The copper line is susceptible to interference, and the signal is also prone to get weak where long distances are involved. For this reason, amplification may be called for along the way. The early copper network only transmitted analog signals, which require a dedicated circuit since they travel in a continuous stream. This can be both a blessing and a curse.
On the upside, a dedicated circuit is as reliable as circuit technologies come. But it is handicapped by the fact that the line has to be reserved for one call and one call only.
This type of switching is what is known as circuit switching. In those days, operators would sit by one giant wooden switchboard, plugging copper wires into a common patch panel. Long-distance calls were unbearably costly because calling long distance was akin to renting the use of a very long piece of copper wire each time you wanted to make a call. As technology advanced, so too did circuit switching. The first stab at automated switching came in following the invention of the Strowger switch.
It was also known as a step-by-step SWS switch due to its operational features. Later, it pressed into service after the invention of the rotary dial. It changed once, and then twice, finding favor among the masses. Eventually, it was phased out by the crossbar switch. Despite their reliability, crossbars were faulted for being complicated, bulky, and costly.
You can only imagine how challenging it must have been to provide excellent customer service under those conditions back then. Thankfully, a disruption came in the form of one of the best things to happen to the world since man bashed two stones together to ignite a fire: the invention of the transistor.
The transistor heralded the electronic exchange era, which slowly paved the way for the digital network. Rather, it uses the underlying network to transmit voice and data messages independently through the switches. A copper line is a bi-directional 64Kbps service capable of carrying human voice both ways at the same time i.
For this to happen, a critical hardware component needs to be added to the PSTN. Enter the modem. This is a device that was designed to exploit the digital nature of the public switched telephone network without overhauling your entire phone system. This should come as good news for small business owners who are not planning to upgrade their analog communications systems any time soon, especially considering the wealth of options available on the market. For example:.
DSL Digital Subscriber Line technology makes it possible to transmit data over your copper-wire telephone system. The network in turn routes data to the World Wide Web. This type of service is most popular among small business setups.
Because it provides just enough bandwidth for a sizeable number of users to access the Internet. ISDN makes it possible to transmit both voice and data over a single copper line. To establish a network connection, users have to dial in. The fees are determined by the duration of the transmission. ISDN promises faster call setup and higher quality calls compared to the classic telephone system. Businesses also prefer it because it comes with the option of integrating with other phone systems PABX.
This allows them to take advantage of a host of other features. For example, using a number range, queues, groups, on-hold music, etc. It is ideal for larger businesses or those looking to expand in the near future. In this era of the mobile phone and smart everything, you could be forgiven for thinking landline phones are dead and buried.
Their death knell may have been sounded by the emergence of digital communications, but it seems analog systems will stick around for a while longer. Makes you wonder then, how much does it cost to maintain a POTS line?
Overall, you'll find the cost of maintaining a POTS line is much higher. But there are still situations where the old telephone system costs less to implement. This is actually why the plain old telephone service is largely considered the Carrier of Last Resort CoLR : the network we turn to when all else fails. A report by the U. SIP Trunking.

In another way, POTS will always be with us because of the physical infrastructure; all of those copper wires strung on telephone poles and the thousand of miles of copper buried in the ground are being repurposed to support VoIP technology and high speed bandwidth.
Used in conjunction with fiber optic cabling, the copper used for POTS is an integral part of our modern communication infrastructure. As you consider whether or not your business should get rid of any POTS line, you may find that it is important to know why you have them in the first place. As mentioned earlier, you may very well have to have POTS lines to support fire and security. And even though VoIP fax has come into its own and is the preferred way to fax, some businesses do not want to get rid of their traditional fax machine, which in turn requires a good old fashion POTS line.

However, these devices were complicated and costly, as well, leading to the creation of the transistor. Instead, it transmits voice and other messages independently through the switches.
Modems Modems were created to support the transmission of digital signals without overwhelming the system. To do so, a transceiver connects to your PC and uses the local phone network to connect to an ISP network.
This enables your use of the internet. This type of modem is useful to small businesses. To enable a connection, users dial in. And the fees for such service rely on the duration of the transmission. Large companies or businesses looking to expand in the future may find this modem more suited.
However, in areas where cellular or internet coverage is slow or inaccessible, copper lines are more reliable. One must keep in mind that other elements factor in as well, such as:.
Voice over IP uses your existing internet connection to transmit voice and data from one party to the next. VoIP makes it possible to connect remote offices and keep communications stable.
