SS7/IP networks probe alternatives: integrated system increases overall reliability. (Testing and Diagnostics).With technology advances and network expansions, telecom munications solution providers are tested to effectively monitor signaling system 7 (SS7) and Internet telephony Another term for IP telephony and VoIP. In the late 1990s, some people made a distinction between Internet Telephony and VoIP: Internet telephony referred to voice over the public Internet, while VoIP referred to voice over private IP networks.

In addition, operators confront configuration mismatches between their networks and monitoring systems. These mismatches occur as operators modify their networks by adding and removing links and nodes. The result is a monitoring system that is not doing what it was intended to do--monitor the entire network. Further, as traditional monitoring systems increasingly are used to host business-intelligence applications, reliability of the probed architecture comes into question.
A need has emerged for converged equipment with smaller footprints, for products that provide multiple functions. The fewer vendors, products and interfaces staff has to maintain, the better. In addition, network operations personnel need reliable, easy-to-use tools to help them troubleshoot To find out why something does not work and to fix the problem. Troubleshooting a computer often requires determining whether the problem is due to malfunctioning hardware or buggy or out-of-date software. See debug. problems and resolve issues fast.
A new premise supposes that a probeless architecture can be used to capture data in SS7 and IP networks for use in monitoring and business applications. In the new architecture, probes are eliminated, and functions are integrated onto other network platforms. By physically removing the probes and retaining the monitoring platform, the functions remain intact.
The new premise removes all cabling and auxiliary equipment Noun 1. auxiliary equipment - electronic equipment not in direct communication (or under the control of) the central processing unit
off-line equipment for timing, muxing and other tasks, which typically are associated with a probe-based architecture. Physical tapping on an external link is no longer necessary, as existing network platforms are enhanced to provide the message-capture function and pass the data off for processing.
With an integrated system, the ability to monitor the network is possible even from the initial deployment of the network. Data is passed internally from the network equipment to the monitoring system, thus removing the need to externally tap onto the links.
Furthermore, the probeless architecture eliminates the extra administration required for probe-based solutions, because integrated platforms allow data to be passed between systems and enable configuration information sharing See data conferencing. between platforms. A private path exists between the network equipment and the monitoring system to pass message data and configuration details. As the network is expanded or modified, the changes are incorporated into the network equipment and propagated automatically to the monitoring component. The operator no longer has separate systems to configure or a monitoring system that is out of sync Out of Sync: A Memoir is the upcoming autobiography of American pop singer Lance Bass, set to be published on October 23, 2007. It features an introduction by Marc Eliot, a New York Times with the actual network.
Finally, in the new scenario, the platform used for network equipment is the same equipment that provides the data for the monitoring system, making the critical data needed for business-intelligence applications more readily available.
Currently ill the SS7 network, call data is retrieved from actual switches, a process with a number of flaws. First, that data cannot be retrieved in real time. Additionally, there is no centralized cen·tral·ize

Operators have been changing their focus to the use of monitoring systems as a means of accessing this data, which are then used to feed business-intelligence applications, such as fraud detection, billing, billing verification and quality of service. The associated revenue tied to these applications means that the typical single-threaded monitoring platform is no longer acceptable. Instead, availability of data becomes critical.
