Cape.Computing: Help With DSL Connections - ADSL Hardware Compatibility

For an ADSL modem/router to work over Cape.Com's DSL Network, the modems chipset must support Bridged Ethernet for RFC 1483/ATM with a VPI/VCI pair as follows:

Many ADSL modems auto-negotiate the VPI/VCI, while some must have the VPI/VCI set manually, either via a telnet connection or terminal/console access.

For example, the Efficient Speedstream 5260 Ethernet ADSL modem must have the VPI/VCI set manually, while Westell's Wirespeed "White" auto-negotiates the settings. A Cisco 827 ADSL router must be configured manually to establish connectivity over Cape.Com's ADSL network.

VPI/VCI (Virtual Path Identifier/Virtual Channel Identifier) - The VPI (Virtual Path Identifier, an 8-bit field in an ATM header), combined with the VCI (Virtual Channel Identifier, a 16-bit field in an ATM header), is used to identify the next destination of a cell as it passes through a series of ATM switches. The modem must be compatible with this series of events to operate properly.

Compatible Products:
Note: compatibility states that the equipment has an ADSL chipset. Most standard routers can be connected to ADSL modems, though some routers, such as the Cisco 827 Router, act as both the modem and the router combined in one piece of hardware. The Compatibility list is taken from information on the manufacturers website. Cape.Com's Technical Support Representatives directly support the following ADSL Hardware:

Westell Wirespeed "White" Modem (Model B90-36R516-01)
Efficient Speedstream 5260 Ethernet Modem
Efficient Speedstream 3060 PCI Modem
