tion. Transmitting and receiving dat

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.
