Program RESPONSIBLE J.N. Gamble GROUP CN/CS Tele. 3105

This message will appear if external circuits go down to DECnet areas with no backup routes. Connectivity is lost either due to PTT disruption on the leased line or problems with equipment at the remote end. If the alarm shows more than one DECnet circuit down there may be problems with equipment locally at CERN. Contact (working hours) NETOPS (4927) or D. Heagerty (4975) See also DECnet Operational Recipes.
