1. Apparatus for use in a communications system for providing access to telecommunication services, comprising:
- a user terminal operable by a subscriber for receiving telecommunication services;
a net terminal coupled between the user terminal and an access point associated with a communications network including a first high speed, broadband modem, a second, lower speed, narrowband modem, and first switching circuitry selectively controllable to direct signals to and from the user terminal via the communications network using the first modem or the second modem;
the access point including one or more high speed, broadband modems, one or more lower speed, narrowband modems, and second switching circuitry, different from the first switching circuitry, selectively controllable to support a connection with the user terminal via the communication network using one of the broadband modems or one of the narrowband modems; and
a controller for controlling the first and second switching circuitry to support the connection.

Abstract
The present invention relates to an apparatus in a telecommunication system for providing access to telecommunication services to subscribers at user terminals, each of which is separately connected to at least one access point via high speed modems and a communication network. The at least one access point includes high speed modems with filters. Switching can be performed from a broadband connection to a narrowband connection, if necessary, to guarantee at least one connection.

7. A method for use in a communications system for providing access to telecommunication services to a subscriber associated with a user terminal operable by the subscriber for receiving telecommunication services, comprising:
-
providing a net terminal coupled between the user terminal and an access point associated with a communications network including a first high speed, broadband modem, a second, lower speed, narrowband modem, and first switching circuitry selectively controllable to direct signals to and from the user terminal via the communications network using the first modem or the second modem, providing at the access point one or more high speed, broadband modems, one or more lower speed, narrowband modems; and
second switching circuitry, different from the first switching circuitry, selectively controllable to support a connection with the user terminal via the communication network using one of the broadband modems or one of the narrowband moderns; andcontrolling the first and second switching circuitry to support the connection. - View Dependent Claims (8, 9, 10, 11)
