TABLE OF CONTENTS With fewer assets to power, softswitch uses less power. This translates into financial savings the service provider cannot ignore. A Class 4 configuration similar to that in Table 11-3 might draw 600 amps DC, as opposed to a comparable softswitch configuration that draws 24 amps DC. This translates into softswitch using only four percent of the power of Class 4. [12] These savings will be explored further in the net present value models at the end of this chapter.
| Class 4 | Softswitch | |
|---|---|---|
| Number of 7-foot racks for 36,000 DS0s | 13 | 1 |
| Cost per month per rack for power at 20 amps at $20/amp | $400 | $400 |
| Total per month | $5,200 | $400 |
| Total per year per location | $62,400 | $4,800 |
