- The Telcordia SR-332 Standard also provides models for predicting the failure rates of units and devices during the first year of operation. The failure rate during this wear-in phase is expressed as a multiplying factor operating on the predicted steady-state failure rate.
- Ttr-332 valuable feature comes in especially handy when tr332 is necessary to transfer data from bellcord project or library to another. An extended range of complexity for devices, and the addition of new devices. Tt-332 can also be used directly by telecommunications service providers for product reliability evaluation.

MTBF-Calculation acc. to Standards →Mil-HDBK-217 TelcordiaSR-332 IEC-TR-62380 SiemensSN 29500 FIDES2009 217Plus GJB/Z 299C | Mil-HDBK-217was the first electronic reliability prediction standardand is still the most popular ofall current electronic reliability prediction standards. Its initialrevision dates back to the early 1980s, and its latest revision F,notice 2 was issued in 1995. Among all electronic reliability standards, Mil-HDBK-217 has still thebest componentcoverage, which makes it a versatile all-rounder. |
As of 2015, updates are not planned. Taking into account thatreliability prediction standards are based upon field failure datacollected over many years, we can conclude that Mil-HDBK-217F notice 2reflects the electronic status quo of the late 1980s.
It is obvious that using the Mil-HDBK-217F notice 2 in its originalmanner would yield results that don't have any reasonable relationshipwith today's electronics.
Despite the RoHS directive, today's commercial electronic componentsare beyond any doubt more reliable than military grade components havebeen in the 1990s.
This problem has been addressed by a consortium of military andaviation companies by developing the ANSI/VITA 51.1 in 2008.

ANSI/VITA 51.1can be perceived as anadd-on for the Mil-HDBK-217.![Handbook Handbook](https://www.itemsoftware.com/assets/screens/telcordia_sm_1.jpg)
Members of theANSI/VITA 51.1consortium were Boeing, Northrop Grumman, GE, Honeywell, just tomention a few, as well as former Relexsoftware company, whosereliability software suite Relex has been taken over by PTC and renamedinto WindchillQuality Solutions in 2010.
ANSI/VITA 51.1containsrecommendations for quality factor assessment for today's commercialelectronic components. By applying ANSI/VITA 51.1, Mil-HDBK-217 resultson component level would improve by a factor between 1 (switches,connectors, quartz, fuse) and 100 (birdseed like R and C), depending onthe component type. On PCB level, results would improve by a factor of3 to 5, which is still pessimistic.
Improvementfactor = 1 means noimprovement at all. For whatever reason, the consortion has recommendedthat for switches and connectors, quality factors shall beassessed in the original Mil-HDBK-217 manner, and for fuses andquartzes, there is no recommendation at all.
