4.1.2 Encapsulation and Multiplexing Scenarios

For Internet access you should use the encapsulation and multiplexing methods used by your ISP. For
LAN-to-LAN applications, for example, between a branch office and corporate headquarters, prior
agreement on methods is necessary because encapsulation and multiplexing cannot be automatically
determined. What method(s) you use depends on how many VCs you have and how many different network
protocols you need. Here are some examples of more suitable combinations in such an application.
Scenario 1. One VC, One Protocol (IP)
Selecting RFC-1483 encapsulation with VC-based multiplexing requires the least amount of overhead (0
octets). However, if there is a potential need for multiple protocol support in the future, you need to
reconfigure either computer later.
Scenario 2. Multiple VCs
If you have an equal number (or more) of VCs than the number of protocols, then select RFC-1483
encapsulation and VC-based multiplexing.
Nailed-Up Connection (PPPoE)
A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand.
The Prestige does two things when you specify a nailed-up connection.
The first is that idle timeout is disabled.
