What is Carrier Pre Select (CPS) in Telecom Systems?
To fully understand what is carrier pre select, it is important to break it down in telecom terms. Carrier Pre Select (CPS) is a telephone service feature that automatically routes outgoing calls through a selected carrier instead of the default local telephone exchange.
In traditional landline systems, users are usually assigned a default telecom provider. However, with what is carrier pre select, users can choose a preferred carrier in advance. This means all outgoing calls automatically go through that provider without dialing extra prefixes.
The main purpose of what is carrier pre select is to give users more flexibility and cost control. It is commonly used in residential landlines, corporate phone systems, and office communication setups where call volume is high.
Key characteristics include:
- Automatic call routing through chosen carrier
- No need to dial carrier selection codes
- Works at network level, not handset level
- Supports both local and international calls
Telecom regulators in many countries introduced CPS to increase competition among service providers. As a result, customers benefit from better pricing and improved service quality.
In modern telecom networks, what is carrier pre select is often integrated with other services like number portability and VoIP systems. This makes it easier for users to switch providers without changing their phone number or hardware setup.
How Carrier Pre Select Works in Modern Networks
To understand what is carrier pre select, you need to see how it functions behind the scenes. When a user makes a call, the telecom network checks which carrier is assigned as the default through CPS settings.
Once the system identifies the selected provider, the call is automatically routed through that carrier’s infrastructure. This entire process happens within seconds and is invisible to the user.
Step-by-step process:
- User dials a number
- Local exchange receives the call request
- System checks CPS configuration
- Call is routed to selected carrier
- Carrier connects the call to destination
In most systems, what is carrier pre select works using database mapping between the user’s phone line and the chosen carrier. This ensures consistency and prevents accidental routing through default operators.
Moreover, telecom companies often allow users to override CPS temporarily using prefix codes. This flexibility ensures that what is carrier pre select does not restrict user choice completely.
Another important aspect is billing. Since all calls go through the selected provider, billing is centralized. This makes cost tracking easier for both households and businesses.
In modern VoIP and hybrid networks, what is carrier pre select is often automated using cloud-based routing systems, making it more efficient than traditional setups.
