    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.

    Abstract translation: 用于听力障碍者的电话中继器的语音桥被构造成将语音数据传送到和/或从能够说话或听到语音的用户。 语音桥能够在一对电话线路之间通过语音通信,同时排除数据载波TDD信号通过。 几种方法可以实现TDD信号排除。 还包括隐私选项,以排除中继站操作员在不需要操作员的帮助时,不要对会话的部分进行监听。
