TDSO Frame Error Rate Measurement Description

The time period between the successful negotiation of a SO32 connection and the start of the FER Count

Period is based on the current long code state, and will range from 0 seconds to 10.24 seconds.

The mobile station also resets its frame counters upon receiving the first sync frame.

Figure 7. TDSO FER With Frame Count Set to 512 Frames

During the second sync frame interval, the mobile station keeps a running count of:

• Good Frames Received

• Bad Frames Received

• Blank Frames Received

• Bad Frames Instead of Blank Frames Received

• Total Bad Frames Received

Also during the second frame interval, the test set keeps a running count of:

• Good Frames Transmitted

• Blank Frames Transmitted

At the end of the second frame interval, the test set retrieves frame count data from the mobile station and

calculates percent FER based on the following formula:
