Connector Module
The S
2M
connector module allows you to operate an OpenCom 130/150 on a
primary rate access. This access provides up to 30 voice channels. You can also use
the S
2M
port to network two systems, e.g. in order to use the OpenCom 130/150 as
a subsidiary system or DECT server.
Note on DECT applications in conjunction with S
2M
If an S
2M
connector module is installed in the OpenCom 130/150, please consider
the following restriction for DECT applications:
It is not sufficient, to install a U
pn
interface card (e.g. “4 x U
pn
”) into slot 2 (or into
slot 3 with the OpenCom 150). In every case, you need to run a U
pn
interface card
(“4 x U
pn
”, “8 x U
pn
” or “2 x S
0
and 6 x U
pn
”) in slot 1 in order to operate DECT appli-
cations properly.
Note: The maximum cable attenuation between the
OpenCom 130/150 and the other system (NT or telephone
exchange) must not exceed 6 dB. This corresponds to a
length of approx. 150 to 200 m, depending on the type of ca-
ble used.
