Avaya OneCloud™ Subscription allows you to dynamically use the subscribed Avaya UC and CC applications. After you install and configure the Avaya Usage Metering Collector, you can use the Usage Metering Collector to add or remove the subscribed UC and CC applications from the Avaya OneCloud™ Subscription system depending on your service bundle order.

A service bundle is a collection of services that are grouped. An example of a service is the Avaya Aura® Experience Portal IVR service. An example of a service bundle is Calling plus Voicemail.

Usage Metering Collector collects usage data on a daily basis from data source applications, such as Avaya Call Management System (CMS), that are part of your Avaya OneCloud™ Subscription system. Usage Metering Collector uploads the usage data to the Usage Metering Processor. The Usage Metering Processor calculates the service usage data and sends the data to the Avaya back-office systems for usage reporting and invoicing.

You must set the time zone for daily usage calculations. For more information, see Setting the time zone.

Avaya OneCloud™ Subscription system is a collection of Avaya UC and CC applications (Single or Geo-redundant data centers) connected to one or more WebLM servers for licensing.

Avaya OneCloud™ Subscription supports sharing of applications, such as Avaya Aura® Messaging or CMS, between two or more Avaya OneCloud™ Subscription systems.

For more information, see Application sharing between two or more Avaya OneCloud Subscription systems.

Avaya OneCloud™ Subscription uses:

• Usage Metering to manage the Avaya OneCloud™ Subscription system.

• SAL Gateway for remote maintenance support.

If you have configured a secondary data center for High Availability, you must also configure a secondary Usage Metering and a secondary SAL Gateway.

Depending on your requirement and service bundle order type, you can use different Avaya UC and CC applications in different Avaya OneCloud™ Subscription systems. For example, you can subscribe for two Avaya OneCloud™ Subscription systems for your organization, one for the call center and one for the back office. You can choose to use Call Recording in the Avaya OneCloud™ Subscription system for the call center, and remove it from the Avaya OneCloud™ Subscription system for the back office.

For more information, see Avaya OneCloud Subscription system deployment models.

Avaya OneCloud™ Subscription system is a collection of Avaya UC and CC premise-deployed applications that are integrated with Avaya IT applications to enable an OpEX business model.
