The Speed Touch Home Transparent Bridging packet service offers
complete protocol transparency and has inherent configuration
simplicity. Yet it provides excellent forwarding performance.
In contrast to Bridging, PPPoA to PPTP Relaying supports a session
concept. It offers identification, authentication and encryption.
Similar to Bridging, PPPoA to PPTP Relaying is multiprotocol and
offers complete Transmission Control Protocol (TCP)/Internet
Protocol (IP) transparency.
The STHome ADSL modem relies on ATM technology for its wide
area communications.
On top of ADSL, both Bridging and PPPoA to PPTP Relaying use ATM
virtual channels. The Virtual Path Identifier (VPI)/Virtual Channel
Identifier (VCI) are 2 numbers that together uniquely identify a Virtual
Channel (VC).
The remote organization, i.e. ADSL provider, ISP , or corporate has to
provide following information about the ATM layer:
The type of packet service that is enabled, i.e. Bridging, or
"
PPPoA to PPTP Relaying.
The ATM/AAL5 encapsulation method, i.e. LLC/SNAP , or VC
"
MUX, per packet service
The VPI/VCI values per packet service.
"
Additionally, the remote organization may provide you with:
A User Account, i.e. user name and password.
"
Additional User Accounts might be required for access to specific
secured servers.
If STHome default settings differ with the provided information,
change the settings accordingly.
