When connecting the interface cable, pay attention to the mark on the interface to avoid wrong
insertion, which may damage the interface module or even the router host.

If outdoor cabling is involved, you need to install a lightning arrester at the input end of the
SIC-BU/SIC-BS interface cable to avoid lightning strike.
After the interface module is properly installed, follow these steps to connect the cable.
Step1 Verify the type of the ISDN line provided by your telecommunications service provider.
Step2 Connect the cable.

For SIC-1BS/SIC-2BS
If the line is an ISDN U-interface line, use an NT1 for conversion. Insert one end of the telephone cable
with ferrite core into the BRI S/T interface of SIC-1BS/SIC-2BS, and the other end to NT1.
If the line is an ISDN S/T interface line, insert one end of the telephone cable with ferrite core to the BRI
S/T interface of SIC-1BS/SIC-2BS, and connects the other end with the ISDN S/T interface line.
z
For SIC-1BU/SIC-2BU interface module
If the line is an ISDN U-interface line, insert one end of the telephone cable with ferrite core into the BRI
U interface of SIC-1BU/SIC-2BU, and connect the other end with the ISDN U-interface line.
If the line is an ISDN S/T interface line, contact your agent to change the interface module to
SIC-1BS/SIC-2BS.
Step3 Check the “ON” LED on the panel of the interface module. If the LED is on, the interface is powered on.
If the LED is off, contact your agent for help.
