This read-only value reports the ABR TRM (time between forward RM cells, an upper bound on RM-cell interval regardless of NRM) parameter for this SVC, ensuring the source sends an RM cell at least this often even during idle or low-traffic periods when NRM's cell-count trigger wouldn't otherwise fire. This guarantees the network still gets periodic congestion feedback opportunities even on a lightly loaded connection, preventing a stale rate estimate from persisting indefinitely. An engineer investigating why a low-traffic ABR SVC still responds reasonably to congestion despite sending few cells would find cktAbrTRM enforcing a maximum time gap between RM cells.
