VoIP. Is Phone by Wire Nearly Dead?

Zoomup
Hard wired phone lines. Just how long will we have them? And just how many metres of cable are there on those big pictured cable drums?

    Hello,

    As engineers, we should get the terminology right. Voice over Internet Protocol (VoIP) technology enables traditional telephony services to operate over "data/computer" networks by converting your voice into a digital signal allowing it to be "switched" over the digital network and then converted back into voice at the other end. Simply put, it is phone service delivered over the "switches" (exchanges) using internet protocol. The "old" circuit switched telephone exchanges are practically non-existent since IP switches are cheaper to run. So even "old fashioned" phone calls are switched using IP. The only part of the "old technology" is the copper wire to your local exchange and you rent this copper wire (so that your call can be switched by any competitor and not necessarily BT)

    The old law still applies: Only the "old" land-line phone is supposed to work even if the area has no electricity and the operator has to guarantee that you can make emergency calls. This is done by actually powering the phone from telephone exchange, so unlike computer, VoIP phone, etc. you do not need home electricity (or power backup)  to make phone calls. You will note that there is always a disclaimer for VoIP (not suitable for emergency calls, ...). Mobile phones have made the above part "redundant" since you can now call emergency services using your mobile phone, provided you have good coverage!

    Line Rental is the charge for using the "copper wire" from your house to the local telephone exchange. This copper wire is still needed to use another digital technology on it called ADSL     (Asymmetric Digital Subscriber Line)  so that you can use your copper wire to transfer digital signals (and by the can make VoIP calls). With Fibre Optics, you do not need copper wire but I am sure you will still have to pay to rent the fibre from your home to first exchange.

    BT was broken up into "local" part as BT Consumer (who owns copper wires/fibre optics to consumer premises) and BT Enterprise - the backend part which can be used by competitors as well. The breakup was mandated to ensure that BT Enterprise did not subsidise BT Consumer indirectly.


    Unless you have excellent mobile coverage and good enough for your Netflix, You Tube, etc. or you do not use any of that, one is stuck with BT Consumer and hence Line Rental charges.


    Nothing to do with ADSL, etc. - it is "pipe" which is need for fast internet services.


    Best wishes,
