Abstract: This paper analyzes adaptive clock methods for circuit emulation service over packet switch network, describes adaptive clock methods based on jitter buffer, and proposes a fast adaptive clock method based on jitter buffer. The method is contrasted with the present congener methods. A kind of simulation device is designed and a test platform is set up to test. Experimental results show that the improved method is effective.

Key words: clock recovery, jitter buffer, adaptive

摘要： 分析了分组网传送TDM技术中的自适应时钟方法，描述现有的基于去抖缓冲区填充级的自适应时钟方法，提出一种基于去抖缓冲区的快速锁定的自适应时钟方法，比较快速锁定方法和传统的基于填充级方法，设计和建立硬件设备和评测平台。测试表明了该改进算法的有效性。
