means the maximum time for two CH sequences to rendezvous when all licensed channels are available and maximum conditional time to rendezvous (MCTTR) means maximum time for two CH sequences to rendezvous when all channels are not surely available for all CR nodes.

Mean time to repair (or recovery) TABLE 1-12 Reliability Examples MTBF for an enterprise disk drive 1,000,000 hours MTBF for a NAS server 1,000 hours MTTR

Looking at our sample eight-block system, assume that the MTTR
consists of the following elements: travel time, 8 hr; troubleshooting time, 2 hr; repair time, 8 hr; and start-up time, 8 hr.
This local synchronizing process of the material flow simulation allowed us to change some of the manufacturing cycles introducing stochastic distribution laws values for MTBF, MTTR
or failed parts adapted to each work point characteristics.
In the case of experiments or on base of observations collected from exploitation the MTTR
can be calculating with formula:
This gears the box for rackmount communications applications, where MTTR
(mean time to repair) and downtime are critical.
Gaining visibility into each of these layers and correlating fault and performance data reduces MTTR
and improves service availability.

Breakdown level (BL) 0% 2.
Advanced thermal management features include active, controlled heat dissipation of the power supply and the boards through hot-swappable, speed controlled radial fan units for rapid MTTR
, and a unique bottom-hinged honeycomb ventilation panel for air intake.
This includes reducing repeat dispatches and mean time to repair, or MTTR
," said Sean Yarborough, senior director of business development & strategy at Spirent.
