Abstract: PROBLEM TO BE SOLVED: To provide service to a new remote subscriber's line unit through the use of the flexible bandwidth of a data network by providing a remote line unit, etc., which is remotely located from a telephone exchange and constituted to interface with one of bearer channels connected with a data network and a wired terminal. SOLUTION: An access network head end 208 sets one or plural bearer channels of a packet data capacity toward respective remote line units 216, 218. In another word, a set quantity of data packet traffic is reserved through a data network 214, and the end 208 controls and maintains a bandwidth required through the network 214 by this reservation. Then, the units 216, 218 provide a telephone service to analog telephone sets 224, 228, 234 and digital telephone sets 230, 236, 238.

Abstract: PROBLEM TO BE SOLVED: To provide a more flexible service to a cable terminal through the use of the flexible bandwidth of a data network by providing first and second remote line units, access network head end, etc., for varying the ratio of the bandwidth depending on a prescribed condition. SOLUTION: An access network head end 208 assigns a larger number of bandwidth to a remote line unit 218 handling a business canvas 240 during daytime and assigns a larger number of bandwidth to a remote line unit 216 handling a residence district 232 during nighttime. Thus, the assignment of the bandwidth is dynamically varied between the line units like this. For example, when a fire or another disaster occurs in the district 232, in order to support activities in an emergency, a larger number of bandwidth through a data network 214 are temporarily assigned to the district 232. Then, the unit 216 provides a telephone service to analog telephone sets 224, 228 and a digital telephone set 230.
