This OID stores a true/false value that indicates whether all virtual circuits on this Frame Relay channel are sensitive to transmission delay. When set to true(1), the device routes all VCs based on delay as the primary criterion; when false(0), each individual VC uses its own delay sensitivity setting. A network engineer configures this to prioritize time-critical traffic like VoIP that cannot tolerate jitter and latency; set it true if the channel is dedicated to real-time applications.
