ZMUX-1215 Digital Circuit Protection Switching Equipment
Keywords:
Product Overview
ZMUX-1215 is a protection‑switching device specifically designed for digital circuits, primarily used to provide primary–backup redundancy for E1 (2 Mbit/s) lines. The device features 15 primary E1 interfaces and 15 backup E1 interfaces, supporting protection for 15 user‑side E1 circuits. When the primary E1 line fails, the device automatically switches to the backup line, ensuring uninterrupted digital transmission services. It is suitable for a wide range of digital applications, including telecommunications, data transmission, and surveillance.
Product Features
Highly Integrated Hardware Design: Standard 19-inch 1U rack-mount design, offering flexible installation and ideal for high-density deployments.
Energy-saving and quiet operation: The device consumes less than 15 W of power, features a fanless, silent design, and supports continuous, stable operation 24/7.
Interface aggregation and reliability: The primary, backup, and user interfaces each utilize a single DB62 connector; each connector supports the接入 of 15 E1 digital circuits, ensuring simple wiring and efficient maintenance.
One-click quick switchover: In manual mode, a single button press can switch all 15 E1 lines to either the primary or backup side.
Flexible software control: Supports on-demand selection of single‑path, multi‑path, or full‑line switching via software, with precise and controllable operation.
Power outage direct connectivity guarantee: When the equipment loses power, it automatically switches to the primary line, ensuring uninterrupted communication.
Strong cascading scalability: Supports cascading up to 256 devices, with a total system capacity of up to 3,840 E1 channels, easily handling large-scale network deployments.
Multiple communication interfaces: Supports three communication protocols—Ethernet, RS-232, and RS-485—enabling flexible adaptation to diverse monitoring environments.
Dual-power redundant protection: Supports dual‑power redundant inputs, offering flexible power supply options, including dual 220V AC, dual 48V DC, or a hybrid AC/DC configuration, thereby enhancing system power reliability.
