This group contains the provisionable traffic attributes for a control channel.

An entry in the atmIfUniSigVcdProvTable.

This attribute specifies the type of traffic management which is applied to both the transmit and receive direction of this connection as defined in the ATM Forum. The trafficDescType determines the number and meaning of the parameters in the trafficDescParm attribute. Enumeration: 'n8': 8, 'n3': 3, 'n6': 6, 'n7': 7.

This attribute specifies the ATM service category for both directions of the connection. The constantBitRate service category is intended for real time applications, that is those requiring tightly constrained delay and delay variation, as would be appropriate for voice and video applications. The consistent availability of a fixed quantity of bandwidth is considered appropriate for CBR service. Cells which are delayed beyond the value specified by CellTransfer Delay are assumed to be of significantly reduce value to the application. The rtVariableBitRate service category is intended for real time applications, that is those requiring tightly constrained delay and delay variation, as would be appropriate for voice and video applications. Sources are expected to transmit at a rate which varies with time. Equivalently, the source can be described as 'bursty'. Cells which are delayed beyond the value specified by CTD are assumed to be of significantly reduced value to the application. Real time VBR service may support statistical multiplexing of real time sources. The nrtVariableBitRate service category is intended for non-real time applications which have bursty traffic characteristics and which can be characterized in terms of a PCR, SCR, and MBS. For those cells which are transferred within the traffic contract, the application expects a low cell loss ratio. For all connections, it expects a bound on the mean cell transfer delay. Non-real time VBR service may support statistical multiplexing of connections. The unspecifiedBitRate service is intended for non-real time applications; that is, those not requiring tightly constrained delay and delay variation. UBR sources are expected to be bursty. UBR service supports a high degree of statistical multiplexing among sources. UBR service does not specify traffic related service guarantees. No numerical commitments are made with respect to the cell loss ratio experienced by a UBR connection, or as to the cell transfer delay experienced by cells on the connection. Enumeration: 'constantBitRate': 1, 'unspecifiedBitRate': 0, 'rtVariableBitRate': 2, 'nrtVariableBitRate': 3.

This attribute specifies the quality of service for both the forward and backward direction for this connection. Class 1 supports a QOS that meets Service Class A performance requirements (Circuit emulation, constant bit rate video).

Class 3 supports a QOS that meets Service Class C performance requirements (Connection-Oriented Data Transfer). Class 4 supports a QOS that meets Service Class D performance requirements (Connectionless Data Transfer). Class 0 is the unspecified bit rate QOS class; no objective is specified for the performance parameters. Enumeration: 'n0': 0, 'n1': 1, 'n2': 2, 'n3': 3, 'n4': 4.

This attribute specifies whether this connection uses traffic shaping when transmitting traffic to the ATM interface. When sameAsCa is selected, traffic shaping for this connection is based on the trafficShaping attribute of the connection's service category component under the AtmIf CA. If the service category has traffic shaping enabled, then traffic shaping is enabled for the connection. Note that enabling traffic shaping may have no effect under certain cases. These cases are listed in the description of the trafficShaping operational attribute, which is under the Vcc Tm and Vpc Tm components. When disabled is selected, traffic shaping for this connection is disabled. Enumeration: 'disabled': 1, 'sameAsCa': 2.

This attribute only applies when this connection is unshaped. This attribute specifies the transmit queueing method for this connection if it is unshaped. Refer to the unshapedTransmitQueueing attribute under the AtmIf CA service category subcomponent for more details on the meaning of this attribute. When this attribute is set to sameAsCa, the transmit queueing method for the connection is based on the unshapedTransmitQueueing attribute of the connection's service category component under the ConnectionAdministrator. When this attribute is set to common, transmit traffic on this unshaped connection is destined for the common queue. The value sameAsInterface is for migration from previous software releases, but should no longer be used Enumeration: 'sameAsCa': 3, 'common': 1.

This attribute specifies whether this connection enforces usage parameter control when receiving traffic from the ATM interface. When sameAsCa is selected, UPC for the connection is based on the usageParameterControl attribute of the connection's service category component under the ConnectionAdministrator. If the service category has UPC enabled, then UPC is enabled for the connection. Note that enabling UPC may have no effect under certain cases. These cases are listed in the description of the usageParameterControl operational attribute, which is under the Vcc Tm or Vpc Tm component. When disabled is selected, UPC for this connection is disabled. The value sameAsInterface is for migration from previous software releases, but should no longer be used Enumeration: 'disabled': 1, 'sameAsCa': 2.

