ADSL/T-DSL<br />

– For rapid Internet access<br />

Every Telekom customer can get ADSL, irrespective of whether the connection is<br />

analog or ISDN.<br />

The existing telephone set-up is not changed.<br />

The analog connection carries an additional data signal alongside the telephone signal.<br />

Calls can still be received, even when on line.<br />

Where ISDN is combined with ADSL/T-DSL, telephone calls, fax messaging and Internet<br />

surfing can be conducted simultaneously.<br />

Two additional devices are needed to use ADSL / T-DSL:<br />

- An ADSL / T-DSL splitter and an ADSL / T-DSL modem.<br />

The splitter separates the ADSL / T-DSL signals from the normal telephone signals.<br />

Pay particular attention that the splitter is fitted in front of the terminal device.<br />

The modem provides high-speed access to the Internet.<br />

US / Western<br />

This technology, normally called US, or Western Technology, is mainly to be found in<br />

the USA and the United Kingdom. Bearing in mind the ISDN connection technology,<br />

(Integrated Services Digital Network) this technology will be of increasing significance<br />

in Germany as well. Depending on intended use, we distinguish in this case between<br />

4 pin (telephone), 6 pin or 8 pin (accessory equipment) connection sockets or plugs.<br />

TAE<br />

As a new method of installation on the public telephone network, German firms,<br />

working on behalf of the Bundespost (German Post Office), have developed the<br />

Telecommunications Connection Units (Telekommunikations Anschluss Einheiten<br />

(TAE)). They are interface connectors for the connection of telephone equipment or<br />

accessories in different areas. In the long term, TAE will replace the previously<br />

common methods of connection (VDo, ADo). They conform to DIN 41715.<br />

Due to system modularity, compact sockets for the 2-way and 3-way plug connectors<br />

are also available. The plug system is based on a 6 pin basic configuration. They will<br />

be divided into F codification (for telephone equipment) and N codification (for<br />

non-telephone equipment, like answering machines, telex or data transfer equipment).<br />

This will ensure that there will be no confusion of plugs.<br />

What does ADSL mean?<br />

- Asymmetric Digital Subscriber Line<br />

- High-speed access to the World Wide Web<br />

- Applications that are not possible with<br />

analog modems or ISDN.<br />

- Page creation in seconds<br />

- Downloading in record time<br />

- Superb quality film and music videos<br />

Data rates ADSL / T-DSL:<br />

Downloads = ADSL / T-DSL 768 kbit/s<br />

12 x faster than ISDN<br />

30 faster than an analog<br />

modem<br />

Uploads = ADSL / T-DSL 128 kbit/s<br />

Downloads im comparison:<br />

768 kbit/s = ADSL /T-DSL<br />

64 kbit/s = ISDN<br />

28,8 kbit/s = analog modem<br />
