Private Branch Exchanges and PBX Installers
For many years, numerous citizens have searched for various ways of providing solutions to typical modern problems. Furthermore, commerce and business has benefited greatly from the numerous technological and scientific advancements and inventions created throughout the years. With this in mind, recent international economical decline has led to more and more companies, small businesses and corporations choosing to hire PBX installers to install a more effective phone system.
A PBX or “Private Branch Exchange” system is a private telephone network, usually used within an organization or company. Telephone users can share various outside telephone lines for outside usage while internal telephone lines are used for inter-company communication. This type of system also connects to “Public Switched Telephone Network” or PSTN. Recent technological advancements has successfully merged PBX and VoIP.
This merging has formed “IP PBX”. IP PBX effectively uses internet protocols to transmit phone calls. In addition, it is based upon software, making it more cost-effective and economical. Currently, four types are available for selection and usage, including hosted, traditional, hosted IP and IP. Each one was created to cater to specified organizational needs.
Though most organizations fully understand the necessity for this complex system, most lack the understand of how to obtain proper services, equipment and installation. Similar to internet and other network services, thousands of technically skilled installers are available to provide these services. One can go about obtaining them through various ways.

After determining the needs of the company, users will be able to secure the best type of installation for their business.
In addition, users must determine if they will be needing a multi-location or single location installation. For companies restricted to one physical location and one telephone server, single location set-up would be best. Companies having multiple telephone servers and or various locations, would greatly benefit from the multi-location set-up install option.
Various companies have stated that the complexity of securing the best installer or contractor increased hindered their ability to find the best suitable installation service.

Brief History Of The PBX (Private Branch Exchange)
All but the smallest businesses demand more capabilities from their telephone service than those provided to consumers. They need many telephone lines coming in and going out. They have to be able to control which telephone receives an incoming call. These requirements motivated telephone companies to design telephone switching equipment that could be installed at the user’s location. This equipment is referred to as a PBX (Private Branch Exchange).
The original purpose of the PBX was to make it possible for businesses to control the routing of incoming phone calls. This capability is needed when many incoming calls may need to be handled by many different employees. The telephony technology of the time could only support this by taking the control functions that were normally performed by the telephone company central office and duplicating them at the business location.
It is important to remember that current phone technology is much more advanced than it was when the first PBXs were designed. These PBXs used the same basic equipment that was installed in the phone company’s switching centers. If today’s technology had been available then, a different solution might have been chosen.
Recently there has been a widespread recognition that user companies are generally not the best managers of their telephone equipment. Talented experts at the phone companies or third party vendors are often better equipped for this job, and these days they are frequently given it via outsourcing. Smaller companies have rarely tried to do this themselves.
The Centrex type of service use a different approach. These products provide services similar to those of a PBX using central office control and switching equipment. These are not new. Outsourcing has tended to increase the usage of this kind of product.
VoIP (voice over Internet protocol) technology has partially moved the flow of data for voice calls onto the Internet. This change has not removed the need for advanced call routing, though it may change where it is done. PBX facilities will continue to be very important for almost all organizations.

The Concept Of DID (Direct Inward Dialing)
Since the time of analog telephony, there has been an economic and technological need to have a means serve multiple customers with limited infrastructure. The DID (Direct Inward Dialing) addresses this requirement very well. It is no surprise that even today this idea is relevant despite all the technological advancements.
The original telephony concept associated dedicated resource to each customer. This meant that every telephone number had a dedicated line from the central office to the customer premise. Thus, any organisation looking to get telephone connection for a set of its employees had to purchase equivalent number of individual lines.
With the advent of the Direct Inward Dialing concept, the need for such individual lines was eliminated. Multiple numbers could not be serviced over a single trunk connecting the enterprise PBX to the central office. In the analog telephony system, there used to be operators that would complete the connections. DID concept eliminated the need for such operators too.
This concept was an economically viable alternative for the customer as well as the service provider. For the customer, this service cost a lot less as compared to getting individual lines. For the service provider this meant that the same infrastructure could be used for multiple telephone numbers.
This concept was so effective that even after the inception of digital telephony, DIDs were in demand. Instead of analog trunks, the numbers were now serviced over ISDN links between the PBX and the central office. In fact, till date many enterprise customers subscribe to PRI services to get DID numbers.
The latest innovation in voice telephony is the VoIP. Even here this concept is relevant and is implemented over the trunk between the central office switch and the communication gateway. The dedicated numbers to the gateway are assigned to individual VoIP phones within the organisation.
DS3 Bandwidth Explained In Simple Terms
With a large percentage of homes now having a DSL (Digital Subscriber Line) installed for E-mail and Internet access, many people now have more of an idea of what bandwidth is all about. Explaining DS3 Bandwidth then, should be generally understood.
Formerly, the classifications for digital circuits were denoted by the terms T1, T2 and T3 which referred to the signal processing equipment. The modern equivalents of the old classification, namely DS1, DS2 and DS3 are exactly the same circuits but now refer to the format and the rate of the signal. DS stands for Digital Signal and DS3 is equivalent to the T3 circuit.
The full DS3 line operates at 45 Mbps or about 90 times the speed of a standard DSL circuit commonly used in today’s households. This equates to 90 people accessing the Internet, or another application, all at the same time and getting the same response as a single DSL user at home. DS3 is rated in excess of twenty times the speed of a normal T1 circuit making it ideal for companies needing the high speed transfer of data between head office and branch offices.
If the full DS3 speed is not required, a fractional DS3 circuit is available, which, though not as fast is also considerably less expensive. Another option, the burstable DS3, allows use of the circuit at a slower speed during the day with periods of full speed access at times agreed to by the user and service provider.
Full-motion video in real-time and extremely large databases may be carried over a DS3 line on a very active network. High-volume traffic, such as that experienced by large companies and universities, is carried with ease over this type of line. Alternative users are typically those supplying PBX and VoIP systems and large call centres. Added to this are companies that offer video conferencing and software development not to mention research laboratories which are also high speed data users.
There are normally two monthly charges associated with these lines. One charge applies to the local loop which is for that portion of the line from the local exchange to the clients premises. The other charge is for network access through a port on the carriers equipment. The charge for the local loop may vary depending on the distance from the user to the exchange.
DS3 Bandwidth speeds are made possible by combining the signals of 28 DS1 circuits which are multiplexed into 7 DS2 circuits. These are again fed through the multiplexer and emerge as one DS3 line. The line can transport the equivalent amount of data as 672 telephone lines.
