Method for concentrating subscribers in a local exchange (LE), which comprises an exchange terminal ( ), a V5 interface (V5) connected to the exchange terminal, a group switch ( ) and an interconnecting line ( ) between the exchange terminal and the group switch for connecting subscribers connected to the exchange terminal to the group switch. According to the invention, a number of V5 interfaces (V5) are connected to the exchange terminal ( ) and the exchange terminal is connected to the group switch ( ) via the interconnecting line ( ), thus forming between the exchange terminal and the group switch an internal interface within the local exchange for concentrating V5 subscribers.

Method for concentrating subscribers in a local exchange

A procedure for concentrating subscribers in a telephone network comprising a local exchange (LE) provided with a first exchange terminal (1), a remote subscriber stage (RSS) provided with a second exchange terminal (2), a V5 interface (V5) connected to the second exchange terminal, and an interconnecting feeder (3) between the first and second exchange terminals through which subscribers connected via the V5 interface to the second exchange terminal are connected to the local exchange. According to the invention, a number of V5 interfaces (V5) are connected to the second exchange terminals (2) and the second exchange terminal is connected via the interconnecting feeder (3) to the first exchange terminal (1), thus forming a concentrating interface between the first and second exchange terminals.

Method for concentrating subscribers in a telephone network

In a telecommunication system comprising a telephone exchange (LE), an access node (AN) connected to the telephone exchange via a standard V5 interface and a data network (DN), a procedure for setting up a direct data connection between the access node and the data network from a terminal device. According to the invention, a data network subscriber is created in the access node (AN), and when the data network subscriber starts call setup, this is not signalled to the local exchange (LE) according to the normal V5 practice. The data network subscriber's call setup request is handled locally in the access node, where also a dial tone is generated for the data network subscriber. A data connection between the data network subscriber and the data network is set up directly from the access node on the basis of the dialing given by the data network subscriber.
