Circuit Switched Data Services (CSDS) allow agencies to use regular phone lines to transmit data through synchronous, full-duplex, digital, circuit-switched networks at data rates up to DS1, including integral multiples of DS0 data rates to on-net and off-net locations.
- Connectivity to the public phone network
- Dial-in, toll-free numbers for off-net location – authorization required
- User-to-user signaling via ISDN D-channel
- Performance reports – availability, post-dial delay, grade of service
