Satellite network

Satellite Network

  • Hub & spoke topology

    • E1 links to Miami

  • Independent of incumbent

  • Makes sense for emerging carrier

Network expansion

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

Problem statement

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


Submarine cable network

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

Linear network configuration

Linear Network Configuration

  • Star (Hubbing) bandwidth configuration

    • Flexibility in quickly assigning bandwidth per link

  • Mesh bandwidth configuration

    • Allows reuse of capacity
