Examples include ***residential*** or ***business***. > [!NOTE] > Note > > A residential class of service may have different ALE values than a business class of service. ALE is a term used to indicate the number of equivalent access lines that one high-capacity date line such as T1 or ISDN represents. Access Line equivalents provide a more accurate means of comparing connection capacity, and are used for measuring revenue. The values in this table are used to populate the ***Class of Service*** drop-down list for Products, Packages, Pricing Plans, AdvancePay Products (wireless only), and Services in Product Catalog. To set up and maintain the Classes of Service table: - Under **Data Management** double-click **Classes of Service**.
