The HJ-A2001C Telephone Optical Terminal 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 and telephony.

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, highways, telecommunications, mobile, Unicom, and other communication networks.

Features:

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

2. The equipment features a three-level lightning protection system with overcurrent and overvoltage protection (extremely important due to outdoor user wiring), and passes ITU-T K.20 tests on lightning impulse, electrical induction, and electrical contact. After circuit impulse release, it can automatically recover.

3. Ethernet interface auto-negotiating, supports auto-negotiation mode, operates in full-duplex/half-duplex.

4. Features Ethernet Loopback Prevention (when a fiber optic line experiences a loopback, Ethernet data is not looped back, effectively preventing network paralysis that could be caused by Ethernet loopback).

5. The equipment power supply is DC 5V or AC 220V.

6. Strong anti-interference capability, stable performance, and comprehensive functions.

7. Comprehensive network management features, real-time detection of various device statuses (optional);

8. Desktop design
