Abstract

Method, system, and computer program product example embodiments of the invention are disclosed to provide multi-network secure video teleconferencing (VTC) for VTC endpoints. The embodiments of the invention include a sequencer that controls the sequence of operations when moving a video teleconferencing terminal between secure networks. The sequencer receives commands to initiate the operation from an initiator, such as a user-initiated button press from a control console or a user-initiated request from an Internet interface, or for a scheduled operation from a scheduling interface. The sequencer then issues commands to a secure database of terminal configuration data and a control isolator to both transfer a video teleconferencing terminal to a new secure network to begin a conference and to remove a video teleconferencing terminal from a secure network to end a conference.

Claims

1. A method, comprising:

receiving in a sequencer, a message from an initiator identifying a video teleconferencing terminal needs to be removed from a secure network to end a conference;

if terminal configuration capture is enabled for the secure network, then sending by the sequencer, a message to a secure database of terminal configuration data, announcing that the video teleconferencing terminal will be taken offline, to enable making a backup copy of information in non-volatile memory of the video teleconferencing terminal;

sending by the sequencer, a command to a control isolator to power off a media converter connecting a secure network switch to the video teleconferencing terminal, to enable removing the video teleconferencing terminal from the secure network;

sending by the sequencer, a command to the video teleconferencing terminal, via the control isolator, to delete any information in non-volatile memory, thereby setting the video teleconferencing terminal back to a factory default state; and

sending by the sequencer, a command to the control isolator, to remove power from the video teleconferencing terminal, thereby removing any data in volatile memory.

2. The method of claim 1, further comprising:

causing resetting a codec in the video teleconferencing terminal back to a factory default state, and verifying that data cleaning of the codec was successful after the resetting.

3. The method of claim 1, further comprising:

sending by the sequencer, a command to the control isolator to display a message on a display device at or near the video teleconferencing terminal indicating that a classification is being changed.

4. An apparatus comprising:

at least one processor;

at least one memory including computer program code;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

receive in an apparatus, a message from an initiator identifying a video teleconferencing terminal needs to be removed from a secure network to end a conference;

if terminal configuration capture is enabled for the secure network, then send by the apparatus, a message to a secure database of terminal configuration data, announcing that the video teleconferencing terminal will be taken offline, to enable making a backup copy of information in non-volatile memory of the video teleconferencing terminal;

send by the apparatus, a command to a control isolator to power off a media converter connecting a secure network switch to the video teleconferencing terminal, to enable removing the video teleconferencing terminal from the secure network;

send by the apparatus, a command to the video teleconferencing terminal, via the control isolator, to delete any information in non-volatile memory, thereby setting the video teleconferencing terminal back to a factory default state; and

send by the apparatus, a command to the control isolator, to remove power from the video teleconferencing terminal, thereby removing any data in volatile memory.

5. The apparatus of claim 4 further comprising:

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

cause resetting a codec in the video teleconferencing terminal back to a factory default state, and verify that data cleaning of the codec was successful after the resetting.

6. The apparatus of claim 4, further comprising:

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

send by the sequencer, a command to the control isolator to display a message on a display device at or near the video teleconferencing terminal indicating that a classification is being changed.

7. A computer program product comprising computer executable program code recorded on a computer readable non-transitory storage medium, the computer executable program code, when executed by a computer processor, causing performance of the steps of:

receiving in a sequencer, a message from an initiator identifying a video teleconferencing terminal needs to be removed from a secure network to end a conference;

if terminal configuration capture is enabled for the secure network, then sending by the sequencer, a message to a secure database of terminal configuration data, announcing that the video teleconferencing terminal will be taken offline, to enable making a backup copy of information in non-volatile memory of the video teleconferencing terminal;

sending by the sequencer, a command to a control isolator to power off a media converter connecting a secure network switch to the video teleconferencing terminal, to enable removing the video teleconferencing terminal from the secure network;

sending by the sequencer, a command to the video teleconferencing terminal, via the control isolator, to delete any information in non-volatile memory, thereby setting the video teleconferencing terminal back to a factory default state; and

sending by the sequencer, a command to the control isolator, to remove power from the video teleconferencing terminal, thereby removing any data in volatile memory.

8. The computer program product of claim 7, further comprising computer executable program code recorded on a computer readable non-transitory storage medium, the computer executable program code, when executed by a computer processor, causing performance of the step of:

causing resetting a codec in the video teleconferencing terminal back to a factory default state, and verifying that data cleaning of the codec was successful after the resetting.

9. The computer program product of claim 7, further comprising computer executable program code recorded on a computer readable non-transitory storage medium, the computer executable program code, when executed by a computer processor, causing performance of the step of:

sending by the sequencer, a command to the control isolator to display a message on a display device at or near the video teleconferencing terminal indicating that a classification is being changed.
