Encapsulation Be sure to use the encapsulation method required by your ISP. The ZyXEL Device can work in bridge mode or routing mode. When the ZyXEL Device is in routing mode, it supports the following methods. IP over Ethernet IP over Ethernet (IPoE) is an alternative to PPPoE. IP packets are being delivered across an Ethernet network, without using PPP encapsulation. They 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 Ethernet cells. PPP over Ethernet Point-to-Point Protocol over Ethernet (PPPoE) provides access control and billing functionality in a manner similar to dial-up services using PPP. PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. 100 ADSL Series User's Guide

Technical Reference

The following section contains additional technical information about the ZyXEL Device features

described in this chapter.

Encapsulation

Be sure to use the encapsulation method required by your ISP. The ZyXEL Device can work in

bridge mode or routing mode. When the ZyXEL Device is in routing mode, it supports the following

methods.

IP over Ethernet

IP over Ethernet (IPoE) is an alternative to PPPoE. IP packets are being delivered across an

Ethernet network, without using PPP encapsulation. They 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 Ethernet cells.

PPP over Ethernet

Point-to-Point Protocol over Ethernet (PPPoE) provides access control and billing functionality in a

manner similar to dial-up services using PPP. PPPoE is an IETF standard (RFC 2516) specifying how

a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.)

connection.

Encapsulation Mode

The encapsulation method of multiplexing used by your is

LLC/SNAP-BRIDGING

. In

LCC encapsulation, bridged PDUs are encapsulated by identifying the type of the

bridged media in the SNAP header.

Service Category

Select

UBR Without PCR

for applications that are non-time sensitive, such as e-mail.

Select

CBR

(Constant Bit Rate) to specify fixed (always-on) bandwidth for voice or

data traffic.

Select

Non Realtime VBR

(non real-time Variable Bit Rate) for connections that do

not require closely controlled delay and delay variation.

Select

Realtime VBR

(real-time Variable Bit Rate) for applications with bursty

connections that require closely controlled delay and delay variation.

Peak Cell Rate

Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak Cell

Rate (PCR). This is the maximum rate at which the sender can send cells. Type the

PCR here.

Sustainable 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.

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.
