6.4 WAN Technical Reference
This section provides some technical background information about the topics
covered in this chapter.
6.4.1 Encapsulation
Be sure to use the encapsulation method required by your ISP. The P-660H-T1v3s
supports the following methods.
6.4.1.1 ENET ENCAP
The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented
with the IP network protocol. IP packets are routed between the Ethernet interface
and the WAN interface and then formatted so that they can be understood in a
bridged environment. For instance, it encapsulates routed Ethernet frames into
bridged ATM cells.
6.4.1.2 PPP over Ethernet
The P-660H-T1v3s supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE
is an IETF Draft standard (RFC 2516) specifying how a personal computer (PC)
interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The
PPPoE option is for a dial-up connection using PPPoE.
Maximum Burst Size Maximum Burst Size (MBS) refers to the maximum number of
cells that can be sent at the peak rate. Type the MBS, which is
less than 65535.
MTU
MTU
The Maximum Transmission Unit (MTU) defines the size of the
largest packet allowed on an interface or connection. Enter the
MTU in this field.
For ENET ENCAP, the MTU value is 1500.
For PPPoE, the MTU value is 1492.
For PPPoA and RFC, the MTU is 65535.
