You could place an AND gate between the last inverter/buffer and OR gate input with the other AND input being the line select taken from a logic point in the Unilink C30 box (assuming that I've got it right when I assume that the Unilink protocol itself has the on/off signalling in a serial packet of some sort and not in a dedicated on/off signal).

Otherwise, the LED output is turned off. This is fortunate, since switching would be a lot harder, actually nearly impossible without some active circuitry. BTW, this isn't the normal mode-of-operation for most Toslink devices. For example, a normal DVD player for home use doesn't turn off the LED output and there is always carrier signal even if there isn't modulation.
