Yes, in these scenarios, we called the uplink the "back-channel" :-).
And it could be anything, including dial-up.

It was not uncommon to buy uplink via SCPC from one provider, and
downlink via DVB on an inclined orbit satellite from a totally different
provider. This was a very common model between 2000 - 2009, where your
uplink and downlink ISP's were vastly different.

And who says the Internet must be symmetric :-)?
