Essentials of Dial
-
up Networking for Connecting to Internet or Railnet from home PC on Windows

(Very Brief)


1.1.

Internet

Simply putting, Internet is a net of nets. Each net, in turn, is another net of nets or computers. Millions
of such computers, operating
on different Operating Systems (Windows 95, 98 or 2000, Unix, Xenix, Linux
etc.), storing files and data in different formats are, yet, able to inter
-
change data with each other.

1.2.

How are they uniquely identified in the whole system to avoid confusion (IP a
ddress)

Numbers easiest handle large volumes, and so, there is a scheme of uniquely identifying each (authorised) computer
on the Internet by assigning it a number (which is actually four numbers separated by dots, like A.B.C.D


each of A, B,
C and D can
be from 0 to 255). This representation is called dotted
-
decimal notation. These unique numbers to any
computer are supplied by a Committee of experts (on payment of a fee). The more such IDs you want, greater is the fee
to be paid. E.g. 202.69.11.128


rep
resents one such unique number. There are a few series of numbers, which are left
free for anybody to use, BUT ONLY FOR THEIR LOCAL NETWORKING and NOT TO CONNECT TO THE
INTERNET. These series are


10.0.0.0 to 10.255.255.255 (one class A net); 172.16.0.0 t
o 172.31.255.255 (16 class B
nets); 192.168.0.0 to 192.168.255.255 (256 class C nets). The ISP (Internet Service Provider) has one such number
allotted to it (which he uses on his computer installed as his server), and another range of numbers, in addition
, one of
which the server
-
computer assigns to your computer (for a temporary period) when and while you are connected to it.
The same number is allotted to another person, when you have disconnected. This ID is called IP address (Internet
Protocol address)
.

1.3.

How are computers connected to each other

There are two basic types of connecting methods to any network





DCC

(Direct Cable Connection), which is up and running as soon as a computer is switched on through a
(special) network
-
card in the computer to wh
ich is connected one (or more) cables leading to other
computer(s). Of course, in such a system of inter
-
connected computers, at least one computer has to take
the lead in directing all computers (to behave) which is called the Server. The speed of data
-
tr
ansfer in
such a connection is (say) 1000 (or more!) times more than the other type of connection (which is
described below), but so is the cost. (This type of connection is not discussed any more).



Dial
-
up network connection
(also called NOD, or Network
-
o
n
-
Demand) is a way to connect to another
computer from your computer over telephone lines, for which you should have the following:
-

o

A computer.

o

A modem (external or internal).

o

A telephone line (normally DOT; or RLY if you have access (i.e. username and p
assword) to Railnet
server).

o

Necessary cables for inter
-
connecting these, supplying power to them etc.

o

An internet connection username and password (either through DOT or through Railnet).

(Assumption : You have a computer with Windows 95, 98 or 2000 insta
lled; and a web
-
browser loaded on it.)

1.4.

What else should the computer have for a dial
-
up connection to internet/railnet

For a connection to another computer (and through it to a network) the computer must have


a modem, telephone
connection, an account on
the net. The other computer (called a server) must also have a modem and a telephone line.

1.5.

What is to be done on my computer to start such a connection

Here you will need to (details of how to do it are given further ahead):
-



Install Dial
-
up Adapter (if n
ot already installed). Set its properties.


This is a software component
which enables your computer’s mother
-
board to utilise



Connect and install modem and its driver (if not already installed). Set its properties.



Install TCP/IP protocol (if not already

installed). Set its properties.



Install Client (‘Client for Microsoft Networks’) (if not already installed). Set its properties.



Install (
only those which are required
) services (if not already installed). Set their properties. You
may not require any ser
vices on your computer


these are required if you want to share your hard
-
disk, files, printer etc. (and you better not do it on any net without being sure of what you are doing!)



Connect the telephone line.



Make a dial
-
up connection.



Go to Internet!

The
above may be installed in any order as long as you restart the machine at least once after entire configuration is
over. On being prompted for restarting the computer, you can postpone it till you have set everything right and restart
only once in the end.

If not restarting every time, you must confirm for all settings to be as desired by you, after
restarting.

1.6.

Where to find the Control Panel

Any new hardware is automatically detected and installed by Plug
-
and
-
Play feature. However, if the hardware was
rele
ased in the market after the release of the Windows version you are using, its correct driver will not be in the
standard Windows cabinet of drivers, and it will install a default driver (which will work but not giving the optimal
performance; to get the b
est performance you will have to install the driver supplied by the manufacturer (OEM) in a
floppy or CD).

You can install and configure individual items through
‘Control Panel’

found through



Start button


卥St楮is

up Adapter

or change its properties (remember this is not a piece of any hardware, it is just
a software portion of Windows itself which enables motherboard to figure out that data coming in on a
particular port is (say, not from

a keyboard or mouse but) from a network object)
-

use
Network

in
Control panel (you will do this for Dial
-
up Adapter).

