3.13.3 Dial to a Single ISP/Dial to Dual ISPs

Select

Dialing to a Single ISP

if you access the Internet via a single ISP.

ISP Access Setup

ISP Name -

Enter your ISP name such as Seednet, Hinet and

so on.

Dial Number -

Enter the ISDN access number provided by

your ISP.

Username -

Enter the username provided by your ISP.

Password -

Enter the password provided by your ISP.

Require ISP Callback (CBCP) -

If your ISP supports the

callback function, check this box to activate the Callback

Control Protocol during the PPP negotiation.

Scheduler (1-15) -

Enter the index of schedule profiles to

control the Internet access according to the preconfigured

schedules. Refer to section

3.7.2 Schedule

for detailed

configuration.

PPP/MP Setup

Link Type

–

There are three link types provided here for

different purpose.

Link Disable

disables the ISDN dial-out

function.

Dialup 64Kbps

allows you to use one ISDN B

channel for Internet access.

Dialup 128Kbps

allows you to

use both ISDN B channels for Internet access.

Dialup BOD

(for detailed information of configuration, please refer to

section

3.10.5

) stands for bandwidth-on-demand. The router

will use only one B channel in low traffic situations. Once the

single B channel bandwidth is fully used, the other B channel

will be activated automatically through the dialup. For more

detailed BOD parameter settings, please refer to the section of

Call Control

.

PPP Authentication -

PAP only allows you to configure the

PPP session to use the PAP protocol to negotiate the username

and password with the ISP.

PAP or CHAP

is to configure the

PPP session to use the PAP or CHAP protocols to negotiate

the username and password with the ISP.

Idle Timeout -

Idle timeout means the router will be

disconnect after being idle for a preset amount of time. The

default is 180 seconds. If you set the time to 0, the ISDN

connection to the ISP will always remain on.

IP Address Assignment

Method (IPCP)

In most environments, you should not change these settings as

most ISPs provide a dynamic IP address for the router when it

connects to the ISP. If your ISP provides a fixed IP address,

check

Yes

and enter the IP address in the field of

Fixed IP

Address

.

Select

Dialing to Dual ISPs

if you have more than one ISP. You will be able to dial to both

ISPs at the same time. This is mainly for those ISPs that do not support Multiple-Link PPP

(ML-PPP). In such cases, dialing to two ISPs can increase the bandwidth utilization of the

ISDN channels to 128kbps data speed.

Common Settings

Enable Dual ISPs Function -

Check to enable the Dual ISPs

function.

Require ISP Callback (CBCP) -

If your ISP

supports the callback function, check this box to activate the

Callback Control Protocol during the PPP negotiation.

Primary ISP Setup

ISP Name -

Enter your ISP name.

Dial Number -

Enter the ISDN access number provided by

your ISP.

Username -

Enter the username provided by your ISP.

Password -

Enter the password provided by your ISP.

IP Address Assignment

Method (IPCP) for

primary ISP setup

In most environments, you should not change these settings

as most ISPs provide a dynamic IP address for the router

when it connects to the ISP. If your ISP provides a fixed IP

address, check

.

Secondary ISP Setup)

ISP Name -

Enter the secondary ISP name.

Dial Number -

Enter the ISDN access number provided by the

ISP.

Username -

Enter the username provided by your ISP.

Password -

Enter the password provided by your ISP.

After entering the necessary settings and clicking

OK

, you will see

Goto ISDN Diagnostic

link appears on the bottom of the webpage. To have an ISDN connection, please click this

link.

Now, the system will guide you to click

Dial

ISDN

. Wait for a moment after clicking the

dial link. Then, a successful ISDN connection will be shown as the following.

3.13.4 Call Control

Some applications require that the router (only for the ISDN models) be remotely activated,

or be able to dial up to the ISP via the ISDN interface. Vigor routers provide this feature by

allowing user to make a phone call to the router and then ask it to dial up to the ISP.

Accordingly, a teleworker can access the remote network to retrieve resources. Of course, a

fixed IP address is required for WAN connection and some internal network resource has to

be exposed for remote users, such as FTP, WWW.

Call Control Setup

Dial Retry -

It specifies the dial retry counts per triggered

packet. A triggered packet is the packet whose destination is

outside the local network. The default setting is no dial retry.

If set to 5, for each triggered packet, the router will dial 5

times until it is connected to the ISP or remote access router.

Dial Delay Interval -

It specifies the interval between dialup

retries. By default, the interval is 0 second.

Remote Activation –

It can help users who would like to

Page 195 / 304

VigorPro5300 Series User’s Guide

187

access the server which is off the Internet in the head office.

To remotely make the server to be available on the Internet, i.e.

make the router in the head office activating its Internet access

either by dialing-up or starting broadband connection, users

can make a regular phone call (the number is set in the

Remote Activation field) to the router as signaling it for

activation. The phone call will be soon disconnected once the

router is on line.

Note that

Dialing to a Single ISP

should be pre-configured

properly.

Basic Setup

Link Type -

Because ISDN has two B channels (64Kbps/per

channel), you can specify whether you would like to have

single B channel, two B channels or BOD (Bandwidth on

Demand). Four options are available: Link Disable, Dialup

64Kbps, Dialup 128Kbps, Dialup BOD.

PPP Authentication -

It specifies the PPP authentication

method for PPP/MP connections. Normally you can set it to

PAP/CHAP for better compatibility.

TCP Header Compression - VJ Compression

: It is used for

TCP/IP protocol header compression. Normally it is set to Yes

to improve bandwidth utilization.

Idle Timeout -

Because our IDSN link type is

Dial On

Demand

, the connection will be initiated only when needed.

Bandwidth-On-Demand

(BOD) Setup

Bandwidth-On-Demand is for Multiple-Link PPP \(ML-PPP

or MP). The parameters are only applied when you set the

Link Type

to

Dialup BOD

. The ISDN usually use one B

channel to access the Internet or remote network when you

choose the Dialup BOD link type. The router will use the

parameters here to decide on when you activate/drop the

additional B channel. Note that

cps

(characters-per-second)

measures the total link utilization.

High Water Mark and High Water Time -

These

parameters specify the situation in which the second channel

will be activated. With the first connected channel, if its

utilization exceeds the High Water Mark and such a channel

is being used over the High Water Time, the additional

channel will be activated. Thus, the total link speed will be

128kbps (two B channels).

Low Water Mark and Low Water Time -

These parameters

specify the situation in which the second channel will be

dropped. In terms of the two B channels, if their utilization is

under the Low Water Mark and these two channels are being

used over the High Water Time, the additional channel will be

dropped. As a result, the total link speed will be 64kbps (one

B channel).
