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

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

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
