Network Expansion
Increased satellite capacityExpensive
Add SDH radio linkLeverage satellite infrastructureLower cost alternative to satelliteIncreases burden on satellite link for rest of world traffic
Add leased E1s via submarineExpensiveRelieves some island to island traffic issuesIncreases burden on satellite link for rest of world traffic
7
Problem Statement
Satellite networkVery practical for initial infrastructure requirements
Add on leased E1s & SDH radioManage several transport networks
But with successVoice traffic growth
More island to island trafficMore rest of world traffic
Data service offerings Higher bandwidth requirements but bursty
Network is expensive to expand & maintain

Submarine Cable Network
Linear networkFlexible connectivityReuse of bandwidth
Indefeasible Rights of Use (IRUs) Lease costs Capital investmentIncreased capacity
STM4 capacity (252 E1s)Versus N x E1s
Increased flexibilityMSPP provides E1 groomingImproved data support
Dual hubsMiami & New YorkImproved reliability
9
Linear Network Configuration
Star (Hubbing) bandwidth configurationFlexibility in quickly assigning bandwidth per link
Mesh bandwidth configurationAllows reuse of capacity
10
Flexible Submarine Network
Submarine cable operator provides STM1 groomingAddition of MSPP allows STM1, VC4, & VC12 groomingDynamic control of bandwidth via MSPP
Shift bandwidth with traffic demands
