These Dialogic boards have on-board CODECs and contain DSPs that provide a broad range of tone signaling capabilities.
The LSI/SC products are intelligent network interfaces containing a control processor for handling loop signaling and automatically answering incoming calls. These Dialogic boards are ISA AT form factor boards that install in a single 16-bit expansion slot.
