System Level Analysis and Performance Evaluation of Soft Switch Network in PTCL South Region

Abstract

In this paper, we present a thorough research to analyze the performance of the soft switches of PTCL (Pakistan Telecommunication Company Limited) in south region by taking real values from the operational systems and ratio of fault occurrence in soft switches. The major issues and shortcomings related to hardware of soft switches, network build up and protocols of SS (Soft Switch) are discussed. Performance characteristics of two soft switches (Pak Capital SS Vendor-A and Marston Rd SS Vendor-B) on the basis of key parameters including, System over view, System architecture, Hardware, Network built-up are analyzed. All parameters are compared with PTA (Pakistan Telecommunication Authority) standards and suggestions are provided to remove single point of failure to achieve 24x7 services available for the customers of PTCL. The conclusion drawn out of the research works, and suggestions provided will pave a path to increase the efficiency of soft switches, enrich the operation of the system, reduces the fault occurrence and complete isolation of the MGs/MSAN/MSAGs, improve the availability of the PTCL services to its customers and will enhance the image of the company for its valuable customer
