harry2314,
For item "a", do you mean AP00-A instead of "AA00A"? I'm guessing you do. This is the card that allows MCI (Message Center Interface) integration to your VM. The other cards you mention are the Main Processor (CP00B) and a BUS card (BS00B). The AP00 has a bank of 4 connectors (the white connector on the front of the card) that the RVS cable will connect to. One of them is programmed for MCI. You need to find out which one of those ports off of the AP00 card is programmed for MCI.
To do this check the following Commands within the PBX:
D001>80>? (very bottom port of connector - Port-0)
D001>100>? (one up from the bottom of connector - Port-1)
D001>120>? (two up from the bottom of connector - Port-2)
D001>140>? (very top port of connector - Port-3)
The ports on the AP00 card a designated 0, 1, 2, 3 counting from the BOTTOM up, not TOP down.
Which ever one equals "24" in the above command, that is the one for MCI and that is the port number the RVS cable is to be pluged into.
DEFAULT, COM2, not COM1 is used on the VM unit for the RVS cable. If the Modem for the VM is assigned to COM2 then yes, COM1 would need to be used.
