Abstract
A method of operating a captioned telephone comprising the steps of dialing a telephone number to a relay gateway, connecting to the gateway over a communication network, performing a test to assess communication network quality, based on the test results, setting up the captioned telephone to operate in at least one of a first mode and a second mode wherein each of the first and second modes is one of (i) a PSTN mode in which data is communicated between the captioned telephone and the relay gateway via analog transmission and (ii) an IP mode in which data is communicated between the captioned telephone and the relay gateway via the Internet.
Claims20
A method for configuring a captioned device used by an assisted user (AU) during a call with a hearing user (HU) where the HU uses an HU device during the communication, the captioned device including a first communication link and a second communication link, the method comprising the steps of:
- during a commissioning procedure:
- upon determining that the first communication link is connected to a network for communication, configuring the captioned device for two line operation wherein the captioned device receives the HU voice signal via the second communication link, transmits the HU voice signal to the relay via the first communication link, and receives captions corresponding to the HU voice signal from the relay via the first link;
- and
- upon determining that the first communication link is not connected to a network for communication, configuring the captioned device for one line operation wherein the captioned device receives the HU voice signal and captions corresponding to the HU voice signal from the relay via the second link.
A method for configuring a captioned device used by an assisted user (AU) during a call with a hearing user (HU) where the HU uses an HU device during the communication, the method comprising the steps of:
- during a commissioning procedure:
- upon determining that the first communication link is connected to a network for communication, configuring the captioned device for packet switched communication during communication sessions with HU devices;
- and
- upon determining that the first communication link is not connected to a network for communication, configuring the captioned device for analog communication during communication sessions with HU devices.
A method for configuring a captioned device used by an assisted user (AU) during a call with a hearing user (HU) where the HU uses an HU device during the communication, the captioned device including a first communication link and a second communication link, the method comprising the steps of:
- during a commissioning procedure:
- upon determining that the first communication link is connected to a network for communication, configuring the captioned device for two line operation wherein the captioned device receives packet switched HU voice signal via the second communication link, transmits the HU voice signal to the relay via the first communication link, and receives packet switched captions corresponding to the HU voice signal from the relay via the first link;
- and
- upon determining that the first communication link is not connected to a network for communication, configuring the captioned device for one line operation wherein the captioned device receives the analog HU voice signal and captions corresponding to the HU voice signal from the relay via the second link.
