Description

Access integrated board for accessing multiple services

[1] Technical field

[2] The present invention relates to the field of communications, and specifically relates to an access integrated board for accessing multiple services.

[3] Background of the invention

[4] As users' demand for telecommunication services increases, large-capacity, high-speed, high-quality integrated services (data, video, voice, multimedia, etc.) become the main direction of access network development. Therefore, improving the comprehensive access capability of integrated access equipment is an inevitable trend for the development of telecom equipment suppliers.

[5] The traditional integrated service access is mainly based on dial-up Internet access and ISDN access, and the development of broadband services is promoted.

ADSLs HDSL, ADSL2/2 VDSL/2 and other XDSL access. ISDN (Integrated Services Digital Network) access is still existing in private network construction and some intelligent networks due to its mature technology, high transmission quality, good service performance and high service reliability. More and more ISDN users are increasingly demanding broadband services.

[6] Most of the existing access networks provide broadband services such as ADSIJVDSL to ISDN access users in the manner shown in FIG. 1. FIG. 1 shows an ISDN user in a separate access mode according to the related art. Access card. That is, the broadband digital subscriber board is placed in a broadband cabinet, and the ISDN digital subscriber board is placed in a narrow-band cabinet. The broadband single-board subscriber line and the ISDN single-board subscriber line are integrated on the distribution frame to meet the needs of providing ISDN subscribers with broadband services and ISDN integrated access services.

[7] The inventor found in the process of implementing the present invention: The existing split access mode is completely isolated due to the broadband device and the narrowband device, so the network management and the user equipment maintenance need to be separately operated to provide network maintenance and service query. Bring a certain degree of inconvenience. ISDN access users need to smoothly upgrade to broadband services, and additional equipment such as cabinets and chassis are required, resulting in a significant increase in cost.

Another existing solution that can be used is the implementation scheme of ISDN digital COMBO (access integrated single board) board. The ISDN digital COMBO is mostly designed as a unit of ISDN and ADSL/VDSL, that is, in one board. Implement ISDN+ADSL

/VDSL access function, as shown in Fig. 2, Fig. 2 shows another ISDN digital subscriber unit in accordance with the related art, in which the wideband circuit portion and the narrowband circuit are separated from each other. The inventor found in the process of implementing the present invention: In the ISDN digital subscriber unit shown in FIG. 2, since ISDN and ADSL/VDSL are collectively fixed on one board, this causes great limitations, for example, when After the ISDN user needs to perform the broadband expansion service, if the number of ISDN users and the number of users who need to expand the bandwidth are not equal, the resources on the board will be wasted.

It can be seen that the user access card of the split access mode shown in FIG. 1 and the ISDN digital user integrated board shown in FIG. 2 have corresponding problems. Therefore, there is a need for a solution for an ISDN digital subscriber COMBO that addresses the problems in the related art described above.

In this implementation, the broadband internal and external tests are eliminated. The definition of each connector is the same as the definition in Figure 3. It can still realize the functions of independent board, inter-board COMBO and in-board COMBO.
