When referring to traditional "landline phone alarm monitoring", this communication path utilizes a circuit switched telephone that uses a solid core, twisted pair copper wire, and plugs into a two or four pin wall jack. There a few alarm industry abbreviations often used for sending alarm signals over the traditional phone line, such as plain ordinary telephone services "POTS" and public switched network "PSTN".
Over the past 100 years, the copper wire phone technology has not changed too. Traditional landline phones are based on an analog technology which transmits signals through a series of exchanges and physical switch boxes that connect calls between two phones.
Although this hardwired copper technology is very old, it is ironically very reliable. Because landline phones use physical wire connections to make and receive calls, they arenít as susceptible to the service interruptions and slowdowns of other services. However, they are susceptible to deliberate line cutting and/or tampering.
The negatives of landline phone are that the wiring is very labor intensive, confusing, and it takes up alot of space. So, the Federal Communications Commission "FCC" is passing new legislation against traditional landlines and recommending consumers to ditch their landlines.
When referring to "Digital VoIP alarm monitoring", unlike a traditional phone line, this communication path does not use traditional twisted pair copper wire. With VoIP, the phone is connected using the same broadband internet connection which plugs into your computer or router.
By sending alarm signals via this method, the calls are converted into digital signals within the phone itself. Unlike the traditional phone setup, Digital VoIP does not need physical exchanges. Therefore, less space needs to be dedicated to newer digital VoIP phones.
