Consider the use of Zenulta’s Enterprise Correlation Solution had it been available and in use at the time of the underground fire in Manchester (more)
What happened?
On the 29th March, 2004, a serious fire broke out in an underground tunnel located in Manchester. Contained within the tunnel were 24 large fibre optic cables, carrying Terabytes of traffic for many companies, including several large mobile telecommunication trunk connections.
Affect on operations:
Thousands of alarms would have suddenly been produced by:-
- 1000s of Basestation sites (BTSs and Node Bs)
- 100s of site controllers (BSCs and GGSNs)
- 100s of exchanges (MSCs and SGSNs)
- 1000s of transmission elements (those controlling DWDM, SDH, PDH, IP etc.)
- 1000,000s of lower link order alarms due the very high order multiplexing being carried by these major trunk arteries
It would be immediately obvious that ‘something big’ has happened, but due to the volume of information it would not be clear as to what.
Immediate action:
Identify the problem root cause, then ‘safely’ re-root the critical revenue bearing traffic (such as international calls) away from the Manchester area.
Why would correlation have been important?
Correlation would have immediately highlighted which ‘Highly Multiplexed’ transmission trunks had disappeared. The scale of the problem was so big that even the resilient routes were affected. Therefore, as the problem is made clear, the operators don’t waste precious time re-routing traffic into the same failed area. Millions of pounds can be saved by re-routing your higher revenue traffic over lower revenue roots.
Note: One of the scenarios Zenulta is deploying at Turkcell covers this very area.
“All correlations will be built and maintained in a centrally controlled "Zenulta" library, so that customers will be able to buy tried and tested scenarios already proven in other telco networks. Combined with the flexibility of our CrossTalk OSS/J adaptor, this ensures a quick and successful delivery which endorses our reputation with our end customers.”
