There are many telephone systems. I introduce the first PBX and KTS telephone system.

The chief equipment that would be installed.


Private Branch exchange ( PBX )

To link any internal extension to any external line.

To let internal extension to link to each other.

PBXs are more economic for larger installing.

To do an question call to another extension.

For individual and multi-office installings

Describe your demands and comparison offers of multiple traders National & A ; local concern IP PBX phone systems traders provide usage proposals for you It ‘s easy and speedy! A That ‘s it!

There ‘s no duty and no fees for this service.

PBXs make connexions among the internal telephones a private organisation – normally a concern – and besides connects with the populace telephone web ( PSTN ) via bole lines. Because they incorporate telephones, facsimile machines, modems, and more, the general term “ extension ” is used to mention to any terminal point on the subdivision.

aˆ? PBX systems are of “ cardinal system ” in that users of cardinal systems manually select their ain outgoing lines, differentiated, while PBXs select the outgoing line automatically. Hybrid systems combine characteristics of both.

aˆ? Two of import developments in the 1990s led to new types of PBXs. One was the monolithic growing of informations webs and increased public apprehension of package shift. Company needs to utilize package switched webs for informations, since it was alluring for phone calls, and the handiness of the Internet as a planetary system made package switched communications even more attractive. These factors led to the development of the VoIP telephone system. ( Technically, nil was “ exchanged ” any longer, but the acronym PBX was understood so far that it remained in usage. )

Because our system is non every bit great as these environments, KTS system is recommended for purchase. KTS is much smaller and cheaper than PBX. BusExpress is a new hotel to suit up to 50 invitees. Sun KTS system is adequate for them, even if it is less flexible option to a private subdivision exchange ( PBX ) phone.

A KTS is a multi-button, leting a company to take the right surpassing lines or incoming calls, equipped, and utilize intercom and conference installations. As the hotel offers conference suites for meetings and to keep conferences, this system is really convenient for the hotel. KTS must be installed by the user and let direction of multiple lines without the payment of a fee to the telephone company. Unlike a PBX, a user does non take to ‘9 ‘for an outgoing on-line entree.

Key Telephone System ( KTS )

Basically to supply all of the maps of a PBX.

To supply a more economic option to PBX for smaller installings.

KTS user selects external line.

Dial another line.

KTS do non hold a switchboard console

To reassign a call to another extension

To have external call

Except for call

Time prohibition of external enquiries.

Rescue last typed figure.

Maxtel is a taking name in the telecom industry trades in panbasonic epabx & A ; panasonic KTS since its origin in the twelvemonth 1992. Promoted by technocrats with huge experience in Telecom industry every bit good as in panasonic KTS & A ; panasonic epabx. Maxtel has emerged as one of the dominant market participants offering entire solutions to its clients – be it Voice or Data – applications, council chamber solutions, projectors, synergistic electronic print board, panasonic karat, panasonic epabx and multi map devices. Today Maxtel is engaged in Consulting, planing, implementing and incorporating solutions to its valued clients from “ The response to the conference room ” Offering Value-added services has been our strong suit so as to guarantee that Companies fulfill their schemes by optimising their passage into an electronically enabled concern.

The characteristics available with each system.

Dial other extensions.

To reassign a call to another extension

Name blackball

Hunt groups- One figure selects s group of lines

Name diversion- Calls sent to another extension

Short codification dialing

Night service- Handling of out-of-hours calls

Name hold- To avoid company catching

Automatic call back – Besides know as “ Call back when free ”

Conference call- A figure of telephones connected to one line

Automatic answers- Avoid holding to raise French telephone, poses a security hazard

Communication group-A section with a close community of involvement

Impermanent blackball of external calls

Save last figure dialed.

( degree Celsius ) The cost of equipment and installing


The cost of equipment is 150000kyats and installing is 200000kyats.Because this system is consist of the client like procedure. Such as

Enquiry call

External call

Name parking

Call clasp

Automatic reply, this characteristic is made like the client.

( vitamin D ) The cost of runing the system

Phone measure is 15kyats per proceedingss and I think your telephone measure is one month in 100000kyats. This is really low phone measure. And so your operator wage is 150000kyats per old ages and this salary good wage in operators groups. Ours services charges is 10000000kyats. Because our state jurisprudence. I think you would wish this phone system because system cost is low.

Supply a recommendation for this system to buy including grounds for this recommendation

I introdue the tow types of telephone system did you read. The first suggest you to purchase the KTS telephone system, because this system is little phone line and your hotel use the 50 payings invitees. Bus hotel is little hotel and this system is the best pick of your hotel. And so KTS system purchase sum is little and KTS characteristics is likely that PBX.

Because our system is non every bit great as these environments, KTS systems, the proposed purchase. Kay marked much smaller, less expensive PBX. BusExpress is a new hotel, offers adjustment up to 50 invitees. Therefore, KTS systems it is sufficient, even if it is non really flexible option to private subdivision exchange ( PBX ) telephone system.

A A Kai marked with a few buttons to straight choose the surpassing company line or call and utilize the intercom and conference installations. As the hotel conference room, and conferences, this system is really convenient to the hotel. Kay aim is to let users to put in and no demand to cover with multi-line phone company to pay an extra fee. Unlike a switch, the user need non dial ‘9 ‘to entree the mercantile establishment.

The chief equipment that would be installed


Network interconnectedness device runing at OSI web Layer 3, that can back up one or more web bed protocols and related tonss, such as TCP/IP, DecNet, XNS, SNA, OSI IP, IPX. A router can be used to associate LANs together, locally or remotely as portion of a WAN. A web built utilizing routers is frequently termed an inter-network.

Gateway Device

A wireless gateway is a computing machine networking device that routes packages from a radio LAN to another web, typically a wired WAN. Wireless gateways unite the maps of a wireless entree point, a router, and frequently provide firewall maps as good ; therefore they are converged devices.

We find the two types of web system. Fist I introduced the wimax radio networking system. And so other types of web is broadband networking.

Wireless web is really best for concern organisation, such as increased mobility, Greater flexibleness, convenience, new service chances, inexpensive and rapid installing, and scalability.

But this system is some bad grounds rule. The original on informations rates were excessively slow to function mainstream users on shared local country web ( Lan ) , and the cost of wireless solutions remained high.

The chief equipment that would be installed

WiMAX engineering, based on IEEE 802.16 criterions to turn to this convergence, supplying wireless broadband entree, “ the route ” , and holds the possible to show in a new epoch of smart phones to link the desktop extended to the shirt pocket.For general desktop broadband connexions, WiMAX will convey dramatic alterations, automatically connect desktop or notebook computing machine to the nearest WiMAX station, no affair where.

The being of the WiMAX, is a sort of inevitableness. Ordinary phone advanced states is about as smart phones, and in the instance of the UMPC ( extremist nomadic Personal computer ) , a to the full functional pocket computing machine. Computer-savvy users, these smart phones are frequently really technically oriented and are frequently heavy users of broadband Internet, so when they use their smart phones to entree electronic mail, corporate intranet, or their favourite sites, they will non run into in narrow-band speed.

WiMAX engineering for metropolitan country webs, radio broadband is a standard to supply up to 30 stat mis of fixed-station and Mobile station up to 10 stat mis, the coverage more than any other wireless criterion. In fact there are several alterations in the criterions, to supply fixed, portable and nomadic connectivity.? ‡ a‡† issues involved in the intervention, it is more common, such as radio Mobile criterions, and set uping a web for better bandwidth use.

Embedded WiMAX service besides represents a new telecom. WiMAX french friess embedded digital camera, for illustration, can put the foundation for a service, will automatically upload digital exposure to the exposure printing service. Implanting WiMAX into consumer electronics merchandises, traditionally do non hold a communicating constituent is still a long manner to travel in the WiMAX universe, but it is still an exciting chance is likely to revolutionise the manner communicating consequences.


One drawback is the cost of client equipment. On the WiMAX subscriber equipment is expected to be in the scope from 200 to 300 kwais, far transcending the cost of standard overseas telegram modem. Finally, with all the engineering, widely accepted client device will drive the cost down, but in the interim, this obstruction for operators. Some solutions might include subsidies for equipment operators, or makers of notebook computing machines and other edifice WiMAX enabled devices straight to WiMAX equipment in the equipment itself.

( 2 ) map can be provided for each system

WiMAX is a wireless broadband solution provides a rich set of characteristics and flexibleness of deployment options in many facets and potency of service merchandises. Some of the more outstanding characteristics, is deserving stressing the followers:

Two types of services:

WiMAX can supply two signifiers of wireless service:

aˆ? Non-line of sight: Service is a WiFi-like services. Here a little aerial on your computing machine is connected to a WiMAX tower. In this manner, WiMAX uses a lower frequence scope of – 2 GHz to 11 GHz ( similar to the radio ) .

aˆ? Line of sight: Service, where a fixed dish aerial points directly in the WiMAX tower from a rooftop or pole. The line is aimed at linking more powerful, more stable, so it can convey big sums of informations with fewer mistakes. Line of sight transmittal utilizing high frequence scope may make 66 GHz.

