SmartNode 1000 and 2000 Series Getting Started Guide

Operating modes

All four ports can be used in NET or USR modes.
• A NET port is connected to an ISDN terminal, i.e. a telephone or a PBX.
• A USR port performs user side signaling and the pin out corresponds to an ISDN terminal.

S-Bus line power

Some ISDN terminals are powered through the S-Bus. This is usually the case for ISDN phones but not for
PBXs. If you want to connect such a terminal directly to a port of the IC-4BRV-8V, you must install a PM-
48V-INT (or PM-40V-INT) power supply module. Two steps are required to provide S-Bus line power:
• Install an internal Line Power Module PM-48V-INT (or PM-40V-INT). This is described in section
"Internal PM-48V-INT or PM-40V-INT line power module installation"
• Configure the IC-4BRV-8V card's jumper settings. This procedure is described in the following paragraphs.

Line power jumper settings

A set of jumper pins determines how power is supplied to the BRI ports. The jumper pin block is located on
the IC-4BRV-8V interface card underside (see
IMPORTANT
Interface cards descriptions
figure 25
Power output on all ports is configurable. BRI ports of the IC-
4BRV-8V configured in USR mode must not supply line-power.
Set the jumpers so that line-power is only supplied on those ports
configured in NET mode, i.e. where you want to connect line-
powered ISDN terminals.
The jumpers are not accessible when the IC-4BRV-8V card is
installed, you must set the jumpers before installing the card in
the SmartNode 2000 Series device.
