ABSTRACT:
A voice bridge for a telephone relay for the hearing impaired is constructed so as to pass voice data to and/or from a user who is capable of either speaking or hearing voice. The voice bridge is capable of passing voice communication between a pair of telephone lines while excluding data carrier TDD signals from passage. Several methods are possible to achieve TDD signal exclusion. A privacy option is also included to exclude the relay station operator from overhearing parts of conversation when the operator's assistance is not required.