Explorer or My Computer.

1.8.

How to add my modem and its driver

1.

Connect

your
modem

to the
computer

and
power
-
supply

(but not necessarily to the telephone line
yet). It can be connected to the computer’s LPT port or COM port


for this (modern) modems
have a
hydra
-
head cable, with only one connector at one end (this fits into the modem) and two connectors
emanating from a single cable on the other (one of which can fit into the LPT port of your computer,
and the other in a COM port, connect it to whiche
ver is free).

2.

Turn on

the power supply for computer (if not already on) and the modem. Keep Windows 95 or 98
compact disk ready at hand (your computer may ask for it).

3.

Go to Modems

in Control panel. Note that it has two TABs


General, Diagnostics. In Gene
ral Tab,
press add button. (You may remove earlier installations by selecting them one by one, if not wanted).

4.

The modem installation wizard will start. Follow instructions step by step. (If you want to install your
own driver for the modem, select ‘Don’t
detect my modem; I’ll select it from a list.’ And click on
Next.)

5.

When presented with a list, select the manufacturer and then, model of your modem (or nearest
equivalent to it). You can also choose ‘Have Disk’ and then give it the path of where the wanted

driver
is located. Follow further instructions step by step.

6.

This will complete the installation of your modem and its driver with default options (which should
normally work the best for you).

7.

After installation, select the modem you’ve installed and cli
ck on properties. On the General tab, set
the desired level of volume (can be changed later on too) and speed (leave it at the default value, or set
it at the maximum value appearing in the drop down list).


The modem will connect at the best possible spe
ed. Some modems may have the option to ‘Connect only at this
speed’


to be used if you do not want your telephone line to be used at speeds below what you set here, in such
cases if modem is not able to re
-
establish the specified speed in a few seconds, i
t will disconnect the line.



8.

Now go to Diagnostics tab (so far, what you had been doing was on the General Tab) in the Modem
Properties window.

9.

Select the modem you have just installed and click on ‘More Info…’. It will test your modem and give
the results
in another window (as long as a response is shown from first two pins, the modem will
function; better functioning is reflected by a response from all pins). Come back to the General Tab.

10.

Next you have to set
-
up the Dialling properties. These are independe
nt of the modem you are using
(and are common for all modems). Press the ‘Dialling Properties’ button on the General Tab. Fill in the
details as required


‘I am Dialling from’; ‘I am in this country’; ‘Area code’; ‘For local calls dial’;
‘For long distanc
e calls dial’; ‘To disable call waiting dial’; ‘Dial using’ {Tone or Pulse}; and Calling
card details (if used). Leave fields not applicable blank. When you are on net, you may take a long
time in completing your work, so call
-
waiting should be disabled no
t to irritate people who happen to
call you in the interim period and (impatiently) wait for you to complete your previous call!

Your modem is now set up.

1.9.

How to add Dial
-
up Adapter and what properties/values to set

1.

Turn on

the power supply for computer. K
eep Windows 95 or 98 compact disk ready at hand (your
computer may ask for it).

2.

Go to Network

in Control panel. Note it has three TABs


Configuration, Identification and Access
Control. In Configuration Tab, press ‘Add’ button.

3.

You are presented a new win
dow containing


Client, Protocol, Adapter, and Service. Select Adapter,
and press Add.

4.

You are presented another new window


in this, on left side select Microsoft, then, on right side,
select Dial
-
up Adapter. Press OK.

5.

Insert the Windows 95/98 CD on bei
ng asked for it. Follow instructions.

6.

Your Dial
-
up Adapter with default properties is installed.

In Windows 95, Dial
-
up Networking was not a standard component, and was provided on a separate add
-
on CD
(called the Value Added Pack). You must possess this
if you are using Windows 95. IN Windows 98, the
Windows 98 CD itself included it. In Windows ME (Millennium Edition), the adapter is installed by default. The
installation of Adapters on Windows ME is required to be done through
Add new Hardware
.

7.

The defau
lt properties will work satisfactorily, however, in trouble
-
shooting (later ever) if you need to
verify correct settings these are (To access these for viewing or modification, select the Dial
-
up
Adapter and then click on properties button, it will present

you a new window called ‘Dial
-
up
Adapter Properties’ having three TABs


‘Driver Type’, ‘Bindings’ and ‘Advanced’)




‘Driver Type’ Tab


‘Enhanced mode (32 bit and 16 bit) NDIS driver’ should be ticked on.



‘Bindings’ Tab


‘TCP/IP


Dial
-
up Adapter’

shoul
d be ticked on. (If TCP/IP is not yet installed,
this will not be found. It will be automatically added when TCP/IP is installed).

This binding implies, that the TCP/IP language (of communication between devices) is to be used in
conjunction with Dial
-
up
Adapter.



