Applications

TC1905 is often used to extend emergency phone service to remote sites in campus networks that also require a dry contact connection. For example, it could be used to provide voice communications for a push button phone and also pass through a dry contact signal to close a remote relay or activate a camera. Other applications include using the inherent benefits of fiber optics to improve voice quality, eliminates electromagnetic interference (EMI) or maximize security.
