If the Power LED is not illuminated, it is
unlikely the EAM2000-12 is receiving
power and none of the LEDs will be
illuminated.
E1 LK (Link)
solid green
E1 connection is established
An E1 link exists and the port may be
transmitting data but it is not receiving
any packets from the remote E1 modem.
pulsing

E1 connection is established and active
The port is receiving valid data or status
packets from the remote E1 modem.
no
illumination
Loss of Synchronization (LOS)
The incoming connection to the port
has been lost; no data is being
received.
If the outgoing connection from the port
has also been lost then the remote E1
modem will have LOS as well.
E1 RX
(Receiving)
flashing
amber
E1 activity
The port is either receiving data from the
remote E1 modem or statistical packets
from the IP DSLAM management.
solid amber heavy Rx traffic
The port is receiving large amounts of
data from the remote E1 modem.
no
illumination
no activity
A link may exist but the port is not
receiving any data from the remote E1
modem.
E1 TX
(Transmitting)
flashing
amber
E1 activity
The port is transmitting data to the
