General features
A line module generally contains two interfaces. One exception is the module S
0
,
which contains one interface (but which carries two calls at the same time) and combined
module of external and internal line. Modules are equipped with overvoltage protection
and can be fitted to the motherboard or extender module in any order. All modules are
equipped with an identification system allowing the program of the PBX to ascertain the
concrete configuration immediately after switching on. All module connectors contain two
pairs of blanked holes (without contacts). This measure prevents the incorrect insertion of
modules.
All modules can be fitted up to the maximum number of vacant positions (12 = 6
motherboard + 6 extender module).
RJ45 connectors for connecting local circuits are a part of line modules. The
module is secured against movement by a screw in the connected strip.
