Virtual Channel Support

The number of virtual channels (VCs) that the router supports on each port varies
depending on the E Series router and module you are using. For information about
the maximum number of ATM VCs supported per chassis, per module, and per port,
see JUNOSe Release Notes, Appendix A, System Maximums.

ATM NBMA

The software supports nonbroadcast multiaccess (NBMA) networks, which
interconnect more than two routers and have no broadcast capabilities.
NOTE: The E120 and E320 routers do not support ATM NBMA in the current release.
An ATM NBMA network can be thought of as an interface stack with a single IP
interface at the top, eventually fanning out to multiple independent PVCs. See Figure
2 on page 14.
