Troubleshooting

Frequently Asked Questions about the WAN LNK LED

This list describes all known conditions indicated by the WAN LNK LED:

•

If the WAN LNK LED blinks continuously and never stays solid on, the
Cisco 600 series CPE never trains to a system such as the Cisco 6xxx series:

–

ADSL/SDSL line is not connected to the Cisco 600 series CPE.

–

Subscriber is locked on the Cisco 6xxx series.

–

Subscriber's LIM port is locked on the Cisco 6xxx series

–

Subscriber's LIM port is not associated to an ATU-C pool

–

ADSL/SDSL circuit is physically too long.

–

There is excessive noise on the ADSL/SDSL circuit.

•

If the CPE trains up and the WAN LNK LED turns off after approximately
105 seconds when the CPE is in routing mode, this means that the CPE PPP
requests are not getting answered by the equipment on the service provider's
network, such as a Cisco 7200 series or Cisco 6400. It takes 105 seconds for

Table 6-1

WAN Link LED Blink Patterns

Blink Pattern/Rate

Description

Steady ON

A link is established to the WAN port. All
parameters for physical and logical
connections are correctly set. The CPE
successfully transmits and receives data.

Continuous rapid blinking, about
3 blinks per second

The CPE is trying to establish a connection.
The pattern continues until a connection is
established.

Intermittent blinking.

For the Cisco 675: 6 rapid blinks
followed by a 2-second pause
before repeating.

For the Cisco 676 or 677: 5 rapid
blinks followed by a 2-second
pause before repeating.

The CPE is trying to establish a physical
connection. At this time, the training
session is not yet completed; there are no
logical connections and negotiated line
conditions with other equipment (such as
DSLAMs) are not yet established.

OFF

Check all connections. Ensure the WAN0
interface is not disabled.
