Jumper plug settings for normal power on the TX and RX leads
• Reverse power on the TX and RX leads. This option is used
only in Japan and provides power (-48V or -40V) on the RX lead
and battery return (BRTN) on the TX lead to power the terminal.
To implement it, install one jumper plug across the RX and PWR
pins, and one across the BRTN and TX pins as shown in
18 "Jumper plug settings for reverse power on the TX and RX
leads" (page 63).
Figure 18
Jumper plug settings for reverse power on the TX and RX leads
• No power on the TX and RX leads. This option applies when
the terminal is powered locally with an adapter provided with the
terminal. It also applies when a SILC DSL is used for trunking.
Remove the jumper plugs and store them on J1 to implement
this option.
Insert the SILC or UILC into the selected card slot and lock it in place.
