Advanced Setup

This section contains advanced setup settings. To create a connection you need to define the

Layer 2 interface and the WAN service.

Configuration Types

ADSL is an ATM based technology. The 65xx family of routers support Bridging and Ethernet

over ATM (EoA) configurations and ATM based configurations:

•

Bridging

Bridging (Layer 2 MAC addressing); uses Ethernet frames.

•

PPPoE

Point to Point Protocol over Ethernet; encapsulates PPP packet in Ethernet. (RFC 2516)

•

IPoE

IP over Ethernet (Layer 3 Internet Protocol addressing in Ethernet frames)

•

PPPoA

Point to Point Protocol over ATM, encapsulates PPP frames in ATM adaption layer 5 (AAL5)

packets.

•

IPoA

IP over ATM (Layer 3 Internet Protocol addressing in AAL5 packets

To configure a connection, you first configure the connection type. EoA, PPPoA, or IPoA.

1.

Add a Layer 2 interface and select the connection type.

EoA is used for PPPoE, IPoE and Bridge connections. PPPoA and IPoA are AAL5 based

connections

2.

Set the WAN interface

The WAN interface options to select are determined by the Layer 2 interface type.

Add an ATM Layer 2 Interface

1.

In the left hand menu pane, click

Advanced Setup

.

2.

Under Advanced Setup, click Layer2 Interface then ATM Interface, then click the

Add

button.

3.

In the

VPI

and

VCI

text boxes enter appropriate VPI/VCI numbers.

VPI/VCI (Virtual Path Identifier/Virtual Circuit Identifier) values essentially define the “pipe”

which sends data from the upstream device to the modem/router. The VPI/VCI values will be

given to you by your ISP.

4.

Under

Select DSL Link

Type

select the appropriate DSL link type:

5.

For the EoA options you may select a connection mode:

Default Mode

: a single service over the one connection

VLAN MUX Mode

: multiple VLAN services over the one connection

6.

From the

Encapsulation Mode

drop down select the appropriate option

:

For

EoA

options (PPPoE, IPoE, Bridge) select

LLC/SNAP BRIDGING

For

PPPoA

select

VC/MUX

For

IPoA

select

LLC/SNAP ROUTING

7.

From the

Service Category

drop down select the type of service

The service category selection will be provided by your ISP. The service category defines

five classes of traffic:

±

UBR Without PCR

(Unspecified Bit Rate without Peak Cell Rate)—UBR service is

suitable for applications that can tolerate variable delays and some cell losses.

Applications suitable for UBR service include text/data/image transfer, messaging,

distribution, and retrieval and also for remote terminal applications such as

telecommuting.

±

UBR With PCR

(Unspecified Bit Rate with Peak Cell Rate).

•

Specify a Peak cell Rate Peak cell rate is 1-3442 (cells / sec).

±

CBR

(Constant Bit Rate)—used by applications that require a fixed data rate that is

continuously available during the connection time.

It is commonly used for

uncompressed audio and video information such as videoconferencing, interactive audio

(telephony), audio / video distribution (e.g. television, distance learning, and pay-per-

view), and audio / video retrieval (e.g. video-on-demand and audio library).

•

Specify a Peak cell Rate. The Peak Cell Rate is rate is 1-3442 (cells / sec).

±

Non Realtime VBR

(Non-Real-time Variable Bit Rate)—can be used for data transfers

that have critical response-time requirements such as airline reservations, banking

transactions, and process monitoring.

•

Specify a Peak cell Rate. 1-3442 (cells / sec).

•

Sustainable Cell Rate. 1-3442 (cells / sec).

•

Maximum Burst Size. The maximum number of contiguous cells that can be sent

at the Peak Cell Rate. 1-1000000 (cells / sec)

±

Realtime VBR

(Real-time Variable Bit Rate)—used by time-sensitive applications such

as real-time video. Rt-VBR service allows the network more flexibility than CBR.

•

Specify a Peak cell Rate. 1-3442 (cells / sec).

•

Sustainable Cell Rate. 1-3442 (cells / sec).

•

Maximum Burst Size. The maximum number of contiguous cells that can be sent

at the Peak Cell Rate. 1-1000000 (cells / sec)

8.

If using UBR without PCR, select the

IP Quality of Service (QoS) algorithm

. Either

Strict

Priority

or

Weighted Fair Queuing.

Add an Ethernet Layer 2 Interface

The system allows you specify any Ethernet interface as a WAN interface.
