PABX Internal Telephone Exchanges

Internal telephone exchanges (PABX) are one of the most important ways for people to communicate inside companies, institutions, factories, hotels, tourist villages and villas. GTS supplies and installs PABX systems — most notably from the Japanese brand Panasonic — sized to the number of lines and the functions you need.

PABX Telephone Systems

What is a PABX system?

A PABX (Private Automatic Branch Exchange) is a private telephone exchange inside a building. It connects all internal extensions to one another free of charge and shares a limited number of external lines among them. Capacities vary according to the number of external and internal lines the customer wants, and the capabilities and functions vary according to the customer’s needs.

Frequently asked questions

PABX Telephone Systems: frequently asked questions

How do I choose the capacity of a PABX?

Start from two numbers: how many external lines you need and how many internal extensions you need. GTS then recommends an exchange with that capacity plus room for growth, and with the functions that match the way you work.

Which PABX brand do you recommend?

One of the best-known brands for modern telephone exchanges is Panasonic of Japan, which offers a wide range of capacities and functions for everything from a villa to a large hotel or factory.

Can the exchange be expanded later?

In most systems, yes — lines and extensions can be added with expansion cards up to the maximum capacity of the model. That is why we ask about your expected growth before recommending a model.
