Comparing Business Telephone Systems

So, you’re looking for a new business telephone system. Perhaps you’re setting up a new office or, perhaps, it’s time to upgrade your outdated system. Whatever the reason, it’s likely that you’ve started searching and discovered that there’s a bewildering array of choice available – various brands, different technologies and an endless list of possible features, all of which vary substantially in cost and between different providers. How are you ever supposed to decide on the right option for your business? We offer some pointers to help you compare business telephone systems and make the right choice…

Before you begin comparing phone systems…

Decide what it is that you need and this will narrow down your choices. Consider the size of your business, how you operate, your budget and likely future requirements (you don’t want to buy a system that will be no good a year or two down the line!). Consider the following points and make a list:

  • If you already own a phone system, what is it lacking?
  • How many business telephone lines, extensions and handsets do you need?
  • Which features are a must-have and are there more that are desirable?
  • Do you operate across multiple sites, including separate offices, mobile and remote workers?
  • Do you need additional software such as call management and call recording?
  • Is your business likely to grow in the next few years and, if so, how much?
  • What is your maximum budget?

Once you have made your list, you will find that the choices are reduced to a manageable number of phone systems as the others are not suitable for your needs. You can then begin deciding which of the remaining options will be the best investment for your company. At this stage, you can either approach a provider and ask them to make a recommendation or you can do some further research and decide which system is best before you go on to compare providers.

Technology

Voice technology has evolved considerably over the past few years. When comparing business telephone systems, you will notice that the technology can differ substantially between different systems. The main thing to consider is whether you want to stick with the more traditional PBX phone system that requires conventional business telephone lines, or move to the more modern VoIP technology. VoIP enables voice calls over your internet connection, instead of the traditional phone lines. Many businesses are transitioning to VoIP because the technology has many advantages over traditional phone systems, not least the ability to reduce your call costs substantially.

VoIP is a viable option for most businesses, but those located in areas that suffer from poor internet connectivity would be best to stick with a PBX system, at least for the next few years until high-speed internet connectivity is available in the area.

If you are considering a VoIP phone system, you will need to decide whether you are going to opt for an in-house or hosted phone system. A hosted VoIP phone system can bring further benefits, beyond the benefits offered by VoIP in general. A hosted system is owned and managed by the provider, which is also responsible for all ongoing support and maintenance work. This offloads the burden of technical management and can often result in increased reliability and uptime. But, you won’t actually own the equipment and will have to pay a monthly fee for the service, which is typically charged on a per-user basis. Because of this, hosted phone systems tend to work out much better value for money for small to medium businesses.

There are also some phone systems available that offer both traditional and VoIP capabilities. These are a good option for those that are not quite ready to move to full VoIP, but plan to do so in the future. Several of the NEC telephone systems, for example, offer this capability.

Features

The number of useful features available with business phone systems is constantly increasing. Having made your list, you will know which features are a must-have and might even have some idea about additional features you think your business could benefit from. There’s probably a great number of features that you’re not sure about, however. You may have heard of them, but may not be sure what they actually do. These days, there are some pretty clever phone system features that have real business enhancing potential. It’s worth doing a bit of extra research to make sure you’re clued up about the different features on offer.

Cost

It’s important to make sure that you get the most out of your budget. Make sure that your business phone system shortlist includes options that offer a reasonable level of scalability and all of the features that you need, as a bare minimum. When comparing phone systems, make sure that you also compare providers as you will notice that quotes can vary substantially. Ensure that the quote you receive is for the phone system and the cost of installation as you don’t want to encounter any hidden costs. A good provider will take the time to listen to your needs and make recommendations, or even tailor comprehensive solutions to make sure the solution you are offered is the best option for your business.

Introduction to Router Technology

The 4×4 audio video router which can route four different inputs to four different outputs with increased speed and completely eliminating the flicker from picture. In switching of audio and video signals, multiple in and multiple out is very difficult task to perform simultaneously and this can be solved by audio video router.

ROUTER means something which directs or forwards information on a specified route. Router is mainly used for routing the signal from input to the output, in the CATV system and CCTV system. The routers, which have both Audio and Video signals as input are said to be audio video router and Audio video router (AVR) routes different audio-video inputs to different outputs.

In router, the FRONT PANEL is provided for input and output selection while the BACK PANEL is provided for the connection of Audio and Video input and to carry out Audio and VIDEO output separately. I Study journal for knowledge whose characteristics is International Journal for engineering, International Journal for Technology and international journals with impact factor.

We know that human persistence of eye is 1/16th of second and using audio video router the switching of video will be done in 0.01microsecond which is greater than persistence of eye. Therefore, frame repetition rate of picture will be very high and picture will move very fast and we see smooth picture running on the screen. Therefore flicker will be completely eliminated from the picture. Here we use different programming logic in switching logic circuitry therefore according to our logic the multiple channel can be accessed and problem of multiple switching is overcome by router.

HISTORY OF ROUTER

Router is mainly used for routing the signal from input to the output, in the CATV system and CCTV system. In the past, switcher was used instead of router for this purpose. Video routers are manufactured in a wide variety of sizes and styles, as well as signal formats. Many have the flexibility to mix signal formats in the same frame, which means they could be used to route both digital and analog video, VGA and audio, and so on. Others are dedicated to a single format. Some, usually video switchers, are highly specialized, such as those that can automatically switch from one source to another if the signal is lost on the original input. Because routers are so central to an installation’s layout, many are designed to allow expansion to add a greater number of inputs, outputs, or both, as future needs demand. Video routers and switchers can actually be mechanical devices, which mean they will make the routing signal paths through a mechanical switch. These are seldom used for any kind of demanding application, because the mechanical contacts become electrically noisy, and in time the actuators tend to be temperamental. Active, electronic switching is quieter and far more reliable. Now in these days different types Audio-Video Router is in general use, For example, 4X4 Audio Video Router, which routes four inputs to the four different outputs. Similarly, 8X8 audio video router, 12X12 audio video router, 16X16 audio video router.

COMPARE WITH SWITCH

A router is more sophisticated device than a switch. A switch is used for wired networking connection while router can connect wired or wireless (Wi-Fi) networks.

In the past, switch was used instead of router for routing the signals from input to output. The basic difference between switch and router is that the switch can control only one output means there is only one to one logic while router can control more than one output and there is  one too many logic. Thus if we want to route one input terminal on more than one route or we want one input terminal available at several output terminal then it is not possible with switch, while router can do this job easily. Normally if we use switch then it will switch the input in about one second but instead of switch we can use audio video router which use logical IC’s and due to the use of Logical IC’s switching will be done in micro seconds. So fast switching of audio and video is possible. Routers can actually be mechanical devices, which mean they will make the routing signal paths through a mechanical switch.
