Nokia Siemens in next-gen technology deal in Russia

Nokia Siemens Networks is integrating Next Generation Network technology in the network of Russia’s largest fixed-network operator. Moscow City Telephone Network (MGTS) is investing in new network technology so it can connect new phone lines and offer speeds of up to 25 megabits a second for Internet access.

The existing infrastructure based on analog and digital exchanges and Time Division Multiplexing (TDM) will be replaced by IP softswitches and media gateways. In addition new access technology will be integrated into the network. Work on the network is to be completed by the end of 2011.

An essential requirement for MGTS was that the new NGN solution work seamlessly together with the existing TDM-based technology. Nokia Siemens Networks achieved this in the scope of the Converged Access solution with a uniform central management system for both technologies. Similarly, a comprehensive billing and monitoring system is provided.

Altogether, this solution enables a gradual transfer from the previous to the next generation network technology.

The new network technology will create the potential for additional revenue streams for MGTS. For example, the carrier will be able to offer online games and other multimedia services requiring broadband access. To enable this, MGTS has selected the access technology ADSL2+, which will be provided via an IP DSLAM (Digital Subscriber Line Access Multiplexer). This technology increases the maximum download data rate to 25 Mbit/s and makes it possible to transmit TV signals.

Moreover, the IP DSLAM can be used very flexibly; analog line cards for voice transmission and Ethernet or DSL cards can be used in a single chassis, saving the carrier money.

MGTS serves about 4.2 mln subscribers and runs 561 telephone exchanges. The public payphone network, MGTS’ component part, has 8,000 paystations in operation. It’s share of main phone numbers on the Moscow fixed communication market is 77.2%.
