3.8.2 LLC–based Multiplexing
In this case one VC carries multiple protocols with protocol identifying information being contained in each
packet header. Despite the extra bandwidth and processing overhead, this method may be advantageous if it
is not practical to have a separate VC for each carried protocol, for example, if charging heavily depends on
the number of simultaneous VCs.
3.9 Encapsulation
Be sure to use the encapsulation method required by your ISP. The Prestige supports the following
methods.
3.9.1 PPPoA
Please refer to RFC 2364 for more information on PPP over ATM Adaptation Layer 5 (AAL5). Refer to
RFC 1661 for more information on PPP.
3.9.2 RFC 1483
RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5 (AAL5).
The first method allows multiplexing of multiple protocols over a single ATM virtual circuit (LLC-based
multiplexing) and the second method assumes that each protocol is carried over a separate ATM virtual
circuit (VC-based multiplexing). Please refer to the RFC for more detailed information.
3.10 IP Address Assignment
A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a different
one each time.
3.11 Internet Access Configuration
Menu 4 allows you to enter your Internet Access information in one screen. Menu 4 is actually a simplified
setup for one of the remote nodes that you can access in menu 11. Before you configure your Prestige for
Internet access, you need to collect your Internet account information from your ISP and telephone
company.
Use the following table to record your Internet Account Information. Note that if you are using PPPoA
encapsulation the only ISP information you need is a login name and password. If you are using RFC 1483,
you do not need a login name or password.
