Experiences in automating the testing of SS7 signalling transfer points

Tim Moors, Malathi Veeraraghavan, Zhifeng Tao, Xuan Zheng, Ramesh Badri
2002 Software engineering notes  
Service providers need to frequently test their Signalling Transfer Points (STPs), which switch SS7 messages, for both protocol conformance and interoperability.  ...  Signalling System 7 (SS7) is widely used for telephone signalling.  ...  The New York State office of Science, Technology and Academic Research also sponsored this project through the Center for Advanced Technology in Telecommunications at Polytechnic University.  ...

Experiences with concurrent TTCN for GSM/SS7 testing [chapter]

Elyane Prevot, Michel D'Hooge, Patrice Labbe
1996 Testing of Communicating Systems  
The introduction of concurrent TTCN reduced the testing specification complexity. This paper describes a practical experience with concurrent TTCN in the GSM environment.  ...  It demonstrates the importance of completeness in test purpose specification and the advantage of allocating substantial resources to both ATS development and ATS validation to ensure ATS quality.  ...  The authors would like to thank their colleagues Barbara Raither, Vincent Belalche (Trialog), and Bruno Chatras (France Telecom -CNET) for their useful comments during the elaboration of this paper.  ...

Heat-evolved microalgal symbionts increase coral bleaching tolerance

P. Buerger, C. Alvarez-Roa, C. W. Coppin, S. L. Pearce, L. J. Chakravarti, J. G. Oakeshott, O. R. Edwards, M. J. H. van Oppen
2020 Science Advances  
With the aim of enhancing coral bleaching tolerance, we evolved 10 clonal strains of a common coral microalgal endosymbiont at elevated temperatures (31°C) for 4 years in the laboratory.  ...  Although lower levels of secreted reactive oxygen species (ROS) accompanied thermal tolerance of the heat-evolved algae, reduced ROS secretion alone did not predict thermal tolerance in symbiosis.  ...  Funding: The research was funded by a CSIRO Research Office Postdoctoral Fellowship to P.B., CSIRO Land & Water, the University of Melbourne, Paul G.  ...

Technical Issues for IP-Based Telephony in Nigeria

A. A. Ojugo.
2013 International Journal of Wireless Communications and Mobile Computing  
Security PSTN became resistant to security attacks with the advent of SS7 out-of-band signaling. IP nets are more susceptible to attacks to address 3-issues: 1.  ...  Signaling/Trunking Gateway: Signaling gateway acts as a gateway between the call agent signaling and SS7 protocol-based PSTN, to provide the required signaling translation and a cross platform for  ...  Management related issues will hinge on a design that will motivate the overall architecture and act as a start point for protocol profiling and interoperability testing.  ...
