This document explains how to create virtual tributary (VT) for both unidirectional path switched ring
(UPSR) and bidirectional line switched ring (BLSR) topologies that run Cisco ONS 15454 Release 3.10
software (Release 3.10−001K−17.01).

Refer to Understanding the 15454 XC and XC−VT Switching Matrix for an explanation and examples of the
VT matrix capabilities.

Note: The Cisco ONS 15454 Troubleshooting and Maintenance Guide contains detailed specifications of the
cross connect (XC), cross connect virtual tributary (XCVT), and XC10G cards.

You can provision circuits before cards are installed. The ONS 15454 allows you to provision slots and
circuits before you install the traffic cards. Right−click it and choose a card from the shortcut menu in order to
provision an empty slot. But, circuits do not carry traffic until you install the cards and put their ports into
service. Refer to the instructions on how to install optical, electrical, and Ethernet cards and enabling ports in
the Card Provisioning document for procedures.

After cards are installed, the ports are out of service. You must place the ports in service before the circuits
carry traffic. Once cards are installed, and their ports are in service, the circuits carry traffic as soon as the
signal is received.
