ATM
ATM cells in a Virtual Channel (VC). The Megabit Modem 400F has 32 VCs in the VP, which provides the 32 sessions.
Mapping an ATM Session
Your service provider will give you a VCI and VPI address for each session. The VCI address for each session (each session is a VC) can be a number from 32 up to a maximum of 255, with the first 32 numbers (0 through 31) reserved. The VCI value for each VC must be unique for each of the 32 sessions. The addresses range from 0 to 253 for VCI and 0 to 15 for VPI.
