ATM and Interfaces

ATM traffic handling
ATM traffic arriving at the STPro is switched to either the Ethernet
port(s), or the (optional) ATMF 25.6 port depending on
the VPI/VCI values in the individual cells.
Inside ATM VCs any protocol can be transported. However, at
both endpoints - that is where the ATM channels are terminated
-, the same protocol must be supported. If not, there will be no
end to end connectivity.
ATMF 25 port
This port, optional available on the single Ethernet port STPro,
does not terminate ATM connections, it just switches ATM cells
between the DSL and ATMF 25.6 port.
It is the ATMF 25.6 PC NIC of the PC that actually initiates, or
terminates ATM VCs.
It is important to check in advance which protocols are supported
by the ATMF 25.6 PC NIC driver. At least RFC1483 and RFC2364
should be fully implemented.
See section 11.2 for more information.
