A Study on Clock Recovery Algorithm for ATM AAL 1

ATM AAL 1을 위한 클럭 복원 알고리즘 연구

In this paper, we are proposed ATM AAL 1 source clock recovery methods for CBR service. The proposed method compute the difference between network clock level and the reference level by inspecting the variation of a buffer. Also it is the service clock recovery method that control local clock using the look-up table defined clock dividing rate of the difference in advance. It can be applicable to both SDH network and PDH network which has no common reference clock between its ends, it has an important mean in view of the internetworking between existing networks for the integrated service chased by B_ISDN.
