Technical Reference
This section provides some technical background information about the topics
covered in this chapter.
5.3.1
Encapsulation
Be sure to use the encapsulation method required by your ISP. The ZyXEL Device
supports the following methods.
5.3.1.1
PPP over Ethernet
The ZyXEL Device 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.
For the service provider, PPPoE offers an access and authentication method that
works with existing access control systems (for example RADIUS).
One of the benefits of PPPoE is the ability to let you access one of multiple network
services, a function known as dynamic service selection. This enables the service
provider to easily create and offer new IP services for individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as
it requires no specific configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the ZyXEL Device (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
Sustain Cell
Rate
The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that
can be transmitted. Type the SCR, which must be less than the PCR.
Note that system default is 0 cells/sec.
This field is available only when you select
Non Realtime VBR
or
Realtime VBR
.
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.
This field is available only when you select
Non Realtime VBR
or
Realtime VBR
