Recently I sat down to read an article from techtarget.com. The article was written by Paul Kirvan, a board member of the Business Continuity Institutes's US Chapter. He discussed some of what he believes are the best practices in ensuring reliability in an organizations voice/data network. When asked how do you ensure reliability in a voice/data network during a power outage he replied by saying that "a private voice/data network has a very good chance of being run over what might be called 'traditional' phone lines. He also adds that access from a local telephone company exchange to a company is most likely going to be over copper or fiber-optic facilities provided by the local telephone company. He believes that the likelihood of a telco-centered power outage small to none. He describes a few techniques one could incorportate to insure resillience. First he suggests installing a diversely-run local access network to a different local telco with no overlapping cables routes and manholes. Second, use free-space communications, such as point-to-point microwave to bypass the local loop. These two techniques along with others explained in the article will allow an organization to have better prepared for the storm.
When asked what kind of IT infrastructure is needed for a robust voice/data network he answer by suggesting that a fully-meshed network is an ideal configuration if money is not an object. He says that backing up power systems for all critical infrastructure hardware is essential and locating network equipment in secure equipment areas is also important.
It seems to me that ensuring reliability in voice and data networks are very important. It's also equally important to understand why.
