row 
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.
