     DESCRIPTION

      "The initial revision of this module was published

       as RFC 1695. Key revisions include:

       o  Textual Conventions and OBJECT IDENTITIES have

          been moved to a separate MIB module.

       o  Applicability of objects to PVCs, SVCs and Soft

          PVCs has been clarified.

       o  DEFVAL clauses have been added.

       o  The relationship of ifIndex values with different

          layers and sublayers related to ATM has been

          clarified.

       o  atmTrafficQosClass has been deprecated

          and replaced with atmServiceCategory.

       o  atmInterfaceCurrentMaxVpiBits and

          atmInterfaceCurrentMaxVciBits have been added with

          a description on their relationship with other

          objects.

       o  atmInterfaceAddressType and atmInterfaceAdminAddress

          have been deprecated and replaced by

          atmInterfaceSubscrAddress.

       o  atmInterfaceTCAlarmState has been clarified.

       o  atmTrafficDescrParamIndexNext has been introduced

          in order to provide a manager a free

          atmTrafficDescrParamIndex value.

       o  The atmTrafficFrameDiscard capability has been added.

       o  A connection topology type (atmVpl/VclCastType) and

          a call control type (atmVpl/VclConnKind) have been

          added.

       o  aal2 has been added to atmVccAalType."

     DESCRIPTION

      "An entry in the VPL table.  This entry is

       used to model a bi-directional VPL.

       To create a VPL at an ATM interface,

       either of the following procedures are used:

       Negotiated VPL establishment

     (1) The management application creates

         a VPL entry in the atmVplTable

         by setting atmVplRowStatus to createAndWait(5).

         This may fail for the following reasons:

         - The selected VPI value is unavailable,

         - The selected VPI value is in use.

         Otherwise, the agent creates a row and

         reserves the VPI value 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 VPL.

    (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 VPL's traffic

         parameters through setting the

         atmVplReceiveTrafficDescrIndex and the

         atmVplTransmitTrafficDescrIndex values

         in the VPL 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 VPL by setting the

         the atmVplRowStatus to active(1).

         If this set is successful, the agent has

         reserved the resources to satisfy the requested

         traffic parameter values and the service category

         for that VPL.

     (4) If the VPL terminates a VPC in the ATM host

         or switch, the manager turns on the

         atmVplAdminStatus to up(1) to turn the VPL

         traffic flow on.  Otherwise, the

         atmVpCrossConnectTable  must be used

         to cross-connect the VPL to another VPL(s)

         in an ATM switch or network.

       One-Shot VPL Establishment

       A VPL may also be established in one step by a

       set-request with all necessary VPL parameter

       values and atmVplRowStatus set to createAndGo(4).

       In contrast to the negotiated VPL establishment

       which allows for detailed error checking

       (i.e., set errors are explicitly linked to

       particular resource acquisition failures),

       the one-shot VPL establishment

       performs the setup on one operation but

       does not have the advantage of step-wise

       error checking.

       VPL Retirement

       A VPL is released by setting atmVplRowStatus to

       destroy(6), and the agent may release all

       associated resources."
