ATM Policy

For ATM services, configure the ATM policy to perform the QoS control over the traffic.

Navigation Path

In the NE Explorer, click the NE and choose Configuration > QoS Management > Policy Management. Then, click the ATM Policy tab.

Buttons

Button	Description
New	Click New to create a ATM policy.
Delete	Select the desired ATM policy and click Delete. NOTE: The policy to be deleted is not used.
Apply	Configurations take effect only by clicking Apply after ATM policy parameters are modified. NOTE: The policy to be deleted is not used.
Query	Select the ATM policy for the query. Click the Applied Object tab and click Query. Information on the service that uses this policy is displayed. NOTE: The ATM policy is already applied to a service.
Copy	Copy the existing ATM policy as a new policy.

Parameters

**Table 1** Descriptions of the parameters for ATM Policy
Field	Value	Description
Policy ID	Example: 5	Sets and displays the ID of the policy.
Automatically Assign	Checked and Unchecked	Selects whether the ID is allocated automatically.
Policy Name	64 bytes	Sets and displays the name of the policy. NOTE: You can select a policy name from the drop-down list or manually enter the policy name. The ATM service policy has five levels.
Service Type	UBR, CBR, RT-VBR, NRT-VBR, UBR+	Sets the service type. UBR indicates the ATM service of an unspecified bit rate. With support for the non-real-time application, the UBR service has no guaranteed service quality and thus is applicable to transmitting IP data packets. CBR indicates the ATM service of a constant bit rate. CBR is used for the connection that requires a static bandwidth. The CBR service is applicable to the real-time services that have high requirements of delay change, such as the audio, video and circuit emulation services. RT-VBR indicates the ATM service of the real-time variable bit rate. As a real-time application, the RT-VBR requires strictly limited delay. The RT-VBR service is applicable to audio and video services. NRT-VBR indicates the ATM service of the non-real-time variable bit rate. As a non-real-time application for burst traffic, the NRT-VBR service ensures a low cell loss ratio without limiting the delay. The UBR+ service supports the setting of the MCR parameter. There are UBR+ services on many NodeBs. The UBR+ services are configured with the MCR. When the service rate does not exceed the configured MCR, the normal service transmission is ensured. The features of the UBR+ service other than the MCR are the same as the features of the UBR service.
Traffic Type	NoTrafficDescriptor, NoClpNoScr, NoClpTaggingNoScr, NoClpNoScrCdvt, ClpNoTaggingNoScr, ClpTaggingNoScr, ClpTransparenNoScr, ClpTransparentScr, NoClpScrCdvt, ClpNoTaggingScrCdvt, NoClpScr, ClpNoTaggingScr, ClpTaggingScr, AtmNoTrafficDescriptorMcr, AtmNoClpMcr, atmNoClpMcrCdvt	Sets the traffic service.
Clp01Pcr(cell/s)	90 to 149078	Sets the traffic descriptor, that is, Clp01Pcr. Clp01Pcr indicates the maximum transmission rate of cells.
Clp01Scr(cell/s)	90 to 149078	Sets the traffic descriptor, that is, Clp01Scr. Clp01Scr indicates the average transmission rate of cells during a long time.
Clp0Pcr(cell/s)	90 to 149078	Sets the traffic descriptor, that is, Clp0Pcr.
Clp0Scr(cell/s)	90 to 149078	Sets the traffic descriptor, that is, Clp0Scr.
Clp01Mcr (cell/s)	90 to 149078	Sets the traffic descriptor, that is, Clp01Mcr.
Max. Cell Burst Size(cell)	2 to 200000	Sets the maximum size of burst cells. This parameter indicates the maximum length that the ATM cells can reach.
Cell Delay Variation Tolerance(0.1us)	7 to 13300000	Sets the cell delay variation tolerance. This parameter indicates the maximum delay of the ATM cells.
Discard Traffic Frame	Disable, Enable	Enables or disables the flag for discarding the traffic frame.
UPC/NPC	Disabled, Enabled	Enables or disables UPC/NPC. UPC indicates the usage parameter control and NPC indicates the network parameter control. After UPC/NPC is enabled, the cells with flags are discarded in the case of network congestion.
Service ID	Example: 5	Displays the ID of the configured ATM service.
Service Name	Example: ATM service	Displays the name of the configured ATM service.
Direction	Egress, Ingress	Sets the service direction.
Link ID	Example: 123	Display the ID of the connection.
Duplicated Policy Name	Example: QoS-test	Selects the name of the duplicated policy.
New Policy Name	Example: Test	Sets the name of the new policy generated by duplicating another one.
