Annex 36A in IEEE 802.3z describes several jitter test patterns. These can be configured to be sent by
writing the jitter diagnostics register. See the register description for more information. In may be wise to
auto-negotiate and advertise a remote fault signaling of offline prior to beginning the test patterns.
