Message	What It Indicates
OOF at ISDN PRI (Active/Idle)	An Out of Frame (OOF) condition is detected on the
(ISDN PRI DBM only)	ISDN PRI interface. An OOF is declared when two
	out of four frame synchronization bits are in error.
	Active – Backup call was in progress.
	Idle – DBM was in Idle mode.
	Possible reasons include:
	Incompatible framing format between the ISDN
	network and the FrameSaver unit.
	ISDN network cabling problem.
	ISDN network problem.
OOF at Network 1	An Out of Frame (OOF) condition is detected on the
	network interface. Possible reasons include:
	Incompatible framing format between the network
	and the FrameSaver unit.
	TNetwork cabling problem.
	T1 facility problem.
PathIP_ Address Down,	A path on the network interface is unavailable.
DLCInnnn1	IP_Address is the IP address of the path endpoint,
	and nnnn is the DLCI which contains the path.
PLB Active, [Interface]	A Payload Loopback (PLB) is active on the specified
	interface.
Power Supply/Fan Alarm	The power supply output voltage has dropped below
(9000 Series Access Carrier only)	the specified tolerance level required for the system.
	Or the fan tray is not operating properly.
Primary Clock Failed	A failure of the primary clock source configured for
	the unit is detected and the secondary clock is
	providing the timing for the unit.
	This condition clears when the configured primary
	clock is restored.
Primary & Secondary Clocks	A failure of the primary and secondary clock sources
Failed	configured for the unit are detected and the internal
	clock is providing timing for the unit.
	The clock source will not automatically switch from
	internal until the primary clock source returns.
PVC Loopback Active, DLCI	A PVC Loopback is active on the specified DLCI on
nnnn, frame_relay_link 1,2	the frame relay link.

1nnnn indicates a DLCI number of 16 through 1007.

2frame relay link is one of the following:

–Net1-FR1. The frame relay link specified for the network interface, Network 1.

–Port-n. The frame relay link associated with the user data port.

–ISDN Link Name on a non-network ISDN DBM interface.

3Does not apply to a TS Management Link DLCI.
