What is the CellPipe 20A-USB?
The CellPipe 20A-USB is an ADSL modem connected via the USB port on your computer.
ADSL modems employ ATM (Asynchronous Transfer Mode) framing. ATM is a protocol that
divides packets into small fixed-sized cells for rapid transmission over high-speed networks.
The ATM protocol allows various types of traffic (e.g., data, voice, and video) to be securely
and efficiently carried over the same network. ATM is being widely deployed by
telecommunications carriers in their backbone networks. Two type of ATM connections are
possible, PVC (Permanent Virtual Circuit) and SVC (Switched Virtual Circuit).
