AMIS Analog Networking

2. Estimate the anticipated length of each message. Each AMIS and/or
message delivery message requires an additional 45 seconds of
overhead to transmit.
3. Multiply the values from Steps 1 and 2 as follows:
(# messages) (average message length + 45 seconds) =
X seconds of port use
4. Divide the total seconds of projected port usage by 3600. This number
represents the
additional
port usage required to support this feature
during the busy hour.
X seconds of port use / 3600 = # additional port usage
5. Add this number to the maximum average number of ports in use. Refer to
the following "Monitor Voice Port Use" section for the form and field
needed on your system to get these values.
6. Use the table in the appropriate administration manual (see next section)
to determine if the resulting grade of service (GOS) will be acceptable
(refer to the following "Monitor Voice Port Use"). If not, plan to install the
recommended number of additional voice ports
before
implementing the
AMIS Analog Networking or Message Delivery features.
Monitor Voice Port Use
Use the following procedure to determine if additional voice ports may be
needed on your system. You may use this procedure after activating the AMIS
Analog Networking and/or Message Delivery features to determine their impact
(if any) on system performance.
For an AUDIX System:
1. Display the
traffic:feature:day
form and record the number
in the max average number of ports in use field.
2. Using the
AUDIX Administration,
585-305-501, manual, calculate
the grade of service (GOS).
3. Using the
DEFINITY AUDIX System — Administration
, 585-300-507,
manual, calculate the grade of service (GOS).
For an Intuity System:
1. Display the Feature Daily Traffic form using the
list measurements
feature day
command and record the number you see in the
Maximum Average Ports in Use
field.
2. Calculate the grade of service (GOS). For procedures, search your
Intuity documentation for grade of service (GOS).
For any of the systems, a GOS of .05 is recommended (a lower GOS is
desirable). If the GOS is greater than .05, additional voice ports should be
installed. Contact your sales representative.
