Nurse Call Systems
Essential patient-to-nurse communication for hospitals, medical centres and clinics.
Communication Systems
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.

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.
