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, 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 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 interface card underside. See the series of illustrations, which follow.
Note
Interface cards descriptions
When the line power module is installed and operating, ports 0
and 1 are always supplied with 40V power. Power output on
ports 2 and 3 is configurable. You must not supply power to a
port configured in USR mode, i.e. connected to an ISDN NT.
Supply power only to those ports configured in NET mode where
you want to connect line-powered terminals.
The jumpers are not accessible when the IC-4BRV card is installed,
you must set the jumpers before installing the card in the SmartNode
2000 Series device.
