Note: About ISDN TA Setup

Unlike most modems, ISDN initial strings vary between different ISDN TAs and there
is no “Standard ISDN TA” initial string. If your ISDN TA is not listed in the modem
selection list, you must find out what your ISDN TA initial string is. Your ISDN TA’s
initial string should be listed in your ISDN TA user’s manual. There are probably many
initial strings listed for your ISDN TA. The one you are looking for is Asyn-to-Sync PPP
(Asynchronous to Synchronous PPP). You can enter this initial string if you would like
to use only one channel of your ISDN TA. If you would like to bundle both channels of
your ISDN TA together, you need to use a different initial string called Multilink-PPP.

You should also verify that your ISDN TA supports the Dial-up string ATDT. Most ISDN
TAs will support ATDT and usually the rest will support ATD or ATDI.

Please also note that to bundle the two channels of your ISDN TA together, you must
enter the two phone numbers in the Telephone Number.

power off and power on the Modem after changing the string.

Basically default AT command is “AT&F” and is available for most modems, but some
modems had its own initial AT command due to changeable serial port rate and you can
find this information on their user’s manual. (For Example, US Robotics modem initial
string is “AT&F1B1 )

For no dial tone telephone system, your initial AT command should add “X1” as
“AT&FX1”

Test the Modem in Diagnostics window of Telnet.

You can also use Ping command in MS-DOS mode to verify the network connection:

l Ping 127.0.0.1 to see if the TCP/IP stack is properly configured.

l Ping gateway IP (Default: 192.168.1.1) to check if the internal link of network

works.

l Ping DNS IP and observe whether the modem will dial or not, to check the
external link and modem connection.

l Ping a Internet domain name (Example: www.yahoo.com) to see if DNS works.

When dialing into the
AOpenRouter 101/201, the
Modem does not seem to
connect.

Miscellaneous

I cannot get IP from

AOpenRouter 101/201.

I have another DHCP server on
my LAN

Make sure that you are on the AOpenRouter 101/201 Dial-in User list.

Modem 2 cannot be enabled.

Check the rear panel of the device, the MODEM 2/CONFIG Switch must be set on the
MODEM 2.

If the Bandwidth-on-demand is set on the bandwidth allocation, lower down the
percentage of MODEM1 in the rule dialogue¡]the default setting is at 50%¡^.

If the AOpenRouter 101/201 DHCP server on the Intranet page. If your LAN can access
the Internet in default, we suggest that you disable your pre-existing DHCP server
services or separates them into two different segments.

Appendix B Glossary

DHCP

DHCP is a protocol for automatic IP configuration. Client side computer can get one IP
from DHCP server automatically. Using DHCP can save the effort of setting IP for
every LAN computers.

Dial-in

Dial in is the function for remote user to access office LAN by Modem/ISDN TA
connection. Just like you dial up to ISP, Gateway Hub can act as a small ISP that
telecommuter and travelling employee can access LAN using standard dial up
program.

Dial-up Access

Refers to connecting a device to a network via a modem and a public telephone
network. Dial-up access is really just like a phone connection, except that the parties
at the two ends are computer devices rather than people. Because dial-up access
uses normal telephone lines, the quality of the connection is not always good and data
rates are limited, but new technologies such as ISDN are providing faster rates.

An alternative way to connect two computers is through a leased line, which is a
permanent connection between two devices. Leased lines provide faster throughput
and better quality connections, but they are also more expensive.

Domain Name

A name that identifies one or more IP addresses. For example, the domain name
microsoft.com represents about a doze IP addresses. Domain names are used in
URLs to identify particular Web pages. For example, in the URL
http://www.pcwebopedia.com/index.html, the domain name is pcwebopedia.com.

IEEE

Abbreviation of Institute of Electrical and Electronics Engineers, pronounced I-triple-E.
Founded in 1884, the IEEE is an organization composed of engineers, scientists, and
students. The IEEE is best known for developing standards for the computer and
electronics industry. In particular, the IEEE 802 standards for local-area networks are
widely followed.

Internet

A global network connecting millions computers. As of 1998, the Internet has more
than 100 million users worldwide, and that number is growing rapidly. More than 100
countries are linked into exchanges of data, news and opinions.

40

Intranet

A network based on TCP/IP protocols (an internet) belonging to an organization,
usually a corporation, accessible only by the organization's members, employees, or
others with authorization.

IP Address

An identifier for a computer or device on a TCP/IP network. Networks using the
TCP/IP protocol route messages based on the IP address of the destination. The
format of an IP address is a 32-bit numeric address written as four numbers separated
by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an
IP address.

ISDN

Abbreviation of integrated services digital network, an international communications
standard for sending voice, video, and data over digital telephone lines. ISDN requires
special metal wires and supports data transfer rates of 64 Kbps (64,000 bits per
second).

ISP

Short for Internet Service Provider, a company that provides access to the Internet.
For a monthly fee, the service provider gives you a software package, username,
password and access phone number. Equipped with a modem, you can then log on to
the Internet and browse the World Wide Web and USENET, and send and receive e­mail.

Local Area Network (LAN)

A computer network that spans a relatively small area. Most LANs are confined to a
single building or group of buildings. However, one LAN can be connected to other
LANs over any distance via telephone lines and radio waves. A system of LANs
connected in this way is called a wide-area network (WAN)

MAC Address

Short for Media Access Control address, a hardware address that uniquely identifies
each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of
the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC)
layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly
with the network media. Consequently, each different type of network media requires a
different MAC layer.

PPP

41

PPP (Point-to-Point protocol) is a communications protocol for transmitting information
over standard telephone lines. A PPP account is a dial-up account used to connect to
the Internet. It is a dial-up account actually calls another computer to gain Internet
access.

PAP/CHAP ISP

PAP stands for Password authentication protocol. CHAP means Challenge
handshake authentication protocol. Most ISP use either one for user identification. If
your ISP doesn’t support these two protocols, contact ISP for authentication script.
You have to key in script to IP Gateway.

TCP/IP

Acronym for Transmission Control Protocol/Internet Protocol, the suite of
communications protocols used to connect hosts on the Internet. TCP/IP uses several
protocols, the two main ones being TCP and IP.

Telnet

A terminal emulation program for TCP/IP networks such as the Internet. The Telnet
program runs on your computer and connects your PC to a server on the network. You
can then enter commands through the Telnet program and they will be executed as if
you were entering them directly on the server console. This enables you to control the
server and communicate with other servers on the network. To start a Telnet session,
you must log in to a server by entering a valid username and password.
