             The purpose of this object is to point a network manager
             to the table in which the circuit was created as well as
             define the circuit on which the interface is defined.

             Valid tables for this object include the frCircuitTable
             from the Frame Relay DTE MIB(FRAME-RELAY-DTE-MIB), the
             frPVCEndptTable from the Frame Relay Service MIB

             It is recommended that the ifDescr of the circuit

             the operators that the particular interface represents
             only half the traffic on the circuit."

    ciCircuitStatus OBJECT-TYPE

        DESCRIPTION
            "The status of the current row.  This object is
             used to add, delete, and disable rows in this
             table.  When the status changes to active(1), a row
             will also be added to the interface map table below
             and a row will be added to the ifTable.  These rows
             SHOULD not be removed until the status is changed
             from active(1).  The value of ifIndex for the row that


             is added to the ifTable is determined by the agent
             and MUST follow the rules of the ifTable.  The value
             of ifType for that interface will be frDlciEndPt(193)
             for a frame relay circuit, atmVciEndPt(194) for an
             ATM circuit, or another ifType defining the circuit
             type for any other circuit.

             When this object is set to destroy(6), the associated
             row in the interface map table will be removed and the
             ifIndex will be removed from the ifTable.  Removing
             the ifIndex MAY initiate a chain of events that causes
             changes to other tables as well.

             The rows added to this table MUST have a valid object
             identifier for ciCircuitObject.  This means that the
             referenced object must exist and it must be in a table
             that supports circuits.

             The object referenced by ciCircuitObject MUST exist
             prior to transitioning a row to active(1).  If at any
             point the object referenced by ciCircuitObject does not
             exist or the row containing it is not in the active(1)
             state, the status SHOULD either age out the row or
             report notReady(3).  The effects transitioning from
             active(1) to notReady(3) are the same as those caused
             by setting the status to destroy(6).

             Each row in this table relies on information from other
             MIB modules.  The rules persistence of data SHOULD follow
             the same rules as those of the underlying MIB module.
             For example, if the circuit defined by ciCircuitObject
             would normally be stored in non-volatile memory, then
             the row SHOULD also be non-volatile."
