PRI Board
Board Description
The PRI board contains one or two (depends on the part number) ISDN interfaces and
PCM bus timing circuits. PRI 1 is designed as an internal interface (with an activated
LCR function) and PRI 2 as an external interface (all calls from the port are always
routed to PRI 1). The interface can work in the MASTER or SLAVE mode (set the PRI 1
mode using the configuration tool and PRI 2 has always the opposite mode). The
output can be configured as TERMINAL (TE) or NETWORK (NT) by jumpers (switching
of wires – for software switch you have to use the configuration tool!). The settings of
these jumpers HAVE TO match the PRI configuration – two NT and TE modes will
cause malfunction of the PRI board or back-up connection* ! The board is designed on
a 4-layer PCB of the size of 160x100mm. There are also 5 (or 8 in 2ISDN PRI) board
status indicators, which are located on the front panel.
* The PRI board contains four switches (can be deactivated by jumpers), which
provide hardware connection between PRI 1 and PRI 2 in case the system is switched
off or inoperative.
Tip
The LED statuses provide basic information on the ISDN interface only. For
details on the ISDN interface state refer to the configuration tool.

Flashing: B-channel in restart
Light off: No active call
Status of ISDN layer 2 on PRI 1 (2) interfaces:
Shining: Layer 2 successfully established
Flashing: Layer 2 in the establishing process
Light off: Layer 2 disconnected
Status of ISDN layer 1 on PRI 1 (2) interfaces:
Shining: Layer 1 successfully established
Flashing: Layer 1 in the establishing process
Light off: Layer 1 disconnected
Physical RJ45 connectors for ISDN PRI 1 and PRI 2 interfaces
Before you plug in your ISDN connection please check whether
the wiring configuration matches the ISDN connection
requirements!
