Jhamel uses Enterprise's telepresence unit to contact her brother, Gareb
A telepresence unit was a device which utilized telepresence to allow a person to safely control a vessel from a remote location. Telepathy was required to use a telepresence unit, which could transmit brain wave signals through many light years in space.
In 2154, the Romulans utilized a telepresence unit to control two Romulan drone ships from a command center on Romulus. The crew of Enterprise also created a telepresence unit to prevent the Romulans from continuing their attacks with the prototype drone ships. Though Commander T'Pol was unsuccessful in operating the unit, the Aenar Jhamel managed to control the device and was able to convince her brother, Gareb (who was controlling the drone ships), to stop the attacks.
