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.

A A second existing voice grade line for a fax machine, modem, or children's line is an excellent choice to convert to an ISDN line. The existing phone number can even be transferred to one of the ISDN line B channels. However, the primary phone line should still remain an ordinary analog voice line. This is because the standard telephone service provided by POTS ports on terminal adapters are dependent upon the terminal adapter itself.

Yes, it is possible to get DSL without an existing phone line. In order to have an activate DSL connection online you will have to use our DRY DSL service. Your residential address will be required to determine how far your home is from the Central Office (CO). The Band rate required from the Central Office to your home is determined by the distance from the Central Office (CO). DRY DSL is for residential and business locations with no active phone lines (no telephone number).

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.

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.

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.

In many cases you can convert an existing telephone line to a DSL line. In this case the POTS phone number and billing would remain the same and any existing special services on the line would also remain unchanged (like call-waiting, message center, etc.). In some case, a new line has to be installed because of load coils or other DSL-unfriendly devices.

Also known as Broadband, an ADSL (Asymmetric Digital Subscriber Loop) line is a form of Digital Subscriber Line in which the bandwidth available for downstream connection is significantly larger than for upstream. Although designed to minimise the effect of crosstalk between the upstream and downstream channels this setup is well suited for web browsing and client-server applications as well as for some emerging applications such as video on demand.

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

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.

In almost all cases, ISDN requires special equipment. If connecting ISDN to a PC, a terminal adapter (sometimes called an "ISDN modem") is required. Many of the terminal adapters come with 1 or 2 standard jacks (RJ-11), so standard (analog) phones and/or facsimile machines can be connected. BellSouth has now made it easier than ever for you to purchase ISDN equipment by forming alliances with ISDN equipment manufactures and distributors.

We have ISDN connectivity available through the dialup service. An ISDN line is just like an external phone line and is not part of the campus network. You need to contact the Telecoms Team who will discuss your needs and arrange for installation.

While this is a matter of choice, an ISDN line can serve as the only phone line to your home and business -- if you have a backup power supply (as mentioned above) in the event of a power failure. You may want to keep your existing lines and add ISDN for specific purposes that cannot be accommodated by your present line (e.g., higher transmission speed).
