LTR Dispatch-Only
The Model 452 is a deluxe LTR-compatible repeater controller that combines the functions of LTR logic, dispatch controller, subscriber validation, airtime accumulation for billing, and system management in one unit. With an external modem, the Model 452 supports connection to a central PC to retrieve billing records, to monitor real time traffic, and to collect repeater loading statistics. The Model 452 has a built-in cross-busy that enables the repeater's radio to be shared with a conventional repeater controller.

Functions seamlessly with Model 459, allowing system-wide smart channel allocation, automatic program cloning, and one-shot data download.
