Cardassian Communications Service

The Cardassian Communications Service (also known as the Cardassian Information Service) was an agency that controlled and operated major communication systems in the Cardassian Union.

Natima Lang worked for the service while she was living on Terok Nor in 2363. At the time, Lang was romantically involved with Quark, who used Lang's computer access code to steal funds from the service.
