Understanding the port capacities for the DEFINITY AUDIX system
Release 4.0 will help customers decide which port packages are right
for their organizations’ needs.
Features that Affect Voice Ports
Some of the DEFINITY AUDIX system’s features can place varying
demands on the system’s resources. Among those features that have
unique requirements for voice ports are Outcalling, Automated
Attendant, and Broadcast Messaging. The DOSS configurator—Lucent
Technologies’ system for configuring products according to customers’
needs—calculates the requirements for these features individually. It is
particularly important for customers who specify their voice port
requirements to understand these demands so they can accurately
predict their systems’ performance.
Outcalling
For Outcalling, the DOSS configurator uses the following estimates to
calculate voice port requirements:
■ The total number of outcalls during the busiest hour of the day
■ The fraction of total outcalls that go to a pager
The DOSS configurator also assumes the following:
■ A successful outcall takes 15 seconds; an unsuccessful outcall
takes 60 seconds.
■ 50% of outcalls that do not go to a pager are successful.
■ The switch treats all outcalls that go to a pager as unsuccessful.
Automated Attendant
For Automated Attendant, the DOSS configurator uses the following
estimates to calculate voice port requirements:
■ The number of Automated Attendant calls during the busy hour
■ The holding time per call
Broadcast Messaging
For Broadcast Messaging, the DOSS configurator uses the following
estimates to calculate voice port requirements:
■ The total number of broadcast messages the customer
organization generates per day
■ The average length of a broadcast message in seconds
