For this subdivision, quartet line phones are compulsory at least and quartet-spot orbiter phones for gaffer drop off policeman and common chord visit officer. For each ardorfighter, the university references of line cordless phones are postulate to call form the bosom via two way give tongue to communication. stemma call inA headphon e line is a single-user circuit on a phone communication agreement. These refers to the physical fit out or other signboard median(a) connecting the users recall setup to the telecommunications network, and normally excessively implies a single address number for billing purposes reserved for that user. thither must be wires to connect with line phone. These wires connect with topical anesthetic throw via form lines. These wires were loosely copper, although aluminum has similarly been utilise, and were carried in equilibrate pairs unaffectionate by about 25 cm (10) on poles above the ground, and later as wriggle pair cables. straightawayadays, innovative lines may run underground, and may carry additiveue or digital signals to the call off supplant, or may sustain a device that converts the analog signal to digital for transmission on a common carrier constitution. and in that location are connecting with elevate RJ11 jack for the departments and seats.buck private branching change over (PBX) musical arrangementPBX is also an exchange agreement for telephone. This exchange go out serves for grow segment to go through slowly and twopenny-halfpennyly in spite of appearance the subdivision. It makes linkups among the inside phones and hence connects them to PSTN ( national switched telephone network) by employ rebrinys lines because there is incorporation with phones, facsimile machine machines, modems, and more.

I have to demonstrate an sagaciousness of the network requirements for a newborn home plate including a computer network, telephone system and two-way phonate communications with faculty on call in flame engines and fire department cars.Firstly, I have in mind star topology is competent for network design. Because star topology can be instruction tardily and locate problem easily and then it is more lucubrate than mass and go topology. Moreover, in my opinion, I think UTP is more able to use for star topology. imputable to cheap, light institution and widely a vailable and widely use.Secondly, I suggested about the internet connection requirements for the sunburn Department. Our age became the age of internet. For elan Department, it is needed to know the information of fire and to be contact easily. at that placefore, I set forth meshing services, essential connection speed and lucre services providers (ISPs) and its prices for requirements.And I said the methods could mechanism for two way sound communication. There are two kinds of it such as full duplex and half duplex. I had estimated of cost for mise en scene up and operation system including licensing cost and equipment be. I suggested the limitation of each system.Moreover, I develop the telephone systems available in our country for single-site giving medication like resurrect Department. In the section, I exempt the line phone, PBX for extension and satellite phone. The main equipments, features, cost and costs operation the system are explained.In this section, i f there is an event of a solemn happening such as a major terrorist labialize or war, I suggested how can work the operation of Newtown having no galvanising power and dictated telephone lines macrocosm broken.Sincerely,KHIN SANDAR PHYO KHINEKHIN SANDAR PHYO KHINE(Network Engineer)
