25GbE LAN (25.781GHz), 10GbE LAN (10.3GHz) and
OTU-1e/OTU-2e (11.049/11.095GHz) Ethernet FEC
Interfaces support Seed A/B test patterns
Allows the user to enable or disable the Auto Negotiation
function.
Enabled - Enabling auto negotiation allows the system to
look at the incoming signal and automatically determine the
link speed and duplex mode of the port's remote device and
adjust accordingly.
Disabled - Disabling auto negotiation allows the test set to
simulate older Ethernet equipment that does not support auto
negotiation logic.
The Negotiate setting is only available for 1G and 2.5G
Optical Ethernet rates and 10M and 100M Electrical rates.
Electrical Ethernet rates require an Electrical RJ-45 SFP
module.
