TSP Solution Telco RCA

Telco RCA is a TSP DATA solution developed for alarms handling and outages of telecommunication circuits realized by different technologies and these outages are analyzed based on the inventory data and determine the primary causes (Root Cause) and dependencies of alarms on a specific root cause. It uses customers’ data to determine for each root cause the customer services affected by that outage. This reduces the number of alarms that monitoring center operators have to attend to and also allows affected customers to be notified of their service outage before they find out themselves.

Technology support

For alarm collection and presentation, our solution uses the IBM Tivoli Netcool system, which is used in monitoring centers by most telecommunications operators in the world. This system supports the collection of alarms, from all commonly used Telco systems of various technologies, from DWDM, SDH, PDH, L2, radio, to 64k telephone circuits. In the event that support for a particular system is not available, we are able to prepare our own alarm collection system as part of the implementation of our solution.

The IBM Tivoli Netcool system is part of the delivered solution.

Inventory data

Inventory data, which our solution uses, is saved in an internal database. Data import from the ISP’s is included in the implementation. Client data can either be imported into the system’s internal database or it can use the ISP’s interface.

Circuit hierarchy and redundancy

A telecommunications circuit delivered as a service to a customer consists of parts implemented using different technologies, while some parts may be shared by multiple circuits for different customers. This hierarchy of circuits is described in the inventory data and is the basis for both root cause analysis and generation of affected customer services.

Some telecommunication circuits use redundancy to improve reliability. Our solution can handle the following types of redundancy:

main/protect path – mainly used in SDH networks

subnetwork (full mesh) – used in  L2 and IP networks

port redundancy


redundancy of phone prefixes and trunk groups
