Message waiting light on SLT's

[Hitechbuzz]

Hi Guys
I wonder if anyone knows how to bring on the message waiting light on a standard slt (analog phone). I understand that on a number of systems an 80v pulse is sent down the line briefly and this brings on the message waiting light. Can it be done on the MD110? Thanks for any ideas.

Many years ago, I worked with Hotel application.
There was this feature.

I don't remember now, how it was realised (board and PU), but it was definitely in.

Best regards

Thanks Avstral some one else may know the exact way or board required

this is only possible with an ELU30; it can do polarity reversal or voltage ramp. this can be controlled via the ICAT parameter of the extension

A couple of years ago I asked Damovo about supplying ELU30s so that I could provide message waiting notification lights on analogue phones. I was told that they are not available in the UK. Does anyone know if this is still the case?

ELU30 is specific for hotel application and those cards are not common available...
