By default, all DIP switches are ON, and the E1 interface impedance is 70 ohms, as shown in the
following figure:
Figure 172 Default DIP switch settings
H3C recommends that you use the DIP switch as follows: When the interface is connected to a
70-ohm cable, turn on switches BIT1 through 8; when the interface is connected to a 120-ohm cable,
turn off switches BIT1 through 8. Description for DIP switch settings is shown in the following table:
