I had been using my own adsl modem up until the point it completely stopped working. I decided to rent a modem from the company after that. And I was surprised how stable to connection can be with the modem provided by telecom. I think that if somebody is renting you a wire it has some sense to rent terminators as well. In this case the company can tweak entire infrastructure for their customers.
