Patterns The best way to troubleshoot a modem disconnection problem is to look for patterns. Even if a pattern doesn't suggest a solution immediately, it might provide ideas for help desk agents or second-level support agents to work with. It's a good idea to record patterns. Following are some examples of patterns. The 1 Big Red modem pools all have an inactivity timeout of 40 minutes.
Network traffic is generated by actions like checking e-mail or opening a new web site.
This is because reading and composing e-mail in Outlook Express, Netscape Messenger, or Eudora does not generate network traffic. All 1 Big Red modem pools also have an absolute timeout of five hours. That means that if a user has been connected for five hours, whether they are using the connection or not it will be terminated. If a person picks up a phone connected to the line your modem is using, it will most likely cause the modem to disconnect. Another possible cause of frequent disconnects is modem incompatibilities.