This attribute is a vector of five traffic parameters whose meanings are defined by the trafficDescType attribute. The values of peak cell rate (PCR), sustained cell rate (SCR) and requested shaping rate are expressed in cell/s. Maximum burst size (MBS) is expressed in cells. CDVT is expressed in microseconds. The values of PCR, SCR, MBS and CDVT are used for connection admission control (CAC). The value of CDVT is only used for connections where the atmServiceCategory is constantBitRate. For all other values of atmServiceCategory, CDVT is ignored. The values of PCR, SCR and requested shaping rate are used to determine the actual shaping rate where traffic shaping is enabled. When trafficDescType is 3, parameter 1 represents the PCR for CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and parameter 5 represents the requested shaping rate. A non-zero value in parameter 5 overrides any value in parameter 1. This result is used as the PCR. Parameter 1 must be non-zero. Parameters 2 and 3 must be zero. When trafficDescType is 6, parameter 1 represents the PCR for CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and parameter 5 represents the requested shaping rate. A non-zero value in parameter 5 overrides any value in parameter 1. This result is used as the PCR. Parameters 1, 2, and 3 must be non-zero. Parameter 1 must be greater than or equal to parameter 2. Parameter 5 must either be zero (unused) or greater than or equal to parameter 2. When trafficDescType is 7, parameter 1 represents the PCR for CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for CLP equal to 0 with cell discard; parameter 3 represents the MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT; and parameter 5 represents the requested shaping rate. A non-zero value in parameter 5 overrides any value in parameter 1. This result is used as the PCR. Parameters 1, 2, and 3 must be non-zero. Parameter 1 must be greater than or equal to parameter 2. Parameter 5 must either be zero (unused) or greater than or equal to parameter 2. When trafficDescType is 8, parameter 1 represents the PCR for CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for CLP equal to 0 traffic with cell tagging; parameter 3 represents the MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT; and parameter 5 represents the requested shaping rate. A non-zero value in parameter 5 overrides any value in parameter 1. This result is used as the PCR. Parameters 1, 2, and 3 must be non-zero. Parameter 1 must be greater than or equal to parameter 2. Parameter 5 must either be zero (unused) or greater than or equal to parameter 2. Whenever it is valid for PCR to be specified, parameter 5 may also be used to specify a requested shaping rate. A non-zero value in parameter 5 overrides the value in parameter 1 and is used as the peak cell rate in calculations of CAC and shaping rate. For trafficDescType 3 the traffic is shaped at the next rate less than the PCR. For trafficDescType 6, 7, and 8, the traffic is shaped at the highest available rate which is between PCR and SCR. However, if there is no available shaping rate between PCR and SCR, traffic is shaped at the next rate above the PCR.

An entry in the atmIfUniSigProvTable.

This attribute specifies the signalling channel number.

This attribute specifies the address conversion on the outgoing signalling PDUs. The options are none, nativeE164, or nsap. The none option is the default and if this option is chosen then nothing is done to the address information element (IE) in the outgoing signalling message. If nativeE164 option is chosen, then only NSAP encapsulated E.164 addresses with zeros in the ESI are converted to native E.164 format in the outgoing signalling message. If the NSAP address is not encapsulated E.164 or the ESI field is not zeros and the nativeE164 option is chosen, then the call is cleared. If the nsap option is chosen, then native E.164 addresses are converted to NSAP E.164 with zeros in the ESI field; otherwise the address is in NSAP format and is not changed. Enumeration: 'none': 0, 'nativeE164': 1, 'nsap': 2.

When trafficDescType is 3, parameter 1 represents the PCR for CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and parameter 5 represents the requested shaping rate. A non-zero value in parameter 5 overrides any value in parameter 1. This result is used as the PCR. Parameter 1 must be non-zero. Parameters 2 and 3 must be zero. When trafficDescType is 6, parameter 1 represents the PCR for CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and parameter 5 represents the requested shaping rate. A non-zero value in parameter 5 overrides any value in parameter 1. This result is used as the PCR. Parameters 1, 2, and 3 must be non-zero. Parameter 1 must be greater than or equal to parameter 2. Parameter 5 must either be zero (unused) or greater than or equal to parameter 2. When trafficDescType is 7, parameter 1 represents the PCR for CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for CLP equal to 0 with cell discard; parameter 3 represents the MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT; and parameter 5 represents the requested shaping rate. A non-zero value in parameter 5 overrides any value in parameter 1. This result is used as the PCR. Parameters 1, 2, and 3 must be non-zero. Parameter 1 must be greater than or equal to parameter 2. Parameter 5 must either be zero (unused) or greater than or equal to parameter 2. When trafficDescType is 8, parameter 1 represents the PCR for CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for CLP equal to 0 traffic with cell tagging; parameter 3 represents the MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT; and parameter 5 represents the requested shaping rate. A non-zero value in parameter 5 overrides any value in parameter 1. This result is used as the PCR. Parameters 1, 2, and 3 must be non-zero. Parameter 1 must be greater than or equal to parameter 2. Parameter 5 must either be zero (unused) or greater than or equal to parameter 2. Whenever it is valid for PCR to be specified, parameter 5 may also be used to specify a requested shaping rate. A non-zero value in parameter 5 overrides the value in parameter 1 and is used as the peak cell rate in calculations of CAC and shaping rate. For trafficDescType 3 the traffic is shaped at the next rate less than the PCR. For trafficDescType 6, 7, and 8, the traffic is shaped at the highest available rate which is between PCR and SCR. However, if there is no available shaping rate between PCR and SCR, traffic is shaped at the next rate above the PCR.

This attribute group contains the provisionable attributes for the Signalling component.

An entry in the atmIfVptUniSigProvTable.

This attribute specifies the signalling channel number.

This attribute specifies the address conversion on the outgoing signalling PDUs. The options are none, nativeE164, or nsap. The none option is the default and if this option is chosen then nothing is done to the address information element (IE) in the outgoing signalling message. If nativeE164 option is chosen, then only NSAP encapsulated E.164 addresses with zeros in the ESI are converted to native E.164 format in the outgoing signalling message. If the NSAP address is not encapsulated E.164 or the ESI field is not zeros and the nativeE164 option is chosen, then the call is cleared. If the nsap option is chosen, then native E.164 addresses are converted to NSAP E.164 with zeros in the ESI field; otherwise the address is in NSAP format and is not changed. Enumeration: 'none': 0, 'nativeE164': 1, 'nsap': 2.
