The report says Data centres provide the physical infrastructure for the virtual economy. They are at the heart of ‘on-demand’ hosted cloud computing services and a key asset for enterprise users in supporting business operations and providing real-time availability of a wide range of applications. Data centres provide highly secure and reliable facilities for mission-critical operations.
In looking to consolidate all critical ICT services into the data centre, CIOs have often been constrained by the limitations of the Public Switched Telephone Network (PSTN). Whilst their private voice network may bring modern centralised IP voice services to allow inter- and intra-company calling, calls made from the PSTN to their private networks have had to follow a fixed, geographically dispersed, delivery model – one that, until now, has been at odds with their data centre strategy.
This White Paper, Extending the role of the DataCentre, describes the drivers supporting the centralised delivery and management of PSTN voice services into the data centre. It explains the problems faced by large multi-sited organisations today and highlights how they can benefit by moving away from shared PSTN access infrastructure to a dedicated and direct connection with the PSTN.
It provides specific examples of how organisations have successfully extended the PSTN Core Network to the enterprise, which removes, rather than replaces, the PSTN Access Network. One of the user examples analyzed in the White Paper found that as the solution is rolled out to its 6,000 employees, savings of up to 40% on line rental and call charges are expected.
“Delivering voice services through the data centre rather through the local office, offers reduced costs, increased agility and resilience,” commented Steve Wallage, managing director of BroadGroup Consulting.
“Leading companies in areas such as finance and government are already pursuing such a direction, often as part of a broader Unified Communication strategy.”
