10.OVERALL PERFORMANCE

10.1Mean Time Between Failures (MTBF)

The MTBF for the overall machine will exceed (3,000) hours of actual operation. The MTBF will be measurable at a confidence level of 95 percent under controlled laboratory conditions.

The MTBF will be based on 50 percent transmit and 50 percent receive activity.

10.2Standardization

The machine will meet all specifications established by the 1996 version of ITU-T recommendation, as follows:

Recommendation T.4 - Group 3

Recommendation T.30 - Procedures

10.3Image Transmission Time

The time required to send a “ITU-T No. 1 Test Chart” from the machine to another Group 3 facsimile machine or between FX-051 machines, will not exceed the values listed in Table 10- 1.
