Description of the invention (present ( Please read the precautions on the back before filling this page) Interface of the telephone line in the heart office. DAA 1 0 7 electrically isolates the rest of the modem 100 from the telephone line. For example, DAA 1 0 7 provides galvanic isolation to avoid Voltage surges or transient voltages originating from modems 1000 produce deleterious effects on telephone network 108. Electrical isolation also brings potential problems related to the difference in operating voltage between telephone lines and modems. More specifically, the telephone line voltage may vary widely in a given network and often exceeds the operating voltage of the modem 100. In addition to electrical isolation, D A A 1 0 7 often provides a variety of signals, such as ring signals for modems 100. For the next generation of modems, which are printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the controller-less modem 1 1 10 is introduced, which includes the modem-side bus interface 1 1 4, DS P 1 1 6 and DAA 1 1 7 , Without a controller, for use to enable the host 1 1 1 to communicate through 1 1 8. In this design, a host controller (not shown) residing in the host 1 1 1 via the host-side bus interface 1 1 2 to control the controller-less modem 丨 1 〇, which can be passed through the host bus 1 1 3 is connected to the modem-side bus interface 1 1 4. D S P 1 1 6 and D A A 1 1 7 individually perform functions similar to D S P 1 0 6 and D A A 1 0 7. Coming to a more modern modem, the software modem 1 2 0 contains D A A 1 2 7 but no controller or D SP for use to enable the host 1 2 1 to communicate via the telephone network 1 2 8. According to the software modem design, a host controller (not shown) residing in the host 1 2 1 provides the DS P function and further controls the software modem 1 2 0 through the host-side bus interface 1 2 2. The host bus 1 2 3 is connected to this paper. The national standard (CNS) A4 specification (210X297 mm) -6- 1221363 A7 B7 V.

(Please read the notes on the back before filling out this page.) However, these existing modem architectures have many disadvantages, inefficiencies and excessive costs. When these modems were proposed by management agencies (which have established Standards and rules) when authorizing and permitting connection of subscriber equipment (such as modems) to the telephone network. The accreditation process is used to confirm compliance with telephone standards and regulations in various countries to avoid damage to the telephone network and to mitigate interference with other equipment that is also connected to the telephone network. However, the accreditation process, which often presents difficult design challenges, can be lengthy and cause excessive costs for the applicant. For example, global recognition typically takes 6 to 12 months and can cost between $ 100,000 and $ 200,000. Therefore, modems are recognized as a major source of cost, delay, and engineering burden, which must be borne by the modem manufacturer for each novel modem design. Printed by the Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs Refer to Figure 1B, which shows the evolution block diagram of various conventional hosts or computer connectors / busbars for modem communication. Initially, desktop computers were provided with a serial interface, such as the RS-232 serial bus (a standard recommended by TI / EA) 1 30, which later evolved into a universal serial bus (USB). R S-2 3 2 serial bus 1 3 0 uses a connector of 2 5 pin D Β-2 5 or 9 pin D Β-9. Next, the industry standard structure (ISA) bus 1 31 was introduced with various form factors to function as an expansion bus commonly used in personal computers. The I S A bus 1 3 1 can accept plug-in boards that control peripheral devices such as modems. As the next generation of personal computer bus, this paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) 1221363

PCI bus 1 3 2 provides a high-speed data path between the host processor and peripheral devices such as modem devices. There are usually three or four PCI slots on a given motherboard. A more recent The personal computer bus is an audio / modem riser (AMR) bus 1 3 3, which supports add-in cards to insert its motherboard containing audio and / or modem circuits. The AMR bus is a 4 6-pin bus , Which provides a digital interface between the card and the motherboard. The AMR bus has evolved into a communication and network riser (CNR) bus (which has an interface with 30 pins) and an advanced communication riser (ACR) bus (It has a 10-pin interface.) CNR and ACR provide additional support, such as LAN, DSL, or Ethernet interface. Similar personal computer buses have been introduced into notebook computers, such as those with Interface interface ISA bus 1 4 0, Personal Computer Memory Card International Association (PCMCIA) bus 1 4 1, Mini PCI bus 1 4 2 (similar to PCI bus 1 2 2), and mobile product card bus (MDC) 1 4 3 (similar to AMR bus 1 3 3).

Traditionally, DAA s has been implemented in analog modems (such as modems 100) to become the matching parts of transformers, relays, opto-isolators and discrete components. However, in order to reduce high costs, power consumption and traditional DAA s related Space, the DAA s was designed to be implemented in silicon, which resulted in silicon DAA s. In the early days, silicon d AA s relied on the transfer of analog signals across an isolation shield and still required many discrete components. However, silicon DAA design Utilizing an integrated codec to transmit digital signals across capacitors to reduce costs, power consumption, and space. For example, US Patent No. 6 Figure 3 (approved on February 26, 2002) (which is incorporated into this application for ease of reference) of 3 5 1, 5 3 0 (approved for reference) illustrates an exemplary silicon DAA design. The DAA includes a digital isolation shield that is attached to One end is coupled to a system-side circuit and the other end is coupled to a line-side circuit. The line-side circuit includes a digital isolation shield interface and a codec, and is connected to a telephone line. At the same time, the system-side circuit includes a digital isolation The shield interface and a host interface are connected to a host through a connector. However, today's silicon DAA designs still cannot isolate host-side components and DAA. Therefore, the gaps and extensions of DAA components and other components must still be designed It is valued in the process, it requires special knowledge and causes extra costs.
