VSC9191

100 Gbps (40 x 40) SONET/SDH TSI Switch with Dual Rate I/O

A Vitesse TSI Switch Family Member

The VSC9191 is a 40 x 40 Time Slot Interchange (TSI)

switch supporting multirate OC-48/OC-12 data on every

input and output. All inputs and outputs are differential

serial signals running at 2.488 Gbps or 622 Mbps for

TDM signals, and 2.125 Gbps or 2.488 Gbps for signals

routed transparently.

The device contains a fully non-blocking STS-1 switching

matrix surrounded by serial backplane interfaces that

incorporate fully integrated clock recovery and synthesis,

input equalization, output pre-emphasis, SONET/SDH

compliant scrambling, framing, deskew, and alarms.

Ports to drop and insert overhead bytes are included. A

multimode CPU interface is used for device configuration

and status monitoring.

Use Standalone or as a Building Block

The VSC9191 is designed for use in a central switch unit

in smaller SONET/SDH systems. Alternatively, the

VSC9191 can be used as a building block for larger

680 Gbps to 1.36 Tbps systems when used in

conjunction with additional Vitesse TSIs such as the

VSC9195 or VSC9295.

The Vitesse TSI Family of Switches

Vitesse offers a complete line of SONET/SDH TSI

products for building systems of any size. Vitesse TSI

products are designed for maximum flexibility in building

and managing SONET and packet systems.
