^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) * Allocations are limited to the primary FDDI ring.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) * The SBM provides recovery mechanisms to recover
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) * unused bandwidth also resolves T_Neg and

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) * machine inputs are sourced by the underlying
