You're a terminating, or 'eyeball', network if the preponderance of your customers are end-users, resi or biz. Small-biz networks that are single uplink count here, yes.
You're a transit network, if the preponderance of your customers are other networks, including larger business networks that are or might become multi-homed. In short, if the plurality of your customers have an ASN.
And for a chunk of time, we looked like a transit network for traffic that passed through us heading for Internet2, if you were looking at us from the Internet2 side, and damned few eyeballs unless you call a few dozen HPC clusters eyeballs. But if you were looking at us from our Cogent upstream, we looked like an eyeball network because we didn't provide those downstreams any transit in Cogent's direction, so all that was visible was our tens of thousands of eyeballs that were all looking at stuff that wasn't on Internet2. (And yes, things got "interesting" a few times in our routing swamp when we didn't keep straight which thing went where, and we leaked a route or two and looked like eyeballs to Internet2, or transit to Cogent...) So as I said, it depends on where you were looking at us from.
