When the computer which is attached to the local LAN attempts to access a host on the access server, the Express L128/L128T will dial the number pro- vided in the Connection List profile. The Express L128/L128T will provide one of two B-channels based on traffic demand and POTS port usage Express XLT model only. If no packet traffic is transmitted or received for the speci- fied number of seconds, the Express L128/L128T will disconnect the link until a computer on the local LAN again attempts to access a host on the access serv- er
