The RTL8019AS is a Realtek Full-Duplex Ethernet Controller with Plug and Play Function. The RTL8019AS is a highly integrated Ethernet Controller which offers a simple solution to implement a Plug and Play NE2000 compatible adapter with full-duplex and power down features.

With the three level power down control features, the RTL8019AS is made to be an ideal choice of the network device for a GREEN PC system. The full-duplex function enables simultaneously transmission and reception on the twisted-pair link to a full-duplex Ethernet switching hub. This feature not only increases the channel bandwidth from 10 to 20 Mbps but also avoids the performance degrading problem due to the channel contention characteristics of the Ethernet CSMA/CD protocol. The Microsoft's Plug and Play function can relieve the users from pains of taking care the adapter's resource configurations such as IRQ, I/O, and memory address, etc.However, for special applications not to be used as a Plug and Play compatible device, the RTL8019AS also supports the jumper and proprietary jumper less options.

The Davicom DM562AP integrated modem is a two-chipset design that provides a complete solution for state of-the-art, voice-band Plain Old Telephone Switching (POTS) communication. The modem provides for Data (up to 56,000bps), Fax (up to ban0bps), Voice and Full Duplex Speaker-phone functions to comply with various international standards.

The design of the DM562AP is optimized for desktop personal computer applications, embedded microprocessor applications and Multi-Function Peripheral (MFP) FAX application. It provides a low cost, highly reliable, maximum integration, with the minimum amount of support required. The DM562AP modem can operate over a dial-up network (PSTN) or 2 wire leased lines. The modem integrates auto dial and answer capabilities, asynchronous data transmissions, serial and parallel interfaces, various tone detection schemes and data test modes.
