ISDN between PDC and BDC

My PDC and one of my BDC are connected via ISDN. I noticed there is some network traffic between my PDC and BDC so that the ISDN line is always on. How to reduce the traffic to the strict minimum. I want no more than one connection by hour (or two hours) to reduced the cost of my ISDN line. Thanks.
