Tier I Business Case
• Scenario One
• Upgrade from DS3 to OC3
• IOF costs $39K per OC3
• Request for 6 OC3s generates the
deployment of a new switch/router
• Scenario Two
• Eliminates new ATM Switch/Router
• Interworks traffic locally, minimizing
IOF costs
• Quantifiable Savings
• $569K per Central Office
• $56.9M per 100 Central Offices
• Frees up multiple DS3 ATM ports
and DS3 IOF facility
Scenario 1: Upgrade of 6 ASAMs in a CO using the
current strategy of ATM/SONET upgrades
6 IOF OC3s to ATM Switch (New Ring)
ATM Switch Cost
ERX Router
EF&I of ATM and Router
IOF for ATM to Router and Router to

Total Cost
$1,353,707
Scenario 2: Upgrade of 6 ASAMs in a CO using the
ADTRAN TA5000 for ATM/Ethernet Interworking
TA5000 equipped for 7 OC3s
EF&I of TA5000
1 IOF GE to Router and GE card at
Router
EF&I of Router
1 IOF OC3 to ATM Switch
ATM Switch 4-Port OC3 Card
IOF for Router to LCR
Total Cost
$784,366
Total Savings for Scenario 2
