Actually it says idle mode is only used for SVCs, which I'm sure is what you meant to say and that's what's confusing you. I'm no X.25 expert, but idle mode probably occurs when there's no data and the devices are just sitting there sending Receiver Ready packets to each other. Closing the connection doesn't happen automatically. It requires one side to send a Clear Request message. The provider can also clear a call. Howard would know more. Have you read his X.25 paper at CertificationZone? It's great.
