Om-Com

From Tardis Wiki, the free Doctor Who reference

Om-Com was a method of communication that could remotely connect to anything with a speaker-grill. It was used by the Chula.

The name is likely derived from some variation on "Omni" and "Communication".

The Chula Warship owned by Jack Harkness had Om-Com capabilities. Chula ambulances were also equipped with nanogenes which could give Om-Com capabilities to soldiers. (DW: The Empty Child/The Doctor Dances)

The Atraxi also had the ability to remotely broadcast messages through any speaker-grill as well as televisions, but it is unknown if this was a form of Om-Com. (DW: The Eleventh Hour)
