The Advanced Screen

Use the

Advanced

screen to enable or disable ADSL over PTM, Annex M, DSL PhyR, and SRA

(Seamless Rate Adaption) functions. The Device supports the PhyR retransmission scheme. PhyR is

a retransmission scheme designed to provide protection against noise on the DSL line. It improves

voice, video and data transmission resilience by utilizing a retransmission buffer.

ADSL over PTM

Select

Enable

to use ADSL over PTM. Since PTM has less overhead than ATM, some ISPs

use ADSL over PTM for better performance.

Annex M

You can enable

Annex M

for the Device to use double upstream mode to increase the

maximum upstream transfer rate.

PhyR US

Enable or disable

PhyR US

(upstream) for upstream transmission to the WAN. PhyR US

should be enabled if data being transmitted upstream is sensitive to noise. However,

enabling PhyR US can decrease the US line rate. Enabling or disabling PhyR will require the

CPE to retrain. For PhyR to function, the DSLAM must also support PhyR and have it

enabled.

Technical Reference

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

in this chapter.

Encapsulation

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

or routing mode. When the 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 ATM (PPPoA)

PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA connection

functions like a dial-up Internet connection. The Device encapsulates the PPP session based on

RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the Internet Service

Provider’s (ISP) DSLAM (digital access multiplexer). Please refer to RFC 2364 for more information

on PPPoA. Refer to RFC 1661 for more information on PPP.

PPP over Ethernet (PPPoE)

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.

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 Device (rather than individual computers), the computers on

the LAN do not need PPPoE software installed, since the Device does that part of the task.

Furthermore, with NAT, all of the LANs’ computers will have access.

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 RFC 1483 for more detailed

information.

Multiplexing

There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to

use the multiplexing method required by your ISP.

VC-based Multiplexing

In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit; for

example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where

dynamic creation of large numbers of ATM VCs is fast and economical.

LLC-based Multiplexing
