SoftSwitch Hardware
- Cluster of IBM
within an IBM BladeCenterT enabling "Power-on-Demand" by just adding
more Intel CPU
- Redundant servers with redundant CPU, hot swap and redundant
hard drives
- Carrier-grade shelf with redundant back plane, hot swap and redundant power, cooling, GigEN switches and management modules
- 105-250V AC, -48V DC, 1300W
I/O Boards
- PTG: Designed to fit inside the IBM BladeCenterT. Converts 63 E1s (SDH) to as many VoIP channels. Scalable DSP power.
- RTG: Pizza-box remote gateway managed by the HVS softswitch over the IP network. Converts 8 or 16 E1s (copper) to as many VoIP channels (fiber or copper Ethernet). Scalable DSP power.
