5. Insert the SILC or UILC into the selected card slot and lock it in place.
6. Observe the behaviors of the LED on the faceplate of the MISP to determine its
7. Repeat the steps in this procedure for each SILC or UILC being installed.
Removing the SILC and UILC
1. Hold the card by its card-locking devices. Squeeze the tabs to unlatch the card-
2. Carefully disengage the SILC or UILC from the backplane connector, and slowly
Installing the PRI hardware

• 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

leads
on page 60.

• 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.
