• Disable
Disables the ATM mode.
• 1483 Bridging
Bridging: Bridging is a standardized layer 2 technology. It is typically
used in corporate networks to extend the physical reach of a single
LAN segment and increase the number of stations on a LAN without
compromising performance. Bridged data is encapsulated using the
RFC1483 protocol to enable data transport.
