1. The digital switches industry has a major impact on the I-way.

2. A digital switching device in telecommunications for routing lines.

3. The innovation of this paper design digital switching supply instead of present linear supply. It is smaller size, the stability and working efficiency has been raised.

4. Algorithms for fault detection and diagnosis of T-S-T digital switching networks are devised in the paper.

5. The Toll Digital Switching System can provide various features and accommodate thousands of trunks.

6. This a long time before I do a digital switching system.

7. With the development of microelectronics technology, the digital switching power supply design has become a research hotspot.

8. A network that uses both digital transmission and digital switching.

9. With rapidly growing demand in high-frequency digital modularization power supply system, it's significative to study on high-frequency digital switching mode power supply.

9.

10. Broadband Digital Symmetrical Cable: Conform to the standard:YD/T818. Usage:Mainly used for connection between digital switching equipments and Broadband Networks.

11. The result shows that the all-optical arc-shape wave-guide switching has low switching power, digital switching feature, and good prospects for the application.

12. Using a constant biasing current and a reduced output logic swing, current-steering logic avoids the large digital switching noise of conventional static CMOS logic.

13. In this paper, a quick and practical fault diagnosing algorithm for the Space-Division digital switching network of SPC switching system is proposed.
