BP250 - is ring generator on ELU-A working ?

[TheCurious]

Hi folks,

Is it possible to find out if ring generator on ELU-A is working or faulty ?
Would any tracing, warning logs or extension supervision from BMS show anything if ring generator is faulty ?

In my case BP50 behaves like this:
Extensions from ELU-A can call digital extensions.
Digital extensions can't call extensions from ELU-A, after dialing the digits, digital telephone shows message PARK

Maybe ring generator on ELU-A is faulty, and system knows that it is not possible to complete the call ?

Stick a meter on the end of the line and ring it !

Hi Ceejay,

Good point, but unfortunatelly it cannot be used in this case.
When I call extensions located on ELU-A:
- If I call from analog extension - call is rejected
- If I call from digital extension - call is immediately parked on line 1

So, there is no ringing period at all, voltage measurement is not possible.

Thanks for your opinion,
