November 27, 2010 Ottawa D-STAR Symposium by D-STAR DD mode (High Speed Digital Data) Ying Hum (VA3YH)

2Specification High Speed data stream only In this mode, the voice signal is dropped and the packets are dedicated completely to digital data. Bandwidth kHz Baud rate 128 K bps Effective rate ~ 90 K bps Data Format – 8 bits Data Interface – ethernet bridge

3 Setup - Hardware ID-1 Computer Router - optional

4 Setup - Network 10.x.x.x IP for each registered user – default gateway Transparent to user. Just like an ethernet connection.

5Adminstration Standard D-Star gateway registration. Need IP address information for network setup NO DHCP assignment, static IP

6 Network Access Just like regular ethernet connection. Open for now

7Authentication No authentication Netreg is one possibility

8 Discussion Firewall rule ? Network sharing. Emergency application.
