8. Modem Pool Recommendations, Option 1 Reduce one Primary Rate Interface (PRI) circuit (24 lines) from each modem pool, respectively. –Advantages Reduce Costs ($14,630 annual savings). Minimum service level degradation. –Disadvantages Expensive to reinstall, if needed. Introduce busy signal to users (largest impact to student and staff users).

9. Modem Pool Recommendations, Option 2 Reduce PRI circuits by 14, introducing busy signal during peak hours (approx. 2-4 hrs.). –Advantages Reduce costs ($68,000 annual savings). –Disadvantages Significant busy signals during peak hours. Increase of complaint calls to Data Center and Network Operations Center Increase time to diagnose network problems. Expensive to reinstall, if needed.

11. Modem Pool Recommendations, Option 3 Consolidate all modem pools into one; reduce PRI circuits by 16; and remove 2 Cisco AS5200 and 2 Cisco AS5300 Access Servers. –Advantages Reduce costs ($91,000 annual savings). –Disadvantages Single point of failure for all dial-in customers. Severe increase in busy signals during peak hours. Significant increase of complaint calls to Data Center and Network Operations Center. Increase network troubleshooting complexity. Increase in third party vendor dependency (Pacific Bell). Expensive to reinstall, if needed.
