Advantages of Digital Telephone Systems
The difference between an analog phone system and a digital phone system is the same as that of a typewriter and a computer. While analog systems use electrical impulses, digital phone systems compress and convert voice information into a binary code, a series of 1s and 0s and transfers is the other end where it gets reassembled.
We can’t quite say that one technology is better than the other. Analog phone systems have been here for years. It is easy and quite inexpensive in nature. However, analog systems can only carry so much data. That aspect is completely removed by digital systems which can carry huge volumes of data quite easily. The best part about digital technology is that it knows what it should be at the end of the transmission. It therefore corrects any errors which may have occurred during transfer of data. That only means one thing – clarity. Conversations will be distortion free.
And that isn’t all. Digital telephone system technology is so designed so as to fit in a lot of those 1s and 0s together in the same space which an analog signal uses. That means you can get a lot more features through digital technology. That is why your work phone offers so much more than your average home phone. Digital phones are connected by CAT-5 cables. This high-speed cable carries voice information to and from a digital switch, which sends the call out over a broadband internet connection. The phone itself is like a simple computer having a number of functions. When the user speaks into the phone, the system converts the voice to binary code, compresses it for travel and sends it along the connected call. Incoming noise is converted and compressed at the switch and decompressed at the user’s phone.
There are these drawbacks in the case of digital phone systems. Since these devices constantly translate, code, and reassemble you voice, you won’t get the same rich sound as you do get will analog. Better clarity yes, but not better quality. Moreover the digital systems are quite expensive. It isn’t just the technology which is expensive. The setting up of the entire phone system entails considerable expenditure too.
However, the prices will come down as it gets available to more people in due course of time. And eventually, it will become common and due to advancements in technology the lack of quality too will hopefully be eradicated. And then clarity and quality with Digital TelePhone Systems will be available to everyone, at affordable rates.
