The board says "Silicon Software" by Ready Systems Corp.
CN1 mates with CN3 on the base board.

High function microprocessor based FAX adapter that can provide voice prompting, telephone tone detection, and optical mark recognition functions when used with a suitable application program. Features include real-time processing of tasks such as compression (Image to Group 3), decompression, and format conversions (Group 3 to Group 4) within the adapter, as opposed to doing these tasks with software in the PS/2* computer's main processor. Can communicate with Group 3 facsimile devices over the public switched telephone network for the purpose of routing FAX data. Supports the IBM* Facsimile Support/400 program offering for the PS/2* computers, although it can be used with suitably developed programs for other PS/2 computer applications.
