Description
Technical field
The present invention relates generally to telecommunications, and specifically, the Digital Subscriber Line (DSL) that relates to through having embedded voice gateway module provides speech.
Background
The modern telephone system mainly is designed to transmit voice signal between the terminal of remote location.Traditionally, telephone system adopt switch to be connected by network with other electronic equipment and be the calling specified circuit by.Before nineteen sixties, telephone system mainly adopts analog switch and other analog machine.Along with the unify function of other digital electronic device of department of computer science increases, telephone system begins to comprise digital switch and other equipment.For example, developed digital loop carrier (DLC),, and then linked to each other with the central office through high-speed digital line so that allow to select to be routed to connection away from the position of central office from a plurality of users.Yet this digital device still mainly is designed to handle voice signal.
As time goes on, telecommunication system has been used for transmitting voice signal other data in addition between the terminal of remote location.Transmitting data is that traditional telephone system has been brought various problems.For example, as mentioned, telephone system is designed to transmit the low bandwidth voice service.Regrettably, these low bandwidth channel are for data service that the popular more high bandwidth that becomes is provided, brought serious obstruction as internet and other data network.
In order to occupy a part of this data market, telephone industry has developed the one group of technology that is collectively referred to as " Digital Subscriber Line (DSL) " business, for example ADSL (Asymmetric Digital Subscriber Line) (ADSL), high bitrate digital subscriber line (HDSL), rate adaptive digital subscriber line (RADSL) and symmetric digital subscriber line (SDSL) etc.These business connect being used to transmit provide at a high speed on the existing copper cash of Plain Old Telephone Service.These professional various modulation schemes and other technology of adopting are transmitted data so that allow at a relatively high speed on existing copper cash.Except that data, some technology in these DSL technology allow the shared physical circuit of multiple phone line, therefore, other copper cash need not be installed between consumer and network connect the capacity that just can improve system.
Regrettably, the DSL voice service is not directly and the legacy equipment compatibility in the public switch telephone network (PSTN).For example, the DSL voice service conventionally is included in asynchronous transfer mode (ATM) grouping or the cell.This and time division multiplexing (TDM) the form difference relevant with PSTN.In addition, the ATM grouping is direct and the signaling of PSTN and other requirement compatibility.Therefore, certain some place is provided with special voice gateway in the network that for example enters PSTN from the DSL voice service of a plurality of DLC.This voice gateway provides conversion between ATM and the TDM form and processing signaling and by desired other function of V5 of network standard such as North America GR-303, international market, thereby prepares the voice service that is used for transmitting on PSTN.
The problem that architecture is relevant is the normally equipment of a costliness of voice gateway therewith, has therefore limited the service provider and has been the ability of new user's introduction through the voice service of DSL.Therefore, in this field, there is a kind of demand, the speech through DSL promptly is provided, and need not offer the expensive voice gateway of some place employing of PSTN in the DSL voice service.
Summary of the invention
The invention solves above-mentioned with provide through the voice service of DSL relevant problem and other problem, be appreciated that these problems by reading and studying following description.Embodiments of the invention will be combined in through the voice gateway module of DSL in the network equipment relevant with the DSL business is provided, thereby voice data is become the TDM form from the ATM format conversion.Advantageously, in some embodiments of the invention, outside the voice gateway module of DSL, the network equipment also utilizes existing circuit, thereby for traditional PSTN equipment, prepare data from ATM cell as GR-303 processor and DS0 matrix or the circuit that is suitable for another standard.
Specifically, one exemplary embodiment of the present invention provide a kind of telecommunication system.This telecommunication system comprises the access transmission network network with the interface that can be coupled to public switch telephone network.Telecommunication system also comprises the digital loop carrier that at least one and access transmission network network are coupled, and it provides Digital Subscriber Line (xDSL) business for a plurality of users.Described at least one digital loop carrier comprises the embedded gateway module, and this module is changed between packet format and time division multiplexing form, so that the speech transmissions between Digital Subscriber Line and the public switch telephone network.
