The ADP1000 series products are reverse multiplexing devices developed and produced by our company using self-developed dedicated integrated circuits, which convert Ethernet packets into TDM streams. This allows Ethernet data to be transmitted over E1 networks, enabling user data access; it facilitates the transmission of Ethernet data across multiple E1 lines, overcoming the bandwidth limitations of a single E1, and makes it very convenient to utilize the abundant existing E1 resources in public networks to quickly establish a bandwidth IP data network.
The ADP1000 is widely used for broadband access in enterprises, educational institutions, and internet cafes, as well as for interconnecting WLANs. Its optimized delay design is particularly suitable for H.323 high-definition video conferencing systems.
The ADP1000 series products can all provide a centralized chassis structure with unified network management, making network configuration easier.
Features:
◆ Utilizes large-scale dedicated chips, resulting in simple circuitry, low power consumption, and high reliability.
◆ A complete product range is available, offering flexible configurations from 1 to 16 E1 channels, with E1 interface impedance supporting both 75Ω and 120Ω.
◆ E1 channels support built-in BERT (Bit Error Rate Test) functionality to test line errors.
◆ Supports automatic detection of E1 line loopback, issues alarm prompts, and automatically disables the Ethernet interface to avoid impacting downstream services.
◆ Provides 1 to 4 ports of 10/100Base-Tx, supporting 10/100M, full duplex, half duplex, and automatic negotiation mechanisms.
