Test Status Message	Meaning
Network-init. DSU LB	A DSU Loopback initiated by the network is currently active.
Active	H If the network service is 56 kbps, the network loopback is
	non-latching. A non-latching loopback ends when the
	network activation codes stop.
	H If the network service is 64 kbps CC, the network loopback
	is latching. This condition can only occur when the Network
	Interface option Network-initiated DSU Loopback (64K CC)
	is enabled. Refer to Network Interface Options, Table A-2.
No Test Active	Status message, indicating no local, remote, or network test in
	progress.
Sending 511 on	A 511 test pattern is being sent over the network interface.
Network
Sending 511 on Port	A 511 test pattern is being sent over the DTE port.
V.54-initiated DSU LB	A DSU loopback is active that was initiated by the detection of
Active	a V.54 sequence originated by the remote unit. This condition
	can only occur when V.54 Initiated DSU Loopback is enabled.
	Refer to Network Interface Options, Table A-2.

Loopbacks

Loopbacks can be started from a variety of points in the network. Refer to

Table 7-2 for further information.

Loopback Type	Initiated By		Notes
Bilateral Loopback	H	ATI	When enabled, running a DSU loopback
	H	NMS	also automatically starts a local
			loopback. Refer to Data Port Options,
		Remote unit sending
	H		Table A-3, to enable.
		V.54 sequence
CSU Loopback	H	ATI (Network tests)	When initiated by the network, CSU
	H	NMS	Loopback cannot be disabled by the
			user. When IMC is enabled, the
		DDS Network, by
	H		aggregate data is looped back to the
		loop current reversal	network.
DSU Loopback	H	ATI	When IMC is enabled, only user data is
(Digital)	H	NMS	looped back to the network. Refer to
			Data Port Options, Table A-3.
Local Loopback	H	ATI	Control via CT141 can be disabled.
	H	DTE via CT141	Refer to Data Port Options, Table A-3.
