Multi-channel Digital Telegraph Equipment BAP CTA for Channel Formation

BAP CTA is a multichannel digital telegraphic equipment with channelisation functions. The CTA BAP consists of a base unit and a set of channel boards (modules). The base unit of the CTA BAP contains 12 boards.

It can be equipped with channel modules (up to 10 ITO modules and up to 2 MTT modules). BAP CTA is designed for digital processing of data received via: <ul> <li>- telegraphic lines of communication compacted in THF channels (0,3 -3,4 kHz);</li> </ul>-telegraphic communication lines compacted in E1 streams (G.703 standard); -telegraphic communication lines (C1-TG junction). Digitised data are transmitted between the CTA BAP modules (CAN bus is used) or transmitted to the PC.

Functioning parameters of all modules (speed, operating frequencies, signal levels, channel switching table) are stored in non-volatile memory. Interaction with the system of remote control and monitoring of the USDS is carried out by means of RS-232 or Ethernet interface.
