For both Calltech’s applications and realized projects, our engineers are obliged to know many communication protocols. What is more, they also have skills of analysis and implementation of protocols, reading programs and other applications responsible for exchange of data and protocol mediation.
We have wide knowledge on electrical and transmission protocols, and also on communication buses.
The most important of these protocols include:

• I2C / OneWire / TwoWire,
• RS 485 / 232 / 422,
• SCSI /FibreChannel,
• X.25 / ROSE / ISUP / INAP / SS7 / ...,
• MODBUS / ProfiBus / DLMS / IEC1434 / IEC1107 / IEC60850 / ...,
• SNP / OPC,
• TCP/IP, UDP/IP, GRE, SNMP, ...,
• GSM, GPRS,
• GPS (NMEA 0183, SeaTalk).
