Combining ZyXEL’s MEF certi ed Carrier

Ethernet switches, leading VDSL2 DSLAMs

and Extreme Networks’ BlackDiamond

12000 series, wilhelm.tel successfully

supplies residence customers in greater

Hamburg with Internet, telephony, and

cable TV service.

High Quality Solution

“wilhelm.tel is delivering a more scalable,

resilient network with advanced Ethernet

and  bre technology. The combination

of Extreme Networks’ and ZyXEL’s Active

Ethernet ETTx, VDSL2 FTTx solution plays

an important role in providing higher

quality communications, increased

bandwidth and subscriber scale,” said

Heiko Liebscher, CTO for wilhelm.tel. “The

economies are superior with Ethernet

and  bre, allowing one network to serve

many needs and preparing us for the

future.”

Extreme Networks’ Carrier Ethernet

switches are designed to provide service

providers with  exible and cost-e ective

solutions to meet their high availability

requirements for converged services. “We

are pleased to have ZyXEL join our Go

Purple Partner Program and add to the

best-of-breed vendors which promote

interoperable and scalable networks,” said

Future Prospects

Successfull Partnership: The new alliance

between ZyXEL Communications and

Extreme Networks will complete the end-

to-end Carrier Ethernet product portfolio

for service providers. With architectural

 exibility and intelligent service delivery

mechanisms, service provider customers

will be able to build a scalable and reliable

service-driven metro network for maximum

return on investment.

Market Challenge

Multi-service is a trend and de nitely

the key for service providers to attract or

sustain subscribers. Foreseeing constant

bandwidth demand driven by multi-service,

data, voice and video, service providers

need to have the ambition to build up a

reliable and secure  bre network to the

home which provides new-generation IP

services for their subscribers.

Background: In December 2009, Extreme

Networks, Inc. and ZyXEL Communications,

a leading broadband access solutions

provider, announced that ZyXEL‘s MEF

certi ed Carrier Ethernet switches and

Extreme Networks‘ Carrier Ethernet

solutions, including the BlackDiamond

20800 Carrier Ethernet transport switch,

have been jointly tested for interoperability

to ensure reliable network performance.

They are thus able to o er a comprehensive

integrated FTTx solution for service

providers.

Architectural  exibility and intelligent

service delivery were tested for

interoperability as part of Extreme Networks‘

Go Purple Partner Program. The companies

also evaluated fast failover over resilient

rings, the implementation of Quality

of Service (QoS), and network security.

These jointly tested solutions help service

providers to build a scalable and reliable

service-driven Carrier Ethernet network.

The city carrier wilhelm.tel is a cable operator
