Abstract

To provide economical BISDN service, with which integration process of many types of media is possible, it is necessary to construct a system with ground network and satellite network combined. The method for this type of transmission using satellite is TDMA that can provide services to many users in various area. However, the most difficult task to connect TDMA which uses synchronous method to ATM which uses asynchronous transfer mode is the deterioration of ATM transmission quality such as cell delay variation. Therefore, it is necessary to develop delay variation compensation method which can confront to the ATM. Efficient ways to use satellite links under the conditions such that maximum efficiency of the delay variation is limited under the required value, and the burst characteristic of transmission cell does not increase are being researched for translation between ATM and TDMA. This paper points out the problems when time stamp method, reviewed in ground network, is applied to the satellite links to compensate the delay variation. To solve the problems, discrete cell count method is introduced along with the calculation of transmission capacity and error rate. Also, from the observation of stability of the system and verification of reliability even when signal error occurred in the cell transmission timing information, the proposed compensation method appeared to be excellent.
