		holdover interrupt to indicate an error in its clock source.
	• Holdover rcvd by Backup Card—The backup TCC+ card generated a
		holdover interrupt to indicate an error in the clock source being
		received by either the Active or Backup card.
	• Bad Clock reported by CLC(s)—A cable interface line card reported
		that the clock signal being received from the TCC+ card is faulty.
	• TRU Loss of Sync—The clock hardware on the TCC+ card reported a

		failure.
	To correct the problem:
	1.	If an external clock source is being used, check that the clock source
		is valid national clock source, such as a GPS receiver or BITS clock.
	2.	If the clock source is valid, remove and reinsert the faulty TCC+ card.
