Let me clarify. A few of us have reached out to various people about both 3B2 and WE32k information. The main response them has been it's still in-use to varying degrees by customers. I assume through emulation to keep legacy systems running. And they cannot release any details.
The two people that would know the most about the status of that IP is William Caughlin at the AT&T Archives and Ed Eckert - Archivist at Nokia Bell Labs.

My understanding is all the WE IP was retained through the Alcatel-Lucent mergers and is now owned by Nokia. That would include all the 3Bx systems and WE32k.
