Unprotected, bi-directional cross-connect: concatenated

group (VC4-7V) and STM-N port

Procedure

This procedure is performed on an OC-48 port. In case a OC-192 port is used, the same.

From EML-USM, select "Configuration" -> "Data Port Configuration."

In "Data Port Configuration" window, select the port number.

In "Selected Item" field, select the signal type (VC4XV) and the number of virtual

concatenated VC4s (7 in the current example). It has to be taken into account that up to 7

VC4s may be concatenated to have a GbE stream, and up to 64 VC4s may be concatenated

to have a 10 GbE stream. Then click on the "Create/Change" button.

In "Data Port Configuration" window, click on "LCAS Cfg." Then click on "Enable" and

"Apply."

To activate TPs, click on "Ctrl Path Act." In the "Control Path Activation" window, select

the number of "TPs to be active" (7), and click on "Apply."

All TPs are now active and it will be possible to create cross-connections.

Now we have to cross-connect the created VC4-7V (on PIMMS) to the STM-N port of the

SONET board, by cross-connecting each AU4 of the VC4-7V to a different AU4 of the

chosen STM-N port.

From EML-USM, select "Cross-Connection Management" from the "Configuration"

menu.

The "Cross-Connection Management" window is displayed.

Click on "Create." A "Main Cross-Connection" window is displayed.

Select the type: "Bidirectional" - "Not Protected."
