A system is described for providing communication services and this system comprises a communication network with a number of exchanges and a number of connection points. Each connection point is connected by a fixed line to an exchange and is adapted to connect at least one communication terminal to the corresponding exchange. First connection points of the number of connection points are in an operative state and second connection points of the number of connection points are in an inoperative state. Operative connection points allow a communication terminal connected thereto access to at least one communication service through the system by having been assigned a unique address from a first group of unique addresses to each of the operative connection points. The inoperative state of the second connection points includes a standby state and the exchanges are adapted to recognize the standby state of an inoperative connection point used by a communication terminal to access the system and to allow the communication terminal connected to this inoperative connection point access to a transaction server through the corresponding exchange. The transaction server is adapted to switch an inoperative connection point into the operative state by assigning a unique address from the first group of unique addresses to this inoperative connection point so that the inoperative connection point is changed into an operative connection point.
