4.3. Bottom Dip-switch
There are 3 dip-switches on the bottom of equipment, SW1 (8-bit), SW2 (4-bit), and SW3 (8-bit). Please
use small flat-blade screw-driver to set the dip-switches.
Note: Please reboot the equipment after setting the dip-switches in order to make changes effective.

bits: V.35 interface bandwidth setup
V.35 bit rate is N*64kbps (N=1~31) when working at framed E1 mode; V.35 bit rate is 2048kbps when
working at unframed E1 mode. These 5 bits of the dip-switch are actually representing the binary code of
the N value. When N is configured to 0, RC801/803/805-30B-FV35 is working at unframed E1 mode.
