The following table lists the average number of subscribers Message Networking
supports for each connection type for very light, light, medium,
heavy, and very heavy usage levels.
Notes:
- The numbers provides are based on an average voice message of
60 seconds.
- The numbers assume that a message recipient is on a remote system
20% of the time.
- The numbers assume that 13% of all message traffic occurs during
the busy hour.
- The number are based on the assumption that the average message
goes to 1.4 recipients.
- If system traffic numbers are exceeded, system performance will
be degraded and it will take longer to deliver messages.
- Customers can adjust these subscriber numbers as necessary for
their own networks.

The following table defines the usage profiles used when calculating
the average subscribers for each connection type. The usage levels
are defined for each message component type.
| Component Type |
Average Component Size |
Average Number of Messages/Subscriber/Day
(in and out) |
| Voice |
(Seconds)
Short=30, Medium=60, Long=120 |
Very Light=0.2, Light=0.4, Medium=2.0, Heavy=4.0, Very Heavy=8
Use approximately 10% more if Enterprise Lists will be used
on a 5.4 Interchange in the network; use 25% more for AMIS.