‘Advanced Tab’


‘Enable Point to Point IP’ should be Yes; ‘IP Packet size’ should be automatic
(different systems use Large, medium or small; so leave it automatic); Record a log file may be
Yes or No (No is faster); Use IPX header compression ma
y be Yes or No (Yes is faster).



Click OK to come back to (the main) Network Tab.

1.10.

How to add TCP/IP and what property/values to set

1.

Turn on

the power supply for computer. Keep Windows 95 or 98 compact disk ready at hand (your
computer may ask for it).

2.

Go to

Network

in Control panel. Note it has three TABs


‘Configuration’, ‘Identification’ and
‘Access Control’. In Configuration Tab, press ‘Add’ button.

3.

You are presented a new window containing


Client, Protocol, Adapter, and Service. Select Protocol,
and p
ress Add.

4.

You are presented another new window


in this, on left side select Microsoft, then, on right side,
select TCP/IP. Press OK.

5.

Insert the Windows 95/98 CD on being asked for it. Follow instructions.

6.

Your TCP/IP protocol suite (because it is a colle
ction of, say, several languages that computer devices
use amongst each other) with default properties is installed. It will be automatically bound to all
existing installed network adapters (including Dial
-
up Adapter).

7.

To set the Properties, come to Netwo
rk Tab, select TCP/IP and click on properties. (REMEMBER


TCP/IP settings are required differently for different networks, so these properties are required to be
set separately for individual Protocol


Adapter pairs). (FURTHER


for Dial
-
up Adapter, if y
ou are




dialling into different networks, there would be many connections (for example, DOT for Internet and
RLY for Railnet). In such a case, these properties should be set differently for each connection (and
this is done in each connection’s properties),

as properties set here for the Protocol

pair), will apply to all your telephone connections (which
wouldn’t be what you wanted, as DOT and RLY connections would behave differently)!

8.

HINT


Leave t
he properties of
TCP/IP

here as default, without changing any
of them. Setting of these properties in individual telephone connections is explained below.

In Windows 95, Dial
-
up Networking was not a standard component, and was provided
on a separate add
-
on CD
(called the Value Added Pack). You must possess this if you are using Windows 95. IN Windows 98, the
Windows 98 CD itself included it. In Windows ME (Millennium Edition), the adapter is installed by default. The
installation of Adap
ters on Windows ME is required to be done through
Add new Hardware
.

9.

Come back to Network (main) tab. Go to Identification tab. You can give your computer’s
identification detail (as you wish) here, or leave them all blank.

10.

Go to Access Control Tab


if you

wish to share your files and printers, then you need to specify here
whether the sharing will ‘Share
-
level access control’ or ‘User
-
level access control’. Leave it as
‘Share
-
level access control’.

11.

Come back to ‘Configuration’ Tab. Here you see ‘Primary Ne
twork Logon’ section


select ‘Client
for Microsoft Networks’ (this means that your computer is going to be a client to Microsoft networks,
to which it will connect by dialling or through DCC, this option lets the computer identify you to the
networks you
are connecting to and do some other mandatory processing).

12.

Now press the ‘File and Printer sharing button’


In a new window you will be presented two options,
keep them both off


‘I want to be able to give others access to my files.” and “I want to be ab
le to
allow others to print to my printer(s)’. (You would want neither from your home!).

13.

(At Last!) You are now done with TCP/IP installation and configuration.

1.11.

How to make a new telephone connection on my computer and what properties/value(s) to set

1.
T
urn on

the power supply for computer. Modem will be required when testing your connection, you
may switch it on then. Keep Windows 95 or 98 compact disk ready at hand (your computer may ask
for it).

2.
Go to Dial
-
up Networking

in My Computer (or through Wi
ndows Explorer). Double click on ‘Make
New Connection’. The new connection wizard will be started.

3. Give a name for you new connection (e.g.
Internet on 4671355
, OR
Railnet on 3303456
, OR
Railnet on 833456
).

4. Select the modem you are using from the dro
p
-
down list (all installed modems will be listed, and only
one if you have installed only one). The properties of the modem (like for TCP/IP) can be set
differently for each connection (for example, you may want loud volume to make sure that modem
activity

is taking place, to be sure


especially on RLY phones!). Press ‘Configure’ button to set these
now. This will open a new window with following five (or less) TABs


General
,

have to use an IP address temporari
ly assigned to you by the server
-
computer (Internet server or
Railnet server).



‘Server assigned name
-
server addresses’ = on for Internet. For Railnet, you can find these out and
give them


for Railway Board Railnet server these are


Primary DNS = 10.1.2.
19; Secondary
DNS = 10.1.2.20; Primary WINS = blank (i.e. 0.0.0.0); Secondary DNS = blank (i.e. 0.0.0.0).



Use IP Header compression = on (this enables faster transmission of data from your computer to
other computers and vice
-
versa).



‘Use default gateway o
n Remote Network’ = on (a gateway is a funnel (no, not tunnel) for your
computer to direct its messages to and fro).

13.

Now you can access the NET! ENJOY!
