Find out the following values from your ISP before you change them.

VPI: Virtual Path Identifier. The valid range is 0 to 255.

VCI: Virtual Channel Identifier. The valid range is 32 to 65535.

Service Category: Five classes of traffic are listed:

oUBR Without PCR (Unspecified Bit Rate without Peak Cell Rate)— UBR service is suitable for applications that can tolerate variable delays and some cell losses. Applications suitable for UBR service include text/data/image transfer, messaging, distribution, and retrieval and also for remote terminal applications such as telecommuting.

oUBR With PCR (Unspecified Bit Rate with Peak Cell Rate)

oCBR (Constant Bit Rate)— Used by applications that require a fixed data rate that is continuously available during the connection time. It is commonly used for uncompressed audio and video information such as videoconferencing, interactive audio (telephony), audio / video distribution (e.g. television, distance learning, and pay-per-view), and audio / video retrieval (e.g. video-on-demand and audio library).

oNon Realtime VBR (Non-Real-time Variable Bit Rate)— Can be used for data transfers that have critical response-time requirements such as airline reservations, banking transactions, and process monitoring.

oRealtime VBR (Real-time Variable Bit Rate)— Used by time-sensitive applications such as real-time video. Rt-VBR service allows the network more flexibility than CBR.

To enable the Quality of Service function, it must be enabled on the previous screen in order for the traffic classification rule that you specify (later in the Quality of Service Screen under Advanced Setup) to be activated. Once a PVC is setup with QoS, two more PVC queues will be used up for this function meaning 3 PVC queues will be used. Note there is a total of 8 PVC queues available for this unit.
