DSL is Faster: ISDN provides two voice/data channels, each at speeds of 64 Kbps, while DSL is predominantly a data service providing up to 1.5 Mbps downstream and up to 512 kbps upstream. Business DSL offers T1-like speeds of up to 1.5 Mbps-more than 10 times faster than ISDN! DSL is "always on": ISDN is a dial-up service (like a regular telephone line) that's digital and carries both data and voice; Business DSL is "always connected"

A modem converts your computers data packets into an analogue signal (sounds a bit like a fax machine) and uses the normal telephone network to pass this to your ISP (Internet Service Provider) who then turns the signal back into data and thus enabling your computer to communicate on the Internet. ISDN also uses the telephone network to transmit data to the ISP but does not convert the data to analogue signals; instead it uses digital equipment at the exchange and on your computer.

When considering an ISDN or DSL line, know the pros and cons. Cost: ISDN through the telephone company costs an average of $60 / mo., plus a connection fee, and DSL is usually about $45 / mo. Sometimes connection fees are discounted when signing a one year term agreement (check with your provider). With ISDN, you should get 2 to 3 times faster downloads, and DSL is generally 10 - 20 times faster than dial up.

The most important difference is that we offer and guarantee your high-speed Internet access all the time at a price that is affordable. Most other services do not. In fact, it's right there in our contract agreement. While DSL (digital subscriber lines) and ISDN (integrated services digital network) connections transmit information over telephone lines at rates ranging from 32 Kbps, 128 Kbps, and much faster, these speeds are not provided to customers 24 hours a day.

That all depends upon the telephone companies offering both services. The two services are not the same -- ISDN provides two voice channels or a 128 Kbps data channel while DSL is predominantly a data pipe providing an asymmetrical bandwidth of up to 8 Mbps downstream and 1 Mbps upstream under good conditions. However, an DSL access network will be an overlay network and therefore will not require the expensive and time-consuming switch upgrades that held ISDN back for so long.

No. DSL and Wireless services give you greater "bang for the buck", and come in speeds up to 3.0M, but you may not be able to get DSL or Wireless at your location. We recommend ISDN for locations where DSL and Wireless are not available and T-1 is not needed or affordable.

DSL is even faster than ISDN. And DSL sends data and voice over the same line so you talk on the phone while you connect to the Internet.

Your ISDN line will not support both DSL and ISDN; this means that you must have one set of wires for each service. If you want to drop ISDN service in favour of DSL you can use the wires that were installed for the ISDN line. DSL needs a few important hardware items for it to correctly work. In order to separate your voice transmissions from data over the copper line you will need to install a simple and small splitter (available from us for $ 95.00).

option is now available in the order process to migrate your ISDN line to a normal phone line, if your line is DSL suitable. Something to consider is that your ISDN line will normally have two phone numbers and two lines attached to it. When downgraded, the second line and number will be lost ? make sure you check this out fully before ordering as it cannot be readily reversed. As there is an extra step or two involved, ISDN line to DSL orders may take slightly longer.

DSL will be the cause of ISDN's demise for several reasons: - ISDN is only available in two speeds: 64 Kbps and 128 Kbps, both of which are significantly slower than most DSL connections. - ISDN sometimes offers dedicated, always on access but not always. Furthermore, ISDN is subject to additional per-minutes fees in many locations. ISDN fees can easily be in the hundreds of dollars on a monthly basis. -ISP's will charge between $30-150 a month to provide Internet access to ISDN customers.

These are two completely different services. DSL is a dedicated connection usually to an Internet service provider (ISP) while ISDN is by definition switched. An example of when ISDN would be appropriate would be for video conferencing to different locations at different times. Another example would be if the addition phone line is more valuable to your or your business than only intermittent use of the higher speeds. TOP Your computer will connect to the DSL modem via Ethernet.

Yes. If the service is available in your area, you can cancel the ISDN line and use the same wire for DSL.

Our service is up to eight times faster than 256K DSL and nearly twice as fast as most cable. DSL and cable modem upload speeds can be much slower (128-384Kbps) than the download speeds (512Kbps-4Mbps). With our service your download and upload speeds are the same. For example, if you subscribe to our Residental Plus service you get a Asymmetrical, 384/512Kbps sustained service - download and upload, with downloads bursting to between 3Mbps and 7Mbps and uploads up to 1.5Mbps.

ISDN BRI provides the transmission of digital information between Allstream's local central office equipment and comparable equipment at the customer's location enabling simultaneous transfer of voice, data, video and fax communications at speeds up to 128Kbps (2 x 64Kbps). ISDN PRI provides two-way connectivity between a customer's Private Branch Exchange and the Public Switched Telephone Network (PSTN) over a DS-1 interface enabling customers to carry both voice and data communications.

A3. ISDN Stands for Integrated Services Digital Network, which just means that it is a digital connection between you and the local exchange. The services refer to such things as Caller ID Display DDI numbers etc. Although analogue lines at home can display the Caller's number this is not common with business telephone systems. ISDN2e lines cost ?93 per quarter to rent but they have 2 channels (2 calls at the same time). Analogue lines only allow 1 call at a time and cost ?41.

Diginet is not the same as ISDN, Diginet is a permanent connection whereas ISDN is a switched service – in other words you need to dial-up to access the service. The costs involved for a Diginet connection is a fixed monthly rental,while with ISDN there is a fixed monthly rental and an additional usage charge.

A ISDN stands for Integrated Services Digital Networks. It is an all-digital, circut-switched telephony system that is an alternative to analog modems, although both can operate over regular copper telephone lines. What this means for you is faster, more reliable connections. ISDN comes in two different speeds, 64k and 128k. Many of the problems that exist with normal analog modems which operate over POTS (Plain Old Telephone System) do not exist with ISDN.

Yes, cable, DSL, ISDN, and T-1 lines will all work with MyOrderDesk. So will plain old modems. In other words, anyone with an e-mail account who can surf the Web with a browser can use MyOrderDesk. Back to Top Learn More..
