In the

Connection name

field, specify a name for the connection for easier identification.

For ADSL WAN connection, fill in the

VPI

and

VCI

fields.

As a rule, the specified settings are enough to configure a connection of the selected type. If you

need to specify additional settings, open the expert settings mode. To do this, use the switch in the

bottom left corner of the page. After switching to the expert settings mode, the following sections

are displayed:

ATM

(for ADSL WAN connection),

Ethernet

(for Ethernet WAN connection), and

VLAN

.

Parameter

Description

Connection name

A name for connection for easier identification.

ATM

VPI

Virtual Path Identifier.

The valid range is from 0 to 250.

VCI

Virtual Circuit Identifier.

The valid range is from 32 to 65535.

Encapsulation Mode

Select

LLC

or

VC

from the drop-down list.

QoS

A class of traffic for this connection.

UBR

(

Unspecified Bit Rate

): The UBR service is used for applications

that allow various delays and losses of packets. It is appropriate to

use the UBR service for text/data/image transfer applications, as

well as messaging, distribution, retrieval, and remote terminal

applications.

UBR With PCR

(

Unspecified Bit Rate with Peak Cell Rate

): The UBR service is

used for applications that allow various delays and losses of packets.

The Peak Cell Rate is a determining factor in how often cells are

sent in an effort to minimize lag or jitter caused by traffic

inconsistencies. When you select this value from the drop-down list,

the

Peak Cell Rate

field is displayed. Specify a required value (in

cells per second).

CBR

(

Constant Bit Rate

): This service is used for applications that

require a constant data rate. It is mostly used for transferring

uncompressed audio and video, e.g. videoconferencing, interactive

audio (telephony), audio/video distribution (television, distance

education, e-shops), and retrieval (video-on demand, audio

libraries). When you select this value from the drop-down list, the

Peak Cell Rate

field is displayed. Specify a required value (in

cells per second).

Non Realtime VBR

(

Non-Real-time Variable Bit Rate

): This service can be used for

transferring data that have critical response-time requirements, e.g.

air ticket booking, bank transactions, and process monitoring. When

you select this value from the drop-down list, the

Peak Cell Rate

,

Sustainable Cell Rate

, and

Maximum Burst Size

fields are

displayed. Specify required values.

Realtime VBR

(

Real-time Variable Bit Rate

): This service is used for delay-

sensitive applications such as real time video. The Rt-VBR provides

higher network flexibility than the CBR service. When you select

this value from the drop-down list, the

Peak Cell Rate

,

Sustainable Cell Rate

, and

Maximum Burst Size

fields are

displayed. Specify required values.

VLAN

Allow to create several

connections assigned

to this port

Select the checkbox to allow the router to use several untagged

connections.

Use VLAN

Select the checkbox to allow the router to use tagged VLAN

connections.

VLAN ID

An identifier for the VLAN. The field is displayed when the

Use

VLAN

checkbox is selected.

VLAN priority

A priority tag for the type of traffic transmitted. The field is

displayed when the

Use VLAN

checkbox is selected.
