Error Code	Explanation		Action
11	Lobe Media, Function Failure: The testing of the		1, 3, and
	lobe between the PC Card and the access unit has		5
	been unsuccessful because the lobe has a bit-error
	rate that is too high, or the PC Card cannot receive
	successfully.
24	Physical Insertion, Frequency Error: The PC Card has		2
	detected that the ring is operating at a speed other
	than the speed at which it was inserting.
26	Physical Insertion, Ring Failure: The PC Card, acting		1 and 2a
	as an active monitor, was unable to complete the
	ring purge function successfully. This indicates that
	an error condition has occurred since the successful
	completion of monitor contention (claim token),
	when this PC Card became the active monitor.
27	Physical Insertion, Ring Beaconing: The PC Card has		1, 2, and
	detected one of the following conditions:		2b
	■	The PC Card tried to insert on a ring that was
		operating at a different data rate.
	■	A monitor contention (claim token) failure
		occurred.
	■	The PC Card received a beacon MAC frame from
		thering.
2A	Physical Insertion, Remove Received: The PC Card has		2a and 4
	received a remove ring station MAC frame,
	indicating that a network management function has
	directed this PC Card to get off the ring.
2D	Physical Insertion, No Monitor Detected: RPL station		1 and 2a
	is the first station attempting to insert onto the ring.
2E	Physical Insertion, Monitor Contention Failed for		2
	RPL: Physical insertion failure of RPL station.
32	Address Verification, Signal Loss: The PC Card has		1 and 2a
	detected a 250-ms signal loss (receiver cannot
	recognize signal), indicating that an error condition
	has occurred since the PC Card successfully
	completed the ring signal recognition phase of the
	open operation.
35	Address Verification, Time Out: The insertion timer		1 and 2a
	expired before this function was completed,

indicating that the ring may be congested, experiencing a high bit error rate, or losing an abnormally high number of tokens or frames, thus preventing successful Address Verification MAC frame transmissions.
