Hi everyone! We recently had an MST200 fail on us that was one end of a point-to-point link. My question here is twofold. First, it looks like the MST200 was discontinued. Is there a replacement model for this that could successfully form a bridge with an MST200 on the other end? Second, if we were to get a pair of 274s or 277s instead, could they replace these devices and have the same functionality?
