{{reference}} This is the interface over which the test is to be performed. Number of repetitions of the ping test to perform before reporting the results. Timeout in {{units}} for the ping test. Result parameter indicating the number of successful pings (those in which a successful response was received prior to the timeout) in the most recent ping test. Result parameter indicating the number of failed pings in the most recent ping test. Result parameter indicating the average response time in {{units}} over all repetitions with successful responses of the most recent ping test. If there were no successful responses, this value MUST be zero. Result parameter indicating the minimum response time in {{units}} over all repetitions with successful responses of the most recent ping test. If there were no successful responses, this value MUST be zero. Result parameter indicating the maximum response time in {{units}} over all repetitions with successful responses of the most recent ping test. If there were no successful responses, this value MUST be zero. Asynchronous Transfer Mode (ATM) object that contains the {{object|Link}} interface and {{object|Diagnostics.F5Loopback}} diagnostics. ATM link-layer table (a stackable interface object as described in {{bibref|TR-181i2|Section 4.2}}). Models an ATM PVC virtual circuit and the ATM Adaption Layer (AAL). An ATM Link entry is typically stacked on top of either a {{object|##.DSL.Channel}} or a {{object|##.DSL.BondingGroup}} object. When an ''ATM Link'' interface is used, a lower-layer {{object|##.DSL.Channel}} interface MUST be configured with ATM encapsulation (see {{param|##.DSL.Channel.{i}.LinkEncapsulationUsed}}). Indicates the type of connection and refers to the complete stack of protocol used for this connection. {{bibref|RFC2684}} bridged Ethernet over ATM {{bibref|RFC2684}} routed IP over ATM {{bibref|RFC2364}} PPP over ATM {{bibref|RFC2225}} Classical IP over ATM Indicates if the CPE is currently using some auto configuration mechanisms for this connection. If this variable is {{true}}, all writable variables in this connection instance become read-only. Any attempt to change one of these variables SHOULD fail and an error SHOULD be returned. Destination address of this link, in the form "VPI/VCI" (e.g. "8/23" or "0/35"). Identifies the connection encapsulation that will be used. This flag tells if a checksum SHOULD be added in the ATM payload. It does not refer to the checksum of one of the ATM cells or AALX packets. In case of LLC or VCMUX encapsulation, this ATM checksum is the FCS field described in {{bibref|RFC2684}}. It is only applicable in the upstream direction. {{list}} Ordered list of VPI/VCI pairs to search if a link using the {{param|DestinationAddress}} cannot be established. In the form "VPI1/VCI1, VPI2/VCI2, ...". {{pattern}} Example: : ''0/35, 8/35, 1/35'' Describes the ATM Adaptation Layer (AAL) currently in use on the PVC. The current count of successfully transmitted cells. The current count of successfully received cells. Count of the ATM layer cyclic redundancy check (CRC) errors. This refers to CRC errors at the ATM adaptation layer (AAL). The AAL in use is indicated by the {{param|#.AAL}} parameter. The value of the {{param}} parameter MUST be 0 for AAL types that have no CRCs. Count of the number of Header Error Check related errors at the ATM layer. The ATM Link QoS object. Describes the ATM Quality Of Service (QoS) being used on the VC. Specifies the upstream peak cell rate in {{units}}. Specifies the upstream maximum burst size in {{units}}. Specifies the upstream sustainable cell rate, in {{units}}. The ATM Diagnostics object.
