Interface cable
Interface cables (T1 cables) for the FIC-T1/FIC-T1-F modules are 100-ohm straight-through shielded
cables, as shown in the following figure:
Figure 4-54 T1 cable
To extend a T1 cable, connect the cable to another one using a network interface connector with an
RJ-45 receptacle at each end.
