4.5.4 Interface Cable

Interface cables (T1 cables) for the cards are 100-ohm straight-through shielded
cables, as shown in the following figure:
Figure 4-28 T1 cable
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.

4.5.5 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:
