ATMF25 port

This port, optional available on the single Ethernet port
STHome
,
does not terminate ATM connections, it just switches ATM cells
between the DSL and ATMF25.6 port.
It is the ATMF25.6 PCNIC of the PC that actually initiates, or
terminates ATM VCs.
It is important to check in advance which protocols are supported
by the ATMF25.6 PCNIC driver. At least RFC1483 and RFC2364
should be fully implemented.
This port terminates a number of ATM connections and extracts
frames from arriving cells and encapsulates frames in departing
cells.
Only frames recognized/supported by the
STHome
on
a particular ATM connection are extracted, or encapsulated.
Currently the supported encapsulations are:
For
Transparently Bridged
connections:
RFC 1483, Ethernet V2.0/IEEE 802.3 bridged PDUs for both
the LLC/SNAP method and VCMUX method
For
Bridged PPPoE
connections:
RFC 1483, Ethernet V2.0/IEEE 802.3 bridged PDUs for both
the LLC/SNAP method and VCMUX method
For
PPPoAtoPPTP Relaying
connections:
RFC 2364, PPP PDUs for both the LLC/NLPID method and
VCMUX method.
