With the AMO LSCHD, up to 8 schedules - designated with the letters A, B, C, .. G, H - can be defined in a table per internal traffic restriction group. These typically cover the week in schedules which correspond with call charging rates. Every internal traffic restriction group (ITR) has its own LCR schedule table. An entry is made for every day/hour combination, with minute and schedule. Every hour of every day is always assigned to a schedule. The minute determines the time within the hour at which the specified schedule is switched. If the current schedule for the expiring hour is unchanged, no switching occurs and the minute specification has no significance. The schedules configured in this way can be included during routing in AMO LDAT (parameter LSCHED), in order to determine a route (time based LCR).
