Purpose

Data Transmission Equipment Unit (BAPD) TALM.465651.018 is intended for data exchange realization via two tone frequency leased channels between two interfaced with (BAPD) data processing equipment sets on one hand and two remote data processing equipment sets interfaced with similar (BAPD) or "Akkord SS-PD" data transmission equipment (APD AI-010) on the other hand.

Main functions

"BAPD" contains two independent semi-sets. Each of them provides:

• data reception from data processing equipment;
• received from data processing equipment data conversion into "Akkord SS-PD" format
  units;
• converted data transmission into tone frequency (direct) channel;
• data reception from tone frequency (backward) channel;
• reconversion of the data received from communication channel;
• received from communication channel and converted data transmission into data
  processing equipment set;
• communication channel and self operation condition diagnostics and indication;
• received and transmitted data delivery to the IBM PC type computer.

Adaptation capability

Data transmission equipment unit can be adapted to operation conditions and Customer requirements in the following specifications:

• Error protection unit use, error protection unit realized procedures;
• Transmitted data units length;
• Data processing equipment quantity and connection points (to error protection device and to signal conversion device);
• Communication channel type;
• Modems use;
• Transmission method and data rate;
• Design.
