Connections - elmeg C46e Description And Installation

Connections

Before installing your PABX at an ISDN connection, you must first decide what
type of connection (multipoint or point-to-point) you wish to configure as your
ISDN connection. This connection must be applied for at your network service
provider and then configured in the PABX as described in the section Program-
ming.
2.2.1 Terminals
The terminals can be removed from the soldered pins on the printed circuit
board (pcb). This allows you, for example, to switch user connections without
disconnecting the cables. In the as-delivered state of the PABX, the terminals
are not connected; they are included in a separate bag. To disconnect terminals
which are set, lift the terminal block up carefully using a small screw driver and
then remove the terminal. Ensure that you do not bend the pins.

2.2.2 ISDN connectors
The ISDN connectors (Western connectors, RJ45 connectors) are locked after
being plugged into the ISDN jack to prevent them from being pulled out. The
lever points in the direction of the pcb after being plugged into the PABX. To
unlock these connections (Figure 3) press on the small lever on the ISDN
connector while pulling the ISDN connector out.
