Abstract
Procedure for connecting a subscriber to a telephone exchange in a data communication system comprising a telephone exchange (LE) with a number of subscribers defined in it, an access network (AN) connected to the telephone exchange via a first V5 interface (V5) and comprising a first access node (AN1), a second access node (AN2), which is connected to the telephone exchange, and a subscriber terminal (TE), which is connected to the local exchange via the access network and/or a concentrator. According to the invention, the second access node (AN2) is connected to the first access node (AN1) via a second V5 interface, the connection between the subscriber and the telephone exchange (LE) being this set up by cascading two V5 interfaces.
Claims14
A method for connecting a subscriber to a telephone exchange in a data communication system comprising:
- predefining a telephone exchange with a number of subscribers in it,
- connecting an access network (AN) to the telephone exchange via a first V5 interface wherein a first access node, a second access node, which is connected to the telephone exchange, and a subscriber terminal, is connected to the local exchange via the access network or a concentrator, and wherein the second access node is connected to the first access node via a second V5 interface, and
- connecting the subscriber and the telephone exchange cascading two V5 interfaces.
