I shall make the Intel ethernet adapter 82566DM mounted on the mainboard (FOXCONN LS-36) of a DELL desktop PC (Type DCSM) transmit test patterns for Ethernet (100BASE-TX) Conformance Tests.
In detail I shall make it permanently transmit
1th a scrambled IDLE stream (4B/5B=11111) as a basic signal for Mask Test
(ANSI X3.263-1995 (R2000) Annex J)
2nd a scrambled HALT line state for Jitter Test
(IEEE 803.2-2000, 25.4.5 & ANSI X3.263-1995 (R2000) 9.1.9)
3rd a 01010101 NRZ bit sequence for Duty Cycle Distortion
(ANSI X3.263-1995 (R2000) 9.1.8)
Who can help me or/and tell me how to manage that?
