Basic ISDN effectively converts your telephone line to digital with two 'channels', each of which can carry a telephone conversation or data at 64Mb/s. When neither phone line is in use, the data channels can be combined to give 128Mb/s, which puts it at the bottom end of "Broadband". The drawback of ISDN is its price - Telstra have considered it a premium business service, and have priced it out of the reach of residential users.

ADSL is perfect for home or small business. In any situation it will improve performance, but here are some particular uses: Firstly, ADSL is a network connection, so it does not have to be restricted down to one machine, like a modem. Plug your ADSL line into your network hub and all your machines can have access to the Internet. The age-old problem of e-mail lag is solved.

Yes! ADSL modems use digital coding techniques to squeeze up to 99% or more capacity out of a phone line without interfering with your regular phone services. That means you could be simultaneously talking on the phone or sending a fax - while surfing the World Wide Web. The two services (voice and data) operate independently of each other even though they are using the same telephone line.

You will be able to get ADSL if the local exchange supports ADSL and you order an analogue telephone service (extra charge) to be used for the ADSL service. This service would be charged a standard telephone line rental. How many IP addresses do I get with my ADSL service? You will receive at least one static IP address with your ADSL order.

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.

ADSL is not currently available for aerial phone lines. The current ADSL product launched in October 2000 has proven to be a technical challenge for aerial phone lines: Dies führte dazu, dass ADSL auf Freitleitungen seitens Swisscom unterbunden werden musste. Daraus entstand in der Vergangenheit einige Verwirrung und kontroverse Aussagen.

Yes, however the line has to be re-graded to an analogue line, and BT charge to do this, you are also liable for any terms left on the ISDN contract. Once the line has been regraded, it will be checked for suitability for ADSL. There is a chance the line is not suitable and BT will charge to convert it back to ISDN.

ADSL can’t be installed on ISDN lines, so either you need a separate new (analogue) phone line or for the ISDN to be converted back to an analogue service.

Eicon has demonstrated ADSL over ISDN operation using the G.992.2 Annex B standard. Currently shipping products do not support ADSL over ISDN. The reason is that an ADSL connection may share the standard telephone wiring, however, ADSL itself is only connected to the Internet. Since a Diva ADSL modem only accesses the ADSL connection, it too is only connected to the Internet.

ADSL offers a cheaper and faster service than ISDN. ISDN works by providing two voice channels or a 128 Kbps data channel while ADSL is predominantly a data pipe providing an asymmetrical bandwidth of up to 6 Mbps downstream and 640 kbps upstream. However, the ADSL network is an overlay network and therefore does not require the expensive and time-consuming switch upgrades that held ISDN back for so long.

You can have either a dedicated analogue line or ISDN or ADSL as required there are small monthly charges for extra lines.

Yes with some ISDN hardware - you may also need to obtain the ComISDN drivers. Please see www.nch.com.au/ivm/modems.html for more information. If you find any other single line TAPI device for ISDN that work with Dial Dictate, please Contact Us.

The two services are NOT the same. ISDN provides two voice channels or a 128 Kbps data channel while ADSL is predominantly a data pipe providing an asymmetrical bandwidth of up to 8 Mbps downstream and 1 Mbps upstream under good conditions. However, an ADSL 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.

You cannot use both WAN interfaces to connect to internet (via the same ISP or different ISP's) at the same time, as the router wouldn't know which internet connection you wanted. But you can have the ADSL connected to the Internet and use the ISDN for a dial-in teleworker or a VPN to a branch office. Technically speaking, where the ISDN is being used to route to a specific directly-dialled subnet. If you have a remote office or teleworker which only has ISDN (i.e.

Most of these services are not available in our service areas. Cable Modems, ISDN, and ADSL are all dependent on physical wires, and a middle man (i.e., the phone company). With Wireless Internet Access, you are dealing with no wires and directly with the ISP; there is no middle man. There are also speed factors. Click here to see a chart on speed comparisons.

Flat rate charging ISDN is essential if your application is video conferencing over switched PSTN numbers. ISDN also provides the ability of having 2 phone lines on the same copper loop, which is not possible with ADSL.

No, you will not be able to dial into Sltnet using SLT ADSL Express Account on a PSDN / ISDN dial-up connection. Access speed is just one of the many factors affecting the Internet throughput speed. Some other factors that will affect the speed are: The Web Surfer load, performance and the Internet connecting link speed, Sltnet Internet International Backbone shared load for ADSL users and telephone line Internet traffic all over the world.

Yes. Your ADSL socket splitter should be connected first, and then the AutoDialler should be connected to the phone port of your splitter. You should be able to use your phone line entirely independently of your ADSL data connection.
