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.
