	normally.
NT1	Network Termination 1 LED
	If the NT1 LED is on, the router detects
	the ISDN link integrity signal at the U
	interface and the internal S/T interface,
	indicating that an ISDN connection has
	been established.
	If the NT1 LED blinks once per second,
	the ISDN connection at the U interface
	is up and the internal S/T interface is
	coming up. If this condition persists, th
	ISDN port is either not configured o
	configured incorrectly.
	If the NT1 LED blinks 8 times per sec-
	ond, the ISDN connection at the internal
	S/T interface is up and the U interface is
	coming up.
	If the NT1 LED is off, the router is not
	detecting the ISDN link integrity signal.
	Check the BRI cable connection.
