A
public or routeable IP address assigned by your ISP with no
more than a 30 bit subnet mask.

access
server
|
A
device with a series of modems which answer ISDN and analog
phone calls (also called a terminal server.) The equivalent
for DSL is called a DSLAM.
|

agent
|
When
you run WhistleWare, the InterJet system software, the first
page you see is the InterJet home page. The appearance of
this page varies, depending on the administrative privileges
assigned to your account. The Agent Selector in the upper-left
corner of the page allows you to select an InterJet agent.
InterJet agents help you to perform basic tasks, such as changing
your password, handling e-mail messages during your absences,
using mailing lists, and creating Web pages. If you have the
administrative privilege associated with an agent, the agent
also helps you to perform administrative tasks. If you have
neither the basic nor the administrative privilege associated
with an agent, that agent appears dimmed, with a slash mark
across it.
|
| |
analog
/ analogue
|
Analog
modems allow digital data to flow over the telephone company's
existing analog network by performing a digital to analog
conversion for transmission onto the network and vice versa
on the receiving end. The only necessity for analog modems
is that each end of the call must have a compatible modem.
This makes analog modem connections the most ubiquitous form
of data communications available today. However, analog modems
are limited by the telephone company's voice bandwidth service.
Current analog modems are struggling to achieve rates of only
56 kbit/s over those networks.
|
| |
APOP
(Authentication
Post Office Protocol)
|
An
email security mechanism that encrypts your password before
sending it over the Internet when you attempt to login to
a mail server to retrieve email messages. However, APOP does
not encrypt the body of an email message that you retrieve
over the Internet.

After
you enter the appropriate telephone number and 24-digit registration
ID, your InterJet automatically dials IBM, downloads configuration
information and configures itself.

- The
customer's ISP needs to provide to the customer a static
IP and DNS reverse service to make this compatible with
your service.
- Availability
of connectivity options and local dial-up numbers depends
on your geographical location.
- The
customer is responsible for paying the local telephone company
charges associated with your use of the WebConnections service.
These may include an installation charge (for example, if
you chooses to install a new analog or ISDN line), monthly
line fees and per-minute charges (for example, ISDN may
be charged either per-minute or at a flat rate by your local
telephone company) and other charges. If DSL is the chosen
connectivity, then Small Business WebConnections includes
the monthly DSL line charge and the installation of the
DSL line. For analog and ISDN service, we will do our best
to assign a dial-up number that is located in the customer's
area code. However, not all calls within your area code
may be classified as local calls by your phone company.
We recommend that the customer check with their phone company.
- Individual
ISP account is required. Additionally, the email client
has to support APOP or SPA.
- Silver
Basic and Gold Basic both include domain name registration
or transfer, domain name resolution, email routing, InterJet

the customer's web site. The 24x7 technical support does
not cover ISP-related support, such as connection and bandwidth
issues.

cable
modem |
Cable
modems are capable of very high speed throughput (bandwidth)
and are used when accessing the Internet across a television
cable company's network (usually fiber). However access via
cable modem from a cable company is normally structured in
a way that has a group of users sharing a 'node' in a specific
area. The more subscribers in that area, the less bandwidth
is available to each. So although the cable modem itself can
handle high throughput, the bandwidth available to a user
may be less.

DSL
|
DSL
refers to a class of technology used to obtain more bandwidth
over existing copper telephone cabling running between a customer's
premises and the telephone company's Central Office. DSL allows
simultaneous voice and high-speed data services such as super-fast
Internet access over a single pair of copper telephone wires.
This allows you to talk on the phone and browse the internet
at the same time. There are several variations of 'DSL' that
include:
ADSL
- Asymmetric Digital Subscriber Line
R-ADSL - Rate-Adaptive Digital Subscriber Line
HDSL - High Bit-Rate Digital Subscriber Line
VDSL - Very High Bit-Rate Digital Subscriber Line
SDSL - Symmetric Digital Subscriber Line
A telephone
company must make compromises between costs, distance, speeds,
reliability, equipment, etc when implementing or offering
'DSL' services. Each variation of 'DSL' reflects the different
compromises made by Telco's when deciding how far and how
fast data can flow on a particular kind of subscriber line.

firewall
|
A
firewall is a security router that sits between your network
and the outside world to prevent unauthorized access. All
network traffic into and out of the LAN must pass through
the firewall, which runs special software that prevents unauthorized
users from gaining access. For a firewall to be effective,
all traffic that flows between the two networks must pass
through it. The firewall examines the traffic and compares
it to the set of rules for which it has been configured. If
the traffic matches the rules for traffic that can be transmitted
between the networks, the firewall forwards the traffic. If
the traffic matches the rules for traffic that should be blocked,
the firewall blocks the traffic.

(File
Transfer Protocol)
|
A TCP/IP service that allows you to download files from and
upload files to an FTP server on another computer. To connect
to a remote computer to transfer files, you must supply a
login name and password. If you do not have an account on
the computer, you can use anonymous FTP to access any files
that are available to the public. Typically, your browser
of FTP client software automatically supplies the login name
anonymous and your email address as the password.

ISDN |
ISDN
is a telephone company technology that provides digital service
across existing telephone copper wiring typically in increments
of 64 Kbit/s channels. ISDN has been around for many years,
but its popularity in the USA is only now beginning to increase
as a result of limitations of analog modems and the rise of
Internet usage. Roll-out of this service by most telephone companies
in the USA has been slow due to high costs, lack of standards
and low acceptance rate by consumers. [Note: ISDN is widespread
throughout a number of other countries including Germany, France
and the UK].

web access |
The
InterJet administrator can specify the level of internet access
for each work period. These access levels apply to individual
users according to the privileges that you assign to their accounts.
For example, if you limit Internet access on non-business days,

privilege can access the Internet during that work period. You
can use the Personnel Agent to modify the privileges for specific
user accounts at any time.

POP
(Post

|
A standard mail server protocol for storing email messages
and downloading them from a mail server to a client computer.
Using POP, the mail server stores email messages until a user
logs into the server, then downloads the messages to the user’s
computer. A user can then read the messages using any mail
program that supports POP. A number indicates the version
of the protocol — for example, POP3, is the current version.

proxy
server
|
A
proxy server is a computer that maintains two network connections,
one to network A and one to network B. No network traffic
passes directly through the proxy server the way it travels
through a router. On Internet-connected networks that utilize
proxy servers, internal network users access the Internet
by running applications directly from the proxy server. For
example, internal users configure their web browsers to contact
the proxy server with their web requests. The proxy server
conducts the communication with the Internet, then transmits
the replies back to the original internal user.

called Web site mirroring, occurs automatically once a day,
at the time you specify. By default, Web site mirroring occurs
daily at 2 a.m. |
