Section 700 - Operation576-50-700 DBS 576 (USA) issued September 2001 A-5Time List TableTime List Table is used when the time of day, the day of week or the date affects the desired route. The TimeList Table allows up to 50 patterns to be entered. Each pattern may specify up to five Route List patterns toused based on the current time of day.Up to four Time List tables may be used. The referenced time list table is determined by the Special Day Tableor the Day of Week Table. This is useful when rates change for certain days (such as weekend rates versusweekday rates).Route List TableThe Route List Table is used when there are multiple route possibilities. Up to 5 possible route table patternsmay be considered in sequential priority when attempting to find an available trunk. Before a route is tried, thesystem compares the route ARS to the originator’s ARS level. If the route ARS exceeds the originator’s ARS,the call processing will stop and the caller will receive busy tone.When the call is first presented, the first priority route is tried. If there is no available trunk in the first route andqueuing point is not enabled the system continues to the next priority route, compares the ARS levels and ifacceptable checks for an available trunk. If no trunk is available, it will continue to the next priority trunk, andso forth until all routes have been attempted.If an available trunk is found and warning tone is enable, the system will first issue a warning tone to the callerto allow the caller the opportunity to hang up before using a more expensive trunk.If the queuing point is enabled, the system will wait for an available trunk (beginning with the first prioritytrunk) until the queuing point timer expires before moving to the next possible route.Route TableThe Route Table provides a simple trunk group selection and selects any digit dialing modification needed.This table is directly referenced when there is only one route to use. It is also indirectly reference from theRoute List Table.Digit Modify TableOnce a route is selected, the actual dialed digits can be changed based on the Digit Modify Table. Digits can bedeleted from the beginning of the number (such as removing an unneeded area code), digits can be added to thebeginning of the number (such as adding an area code or equal access number) and digits can be added to theend of a number.TRS Configuration and OperationThis section provides the following:• An overview of the TRS operation.• An example TRS configuration - This is a simple example intended to introduce TRS planning andimplementation. Example worksheets are included.• Worksheets for planning and implementing a TRS plan.
