1. In-Class Example (Incremental Traffic Carried )
New proposed trunk dimensioning criteria: “Each trunk in a group must earn enough revenue to pay for itself based on its carried traffic in the 3 busiest hours over 250 business days of the year.”
Revenue = $ 0.12 / minute in use
Annual cost = $1890
Assuming A=10 E in the busiest 3-hour period and assuming a direct trunk group with no overflow:
Find # trunks under new criteria
What is the blocking?
