G2 Gateway Software
With the GLOBAL growth of D-STAR, we have gathered a wish list of improvements from you, the System Operators. Today, we announce the upcoming release of G2 for the US market!
Improvements
- Web browser-based (CGI) user interface
- Gateway registration request system
- User information management
- Individual Edit via web browser
- Introduce Relational Database management system
- Individual systems use DHCP
- Trust server requires static IP
- Data separate from Application
- Enables data to be used for other applications
- False Entries eliminated from Database
- Divert Gateway Trust Server if system crash (Static IP Required)
- Multi-cast
- One port per system, up to 10 systems
With the upcoming release of the G2 Gateway software, the Gateway Software administrator course is suspended and not required for the G2 software. While we have offered the first generation for system owners at no charge, this will not be the case for the G2 version. Starting April 1, 2008, the G2 software will be available for sale. Contact your favorite dealer for pricing information.
NOTE: The original gateway software package is NOT compatible with the new G2 software.

*Measure typical speed (thruput) using with a line speed test site, etc.
<Maximum through put calculation>
The following effective speed is necessary for each operating mode.
DV mode: 30 kbps/connection
DD mode: 180 kbps/connection•
Example: When connecting three digi-tal voice (multicast operation) and one data repeater;
DV mode: multicast (max. 10 areas)
30 kbps × 10 areas × 3 port = 900 kbps
DD mode: one port
180 kbps
Required maximum effective speed:
900 kbps + 180 kbps = 1080kbps
Fixed IP address (for Trust Server only)
