Product Overview
ZMUX-4104M is an Ethernet-based multi-service access and transmission platform meticulously crafted by Guangzhou Yinxun Comm.Tech.Co..Ltd. It not only preserves the stability of traditional TDM services but also innovatively integrates IP Ethernet transmission capabilities, eliminating reliance on conventional E1 or fiber-optic dedicated lines. Instead, it can directly leverage existing IP networks to carry voice, data, and serial‑industry services. There’s no need to lease additional dedicated lines or undertake large‑scale upgrades to the current network; a single network cable suffices to enable cross‑regional service interconnection. Whether for enterprise intranets, operator IP metropolitan area networks, or wireless backhaul links, it can serve as a service‑carrying channel, significantly reducing networking costs and enhancing deployment flexibility. The device combines multi‑service access, IP‑based transmission, and high‑reliability assurance in one, specifically designed to efficiently, securely, and stably transmit critical business signals such as voice, data, network, and video, making it an ideal cornerstone for building modern communication systems.
Core Competencies
Outstanding design, robust and reliable
Standard rack, flexible deployment: A standard 19-inch, 4U‑high rack‑mount modular design that can be easily installed in a standard cabinet.
Highly integrated modular architecture: Composed of a system chassis, power supply board, control board, and I/O interface board, it features high density and a high degree of integration, with convenient maintenance.
Powerful scalability: Supports configuration of two power supply boards (1+1 redundancy), two control boards (1+1 redundancy), and twelve I/O interface boards, meeting current and future diverse service‑access requirements.
Multi-layered protection, no business optimization.
Dual‑controller redundancy: Core modules such as the control plane, cross‑connect, and network management unit are configured with 1+1 hot standby, ensuring millisecond‑level switchover of the control plane and zero service interruption.
Dual-power protection: The power supply board features a 1+1 redundant configuration, supports hot-swapping, and ensures continuous, stable system operation even in the event of a single‑power failure.
Multi-link protection: A multi-link protection mechanism that automatically detects and switches over to a backup link, significantly enhancing network resilience and service reliability.
No downtime required for maintenance: All line cards support hot-swapping, and module replacement does not disrupt service operations.
Smart management, experience first.
Intelligent Service Scheduling: Efficiently schedules and manages service traffic, optimizing network resource utilization.
QoS Priority Assurance: Flexibly configure transmission priorities and bandwidth for voice, data, video, and other services, ensuring low latency, low jitter, and stable, reliable delivery for critical applications.
Flexible, integrated transport for all services
Fine-grained port management: Allows flexible configuration of port parameters for each I/O interface board, accommodating complex networking requirements.
