Wild guess: analog phone; most likely some long distance lines related.

Well they don't look like test equipment, those would be have a GM or PM prefix for the model number. EL prefix is more likely something from the audio/video/communications part of Philips.

The front has a connector for use with a tape recorder, the rest I'm not sure.

Might be better to ask the same question on some vintage radio/technology etc. forums.

My best guess: some kind of induction loop amplifier. I can't find anything about this model but "EL" points at audio equipment.
