Chapter-2 Exchanges Exchange are those from were we can transmit our data or voice from one end sender to other end receiver. All telephone subscribers are sere by automatic exchange today’s automatic exchange use a pair of computer one running that program that provides the services.
Typical exchange consists of:- 1 . Switch room 2. Operation and maintains room 3. Input output processor room 4. Power plant room 5. Battery room 6. Main distribution frame room In BOSS Lithuania, many types of exchanges working which are as follow:- . Automatic exchanges 2. Digital exchanges 3. Trunk automatic exchanges 4. COB 283 exchanges 5. COOT exchange 6. AXE 10 7. EBB 8. SEES 9. SEWED 1 . Automatic exchange: Automatic exchanges, or dial service, came into existence in the early 1 9005. Their purpose was to eliminate the need for human telephone operators.
Before the exchanges became automated, operators had to complete the connections required for a telephone call. Almost everywhere, operators have been replaced by computerized exchanges. Telephone switch is the brains of an automatic exchange. It is a device for routing calls from one telephone to another, generally as part of the public switched telephone network. The local exchange automatically senses an off hook (tip) telephone condition, provides dial to that phone, receives the pulses or TDMA tones generated by the phone, and then completes a connection to the called phone within the same exchange or to another distant exchange. . Digital exchange:- Digital switches work by connecting two or more digital circuits together, according to a dialed telephone number. Calls are set up between switches using the Signaling System 7 protocols, or one of its variants. In U. S. And military telecommunication, digital switch is a switch that performs time vision switching of digitized signals. This was first done in a few small and little used systems. The first product using a digital switch system was made by Oatmeal. Prominent examples include ITT System 12, Nortek DMS-DID, Lucent SEES switch, Siemens SEWED and Ericson AXE telephone exchange.
With few exceptions, such as PAM switches, most switches built since the sass are digital. This article describes digital switches, including algorithms and equipment. Digital switches encode the speech going on, in 8000 time slices per second. At each time slice, a digital PC representation of the tone s made. The digits are then sent to the receiving end of the line, where the reverse process occurs, to produce the sound for the receiving phone. In other words, when you use a telephone, you are generally having your voice “encoded” and then reconstructed for the person on the other end.
Your voice is delayed in the process by a small fraction of one second -? it is not “live”, it is reconstructed -? delayed only minutely. 3. Trunk automatic exchanges: Tandems help connect pairs of switches that are not directly connected. Inter- city switches are called trunk automatic exchanges (TAX). For example, a TAX in Lithuania with a connection to a switch in Embalm, would indirectly connect all the switches in Lithuania (connected to this tandem) to Embalm. All of these tandems have trunk connected to the local VASS international tandem switch, called the gateway Digital Switch. . COB 283 exchange: COB stands for the Origin Control Version 283 version. This exchange is in used these days. This is also a digital switching system. This exchange works at 5-25 degree census. A maximum of 2048 PC switch can be conducted. This exchange support both analog and digital subscribers. . COOT exchange:- C-DOT triggered a telecoms revolution in the rural India that was responsible for all-round socio-economic development. Rural India gained access to a whole new world of opportunities as they got connected globally.
As part of its development process, C-DOT has spawned a wide base Of equipment manufacturers and component vendors for the industry. C-DOT exchanges can be configured using four basic modules:- 1. Base Module 2. Central Module 3. Administrative Module 4. Input Output Module 6. AXE 10:- The AXE telephone exchange is a product line of circuit witched digital telephone exchanges manufactured by Ericson, a Swedish telecoms company. It was developed in 1974 by Element, a research and development subsidiary of Ericson and Telemarketer.
The first system was deployed in 1976. AXE is an acronym for Automatic Cross-Connection Equipment. Ericson AXE telephone exchanges support lawful intercepts via the remote-control equipment subsystem (REST), which carries out the tap, and the interception management system (AIMS), software used for initiating the tap, which adds the tap to the REST database. In a fully operating lawful interception system the REST and AIMS both create logs of all numbers being tapped So that system administrators can perform audits to find unauthorized taps.
