Voice Communication System (VCS) to Airports

The purchaser intends to procure a contract for Voice Communication Systems (VCS) for operation of connected communication channels to six regional airports. The communication channels in question consist of radio ground-to-air, radio ground-to-ground and incoming telephony lines. The airports have different local needs, which is why the system must be modular in design, with one or more options for communication interfaces and number of working positions. It has been determined that the procurement should only include VCS equipment, as there are already existing radio stations and telephony lines installed locally.
