Speaking as someone who has implemented many PLC-5's with many
different interfaces let me state my opinion here. In a Integrator 30
-> 19.2K RS-232 -> DH+ -> PLC-5 linkup, the botleneck, by an order of
magnitude is the Inetgrator 30.

I need to take a look at this. I am not familiar with it at ll.

As long as it had the required prefromance, his would be a hug win.

Beacuse DH+ is an AB propritory network, and the KF-2 is the only
supported way to get on the DH+ that can be used with current
generation Sun boxes. The alternative (PCMK card) is PC centric.
