The OLA tests are very good for testing devices at the byte level, i.e. what's in the packets.

But they are of limited use for testing transparent inline devices like repeaters.

To test a repeater, you mostly need to test *timing*. Short breaks, long breaks, responders that reply a bit too quickly, responders that take a bit too long to reply, responders that don't reply, truncated replies, line-driver enable glitches, discovery collisions, responses that have a 2ms pause in the middle, etc.

Also, you'll probably want to figure out why it's failing at 6 repeaters. With only 8us of delay you are well below the 88us that the standard allows, so it's not a delay problem. Are you introducing bit jitter to the signal?