OFDM based physical bed:

WiMAX physical bed ( PHY ) , is based on extraneous frequence division multiplexing, a strategy to supply a good anti-multipath, and allows WiMAX to run under conditions of non line of sight.

More typical, utilizing 10MHz spectrum runing utilizing TDD strategy to 3:1 downlink to uplink ratio of peak physical bed informations rates of about 25Mbps in the uplink and downlink and 6.7Mbps, severally.

Scalable bandwidth and information rate support:

WiMAX engineering has a scalable physical bed construction, leting informations rates can easy scale with the bing channel bandwidth.

For illustration, WiMAX systems can utilize the 128,512, or 1048 of the FFT ( fast Fourier transform ) of whether the channel bandwidth is 1.25MHz, 5MHz, or 10MHz severally. This may be done dynamically rapid climb, support for rolling users on different webs may hold different bandwidth allotment.

Powerful security:

WiMAX supports strong encoding, advanced encoding criterion ( AES ) , and strong privateness and Key Management Protocol.

IP-based architecture:

WiMAX Forum defined a mention web architecture is based on all IP platform. All end-to-end services through IP protocol architecture trusting on IP-based end-to-end conveyance, QoS, session direction, security and mobility.

( 3 ) Equipment and installing costs

One drawback is the cost of client equipment. On the WiMAX subscriber equipment is expected to be in the scope from 200 to 300 kwais, far transcending the cost of standard overseas telegram modem. Finally, with all the engineering, widely accepted to force down the cost of client equipment, but in the interim, it constitutes a barrier for operators. Some solutions may include the e®?a¤‡ operator subsidies, or the maker of notebook computing machines and other equipment a»?e®? WiMAX WiMAX equipment straight on the devices themselves.

Here ‘s equipment. I want to utilize the equipment to 5.8 GHz, because the longest distance in the frequence. Equally far as I know, believing to acquire a wireless frequence analysis is a great thought, but the cost is 3,000 dollars, and I am non the sort of budget. In add-on, I think I can utilize the value of 2000 U.S. dollars of equipment to the existent trial.

( 4 ) system runing costs

( 6 ) bandwidth-related issues

Bandwidth and scope of WiMAX make it suited for the undermentioned possible applications:

aˆ? portable nomadic broadband connexions to supply the metropolis and state through a assortment of devices.

aˆ? to supply a wireless option to overseas telegram and DSL for “ last stat mi ” broadband entree.

aˆ? to supply informations, telecommunications ( VoIP ) and IPTV services ( ternary drama ) .

aˆ? supply a beginning of Internet connectivity as portion of concern continuity programs.

Companies are deploying nomadic WiMAX to supply broadband or place broadband connexion in the full metropolis or state. In many instances, this led to competition in the market normally merely hold entree to the officeholder through bing broadband DSL ( or similar ) operator.

In add-on, given the comparatively low cost of deployment of WiMAX webs ( with GSM Xiangbi, DSL or fibre ) , which now provide broadband to a?°?-? Ke Yi may non be feasible economic Shang.

( A ) The chief equipment for radio broadband

Web has become so rich multimedia content, ISP and WISP webs are flooded everyplace turning demand for bandwidth. Whether your deployment country – whether urban, suburban or rural countries – broadband radio Internet entree ( British West Indies ) solutions and radio backhaul for enlargement is the most cost-efficient and most efficient manner to accomplish the best possible client. Point-to-point fixed radio equipment so that any ISP or WISP Trango rapid and easy deployment of broadband entree webs in a broad geographical country for the astonishing low monetary values and first-class return on investing ( ROI ) . Trango radio ISP backhaul mandate solutions include disconnected construction of microwave wireless links, TrangoLINK Gigabit, and all out-of-door microwave wireless links, TrangoLINK vertex, which provides up to 750 Mbps and working at a distance of up to 40 stat mis. Trango features free radio ISP backhaul licensing solution is extremely cost-efficient TrangoLINK – 45 a„? Wireless Ethernet Bridge, provides up to 45 Mbps of available bandwidth every bit high as 45 stat mis. Most WISP ‘s web utilizing wireless devices work in the license-free spectrum to supply “ last stat mi ” entree for their clients, such as Trango reference 900 MHz M900S, 2.4 GHz the M2400S, and 5 GHz Access5830. With the right equipment, radio ISP can bask fast return on investing, and supply clients with dependable, always-on, high-velocity radio entree.

( C ) Equipment and installing costs

The same characteristic is a well-functioning DSSS for the U.S. military, can work to the advantage of WISP ‘s. Spectrum is inherently dependable, efficient and safe. ISP can pass more clip to acquire more clients and less clip care or fix of the web.

aˆ? Manageability – In Access5830 purposes to supply Internet service suppliers complete control of its radio web. Trango wireless all the comprehensive direction interface, including telnet, HTTP and SNMP-built wireless.

