ECU723 SigTEL Interface / Network Communication Card
The ECU723 is an optional system expansion device for SigTEL systems. It is specifically designed to allow an ECU-224 desk controller to be connected to an ECU-4, ECU-8 or ECU-16 SigTEL controller, helping simplify call handling on larger SigTEL applications.
The ECU723 mounts inside an ECU-4, ECU-8 or ECU-16 controller and, if required, can also be used to network that controller to another controller. It is not compatible with ECU-8NT controllers.
Note: For detailed wiring diagrams and full installation information, please refer to the main ECU-4/8/16 instructions.
