1. Technical & Support Specifications
VinTALK’s redundant Class IV IP-PBX call platform is co-located at the Time Warner Telecom co-
location facility in San Diego, California. This state-of-the-art facility houses VinTALK’s IP soft
switching equipment and the network interconnections over which we deliver high quality voice
services to our customers.
It is this network infrastructure that allows VinTALK to deliver outstanding telecommunications
services.
The VinTALK network includes:
• Connection of high-speed T-1 lines from our customers to our network
• Voice switches that process all inbound and outbound calls
- All calls on the VinTALK network are free to our customers (see min. allotment)
- Local calls to customers on other operator networks, such as Qwest, Verizon,
BroadVox, MCI and Global Crossing are delivered over the Public Switched
Telephone Network (PSTN) and are also free to our customers.
- Long Distance and International calls are also completed over the Vinculum IP
network at lower rates than any domestic or international provider.
• Interconnection to the Public Switched Telephone Network for voice traffic
• Interconnection to the Public and Private Internet for data traffic
Key infrastructure components at the VinTALK data center include:
Redundancy of Power and Air-Conditioning
• N+1 redundancy on all power systems ensure that failure in one area will not
interrupt service at any level.
• Dual power circuits in each cage provide redundancy against failure of power within
the lines running to the racks
• Battery power and UPS supply interruption-free fail-over power for at least 120
minutes with the facility at full capacity
• Power generators are fully operational within 15 seconds. Diesel in the generators
will allow the facility to operate for 48 hours and the facility has contracts with multiple
local diesel providers to power the facility indefinitely
• Air temperature and humidity is kept at a constant level throughout the facility to
prevent damage to equipment and switches. All areas are kept at 70(+/-2) degrees F
and 30-60% relative humidity.
