ATM

This section of the WAN window allows the user to adjust ATM Quality of Service (QoS) or traffic parameters to suit specific traffic requirements. For applications or circumstances where packet loss or packet delay are a concern, ATM QoS can be adjusted to minimize problems. For most accounts, it will not be necessary to change these settings. Altering QoS settings can adversely affect performance of some commonly used Internet applications.

If you plan to change QoS or traffic parameters, contact your ISP or network services provider for information on what types of adjustment are available or possible for your account. Your ISP may not support the class of service you want to use.

Service Category: This field represents the QoS (Quality of Service) feature for the modem. The choices available from the pull down menu include UBR (Unspecified Bit Rate), CBR (Constant Bit Rate) and VBR (Variable Bit Rate). These values should already be set for you and should not be changed unless specified by your ISP.

•UBR – Unspecified Bit Rate, this is the default category used for general-purpose Internet traffic where normal levels of packet loss and delay are acceptable. For some applications or for multiple connection accounts, it may be desirable to specify the PCR.
