The accelerated growth of content-rich applications that demand high bandwidth has changed the nature of information networks. High-speed communication is now an ordinary requirement throughout business, government, academic, and work-at-home environments. High-speed Internet access, telecommuting, and remote LAN access are three services that network access providers clearly must offer. These rapidly growing applications are placing a new level of demand on the telephone infrastructure, in particular, the local loop portion of ....etc

Asymmetrical Digital Subscriber Line

1.Links subscriber and internet service provider only for residential users.

2.Uses existing local loops.

3.Uses currently installed twisted pair cable.

4.Can carry broader spectrum of 1MHz or more.

ADSL CONFIGURATION

The twisted pair local loop is actually capable of handling bandwidths up to 1.1Mhz, but the filter installed at the end office of the telephone company where each local loop terminates limits the bandwidth to 4Khz(for voice comm.). If the filter is removed the entire 1.1Mhz i ....etc

ADSL technology is asymmetric. It allows more bandwidth downstream -from an NSP s central office to customer site - than upstream from the subscriber to the central office. This asymmetry, companied with always-on access (which eliminates call setup), makes ADSL ideal for Internet/intranet surfing, video- on -demand, and remote LAN access. Uses of this application typically download much more information than they send. ADSL transmits more than 6 Mbps to a subscriber, and as much as 640Kbps more in both directions. Such rate expands existing ac ....etc

The circuit presented here can beused for connecting two telephones in parallel and also as a2-line intercom.Usually a single telephone is connectedto a telephone line. If another telephoneis required at some distance, a parallelline is taken for connecting the othertelephone. In this simple parallel line operation,the main problem is loss of privacybesides interference from the otherphone. This problem is obviated in thecircuit presented here.Under normal condition, two telephones(telephone 1 and 2) can be usedas intercom while tel ....etc
