While this operation is simple, it is entirely based on analogue technology, which can cause challenges when many phone calls have to be sent down a single line. Telephone calls have a narrow bandwidth, making them more muffled but allowing more calls to be multiplexed down the same transmission line. Multiplexing is an attempt to try and improve bandwidth.

This challenge is made worse when considering that many receive internet through their landline in the form of broadband. Even to this day, anyone who uses their landline for the internet must use an ASDL splitter that separates analogue telephone conversations from broadband services.
Recently, an announcement outlined how old analogue methods for transmitting telephone conversations will be replaced with a digital system. This switchover is not due to occur until 2025, but telephone conversations will require an internet connection when it does.
One of the most significant advantages of an all-digital system is that digital data is far easier to compress and transmit than analogue audio signals. Compression means that more conversations can be transmitted over a single line, and the quality of these calls can be significantly improved. As such, the introduction of the digital telephone should see muffled voices disappear and call quality approach that of video calls.
It is no surprise that elder generations generally lack technological integration. This can be for several reasons, including resistance to change, inability to learn new systems, and the rapid rate of technological change is too fast. The replacement of analogue systems with digital services does not increase the complexity in use but can create challenges using newer devices. Unless new digital phones are designed with an old-fashioned feel, many could face challenges when using new digital equipment.
While there are concerns with the analogue to digital switchover, it has to be done to improve telecommunications and increase data rates. The replacement of any technology will always be left behind, and while engineers do their best to support such individuals, technology must continue to progress.
Note: If the telephone interface is also to be used as a local phone, make sure to implement safe proof logic design to prevent false triggering a preset during a call. (e.g. Dial 1800 number and your system goes muted because of the 1 recalling a preset )
This is where GaN becomes very helpful, as we can quickly go from a 5 V supply voltage with GaAs to a 28 V supply voltage in GaN, and the achievable power goes from 0.25 W to almost 8 W simply by changing from GaAs to GaN technology. There will be other considerations to look at such as the gate length of the process available in GaN and if they can achieve the gain you need at the high frequency end of the band. As time progresses, more of these GaN processes become available.
With VoIP, when the power goes out, one can handle incoming and outbound calls using a range of mobile devices that only require access to a data connection. Calls can be rerouted almost instantly to other company locations if required. 2ff7e9595c
