A Brief Introduction To Long Distance Communications Services

Hillary Cyril | Editor, TechAnnouncer




Long-distance Communications refer to telephone, fax, and broadcast service over radio and wire systems between correspondents usually located at different good ( Nearly unlimited ) distances from each other, generally more than 100 miles apart. The word long-distance communication came about in the early technologies of transmission of electric signals over open-wire communications lines; a synonym is intercity telex, and antonyms are local telex. The very first long-distance calls were made by telex operators, and the beginnings of this new medium of long-distance calls were facilitated by the adoption of the telephone system which moved long-distance calls over wires that were still under the exclusive control of the local telephone company. These local telephone companies were also the original long-distance carriers and the principle of long-distance was adopted in their system.

In modern times, long-distance communications have largely replaced the use of the open wire system, and now most communication means are either wireless or via satellite. One thing that has always been a problem in long-distance communications is the fact that the service providers do not have a permanent telephone exchange point (PEEP) so that all calls are placed on different extensions. Call forwarding has been implemented to solve this problem, as now calls placed on one extension receive a destination address from the other extension. Call forwarding also transfers the call signal between the extension and the originating cell phone or other devices.

There are several different kinds of PEEP that can be used for long-distance communication; the best-known kind is the centralized long-distance telephony exchange or CLEX. This is a toll-free facility for single-line and multi-line phones that provides seamless connectivity between various telecommunications network carriers. The different carriers bring their own termination points to connect to each other and no one outside the system will have any access to the terminations. Another popular kind of PEEPs is the trunking system, which simply sets up a connection between two termination points. This allows the same number of carriers to connect, but with less security than the centralized system.


There are some other security measures that are applied for long-distance communications lines as well. There are physical controls at the carriers’ terminal sites as well as control systems that limit the amount of traffic that goes through each point at any given time. There are also some physical controls at the carrier end of the line, such as limiting the bandwidth of the network and the access of the media to the outside world. These physical controls are very effective for ensuring that security is maintained.

The availability of alternate telecommunications services means that long-distance customers can use cellular phones while they are on the road. Cell phones can transmit signals as far as the highway and satellite technology has made it possible to send signals around the globe. These services make international voice calls affordable for even the most avid travelers. International long-distance calling offers consumers an easy way to keep in touch without missing important family calls.

Long-distance telephone communications services mean staying in touch with friends and family even when you’re on the move. Many different types of carriers offer these services, so there’s a good chance that you’ll be able to find a plan that suits your needs. Some providers even offer packages that include voice mail so you get extra services in addition to your basic exchange telecommunications service.
