This board came in recently in an old modem:

Nice looking WE chips. Two are socketed and one is soldered on the board.

Hi,
very nice little card. The ceramic DIP with 2 chips looks like (even if the part number isn't the same) the WE chips used by AT&T in several vintage Merlin PABX digital-line (ISDN) and analog-line modules. If I correctly remember, these chips are dual subscriber line drivers. A nice find indeed.
