How to Configure ATM Services in an end-to-end Mode?

Hello, friend.

You must be an NM user with NE operator authority or higher.

Tools, Equipment, and Materials

U2000

Procedure

1. Choose Service > PWE3 Service > Create PWE3 Service from the Main Menu.

2. Set the basic attributes for ATM services.

Set the parameters as follows:

• Service template: If no service template has been specified, it is recommended that you set this parameter to DEFAULT_PWE3_ATM_PTN/ATN.

• Service Type: ATM

• Service ID and Service Name: Unless otherwise specified, these two parameters take their default values. The U2000 automatically generates the parameter values according to the service naming rules. An appropriate Service Name improves service maintainability in the case of centralized management.

• Protection Type: Protection-Free

1. Configure the NEs and service ports on the NEs that are involved in the ATM service.

a.  Double-click the source NE in the Physical Topology tab page.

b.  Select the service port on the NE.

c.  Click OK.

d.  Repeat 3.a and 3.c to configure the service port on the sink NE.

e.  Optional: In the Physical Topology tab page, right-click the S-PE and choose Set As Switching Node > Working from the shortcut menu.

NOTE:

To create an unterminated PWE3 service, of which the PE at one end is unreachable on the U2000, right-click the service in the physical topology and choose related options from the shortcut menu to create the service source or sink (a virtual node).

      Optional: Set the basic attributes of the PW.

Set Forward Tunnel, Reverse Tunnel, PW ID, Forward Label, and Reverse Label.

      Optional: Configure the QoS information of the PW.

 .  Click Detail.

a.  In the PW QoS tab page, configure the QoS information of the PW.

Unless otherwise specified, it is recommended that all parameters in the tab take their default values.

      Optional: Set the advanced attributes of the PW.

 .  Click Detail.

a.  In the Advanced PW Attribute tab page, set the advanced attributes of the PW.

Unless otherwise specified, it is recommended that all parameters in the tab take their default values.

      Configure ATM connections.

 .  Click ATM Link.
The Configure Link dialog box is displayed.

a.  Click Add Link.

b.  Set the ATM connection attributes according to network planning information.

NOTE:

If multiple ATM connections have been planned, configure all the planned ATM connections.

c.  Click OK.

      Select Deploy and Enable at the lower left corner.

o    After Deploy is selected, the tunnel configuration data is saved on the U2000 side and deployed to the NE side. If you do not select Deploy, the service configuration data is saved on the U2000 side but is not deployed to the NE side.

o    For the OptiX RTN 950, generally only ATM PWE3 services are used. Therefore, always select Enabled.

      Click OK.

      In the Operation Result dialog box that is displayed, select Browse Trail.

The new ATM service is displayed in the PWE3 service list.

Thanks.