Supply a recommendation for which system to buy, including the grounds for this recommendation.

I recommend the Wi-Fi system. Wi-Fi to let the deployment of local country web ( LAN ) client devices without wires, normally cut down the cost of web deployment and enlargement. Space in the overseas telegram can non run, such as out-of-door countries and historical edifices, can suit the radio LAN. The monetary value of chipsets Wi-Fi go oning diminution, doing the web options, including the economic system, and even more equipment. Wi-Fi has become a common endeavor substructure.

The Wi-Fi in more than 220,000 people worldwide and 10s of 1000s of hot spots, 1000000s of households and concerns, college campuses around the universe. The current version of Wi-Fi Protected Access encoding ( WPA2 ) , the 2010 is considered as safe, every bit long as users use strong watchwords. The new understanding on quality of service ( WMM ) for doing the Wi-Fi is more suited for latency sensitive applications ( such as voice and picture ) ; and power salvaging mechanisms ( World Movement of Mothers power ) to better battery operation.

Comparison between WiMAX and confusion, and Wi-Fi frequent, since both are related to wireless connectivity and Internet entree.

aˆ? WiMAX is a long-range system, covering several kilometres, which uses licensed or unaccredited spectrum to supply connectivity to the web, in most instances, the Internet.

Entree to electronic mail

The biggest security menace to any email storage system is the possible for mail informations to be lost. Most organisations see this menace as bing in the datacenter and pass many 1000000s of lbs on procuring it. In fact, the menace is most likely to come from lost or stolen hardware, such as laptops incorporating offline electronic mail files. Supplying a managed method of file awaying and commanding this information is hence indispensable.

A big hazard to e-mail informations within the endeavor is improper entree to extremely sensitive letter box information. Without a method to both secure and audit this entree, there can be no warrant that information is in fact secured.

Using the radio web for the transmittal of sensitive concern information

The major concern of users at Wi-Fi hot spots, beyond non being able to link, is security. These types of radio webs are inherently “ unsecure. ” This is because encoding methods such as WEP and WPA, which are normally used to protect private radio webs, are n’t implemented due to the complexnesss of back uping users. Furthermore, utilizing WEP or WPA means you ‘ll hold to publicize the “ private ” encoding key ( s ) . This kills the whole thought of utilizing encoding, because radio eavesdroppers so have the key ( s ) to rapidly decrypt the Wi-Fi hot spot traffic.

Many Wi-Fi hot spot users do n’t understand the issues related to utilizing public radio webs, and so they do n’t take any stairss to guarantee their personal paperss, privateness and individuality are safe. The same goes with the people put ining the hot spots. They may non be cognizant of the issues they face, or the fact that they can take a few stairss to assist procure user entree.

After more than a twelvemonth of implementing my ain steps, I think it ‘s clip to assist raise consciousness of email security. And in making so, document the manner I use SSH to procure electronic mail when I ‘m on a radio web. If you ‘re concerned about aliens holding unfastened entree to your usernames and watchwords, and all the electronic mail you send and receive while connected to a public radio web – whether you use a Mac or non – you ‘ll desire to read this.

The bulk of these wireless webs are configured with the lowest possible security scenes, so that clients can link to the web as easy and trouble-free as possible. This allows merely about anyone with a wireless-capable laptop computing machine to walk into a coffeehouse, catch a cup of java, and get down browse or look intoing their electronic mail instantly.

Information is going to and from your computing machine in the signifier of little packages. Each clip your computing machine receives those packages, it reassembles them, and displays the electronic mail you received, or the web page you ‘re seeking to see. Utilities called package sniffers can observe or “ sniff ” these packages of information winging about on the web, roll uping it for analysis.

Recommendations to the security steps

Note that there are two primary security issues:

Access – devising certain that merely authorised people can utilize the radio web. Without proper entree control anyone in the locality of the edifice can utilize the radio web, and therefore acquire entree to RUnet.

Privacy – devising certain that no 1 can watch your communications. Without this, anyone any the locality of the edifice can watch everything you do on a radio web. This will allow them steal your watchwords and look at everything you are making.

You will necessitate to follow solutions that cover both of these issues. Some of the attacks address merely one, other reference both. As a speedy sum-up, there are two attacks normally used:

By and large little installings use the first attack with WPA in “ personal ” manner, and larger 1s the 2nd attack. Another possible attack for larger installings would be to utilize WPA in “ endeavor ” manner.
