If 3 out ofany 4 polling cycles fail then both will place the link between usand the FR switch in a “link down” state. This will cause allDLCIs to be set to inactive, and no data placed on the wire (otherthan polling messages) until the service affecting condition iscleared. This service affecting condition can be the result of anumber of things:- Our STATUS ENQUIRY message never reaches the FRswitch, due to: our WAN driver, or our physical WANconnection to the Fr switch dropping the packet for somereason.- The STATUS RESPONSE message never reaches the FRprotocol code, due to: our WAN driver, or our physical WANconnection to the Fr switch, or the FR switch itself droppingthe packet for some reason.- The incorrect LMI type Si selected at our side or the Frswitch side. If they do not match, then polling errors willresult.
