Combined with
Covaro's Etherjack(R) demarcation technology these devices offer service
providers and enterprise customers alike the ability to remotely administer
and maintain their Ethernet services with the industry's richest set of
Ethernet OAM capabilities .
Featuring Etherjack technology, the CC-5xx and CC-8xx families provide an
Ethernet demarcation point between provider and customer networks.
Atmel and port will be exhibiting this technology at the Embedded World
Show in Nuremberg, Germany, February 22-24, 2005.

The CC-8xx family of devices provides Ethernet
demarcation and Ethernet media conversion at Gigabit speeds similar to
Covaro's successful CC-4xx family. The CC-
8xx family utilizes small form factor pluggable (SFP) optical devices and can
take advantage of dark fiber to deliver intelligent Ethernet services over a
wide range of optical applications . These functions contribute to improved efficiency,
increased effectiveness and reduced costs. These device profiles
guarantee a defined device behavior and provide interchangeability of CANopen
devices .port.

"Ethernet's inherently lower capital
costs increases the focus on reducing operations costs. It may be used to implement network master , slave or mixed
applications, using more than one CAN channel for controlling the CANopen
network . The AT91SAM7A1 has a single CAN interface, three
UARTs and multiple timers including support for PWM and input capture, making
it ideal for CANopen peripheral devices. Focused on consumer,
