Embodiment Construction

[0018] now refer to figure 1 , a general block diagram of the communication system 100 is shown, along with a block diagram commonly referred to as a circuit pack or line card in accordance with the present invention. The present invention can conveniently support symmetric xDSL service, asymmetric xDSL service, and POTS with a single line card, thereby reducing the cost and saving space of the telecommunication system. Specifically, the telecommunications system 100 supports symmetric services such as HDSL, HDSL2, SHDSL, or SDSL, asymmetric services such as ADSL or ADSL lite, and POTS. Communications system 100 includes customer premises equipment (CPE) 102 , all placed to the right of dashed line 104 . The CPE 102 shown includes a personal computer (PC) 106 and a POTS phone 108 connected to a user termination unit (xTU-R) 110 . xTU-R 110 provides an interface between incoming and outgoing communications over subscriber lines 112, such as twisted pairs or loops. It should ...

Abstract

A line card and method is provided which supports symmetric and asymmetric telecommunication services, such as symmetric and asymmetric DSL services. The line card may support concomitantly POTS and asymmetric DSL services or support DSL services. A xDSL interface provides processing for DSL signals and a POTS interface provides processing for POTS signals. The line card is capable of switching operating modes or which services-it is supporting. Preferably, the line card is capable of switching operating modes during a communication session. The line card may switch modes based on instructions received from external devices, such as CPE or far end equipment, based on preprogrammed software or based on operation of the line card.

Description

technical field [0001] Field of the Invention This invention relates generally to telecommunications systems providing data and voice communications, and more particularly to line cards and methods supporting POTS and asymmetric DSL, and supporting DSL. Background technique [0002] Providing consumers with cheaper, faster, and more comprehensive high-speed data communications is an eternal and urgent need for telecom service providers. For service providers, users use many different high-speed data communication services to complicate matters. Some of the methods currently commonly used to send data are, for example, Integrated Services Digital Network (ISDN) services, Digital Subscriber Line (DSL) services, and European Periodic Pulse Meter (PPM) or Telex (Telex) services. [0003] These methods are also divided into many types, making things more complicated. For example, the DSL series of high-speed data communication includes various service hosts, usually recorded as...
