Those would have been the R model 3174s (R for remote). I was thinking of the T/R feature card for the channel-attached L models (we had an 11L with 1 coax card and 3 T/R cards -- nearly caused heart failure in that poor 3174 trying to keep up with all that traffic). Doesn't matter for this purpose, though (you still needed the SNA ucode diskettes in the 3174 and VTAM to use them). If I remember, you genned such a beast as a 3705 with some weird model number in VM. I faintly remember there being an Ethernet RPQ as well, but I don't think too many people bought them -- they were short-lived at best. We had AEA cards for one or two 3174s, too. (The 7171 was a FAR superior device, IMHO. There is a persistent rumor that John Naman wrote a SLIP driver for a 7171 and/or Series/1 device, but I can't seem to find any evidence of it...)
