Diseño y Formulación del Manual de Operaciones y Mantenimiento para el equipo SDH SMS-2500A de la marca NEC.

Abstract

Network (RGT), has taken the engineers of the ICE (Costa Rican Institute of Electricity) to worry for the correct knowledge and the access, that the people involved in giving maintenance to the equipment, have to the most commonly used information concerning the operation of the equipment installed. It is the Tactical Business Unit (UEN) of Network Management and Maintenance (GRM), the one in charge of taking care for the right development and performance of such network, in addition with the research for new methods that guarantee easier management for the RGT. One of the equipment that is commonly found inside the Network is the NEC Add Drop Multiplexer SMS-2500A. Because of the characteristics of high bandwidth and complexity of such equipment, it is essential that the Instruction Guide, that describe the typical operation and maintenance routines, would be as easy to understand and fast to access as possible, in order to avoid interruptions in the data transmission that will cause time and money losses. That is why the Operation and Maintenance Instruction Manual for the SMS- 2500A developed, takes concern in all of the functional and theoretical issues of such equipment, in addition to the interpretation of alarms and transmission errors, and the common solutions to this problems. The manual has been developed with a pragmatic point of view to allow the easy comprehension of all the matters developed in it. The Manual also considers the main recommendations made by the ITU-T and how they were developed by the Nippon Electronic Company in making the SMS- 2500A. The first chapter is an introduction to the SDH and PDH transmission systems to obtain a better understanding of theoretical terms for further analysis.
