IP Office Paging use Extension PORT 1

[Jhon88]

Hi All Masters,

I Have a plan to integrate IP Office with load speaker using analog amplifier to get paging them use extension port. detail scenario like this

some online data say:

according above data, how PIN OUT interconnection from POTS port with analog AMPLIFIER PORT. there are any port in analog amplifier like Aux In, Line in port.

doesn't need some capacitor or resistor to make same impedance between IPO and Amplifier when it connected ?

Yes it is mandatory to have a capacitor and a line transformator beteren them.
Use a BOGEN interface

As intrigrant says you need a transformer for isolation and to loop the port - it is in the manuals

More likely you'll want to add a device to do VOX switching, either to allow background music when there's no paging (or allowing the usual paging mic to be used) or maybe just to avoid the background hiss that's inevitable with a PA when there's no input. There are many options and some amps already have this stuff built in.

should I need to set wiring like this .. with UPAM module

so we can not connect directly from station port to Line IN port in analog amplifier., right ?

you should always use a transformer not a resistor (for isolation) and that doesn't look like the last UPAM I saw (but that was quite a long time ago) so I can't really comment more.

EDIT - and the UPAM (Bogen TAM-B) was not useable for an extension port set as paging speaker to my memory.

Maybe you could clarify exactly what you are trying to do - for example you you need the port set as paging speaker? (to do mixed phone and PA paging)

40 years of experience, there is not a lot that can beat that.

But with respect, the IP Office manual says that the port must be connected at boot so that implies that the IP Office is reliant on detecting a DC loop condition, which won't be possible given your inclusion of a capacitor...

Excellent spot TTT - the Paging interface device we used in the past is no longer in the Viking product listing and the one they have looks different enough for me to be nervous of suggesting it without having used it myself (or a trusted colleague).
