Alternate Service Providers • Infrastructure Little legacy infrastructure in new market opportunity areas Deploy fiber along sweet spot (commercial) areas to create regional networks Believe they can recycle legacy copper for xDSL better and faster than ILECs Aggregate and hand off services to ILECs—IXCs and ISPs 1502 0942_05F9_c1

Alternate Service Providers • Characteristics Gain market share Compete with traditional last mile providers—use new technologies which lower the cost of services—erode ILEC customer base How can I obtain the most new subscribers in the shortest time frame?
