The LSI/120 board lets you connect D/121B voice boards to analog (loop start) telephone lines and provides signaling control, digital-to-analog conversion, and interference suppression of the telephony signal being processed.
Connects 12 analog telephone lines to PCM Expansion Bus (PEB) based computer telephony resources.
Incorporates industry-standard PCM Expansion Bus (PEB) architecture for sharing of facsimile, speech recognition and text-to-speech resources among call processing ports and for compatibility with existing PEB based applications.
Data and signaling information are transferred in real time between voice boards, network interfaces and other resources.
