The VSC7331VH is an essential component

enabling cost-effective, new-generation,

metropolitan network markets

Business Continuance Networks

Terrestrial Broadcast Networks

Metro Virtual Private Networks

When used with the VSC9118, the VSC7331 creates a

powerful solution for a Universal Line Card that leverages

advances in SONET/SDH networks for Metro Area Networks.

The VSC7331 makes optimal use of the Virtual Concatenation

and LCAS capabilities provided in the VSC9118 to facilitate

optimum bandwidth utilization.

Because each port can be independently configured for any

of the supported protocols in the Universal Line Card (10/100

/1000 Mb/s Ethernet, Fibre Channel, FICON, ESCON or DVB-

ASI), Carriers and Services Providers do not have to stock

multiple versions of this line card. Such flexibility is central

to offering cost-effective solutions for Carriers and Service

Providers ensuring competitive deployment of technical and

financial resources.

The Vitesse Mapper and MAC components come together

seamlessly to offer an optimal solution for cost-effective

development of applications addressing high-density,

flexible, client interfaces through OC-192 SONET/SDH

connectivity with STS-1 granularity. The intelligence and

flexibility of the VSC7331VH make it a central building block

for metro data services equipment and networks.

The Vitesse VSC7331 is a 10-Gigabit, Multi-Protocol, Multi-

Rate Metro Data Services Media Access Controller (MAC).

Each port can be independently configured to support any of

the supported data streams, including, Ethernet (10/100/1000

Mb/s), Fibre channel (1-Gigabit), FICON, ESCON or DVB-ASI.

Alternatively, the VSC7331 can be configured for a single 10-

Gigabit Ethernet port.

Line interfaces include Ethernet SERDES, TBI, RGMII, MII or

XAUI. The Data Interface is an OIF Standard SPI-4.2 10-

Gigabit, multi-channel interface. Key features include Metro

Area Flow Control and Advanced Port Aggregation.
