facilities-based operator, service-based operator telecom.

[kalinkas]

Здравствуйте!
Подскажите, как точно на русском называются эти два вида операторов (facilities-based operator, service-based operator)
Нашла определения на английском, но не хочу гадать.
Facilities-based operators (FBOs) are operators intending to deploy any form of telecommunication network, systems and facilities to offer telecommunication switching and/or telecommunication services to other licensed telecommunication operators, business, and/or consumers.
Service-based operators (SBOs) are operators intending to lease telecommunication network elements such as transmission capacity, switching services, ducts and fibre from any FBO licensed by IDA to provide telecommunication services to third parties or resell the telecommunication services of FBO.
Спасибо.
