instances of
 --     frPVCEndptConnectIdentifier with the
 --     the frPVCConnectIndex value.
 -- 4). Set frPVCConnectAdminStatus to `active' in all
 --     rows for this PVC segment to
 --     turn the PVC on.

 -- For example, the Frame Relay PVC Connection Group
 -- models a bi-directional, point-to-point PVC segment
 -- as one entry in this table.

 -- Frame Relay Network                  Frame Relay Network
 --  Low Port ____________________________________ High Port
 --          |                                   |
 --    ______| >> from low to high PVC flow   >> |____________
 --          | << from high to low PVC flow   << |
 --          |___________________________________|
 --

 -- The terms low and high are chosen to represent numerical
 -- ordering of a PVC segment's endpoints for representation
 -- in this table.  That is, the endpoint with the lower value
 -- of ifIndex is termed 'low', while the opposite endpoint
 -- of the segment is termed 'high'.
 -- This terminology is to provide directional information;
 -- for example the frPVCConnectL2hOperStatus and
 -- frPVCConnectH2lOperStatus as illustrated above.

 -- If the Frame Relay Connection table is used to model
 -- a unidirectional PVC, then one direction (either from low to high
 -- or from high to low) has its Operational Status equal to down.

 -- A PVC segment is a portion of a PVC
 -- that traverses one Frame Relay Network, and
 -- a PVC segment is identified
 -- by its two end-points (UNI/NNI logical port index
 -- value and DLCI index value)
 -- through one Frame Relay Network.
