Description: This field selects ATM cell payload format. Aal1 - ATM Adaption Layer Type 1. Yurie - A proprietary specific ATM cell payload format for compressed data.

What is twoWireSourceChannelEncapsulationAal?

This read-only OID reports which AAL (ATM Adaptation Layer) format is encapsulating the voice data into ATM cells—either AAL1 (uncompressed structured data) or a proprietary Yurie format (for compressed data). Engineers check this to understand how the voice stream is being packetized for transport over ATM. For example, if AAL1 is active, voice samples are placed into regularly-spaced cells for constant-bitrate transmission, whereas Yurie format optimizes for variable-rate compressed voice.
