2.5.1.2.2 If specified in section 2.4.1 or 2.4.2, determine the offered telco traffic due to voice

prompts

The average voice prompt takes about 7 seconds to be heard. If during your busiest hour, 25% of your

subscriber base receives a single message, then the number of seconds that a trunk will be in use for

voice prompts is:

trunk in use time (seconds) = # subscribers (from section 2.1.1) x 7 seconds x 25%

2.5.1.2.3 If voice messaging was specified in section 2.3.1, determine the offered telco traffic due

to voice messaging

The average voice message takes 15 seconds to be recorded and 15 seconds to be retrieved. If during

your busiest hour, 25% of your subscribers with voice messaging service receive a single message, then

the number of seconds that a trunk will be in use for voice mail is:

trunk in use time (seconds) = # subscribers (from section 2.3.2) x 30 seconds x 25%

2.5.1.2.4 Total offered traffic

The total offered traffic per hour is the total of the previous three sections.

trunk in use time (seconds) = time for paging (from section 2.5.1.2.1)

+ time for voice prompts (from section 2.5.1.2.2)

+ time for voice messaging (from section 2.5.1.2.3)

The total offered traffic converted to # hours is:

trunk in use time (hours) = trunk in use time (seconds) / 3600
