5012 SIC

8-Bit DIP Switch
The 1-Port Fractional E1 SIC is compatible with both 75-ohm impedance and
120-ohm impedance. The interface card matches different types of impedance
through an 8-bit DIP switch. By default, all eight positions of the DIP switch are on.
Table 21 lists the implications and configuration modes of the 1-Port Fractional E1
SIC internal 8 BIT DIP switch.
