Is this possible? I have a current ISDN trunk that has an external CSU/DSU attached. Private line between sites. 7 channels are being passed to the PBX. I am looking to increase this. If I add another member (next port on the board) it shows as insrv/idle when statused. This throws me as I have not changed the CSU map or even added the member on the far end.
I wanted to do a facility test call to verify the member is live (once I make all the appropriate changes). I get a reorder (I think this is what it is called) tone any time I try to place a facility test call on an ISDN trunk (tried other trunks on same system, and other systems). I have verified FTC's work on my CO lines, so I know my FAC is correct and I am typing the proper string.
