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 defined are defined:

—UBR Without PCR (Unspecified Bit Rate without Peak Cell Rate)

—UBR With PCR (Unspecified Bit Rate with Peak Cell Rate) – UBR service is suitable for applications that can tolerate variable delays and some cell loss, such as data transfer, messaging, distribution, and retrieval, and remote terminal applications such as telecommuting.

—CBR (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), and audio and video distribution and retrieval.

—Non-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.

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