The Routing Pattern Data worksheet provides an easy means to view the overall performance of the specified route pattern. For more information about Route Pattern data worksheet, see ARS/AAR Routing Pattern Data worksheet. The route pattern reports or worksheet do not identify a peak hour.
The Route Pattern Measurements report summarizes the data for the specified route pattern. Using this report, you can determine:
The distribution of traffic over the trunk groups in the pattern.
Whether the Facility Restriction Levels (FRL) are administered properly.
The number of trunks and trunk groups.
Route patterns are administered as a part of ARS, AAR, or UDP administration. After you analyze the data presented in this report, you can change the route pattern. For example, you can increase the number of trunk members or trunk groups. To make a change, go to the Routing Pattern screen.
To change the FRL for the routing pattern, go to the ARS/AAR/UDP Routing Pattern screen. A user attempting to originate calls over the routing pattern might be blocked because the number assigned to the user FRL is lower than the number assigned to the trunk group. A user cannot gain access to trunk groups with numbers that are higher than the user FRL. Ensure that the user FRL is same or lower than the trunk FRL.
If the report indicates a high number for the Calls Queued column or the Queue Overflow column, but the usage on trunks in the groups is low, identify the group of users who are attempting to originate calls but are blocked. Increase the FRL number for the identified group or groups of users by accessing the Class of Restriction screen.
If the report indicates a high Queue Overflow rate and a high usage rate for all trunk groups in the pattern, then this probably indicates there are not enough trunks. Generally, the simplest solution is to increase the number of first choice trunks. Another consideration is to add more trunk groups to the pattern. Perhaps the most drastic change is to reorganize the ARS/AAR/UDP routing patterns.
You must keep the number in the Calls Blocked column to the minimum.
Additional and related information is available on the Performance Summary report. For example, the Performance Summary report lists the five trunk groups with the highest percent of blocking during their peak hour. Furthermore, the report lists the trunk group members out of service. Also listed are the trunk members, by trunk group, that were not used during the reporting period.
The Trunk Groups and Wideband Trunk Groups reports provide measurement data that relates to the Routing Pattern Measurements report. For example, the total number of calls that overflow from the first choice trunk group is listed in the Grp Ovfl field. Depending on how the trunk group is administered, these overflow calls are rerouted to the other (second, third, and so on) trunk groups.
