For simplicities sake I am going to re-post what I have been discussing on the Saturn Netlink League forums. I am hoping someone can shed some light on the task at hand...
For years I had wished there was a way to play Saturn Netlink games in the same room, on two separate TV's and not be required to pay for a phone line, let alone 2 phone lines. I wanted to find a way to play the Netlink games in similar fashion to the Saturn's and Playstation's Link cable games. I could just imagine playing a Duke Match against a friend in the same room.
A helpful individual (Warp2063) suggested that a "telephone line simulator" should do the trick. Just plug the Netlink phone line cables from both Saturns into the device and start a Netlink match. The Saturn should dial out to the box and the other Saturn should pick up and the game should start.
Here was Warps reply. As I don't own one, I've never actually tested it, but it should work, as long as it provides both a dial tone for the dialing Saturn and a ring signal to the waiting Saturn. All it does is pretend to be a real phone line. The main difference is that it doesn't care what number you dial, as there's only one other place for your call to go.

There's the one I would buy, except I don't know if I want to dump $115 on it.
So I followed up and did a bit of research on the device. I found a review of the product on Amazon and with the specs listed on the page linked to above, It looks like it should work.
In North America, the standard ring cadence is "2-4", or two seconds of ringing followed by four seconds of silence. According to the review on Amazon this device does that amongst several other ring patterns. Here is everything they listed:
External DIP sets: Ring cadence (long-long, short-short-long, short long-short, 2-seconds on/4 seconds off), audio volume, and answer mode (immediate ringdown or 2-seconds of dial-tone followed by ringdown mode).
Also one of the features listed on the page above, was in fact... Connecting modems together. This really does sound like it will do the trick.
Has anyone here on DP tried doing this or have any suggestions or insight on the task at hand?
