THANKS DUDE. I HAPPENED TO FIND THE SOLUTION IN THE MEANTIME. THERE'S A 56K CIRCUIT THAT PROVIDES THE LINK FOR THE INTEGRATION. THE CIRCUIT LINKS THE OCTEL WITH CENTREX FROM THE CO. THE NORSTAR HAS ALL CENTREX LINES. THE LINK WAS DOWN AND JUST HAD TO GET A TECH TO THE CO TO POWER OFF THE MODEM THERE AT THE ORIGINATING END. LINK CAME RIGHT BACK AND WORKED.
