The HJ-A2001 integrated multiplexer is a point-to-point transmission device developed based on large-scale programmable logic devices, enabling the mixed multiplexing and transmission of 100M line-speed Ethernet data channels, telephone, standard E1, and asynchronous data RS485/422/232.

The equipment features comprehensive alarm and monitoring functions, high integration, low power consumption, stable performance, and ease of use.

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

Feature Highlights:

1. Designed with telecommunication-grade product specifications, 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 offer excellent overcurrent, overvoltage, and lightning protection. They pass the ITU-T K.20 tests for lightning impulse, electrical induction, and electrical contact, and can automatically recover after circuit impulse release.

4. Dual backup access with 1+1 optical ports

5. E1 port with 1+1 dual backup access

6. Ethernet Interface Functional Features Description:

10/100M Ethernet interface auto-negotiation, straight-through and crossover cables auto-negotiation

7. Strong testing features with comprehensive alerting and loopback testing capabilities:

The equipment features a comprehensive panel alarm indication function, including optical path status, E1 interface status, trunk pick-up/hang-up status, Ethernet link status, and remote alarm. With 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 states during equipment operation.
