Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telephone network voltage (TNV) circuits. LAN ports contain SELV circuits and WAN
ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. To see
translations of the warnings that appear in this publication, refer to the Regulatory
Compliance and Safety Information that accompanied this device.

Step 2 For T1 cabling, attach the network end of your CT1 cables to your external network.
Step 3 For E1 cabling, attach the network end of your CE1 cables to your network termination (NT1) device.
