DSL FAQ


Q. What is Broadband Service?

Broadband is internet connectivity at high speed and without having to dial the ISP number. This results in very fast download of information from the internet as soon as you switch on your computer. (At least 10 to 20 times higher than current dial up service!)

Q. What added benefits can Broadband offer over dial-up?

It is always ”ON” the connection is always available. Unlike dial up you can simultaneously use voice and data/internet facility.It is much faster than a dial-up modem or ISDN connection. This speed substantially improves your Internet experience. You can enjoy faster and easier download of music, digital photos and software. Listen to music, watch favorite dramas, high-quality videos and play online games. It seamlessly 'shares' a phone line along with normal 'voice' services. Your phone is not engaged when you are using the Internet. You can freely use the phone at the same time as you access the Internet! No more busy signals for people trying to contact you while you surf.

Q. What affects my connection speed?

When you connect to the Internet using DSL service the speed that you will experience will vary based on a variety of factors, including the following:

  1. Distance of your telephone line from exchange
  2. Condition of telephone wiring inside and outside your location

Q. Kilobits vs kilobytes explained

In data communications, a kilobit is a thousand bits (1,000) bits. It's commonly used for measuring the amount of data that is transferred in a second between two points. Kilobits per second is usually shortened to Kbps (or kbps). For example, 53.333kbps is 53,333 bits per second. 

1 kb/s = 1000 b/s 
1 KB/s = 1024 B/s 
1 KB/s = 8.192 kb/s 
1 kb/s = .1221 KB/s 

The lowercase b usually stands for bits while the uppercase B stands for bytes. 

To find your theoretical download speed for your line, divide your advertised speed by 8.192: 
53.333kbps / 8.192 = 6.51 KB/s 

or by 10 to include overhead: 
53.333kbps / 10 = 5.33 KB/s

Q. Will I definitely get the speed that I ordered?

There is a chance that your line may only support a slower speed than you ordered due to several factors such as:

  • The length and gauge of line extended to your home or business and local telephone exchange.
  • If we can not provide the speed requested, we will contact you to determine if you want to proceed with the slower speed.

Q. How I can check my balance?

You can check you balance by visiting our Customer Billing Pages.

Dialup FAQ


Q. What's the Fastest Speed for Dial-Up?

Modern dial-up modems typically have a maximum theoretical speed of 56 kbit/s (using the V.92 protocol), although in most cases only up to 53 kbit/s is possible due to overheads. These speeds are currently considered the maximum possible; in many cases transfer speeds will be lower, averaging anywhere between 33-43 kbit/s. Factors such as phone line noise and conditions, as well as the quality of the modem itself, if the modem is external or internal, all play a large part in determining connection speeds.



^ TOP



Q. What hardware do I need to use dialup?

A modem. Most computers bought today come with 56K modems built-in.



^ TOP



Q. Why does my IP Address change every time I dial in?

Your IP address is a dynamic IP address that is given to you each time you dial up. When you disconnect, that IP address is freed. The odds of getting the same IP address two times in a row are very slim for national providers, but slightly more for local providers. Dynamic IP addressing saves IP address space so that the ISP can serve the same amount of customers with less IP addresses.

Q. Some Telco Terminology

 Bps - Bits Per Second.


Central Office - The Telco facility where your local telephone circuit leads to. Contains Switches and Trunks as well as the local telephone circuits.

DTE - Data Terminal Equipment--When using serial communications such RS-232, V.35, or X.21, the DTE is the device sending/receiving from a modem or CSU/DSU. In contrast to DCE.

Kbps - KiloBits Per Second. Measure of digital channel capacity.

POTS - Plain Old Telephone Service. Regular old-fashioned analog loop start phone service.

Repeaters, Boosters or Amplifiers - Used to "boost" (amplify) the signal when your distance from the central office exceeds 20 miles (33 kilometers).

RJ-11 - Short for Registered Jack-11, a four- or six-wire connector used primarily to connect telephone equipment.

Splitter - "Splits" the jack plug two or more ways to allow more than one device to be connected in any one jack.

Telco - Telephone Company.

Trouble ticket - A telco "work order" used to track Customer Repairs within the Telco. If you call someone "inside" the telco's repair department they will need this number to proceed. It will also be needed whenever you call to check on the status of a repair.

Q. What is the difference between a hardware modem and a software modem?

A software modem (also called Winmodem) is a modem that can connects to your PCI slot and uses operating system (Windows) to do all it's main functions. It uses your computer to process the data that the modem receives, which can slow down your downloading times and raise latency.

A hardware modem can either connect to a PCI slot or connected to your computer via serial/USB. Hardware modems have their own on-board controllers, so your computer doesn't do as much work. Hardware modems normally provide better compression of downloads and lower ping times.

Q. What is a modem?

A modem changes outgoing digital signals from a computer to analog signals that travel over telephone lines. Then changes the incoming analog signal to a digital signal your computer can understand.

Q. Why is my connection so slow?

The speed of your connection involves many different factors. Not only does it depend on the server into which you have dialed, but also on the speed of any computer from which you are receiving data. If the computer storing the web site you are visiting is slow or heavily loaded, then data transfer to your home PC will be slowed down accordingly. If you find that a site is extremely slow, try again at a less busy time or find an alternate site. If you are having trouble with all web sites being slow, there could also be a configuration problem on your computer. 

The telephone lines have a large effect on your dial-up connection -- length, load coils, resistive crosses and taps and other things that do not affect voice quality enough to require repair will adversely affect data speeds. When an analog modem connects that horrid screech/squawk noise is the two modems talking to each other testing the quality of the connection and what maximum speed they can handle over that connection.

Q. Why am I connecting at 115.2K?

If your dial-up networking (DUNS) CONNECT shows a speed of 57,600 (57.6k), 115,200 (115.2k), or 38,400 (38.4k), you are getting the port speed between your computer and modem, not the modem CONNECT rate.

With Windows 95/98/NT, a file with the .inf extension is used when you install your modem to define how Windows and Windows Programs interact with the modem.

For DUNS to report the correct speed in all cases, every possible CONNECT message must be defined in the .inf file.

Q. Checking for Phone Line Noise

To check for line noise, pick up the phone and dial 1. You should hear nothing. If you hear a noise, go to the phone box outside of your house. Connect a phone to that box and do the same test to check for noise. If there is noise, it is a problem with the phone line. In that case register a complain on 18.

If there is no noise, turn all appliances off inside. Then do the test to check for line noise. If there is no noise, turn one appliance on, check for noise, then turn on another if there is no noise. When there is noise after turning on a certain appliance, try to put that appliance away from phone lines.
