ABSTRACT:
The modem of this invention overcomes problems associated with use in a wireless radio frequency communications channel. This modem provides a data carrier detection (DCD) function for associated data terminal equipment even though a transmission carrier or tone is not used. Provision is also made for communicating with data terminal equipment operating at a substantially lower data rate than the modem data rate without requiring a reduction in the modem data rate.
