VoIP Phone System

A voice over Internet Protocol, or VoIP, transmission is initiated by converting voice into digital format. This can be done by Analog telephone adaptor (ATA) or by the computer itself using software. In the Public Switch Transmission network (PSTN), the dialing of the number initiates the call by connecting the call to the public switch and routing the call to the correct partys telephone number through the telephone network.

A VoIP network also has similar functions like that of PSTN, in addition to the IP provider and Internet Service Provider (ISP). The major components of a VoIP network are user devices (one or both ends), a call processing server, VoIP gateways, gatekeepers and an IP network. The user device consists of VoIP phones, traditional phones with accessories and computer-based devices. VoIP phones may be hard or soft phones.

A VoIP hard phone is like a traditional phone, but instead of a phone jack, it has an Ethernet port through which it communicates directly with a VoIP server or another VoIP phone. It doesnt need a personal computer, only an internet connection. These hard phones may also come cordless.

A dialup hard phone is one with a built-in modem instead of an Ethernet port. A wifi hard phone is built with a wifi transceiver to connect to a wifi base station to be connected to a remote VoIP server. This can be used to transfer calls to a gsm network.

A soft phone is run by software in the computer. This requires appropriate hardware such as a microphone, a speaker or a USB port. Once dialed, the phone number is processed by the call processor, which is actually hardware running a database mapping program called soft switch; the software manages all connections. This is also called IP PBX (private branch exchange), similar to the PBX of the PSTN lines.

There are gateways and gatekeepers that control the call admission and bandwidth management. They also control the creation of IP packets that contain the voice data and other information about the call.

Finally, there is the IP network, which consists of distributed routers ensuring connectivity. This IP logical switch is referred to as the soft-switch architecture. These four components form the phone system for VoIP, in addition to the software and various protocols through which the call is smoothly communicated.

The Basics of Buying Ladies Golf Clubs - Part 1

Ladies are at a disadvantage when it comes to putting together a set of golf clubs that fits them well and from which they can get the most out of their games. The reason is that there are few choices in normal off-the-shelf ladies golf clubs. With typically less than 10% of sales for a golf club company coming from ladies golf clubs, there are simply few choices in club styles, shaft flex, swing weights, or lofts normally available in most golf shops. An exception to this is the excellent line offered by Nancy Lopez Golf Clubs. That is the subject of another article, but you can easily find their web site with a simple search.

In general women have slower swing speeds than men and need shorter clubs and higher loft. There are of course women with better and stronger swings than most men. Lorena Ochoa of the LPGA tour averages about 270 yards on her tee shots. this is astonishing for a woman who weighs about 115 pounds! She is the top rated professional woman player in the world, however, and this article is meant for women with less ability than the top LPGA pros possess.

Driver Considerations

You must know your swing speed with at least a driver and preferably with both driver and 5 iron. Women who can swing the driver more than 70 MPH can use titanium faced drivers effectively and take advantage of the spring effect off the face that such a club offers. If your driver swing speed is more like 60 MPH, you would have to find a special titanium face, and these are not readily available. If you are that serious you will probably be having custom ladies golf clubs made by a certified fitter and club maker. So in that case ask your club maker if he or she can offer options. As for club face loft, the slower your swing, the higher the loft is needed. If you can easily get the ball in the air, a loft of 13-14 degrees should work well for your driver. If you have trouble getting the ball in the air, you may need to use a 16 degree 3 wood to get the most out of your swing. Other ways to help get the ball a bit higher in the air are to use an offset hosel or a more flexible shaft.

fairway Woods

fairway woods are critical clubs for women or men with slower golf swings. If your swing speed is in the 60MPH range, you should start your fairway woods with a 5 wood and leave out the 3 wood. Your other woods would then probably need to be a 9 and 13 wood. The reason for skipping an odd numbered wood is because you wont be hitting the ball that much farther with a 5 wood than you will with a 7 wood, for example. In other words the gap in distance between the two clubs is not enough to justify carrying the other club. Regarding club length, there should be at least a one inch difference for each odd numbered club. That is, the 7 wood should be one inch shorter than the 5 wood, and the 9 wood should be 2 inches shorter than the 5 wood, for example.

For women who swing 70 MPH or greater, a 3 wood could be a good choice, but it should have at least a 16 degree loft in order to keep the ball in the air longer. this group of golfers can justify having every other odd number wood in their bags, such as 3, 5, 7 and 9 woods, for example.
