  1. Improved Flexibility & Economics by Transitioning from Satellite to Submarine Wayne Walters Director Market Development ECI Telecom Steve Battick Head of Carrier Services Digicel

  2. Satellite Network • Hub & spoke topology • E1 links to Miami • Independent of incumbent • Makes sense for emerging carrier Miami Guadeloupe Dominica Martinique St. Lucia Barbados St. Vincent Grenada Trinidad

  3. Intra-Island Traffic No satellite capacity required Intra-Island Inter-Island Rest of World

  4. Rest of the World Traffic Satellite link to tandem switch point Intra-Island Inter-Island Rest of World

  5. Island to Island Traffic Consumes twice satellite capacity Intra-Island Inter-Island Rest of World

  6. Network Expansion • Increased satellite capacity • Expensive • Add SDH radio link • Leverage satellite infrastructure • Lower cost alternative to satellite • Increases burden on satellite link for rest of world traffic • Add leased E1s via submarine • Expensive • Relieves some island to island traffic issues • Increases burden on satellite link for rest of world traffic Miami Guadeloupe Dominica Martinique St. Lucia Barbados St. Vincent Grenada Trinidad

  7. Problem Statement • Satellite network • Very practical for initial infrastructure requirements • Add on leased E1s & SDH radio • Manage several transport networks • But with success • Voice traffic growth • More island to island traffic • More rest of world traffic • Data service offerings • Higher bandwidth requirements but bursty • Network is expensive to expand & maintain

  8. Submarine Cable Network • Linear network • Flexible connectivity • Reuse of bandwidth • Indefeasible Rights of Use (IRUs) • Lease costs  Capital investment • Increased capacity • STM4 capacity (252 E1s) • Versus N x E1s • Increased flexibility • MSPP provides E1 grooming • Improved data support • Dual hubs • Miami & New York • Improved reliability New York Miami Guadeloupe Dominica Martinique St. Lucia Barbados St. Vincent Grenada Trinidad

  9. Linear Network Configuration • Star (Hubbing) bandwidth configuration • Flexibility in quickly assigning bandwidth per link • Mesh bandwidth configuration • Allows reuse of capacity
