What Is the Public Switched Telephone Network?

The Public Switched Telephone Network (PSTN) has existed since the 1800s and allows callers to communicate with each other globally. To connect calls, PSTN networks use underground copper wires, switches, and other infrastructures.

They are also known as fixed lines, landlines, or analog. The PSTN network is regulated by government bodies even though some parts of the legacy system have been digitally upgraded.

PSTN calling works via a network of interconnected circuits and switches. When the call is made, the phone converts voice into electrical signals sent to the local exchange. In the exchange, leveraging a system of routing protocols, it determines the right path for the call to take through a series of switches and trunk lines that are high-capacity transmission lines.

PSTN for Businesses

For any business, a PSTN system can be set up using an individual line for each employee. This works well for many employees, but adding more lines can be costlier. This is why larger businesses prefer to use the PBX system, as it transforms the business phone system into a central office; the incoming calls made to your business will reach the PBX system and then be routed to the specific extension of employees. This system uses features like auto-attendants to get callers to the right destination.

PSTN is a popular communication system that offers a comprehensive set of features, such as

• Reliability - Guaranteed 99.999% operational time with redundant infrastructure and solid backup routes, ensuring consistent and seamless service during emergencies.

With many businesses switching to VoIP service, PSTN remains a popular choice for most companies for a few crucial reasons. Listed below are the reasons,

1. Robust Infrastructure - PSTN services have a robust in-built infrastructure that has been improved constantly over the years. It has several networks of local exchanges, trunk lines, switches, and international gateways that spread worldwide coverage.

2. Consistent Call Quality - These networks use circuits for every call, ensuring reliable and consistent voice communication with zero latency. Businesses depend on PSTN for all emergency communications due to its consistency in delivery.

3. Increased Security and Privacy - PSTN works on a network with tight security measures, and the PSTN line providers ensure compliance with regulatory and encryption standards to protect user data and prevent unauthorized access. This level of robust security makes PSTN the best choice for businesses that depend on sensitive communications for data protection.

Let's understand the cost incurred during the installation and use a PSTN phone system in the home or office.

• Cost for Consumers - To set up a PSTN connection at home, you will need a telephone set and the right PSTN provider. Imagine buying a decent phone from any shop for $60 and a basic phone service with unlimited calls costing around $30 monthly. There are many plans with unlimited local and national calls at affordable costs and monthly plans.

• Cost for Businesses - Businesses will require separate lines for each employee while getting a PSTN phone system. For some reason, businesses prefer VoIP over other traditional phone systems. If cases involving small businesses within ten employees can choose a monthly plan for around $30 per month per connection. For connecting with more than forty employees to the PSTN service, a key system unit will be the right choice as it offers an array of features, and KSU costs approximately $800 or more for each line.

There has been a slow decline in PSTN usage as other digital communication technologies, such as mobile networks, VoIP, and others, have become more dominant and cost-effective. Most businesses are moving away from PSTN to choose modern alternatives for flexibility, advanced features, and reduced costs.

Some countries, like the Netherlands and Estonia, have shut off their PSTN networks, while others, like the UK, New Zealand, and Denmark, plan to terminate the network in six years. However, some transition strategies are being adopted in hybrid systems that integrate PSTN and VoIP for a hassle-free migration process. As 5G and IoT technologies emerge, more rampant innovations and superior communication solutions will emerge.
