I want to implement at least two automatic ringdown circuits between line ports on my PARTNER ACS system and another non-PARTNER telephone system located in the same building. I would like to avoid paying the phone company to set this up as a service and I do have a wiring contractor who can make the connection. My questions are...

1. Is there any problem with automatic ringdown circuits on PARTNER ACS systems, i.e. will they work?

2. Do you know what type of signaling devices are needed to make a 2-wire loop behave like an ARD?

Thanks in advance!
