Hardware Management

If you change to a switch type that uses fewer ISDN B channels, you must remove unused ISDN and digital modem RAS ports after saving WAN setup changes. If you change to a switch type that uses more ISDN B channels, you must add ISDN and digital modem RAS ports after saving changes. This is because the number of ISDN B channels available as RAS ports differs in different locations (23 in North America and Japan; 30 in Europe and Australia). See Setting Up or Removing Channels as RAS Ports on page 90 for instructions.
