Application specific features set the MBT9600 Four Modem apart from the conventional
high speed modems. Its compact size and ease of installation make the MBT9600 an ideal,
low cost alternative to conventional audio tone teleprotection systems.
The circuitry is
ideally suited for use over private networks such as conventional voice channels over
analog microwave.
The MBT9600 is also suitable for application in other voice frequency systems which require environmentally hardened, dedicated four wire modems. The MBT9600 meets or exceeds all applicable ANSI/IEEE and IEC standards.
FEATURES & BENEFITS:
- Compact - mounts directly onto DB-9 connectors
- Serial port powered - no external power supplies
- Auto configuring
- Fast retrain times
- Low Absolute 1 data delays
- No user set-up required
