• Critical Customers– Hospitals/Public Safety/Gov’t Facilities/Universities/Broadcast Media– Linkage between customers and associated network elements
• Grade of Service– Escalating Expectations of society
• Paradigm Shift (wireless/wireline)– What is an acceptable level of risk?
• Regulatory/Zoning/Property Mgt issues– Restrictions in code or lease regarding generators– Access (safety concern)– Floor loading– Requirements differ for tech types (Wireline, wireless, VoIP)– Tariffed vs. non-tariffed providers
• Budget $$$– Business Case (cost of equip vs. revenue loss)– Cost of technology

• Design process for power plants– Role in telco network (Importance of site)
• Priority classes of sites (eg Hub Site vs. end cell)– Threat Assessment– Interdependencies (eg wireline backhaul)
• Robustness of network topology– Environmental factors
• Rural vs. urban location• Location within power grid (opportunity to work with pwr provider proactively)• Climate control• Proximity to disaster prone areas
• Coordination b/n Telco, Power Company, restoration coordinators– Proactive vs. reactive
• When/how do you build the relationships?– Mechanisms for coordination (elec co call center, acct rep, fire dept, State/Local EOC,
Federal agencies)– Escalation process to follow
• justification criteria– Ability of pwr company to map/DB critical sites
