Chapter 4 Flexible Interface Cards (Router 6000)

To extend a T1 cable, you may connect the cable to another one using a network interface connector with an RJ-45 receptacle at each end.

Note:

Both T1 cable and network interface connector are optional accessories and are provided only when ordered.

4.8.5 Connecting the Interface Cable

Caution:

Before you connect a port, read its label carefully; a wrong connection can cause damages to the interface card and even the device.

If outdoor cabling is involved, consider to install a special lightning arrester at the input end of the T1 interface cable for better lightning protection.

Step 1: Insert one end of the T1 cable into the to-be-connected RJ-45 connector on the card.

Step 2: Connect the other end of the cable to another device directly if the cable is long enough. If not, extend the cable before you do that, as shown in the following figure:
