In singlesite and multisite BSR, with the adjust-by portion of the consider command, you can implement your preferences into the vectors.
You can assign a value of 0 to 100 in user adjustments. The server supplies the units of the value depending on the conditions whenever the consider step executes. For example, in the command consider split 1 pri h adjust-by 20, the server interprets adjust-by 20 to mean add 20 percent to the EWT, but add 20 seconds at the minimum.
Note:
If you define the user adjustment as a number of seconds, BSR is not efficient when EWT was high. If you define the user adjustment as a percentage, BSR is not efficient when EWT was low. Such efficiencies, while always important, become critical in multisite BSR applications where issues of trunk cost and capacity are involved.
For EWT of 1 to 100 seconds, an adjustment of 20 adds 20 seconds. Over 100 seconds, the same adjustment adds 20 percent to the EWT for the split or skill that is specified in the consider step. The following table shows the results of user adjustment to a range of EWT.
