ISDN corresponds to the abbreviations in English language for Integrated Services Digital Network, that translated the Spanish means ISDN, reason why RDSI would be brief. These abbreviations respond to the denomination of a system for the connections of digital telephones, especially created to provide services like the shipment of voice, video, as well as, digital or normal telephone lines that they arise simultaneously from the surplus of the data. This system is common some suppliers offering Internet using.
One of the advantages of this system is its considerable rapidity and high quality level if is compared it with an analogous system. System ISDN is able to reach a speed of transference of up to 128,000 bps, although in the reality, but the common thing it is that it works at a speed among 56,000 and 64,000 bps. The practical utility of knowing the speed is for example when visiting a site of Internet where video in real time is offered, and where it is common that the type of connection is asked the user on which counts, and the ISDN occurs between the options.
Approximately, it corresponds to a protocol system with which it is possible to establish connections, and also to break them, with a circuit commutator, as well as, it can grant characteristics of outpost for the calls to the clients. Through the connections whereupon it counts east system are sent signals, that they are not analogous, but digital. It is thanks to this last one that the speed of transference increases with this type of system, but besides counting on system ISDN in the central telephone office it is possible to acquire an adapted software, able to resist it, then the advantages that the user will be able to enjoy will be majors much.
As we see, the use of system ISDN is frequent in offices related to the diverse headings. For his implementation, like already it has been outlined, it is necessary to count on special equipment between which it is necessary to count on a line ISDN, as well as with a modem ISDN, those that they are used in order to send and to receive information. In their majority, the offices, use this system either counting on a local network and need to have an access to fast Internet the more, which can be obtained with router or modem of this technology; also, as we already mentioned some suppliers for homes offer this service, that can advisable as far as prices and speed.
