product description

ZMUX-3300 420T is a large-capacity telephone optical transmission equipment independently developed and produced by Guangzhou Yinxun Communication Technology Co., Ltd., based on optical fiber or E1 link, providing 1~128 telephone access and transmission services (expandable to 420 channels), with redundant backup function from working power, optical transmission board, transmission link, etc., is suitable for providing users with large-capacity telephone communication functions, ensuring safe and reliable transmission of telephone signals. The M30ETH board also has four RJ45 ports, which complete 1~4 Ethernet signal access and cross-multiplex to 1~4 E1 transmission. Each Ethernet is physically isolated and works independently, and bandwidth can be allocated arbitrarily.

The 128-channel telephone optical transceiver can also be combined with ZMUX-300 and ZMUX-30 to adapt to some special solutions, and it is also one of the economical and efficient solutions to reduce system input costs.

Features

Large capacity: With a 19-inch 6U chassis, it can provide 1~128 telephone access (expandable to 420 calls).

Safe and reliable: Optional power board redundancy, optical transmission board redundancy.

Flexible expansion: The system chassis adopts slot design. The slot does not limit various boards. It can replace or add corresponding voice interface boards according to current application requirements and future expansion requirements, thus achieving a flexible and complete solution.

Dual power input: Optional two-way DC-48V power input 1+1 automatic protection; central office equipment, remote equipment, each equipment can provide two completely independent working power boards, primary and backup protection.

Power monitoring: Support real-time monitoring of the working status of the central unit and remote unit's built-in power board, and also support the real-time monitoring function of the external Emerson switching power supply.

Transmission link: Flexible choice, optional fiber or E1 link uplink.

Transmission link: 1+1 protection of the transmission link, optional multi-path fiber or E1 link uplink, which can realize 1+1 protection switching of the transmission link, and the telephone communication in the handover process is not interrupted.

Centralized monitoring system: Optional network management function, which can monitor device configuration information, transmission link status, link protection status, and telephone interface status of the entire network.
