13.1.2 ATM and the STPro

The following figure provides an overview of the endtoend

architecture of the ATM connectivity; from your STPro to remote

access devices.

Corporate Access Point

Internet

ISP Access Point

ATM Crossconnect

DSL Line

Multiple ATM

virtual channels

Ethernet

ATMF25.6

This channel is not crossconnected

Symbolizes a cross connection.

Hence no endtoend connectivity!

Remote LAN

Practically speaking, a number of VCs to one, or multiple remote

destination(s) can start from/are terminated at the STPro.

By default, a number of channels are terminated in the STPro for

Ethernet; others are crossconnected to the ATMF25.6 port (if

equipped).

Endtoend ATM connectivity is the responsibility of local

operators. There might be regional differences in the type and

number of VCs that are crossconnected.

If problems are encountered, check with your local operator for

more information.
