[0012] Another disadvantage of the prior art is that the splitters S used in the subscriber terminal equipment TEE and the subscriber switching center TVS are analog low-pass filters
Analog low-pass filters take up a lot of space and are not compatible with high packing density, especially in subscriber switching center TVS

Embodiment Construction

[0067] Fig. 2 schematically shows an arrangement according to the invention of a hybrid DSL system 10 for transmitting hybrid DSL data.

[0068] The hybrid DSL system 10 is part of a subscriber terminal device 20 (not shown), or a part of a subscriber switching center 30 (not shown) and is connected to corresponding other devices via a subscriber access line 2030 .

[0069] The hybrid DSL system 10 according to the invention has a baseband transceiver 101 and a non-baseband transceiver 102 .

[0070] The baseband transceiver 101 is connected to the non-baseband transceiver 102 via a data link 103 .

[0071] A primary splitter 104 integrated with the baseband and non-baseband transceivers on a common circuit board in the hybrid DSL system 10 separates the baseband and non-baseband frequencies and splits the frequencies received via the subscriber access line 2030 The baseband of the signal is provided to the baseband transceiver 101 . Likewise, the primary splitter 104 provid...

Abstract

The hybrid DSL system ( 10 ) for transmission of hybrid DSL data via a subscriber access line ( 2030 ) has a baseband transceiver ( 101 ) for transmission of first data in a base frequency band via the subscriber access line ( 2030 ) at a first data transmission rate, a non-baseband transceiver ( 102 ) for transmission of second data in a non-base frequency band via the subscriber access line ( 2030 ) at a second data transmission rate, and a data link ( 103 ) for interchanging parameters between the baseband transceiver ( 101 ) and the non-baseband transceiver ( 102 ) in order to increase the overall data transmission rate of both transceivers ( 101, 102 ).

Description

technical field [0001] The present invention relates to a hybrid DSL system for transmitting hybrid DSL data via a subscriber access line in order to increase the overall data transmission rate of two transceivers. Background technique [0002] The technical field to which the present invention pertains relates to the transmission of two DSL (Digital Subscriber Line) services over a shared subscriber access line between a subscriber terminal device and a subscriber switching centre. [0003] According to the prior art, two DSL services transmitted over a shared subscriber access line are essentially an ISDN service and an ADSL service. According to the respective standards of ISDN and ADSL, the ISDN frequency band (0-80 kHz) and the ADSL frequency band (20 kHz to 1.1 MHz) overlap. If, for example, a subscriber terminal device is transmitting both an ISDN signal and an ADSL signal, the two signals must be separated from each other using out-of-band methods. [0004] US-A-5,...
