DDM-2000 OC-3 System Reliability Predictions
1
0
Example:
The unavailability of one 2-way DS3 channel within one DDM-2000 OC-3 system configured
to multiplex DS3 to OC-3, located in an uncontrolled environment, is 0.0662 minutes per year
(that is, fraction of time per year when the DS3 channel is unavailable). The mean time
between outage of the DS3 channel is 3608 years (that is, average length of time until a DS3
outage occurs).
Notes
:
1. Hardware failure rates are calculated per the RPP method, TR-NWT-000332, Issue 6,
"Reliability Prediction Procedure."
2. The environmental factor for the CO = 1.0 and for the RT = 1.5, per TR-NWT-000332,
Issue 4, "Reliability Prediction Procedure."
