Figure 9 120-ohm 4E1 adapter cable
Figure 10 75-ohm 4E1 adapter cable
Both 75-ohm 4E1 adapter cable and 120-ohm 4E1 adapter cable are required for
4-port Channelized/4-port Fractional E1 FIC, but E1 cable is optional, so you need
to order the E1 cable when purchasing an 4-port Channelized FIC or 4-port
Fractional E1 FIC. Otherwise, it will not be provided.
