Hi. I used to have a working 1a2 telephone system. I have a bell "shoebox" ksu with power supply, and 4 line cards. I also have a melco mc-9 Combination intercom. I will post pictures of the intercom, but assuming i hook the system back up with 4 2564 telephones, how would i hook up the mc-9 ?? Thanks.
