Here are 2 products I found for ~$2,000
CoALM (9U) from Cosystems
16 x 38.4k ports, full modem control
9U form factor
SunOS 4.1.1 driver
                                                CoSystems Distributor:
                                                WorkStation Plus
                                                510 351 2661 Kari Payne
781 from Xylogics
16 x 38.4k ports, full modem control
6U form factor + 6U to 9U adaptor

I haven't actually ordered either one, but they look good on paper.
Xylogics Annex terminal severs with similar features run around ~$5,000.
