For the pinouts of T1 cable, see Low-End and Mid-Range Series Routers Cable Manual.
Relevant cables are included in the standard shipment package of SIC-TPRI/SIC-1T1-F. Order them
together with SIC-TPRI/SIC-1T1-F. By default, they are not supplied.
Connecting the interface cable
z
Connect a cable to the port with the correct mark. Improper plugging is prone to impair the SIC/MIM
and even damage the router.

When using T1 cable outdoors, you are recommended to install a special lightning arrester on the
input end of the cable so as to avoid lightning more effectively.
If the SIC has been properly installed, follow these steps to connect the cable:
Step1 Connect one end of the T1 cable to the RJ-45 port of SIC-TPRI/SIC-1T1-F;
Step2 Connect the other end of the T1 cable to the relevant equipment;
Step3 Check the status of LINK LED on the SIC-TPRI/SIC-1T1-F panel: ON means the link is connected and
OFF means the link is not connected. In the latter case, check the line.
