First time poster, and a clueless newbie. I hope you guys can help me. I'm very familiar with IP based systems, but I have a client that has an old analog system running off the Valcom 2003a. I see the Algo 8301 would work with what we have. The Valcom runs to a 66 block. The Algo has audio and relay inputs/outputs. Where I'm clueless is I've never worked with analog before. I know nothing about this stuff. The diagram is on page 7 of a PDF found here: www.valcom.com/pdf/v-2003av-200ahf.pdf

I just don't quite see where to I should punch this down to connect these so that paging would work as an all call. Does anybody know about these things that could point me in the right direction? I'm not seeing anything along the lines of audio in. Thanks.
