Data Interfaces

• Development of component parts to support X, V and I interfaces (X.21, X.25, X.51,     V.24, V.35, V.36, I.430) for application in telecommunication systems
• RS232 traffic logger
• RS232 interfaces for system management connections in different projects, e.g. partyline modem, QD2-F-Port (SISA)
• RS232 modem support for remote maintenance
• RS485 interfaces for different applications, e. g. backplane communication, partyline modem, system management connection, QD2 (SISA)
• USB development board, application as terminal equipment and server interface
• Bridge implementation for Fast Ethernet (10BASE-T, 100BASE-TX) networks
• Experiences with Ethernet
  - in design, measurement, conformance statements
  - board design
  - IEEE 802.3, 10BASE-T, 100BASE-TX/FX, 1000BASE-ZX/LX/SX
  - IEEE 802.3ae, 10GBASE-LR/ER
  - Experiences with ICs from Infineon, Intel, Marvell, Realtek and Vitesse

• SPI-Tracer (ISA PC-card for logging of external data up to bitrates of 1 Mbps)
• SNMP agent for monitoring of several RS232/optical connectable devices with appropriate management interfaces
• Design of optical interfaces for
  Ethernet, Fast Ethernet, Gigabit Ethernet, FDDI und Fiber Channel
• Back plane busses H.110 and CellBus
• Development of an hand-held EIB bus monitor, as an auxiliary equipment for electric installers. In addition to the monitor function, the equipment offers the possibility to influence and simulate actuators.
