ATM T3 and E3 Network Modules
ATM T3 and E3 network modules provide T3 and E3 ATM connectivity for high-bandwidth data
applications. There are three versions of these network modules: the ATM T3 Network Module, the ATM
E3 Network Module, and the ATM T3/E3 Network Module. See
Figure
Adaptive Layer 5 (RFC 1483), classic IP over ATM encapsulation (RFC 1577), Point-to-Point Protocol
(PPP) over ATM, and LAN Emulation (LANE). Up to 1024 virtual circuits (VCs) are supported on the
ATM T3/E3 network modules.
