The CellPipe 20A is a high-speed Asymmetrical Digital Subscriber Line (ADSL) device that supports bridging over ATM. It supports RFC1483 Multiprotocol over AAL5. You can use the CellPipe 20A to create a dedicated, physical connection to Digital Subscriber Line (DSL) equipment at the telephone company. You first attach your computer or Ethernet hub to the CellPipe 20A. Then, you connect the unit to a standard telephone line. The other end of the line connects to DSL equipment at the telephone company. Your DSL circuit is dedicated to your CellPipe unit.

With DSL, you have the capacity to transfer data at very high rates. The actual rate can vary according to the type of CellPipe you use, the distance between the CellPipe and the DSL equipment, and the line quality of the connection. You can use DSL technology for Internet access, telecommuting, remote office connectivity, multimedia, and videoconferencing.

CellPipe 20A features
The CellPipe 20A includes the following features:
• ATM over ADSL through a single copper twisted-pair telephone line
• 10/100 MB Ethernet (Auto-detect)
• High-speed bridging
• DMT-based standards
• Support for ATM AAL5 (ATM Adaptation Layer Type 5)
• Support for VC-based multiplexing and LLC encapsulation of RFC1483
• Autonegotiating rate adaptation
• Ease of use
• Easy configuration

CellPipe 20A management
The CellPipe 20A is managed through a command-line interface. You set up a serial connection and use VT100 emulation software to display configuration information on your computer monitor and use the computer to enter any changes. You can use the command-line interface to change the VPI and VCI value, and the MUX type. The default VPI and VCI values are 8 and 35, respectively. The default MUX type is LLC encapsulation. You can also use the command-line interface to change the console baud rate at which you connect to the CellPipe 20A unit. For a discussion of the command-line interface, see Chapter 3, “Configuration.”
