[Features and effects] The present invention provides an effective channel transmission method and device for an ISDN multiplexing system. When compared with conventional technologies, it has the following advantages: 1 _Design an effective channel transmission method combined with the ISDN multiplexing system to improve the effective utilization of the IMS transmission channel, so that 1 T1 can provide 11 ISDNBRAU interface transmissions, and the same -1 T1 trunk is used. Under the circumstances, the capacity of the IMS system is increased by 1.375 times that of other systems. 2. The device provides alarm indication for monitoring the coded signal and signal quality on the T1 line. -10- This paper uses Chinese national standards again (CNS > A4 specification (2X 297)} (Please read the note on the back first to write this page) " Silk 444480 Λ, PA370444.TWU-11 / 11 V. Description of the invention (q) 3. The present invention has the advantages of low installation cost, simple maintenance, and saving wiring and maintenance costs between the user and the central office. 4. The present invention is similar to the ISDN extended service range and transmission distance. In terms of ISDN door number dispatching, it can meet customer and operation needs in a timely manner, and greatly contribute to the support of ISDN operations. 5. The invention breaks the monopoly of the same type of products by the original switch manufacturers and foreign communication vendors. The technology used to increase the capacity of the IMS transmission channel is completely mastered, and can be modified in the future when there are changes in the domestic ISDN agreement or transmission interface. 10 The detailed description above is a specific description of one of the feasible embodiments of the present invention. However, this embodiment is not intended to limit the patent scope of the present invention, and any equivalent implementation or change that does not depart from the technical spirit of the present invention should be included in the patent scope of this case. This case is not only an innovation in space thinking, but also can enhance the above-mentioned multiple effects compared to 15 existing devices. It should have fully met the requirements for novel and progressive statutory invention patents, apply in accordance with the law, and ask your office to approve this new patent application The case is inspired by inventions and creations, and it is a matter of ethics. -11-The paper Λ degree applies to the Chinese national standard (CNS > A4 specification (2 丨 0 X 297 mm)
