Description

Integrated Service Module

The present invention relates to an integrated service module that performs subscriber-side processing of data and voice received from a VoDSL gateway, and more specifically, accommodates a voice processing unit received by AAL2, a data processing unit received by AAL5, and an IP gateway processing unit. The present invention relates to a terminal device of a complex subscriber terminal.

Conventionally, subscribers are provided to users through a telephone, a telephone system as a private exchange that provides a variety of services required for office automation, a modem, and an integrated access device (IAD) supporting an application that combines data and voice. Has been provided.

However, the use of individual equipment for each service as described above has a disadvantage in that it is cumbersome to manage each equipment. The existing integrated access equipment (IAD) is composed of a data processing unit of AAL5 and a voice processing unit of AAL2. However, since there is no internal call processing function for voice, there is a disadvantage in that an internal call processing must also go through an exchange that performs call processing.

On the other hand, the use of the Internet, IP telephony, VPNs, and mobile networking infrastructure technologies are increasing the demand for end-users at all levels to access applications and huge amounts of information over the network.

Therefore, integrating such conventional individual equipment into one enables high-speed data communication as well as general telephone service through one equipment, which can reduce the cost of implementing conventional individual equipment and maximize the efficiency of the equipment. It will improve the economics of service providers.

Accordingly, the present invention is to solve all the disadvantages and problems pointed out in the conventional subscriber-end terminal device as described above, and provides voice and data services to one subscriber-end terminal by integrating each component of the subscriber network into one. It provides additional service such as internal call processing function for voice and VPN through IP network, and provides data service through 10 / 100Base-T wired LAN or wireless LAN to internal subscribers. It is the purpose of the present invention to achieve.
