DIGITAL	The Digital Loopback Test is used to loop back DS0 data coming from the
LOOPBACK TEST	network for each channel. Received data is latched In on the appropriate re-
	ceive time slot on the receive bus. This data is then placed on the transmit
	bus in the unit’s transmit time slot.
NETWORK ON-	The Network On-Hook/Off-Hook Test is used to test signalling sent to the
HOOK/OFF-	network by the unit. When On-Hook Test is selected, On-Hook signalling is
HOOK TEST	sent to the network. When Off-Hook Test is selected, Off-Hook signalling is
	sent to the network. The customer loop is forced On-Hook while this test is
	active.
1004 HZ -	The 1004 Hz - 0dbm0 Tone Generation Test is used to send DRS signal on the
0DBM0 TONE	receive path to the loop. The loop receive level that should be received is de-

CUSTOMER RING	The Customer Ring Test will activate the unit’s ring relay in a 2-on/4-off ring
TEST	cadence, providing ringing to the customer loop.
TEST STATUS	Tells whether a test is in progress.
