infrastructure services and engineer systems, and we are working to
set up an information security complex for the data center, which will
mean expanding the functionality of the core monitoring system," says
Mikhail Krymskiy, Deputy General Director of OAO Uralsvyazinform. "We
plan to use the Netcool solution for monitoring of the complete
corporate data network, the main part of multi-service network, as
well as other technical networks and IT services. All of this will
enable our company to significantly increase the level of service
provided, raise control over business processes, and consequently,
improve the competitive power of OAO Uralsvyazinform on the market."
   "We are pleased that Micromuse's Netcool solutions are being used

   Sergey Dryagin, Deputy General Director of Open Technologies,
adds, "Uralsvyazinform was seeking a robust enterprise software
solution that could automate complex tasks such as fault management,
while still providing scalability, adaptability, data security and
visibility of the entire IT infrastructure and engineer systems.
