ISDN pricing
4 sites have usage (/min) charges & $30/mo fixed
3 sites have fixed monthly costs of $35-90
2 sites have cost/call & $50-60/mo fixed
Break even points depend on $/min which is usually dependent on distance and # hours/mo
- $0.01/mo for 50 hr/mo = $30 + $30/mo fixed = $60/mo
- almost always pays to get unmetered for non local users (~ $0.05/min)
So xDSL especially interesting in areas where unmetered ISDN is not available
