The HJ-A2001 Integrated Multiplexer Device is a point-to-point transmission equipment developed based on large-scale programmable logic devices, achieving mixed multiplexing and transmission of 100M Ethernet data channels, telephony, standard E1, and asynchronous data RS485/422/232.

The equipment features comprehensive alarm and monitoring functions, high integration, low power consumption, stable performance, and easy operation.

Equipment is widely used in public security systems, banking systems, highways, telecommunications, mobile, Unicom, and other communication networks.

Features:

1. Featuring telecommunication-grade product design, the line side offers 1-2 PDH optical ports or E1 electrical ports.

2. All interface technical parameters comply with international or domestic relevant standards.

3. All interfaces feature excellent overcurrent, overvoltage, and lightning protection. Compliant with ITU-T K.20 standards for lightning impulse, electrical induction tests, and electrical contact tests, the circuit can automatically recover after the circuit impulse is released.

4. 1+1 dual backup optical port connection

5. E1 port with 1+1 dual backup access

6. Ethernet Interface Functional Features Description:

10/100M Auto-Negotiating Ethernet Interface, Parallel and Cross-Over Cable Auto-Negotiation

7. Robust testing capabilities with comprehensive alert and loopback testing functions:

The equipment features a comprehensive panel alarm indication function, including optical path status, E1 interface status, trunk pickup/hang-up status, Ethernet link status, and remote alarm. Based on the loopback test function, it reduces the fault scope, offering both local loopback and remote loopback capabilities.

1+1 modular power supply backup design: AC220V dual power supply method.

8. Comprehensive network management functions, real-time detection of various statuses during equipment operation.
