Cisco ONS 15454 Product Overview

Ethernet

Single-Card and Multicard EtherSwitch

The ONS 15454 supports single-card and multicard EtherSwitch.

When you provision single-card EtherSwitch, each Ethernet card is a single switching

entity within the ONS 15454. This option allows STS-12c of bandwidth between two

Ethernet circuit points. Single-card EtherSwitch supports one STS-12c, two STS-6c,

four STS-3c, or twelve STS-1 circuits.

Figure 19 Single-card EtherSwitch

When you provision multicard EtherSwitch, two or more Ethernet cards act as a single

layer 2 switch. Multicard EtherSwitch supports one STS-6c shared packet ring, two

STS-3c shared packet rings, or six STS-1 shared packet rings. The bandwidth of the

single switch formed by the Ethernet cards matches the bandwidth of the provisioned

Ethernet circuit up to STS-6c worth of bandwidth.
