Nomad User’s Manual Chapter 10 – Call Performance Configuration Options

10 Call Performance Configuration Options

Nomad provides various configuration options for call performance testing. These options include:

 Mobile Originated Testing

 Mobile Terminated Testing

 Mobile-to-Mobile Testing

This section contains detailed instructions for each call performance configuration option.

10.1 Mobile Originated Testing

In a Mobile Originated test, the mobile test device makes calls to the Call Server for call control

testing. To perform Mobile Originated call performance testing:

 Set the volume of the test handset to the maximum volume for optimal Audio Verification

results.

 Determine which channel the test will be conducted on. All call performance testing

operates via Bluetooth connection.

 On the Nomad Test Setup screen, configure that channel as a Mobile Originated task with

the following settings in the Call Campaign dialog:

o Dial/Answer Method: This field will only be visible to customers who have

purchased the ability to control devices via a tethered connection. This drop-down

allows those customers to choose between controlling via the Bluetooth connection,

or the tethered connection.

o Phone Number Settings: Enter the Number to call as provided by Spirent and the

Number calling from.

o Call Initiation Mode:

 Synchronous Testing – Calls start simultaneously on all devices regardless

of call outcomes. For example, if one device drops a call, it will remain idle

until the next time all mobiles are scheduled to start a new call.

 Asynchronous Testing – Each device follows its own call sequence without

regard to other device progress. In this mode, if one device drops a call, it

will wait for the specified time and then start a new call, even as the other

devices continue their first call.

o Access Timeout – A call attempt that has not connected within this amount of time

will be classified as an Access Timeout event.

o Duration – The length of each call in the test sequence.

 In a Synchronous campaign, this refers to the total attempt duration

including access time and connected time.

 In an Asynchronous campaign, this refers to the connected time only.

o Wait Time – The amount of idle time between the end of one call in the sequence

and the start of the next call.

o Attempts – The number of calls to attempt in this task sequence.
