AT&T 555-230-520 manual Figure M-5. Example Vector with Improved Performance

Looping Examples

The example in Figure M-5adds a delay so that the lookahead interflow attempt occurs only every 10 seconds.

1.queue-to main split 1 pri l

2.announcement 3000

3.wait-time 20 seconds hearing music

4.route-to number 93035555555 cov n if unconditionally

5.wait-time 10 seconds hearing music

6.goto step 4 if unconditionally

Figure M-5. Example Vector with Improved Performance

The example in Figure M-6increases performance even more by increasing the delay between lookahead interflow attempts to 30 seconds.

1.queue-to main split 1 pri l

2.announcement 3000

3.wait-time 20 seconds hearing music

4.route-to number 93035555555 cov n if unconditionally

5.wait-time 30 seconds hearing music

6.goto step 4 if unconditionally

Figure M-6. Another Example Vector with Improved Performance

Table M-2compares the relative processing cost of the three examples by looking at the approximate number of vector steps executed while processing the call. Assumption is that the announcement is 5 seconds long.

Table M-2. Approximate Number of Vector Steps Executed for Lookahead Interflow Examples

	Example in	Example in	Example in
	Figure M-4	Figure M-5	Figure M-6
when a agent is available in	1	1	1
split 1
queueing time of 5 minutes	up to 1,000	85	30

When a call is queued for 5 minutes, the amount of vector steps drops dramatically when a delay is added (Figure M-5),and drops even more when the length of the delay is increased (Figure M-6).When an agent in split 1 is immediately available to answer the call, there is no difference in the amount of vector steps for the three examples.
