Overview

You can provision ATM virtual paths (VPs) and virtual channels (VCs) on the NE for use with internal and external ATM connections.

ATM can be provisioned on the following line cards:

MSDSL-2W
T1-2-V35
OC3c-UNI

Provisioning Lines

To provision a line for ATM, complete the following steps starting in node view:

Step 1 Double-click the line to be provisioned. EMS launches the line provisioning window. (See Figure 13-1.)

Figure 13-1: Provisioning Line for ATM

Step 2 Set the following fields for your ATM application:

Line Frame Type—Select HDLU-C (high-speed digital line unit, central node) or HDLU-R (high-speed digital line unit, remote node). Endpoints of an ATM virtual channel (VC) should be set to HDLU-R.
Bundle Size—Set the maximum number of DS0 channels provisioned to carry data traffic. This must be greater than 0 to enable ATM provisioning.

Step 3 Click Apply to provision the line.

Step 4 Repeat this procedure to provision other lines on the line card.

Assigning Virtual Paths and Virtual Channels

Each line must be provisioned with at least one virtual path (VP) and one virtual channel (VC) before ATM traffic can be accommodated.

To assign VPs and VCs, complete the following steps starting from node view:

Step 1 Right-click the line to be provisioned, and select ATM Provisioning from the popup menu. EMS launches the ATM provisioning window. (See Figure 13-2.)

Figure 13-2: ATM Provisioning Window

Step 2 The following ATM parameters should be set according to your ATM application:

ATM Interface Type
Max Active VPI Bits and Max Active VCI Bits
Cell Scrambling

Step 3 Click the VP/VC Assignment tab. EMS launches ATM Provisioning Window view that is used to assign VP/VCs. (See Figure 13-3.)

Figure 13-3: VP/VC Assignment Window

Step 4 Set the following ATM parameters:

VPI From/To—Enter the range of VPIs to be assigned to this line.
VCI From/To—Enter the range of VCIs to be assigned to this line.
Segment VP Endpoint
Segment VC Endpoint
VC AAL Type—Select AAL5 to provision the new VCs for ATM Adaptation Layer 5 (AAL5), or select None to provision VCs without using an adaption layer.

Step 5 Click Create VP to provision the VPs. The newly-created VPs appear in the VP/VC List at the right side of the window.

Step 6 Click Create VC to provision the VCs. The newly-created VPs and VCs appear in the VP/VC List.

Deleting VPs and VCs

To delete VPs and VCs provisioned on a line, complete the following steps starting in node view:

Step 1 Right-click the line icon, and select ATM Provisioning from the pop-up menu. EMS launches the ATM Provisioning Window view that is used to assign VP/VCs. (See Figure 13-3, above.)

Step 2 Click the VP/VC Modify and Delete tab. EMS displays a list of VPs and VCs provisioned on the line. (See Figure 13-4.)

Figure 13-4: VP/VC Assignment Window

Step 3 In the VP/VC List at the right side of the window, highlight the VPs and VCs to be deleted.

Step 4 Click Delete. EMS removes the highlighted VPs and VCs from the list.

Creating ATM Cross Connects

After a line had been provisioned with a VP and VC, you can create an ATM cross connect to another line in the NE chassis.

To create an ATM cross connect, complete the following steps starting in node view:

Step 1 Right-click the line to start the cross connect, and select ATM Cross Connect from the popup menu. EMS displays a list of all available VP/VCs on the line. (See Figure 13-5.)

Figure 13-5: ATM Cross Connect VP/VC Display

Step 2 Highlight the VP/VC to be cross connected. EMS displays the VP/VC number in the Selected VPI and Selected VCI windows at the top of the list. (See Figure 13-6.)

Step 3 Click the Selected VCI text box, and drag the cursor to the desired facility.

Step 4 After the visual cross connect is drawn, EMS launches the ATM Cross Connect Provisioning window. (See Figure 13-7.) The VP/VC list on the left shows all VP/VCs for the source (originating) line, and the VP/VC list on the right shows VP/VCs for the destination line.

Step 5 Highlight the source VP/VC to be cross connected in the left VP/VC List.

Step 6 Highlight the destination VP/VC in the right VP/VC List. You must select one VP/VC on each line.

Step 7 Click Create to provision the ATM cross connection. EMS confirms the cross connect creation by displaying the letter "y" in the "CC" column, next to the connected VP/VCs. (See Figure 13-8.)

Delete ATM Cross Connects

To delete ATM cross connects, perform the following steps starting in node view:

Step 1 Right-click a line, and select ATM Cross Connect from the popup menu. EMS launches the ATM cross connect provisioning window. (See Figure 13-9.) The VP/VC List displays all VP/VCs configured on the line.

Figure 13-9: ATM Cross Connect Provisioning Window

Step 2 In the VP/VC List, highlight the VP/VCs to be deleted.

Step 3 Click Delete. EMS removes the deleted cross connects from the VP/VC list display.

Close ATM Cross Connect Display

To close the ATM cross connect display, right-click on the VPI/VCI list in node view, and select End ATM Cross Connect Display from the popup menu. EMS closes the cross connect display.

Displaying ATM Lists

To display ATM lists showing VP/VC assignments and ATM cross connects, perform the following steps starting in node view:

Step 1 Select Objects > ATM Lists from the node view menu bar. EMS launches the ATM VPI/VCI list. (See Figure 13-10.)

Figure 13-10: ATM VPI/VCI List

Step 2 Select ATM Cross Connect List from the function bar. EMS launches the ATM cross connect list. (See Figure 13-11.)

Step 3 Click Exit to return to node view.
