Background Information

Specifically, this document explains the VT1.5 switching capabilities of individual line cards; the architecture
of the Cisco ONS 15454 Cross Connect (XC) cards and Cross Connect VT (XC−VT and XC10G) cards
responsible for switching VT1.5 circuits; and how these cards operate with Bidirectional Line Switched Ring
(BLSR), UPSR, Linear 1 + 1, and standard STS−1 connections. Sample configurations show how to achieve
the maximum switching capabilities and how to exhaust the available STS−1 ports on the (VTX is used
frequently and in many of the diagrams...) matrix before these maximums are reached.

Line Card Capacities for VT1.5 Traffic

The table below shows which Cisco ONS 15454 line cards the XC−VTand XC10G can use for switching
VT1.5 traffic and the maximum number of VT1.5 circuits that can be configured on each card.
