Analisis Continuity of Service (CoS) Jaringan Trunk Serat Optik Berbasis Synchronous Digital Hierarchy (Studi Kasus PT Telkom Indonesia Medan)

Abstract

Synchronous Digital Hierarchy (SDH) is a multiplexing on a trunk network or optical telecommunications backbone. The old multiplexing system is Plesiochronous Digital Hierarchy (PDH) working with a maximum clock pulse at each switching node, while SDH uses a pointer to mark the start of the payload. The pointer value affects the voltage phase at the network endpoint. Another advantage of SDH is its self-healing nature and good multiplexing management. In this study, an analysis of CoS (Continuity of Service) on the trunk that connects Arnet Medan Centrum (MDNC) with Pulo Brayan (PBR) of PT Telkom Indonesia was carried out. CoS analysis is based on the number of disturbances that occur in the trunk connecting the two central. Based on the data and analysis results, it is found that the CoS of the trunk or backbone network from the two locations is 99.995054% for Medan Centrum (MDNC) and 99.999401% for Pulo Brayan (PBR), this value is an indication that the trunk network is in a good performance condition.
