     --  ATM Interface Virtual Channel Link (VCL) Table

     -- This table contains configuration and state
     -- information of a bi-directional Virtual Channel
     -- Link (VCL) at an ATM interface.
     -- This table can be used to create, delete or modify
     -- a VCL that is terminated in an ATM host or switch.
     -- This table can also be
     -- used to create, delete or modify a VCL that is
     -- cross-connected to another VCL.

          DESCRIPTION
           "An entry in the VCL table. This entry is
            used to model a bi-directional VCL.
            To create a VCL at an ATM interface,
            either of the following procedures are used:

            Negotiated VCL establishment

          (1) The management application creates
              a VCL entry in the atmVclTable
              by setting atmVclRowStatus to createAndWait(5).
              This may fail for the following reasons:
              - The selected VPI/VCI values are unavailable,
              - The selected VPI/VCI values are in use.
              Otherwise, the agent creates a row and
              reserves the VPI/VCI values on that port.

          (2) The manager selects an existing row(s) in the
              atmTrafficDescrParamTable,
              thereby, selecting a set of self-consistent
              ATM traffic parameters and the service category
              for receive and transmit directions of the VCL.

         (2a) If no suitable row(s) in the
              atmTrafficDescrParamTable exists,
              the manager must create a new row(s)
              in that table.

         (2b) The manager characterizes the VCL's traffic
              parameters through setting the
              atmVclReceiveTrafficDescrIndex and the
              atmVclTransmitTrafficDescrIndex values
              in the VCL table, which point to the rows
              containing desired ATM traffic parameter values
              in the atmTrafficDescrParamTable.  The agent
              will check the availability of resources and
              may refuse the request.
              If the transmit and receive service categories
              are inconsistent, the agent should refuse the
              request.

          (3) The manager activates the VCL by setting the
              the atmVclRowStatus to active(1) (for
              requirements on this activation see the
              description of atmVclRowStatus).
              If this set is successful, the agent has
              reserved the resources to satisfy the requested
              traffic parameter values and the service category
              for that VCL.
          (4) If the VCL terminates a VCC in the ATM host
              or switch, the manager turns on the
              atmVclAdminStatus to up(1) to turn the VCL
              traffic flow on.  Otherwise, the
              atmVcCrossConnectTable  must be used
              to cross-connect the VCL to another VCL(s)
              in an ATM switch or network.

           One-Shot VCL Establishment

           A VCL may also be established in one step by a
           set-request with all necessary VCL parameter
           values and atmVclRowStatus set to createAndGo(4).

           In contrast to the negotiated VCL establishment
           which allows for detailed error checking
           (i.e., set errors are explicitly linked to
           particular resource acquisition failures),
           the one-shot VCL establishment
           performs the setup on one operation but
           does not have the advantage of step-wise
           error checking.

           VCL Retirement

           A VCL is released by setting atmVclRowStatus to
           destroy(6), and the agent may release all
           associated resources."
