DIP Switches
There is no DIP switch on the UTRP2, UTRP6, and UTRP9.
The UTRP3 or UTRP4 has three DIP switches numbered from SW1 to SW3. SW1 and SW2 are
used to set the grounding status of the eight E1s. SW3 is used to set matched impedance for the
eight E1s. Figure 3-20 shows the DIP switch on the UTRP3 or UTRP4.

Table 3-23, Table 3-24, and Table 3-25 describe how to set the DIP switches on the UTRP.
