CLI CHECKING

The Benefits

• Central real schedule of all tests avoiding test conflicts. No "busy agent" situation – calls are planned conflict free instead of blind shots”
• Synchronization between call generator and probe, measuring accurate call setup times
• Additionally Post-Dial-Delay and Pre-Charging Detection delivered
• Fix network (ISDN and POTS) destinations possible, not only mobile operators
• No call duration (call attempts only), saving on call costs and hiding test activity from the invoice of carrier partners
• No needs for administration, maintenance, debugging of system
• More QoS, additional services and future focus on SIP
• Integration capabilities into VoicePilot (Ascom) , iXTools (Telarix)

Objectives

In order to optimize the route selection, operators need to be able to measure the quality of service of each interconnection route, by measuring the CLI success rate for calls made from their network to external networks. Operators want to check whether the Service Level Agreements signed with its interconnection partners are fulfilled or not. A simple and effective way to have a good estimation of the Quality of Service offered by the interconnection carriers is to check if the CLI is transmitted to the target parties for a sample of detection calls performed on a regular basis. Carriers are looking for a managed service that would make calls to various destination networks using predefined routes, check the CLI on the receiving party as well as report on the CLI successful rate for each route/destination.

Core function of Ascoms CLI Solution is the managed service for monitoring technical quality of telco services. The heart of the infrastructure is based on a set of local units. The provided service addresses service assurance needs through the generation of transactions and the computation of Key Performance Indicators (KPI) about quality of service. Monitoring is performed with the end-to-end perspective and optional alarms are generated by the service if a threshold is exceeded concerning countries, routes, and services. Clients can troubleshoot problems by requesting ad-hoc calls on top of running call campaigns. The provided service requires no technical configuration activities by the client because the Local Units, systems and reports are entirely configured and managed by the back-office of the service provider team. From the client point of view, the use of the service is performed through the management website and by email.
