Wire the S
2M
port of the connector module to the NT or the other PBX
according to the following drawing. Make sure the RX and TX lines are crossed
over (connect the RX lines of the OpenCom 130 / 150 to the TX lines of the
other PBX).
Example of the wiring of the S2M port for two OpenCom 130 / 150s
On the OpenCom 150 the pressure terminal is a 5-pin connector. The addi-
tional terminal is used to connect the shielding of a shielded line. The shielding
has to be stripped as short as possible (approx. 3 mm).

If necessary, check to make sure that the NT is fed by its own power supply.
