Phonoscope met the challenge last week to reinstate fiber-based opticEthernet connectivity for businesses and government agencies in the hoursand days following the powerful hurricane. Disaster recovery planningstarted early beginning with strategy meetings to review and updatePhonoscope's emergency procedures prior to the onset of the hurricaneseason. As Hurricane Ike loomed in the gulf, the network team began toexecute its strategy as early as the Thursday prior to landfall for thestorm. Hurricane Ike hit at daybreak on Saturday, September 13, with 100mph winds and immense rainfall.

Kurt Rushe, Network Operations Manager for Phonoscope, stated that,"Phonoscope's Network Operations Center personnel were continuouslyavailable through the duration of the storm and answered close to 3,000calls as Hurricane Ike approached and immediately following. As soon asthe storm passed through, Phonoscope's NOC, data, operations, and fieldpersonnel immediately began implementing restoration measures providing thespeediest restoration of service record of any utility in the affectedarea."

Phonoscope has provided Gigabit Ethernet LAN services to the Houston areaover the last decade and was presented with a critical challenge of rapidlyand efficiently delivering network services to those public safety,municipal, enterprise businesses, school districts, and universitiesadversely affected by the storm. At the peak of the outage, up to 700network devices were out of commission; however, in less than a week 90% ofcustomer services were restored.

"We were very pleased that following Hurricane Ike, everything came back upand online almost perfectly, once we had the benefit of power to thebuildings," said Robert Jacobs, Network Director for Phonoscope. "We had noreconfigurations lost from the many power cycles and hits that weexperienced with our switches. Further, we have even had several ofExtreme Networks' Summit® and BlackDiamond® Ethernet switches runningat a hot 62 Celsius, operating without air conditioning over fourconsecutive days following the storm, yet they have continued to deliver."

Phonoscope tackled the challenge of reinstating network services,everything from aggregation nodes to well over a thousand ExtremeNetworks® edge switches located in customer sites through the GreaterHouston area. Baytown was also hit hard by the storm, and Phonoscope wasable to rapidly power up network services for critical care medicalfacilities and other enterprise customers in that area. In some cases,the only form of voice communication available in the area was due to theIP network.

While some switches were damaged due to flood waters, Phonoscope airfreighted replacement devices and Summit X450 and Summit X250s which aresimple to reinstall. "What shined was the use of Extreme NetworksEPICenter® management software for switch configuration, giving us thecapability to make changes rapidly across the network for many clients,"said Jacobs. "A customer may have had just one flight of power, so entirenetworks and Layer 2 VLAN topologies were shifted on the fly to where theywould be best utilized."

"We have been honored to work with Phonoscope over the last decade and tohave assisted them to recover network services at such a critical timefollowing such a large storm last week," said Paul Hooper, chief marketingofficer for Extreme Networks. "This successful outcome is a testament tothe commitment of many professionals and the simplicity, flexibility andoverall resiliency of Ethernet networking."
