9.3.1 Multicard EtherSwitch

Multicard EtherSwitch provisions two or more Ethernet cards to act as a single layer 2 switch. It supports
one STS-3c circuit or three 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-3c worth of
bandwidth.

Single-card EtherSwitch allows each Ethernet card to remain a single switching entity within the
ONS 15327 shelf. This option allows a full STS-12c worth of bandwidth between two Ethernet circuit
points.
