SGA - 155

The SGA-155 card is AITIA's solution for handling STM-1 network connections and for supporting applications with large computation demand. The wide application variety of the card is due to its large capacity FPGA: with a simple firmware change the whole application domain of STM-1 based networks can be covered (from ATM networks to asynchronously mapped PCM links). Further interfaces can be fitted using the feature connectors on the card - this way up to 40 E1 links can be covered with a single card, hence significantly reducing costs. The on-board memory prevents the card from turning to the host PC's CPU in unnecessarily.
