If your console is model 25, check that the analogue interface connector on the console is
covered with a dummy plate. If not, install the dummy plate. The dummy plate is enclosed in
the packing box of the SV25 and SV35.

PROJECTING MODEL 25-A IN THE ISPBX
Projecting of model 25-A is done in the same way as all other analogue operator circuits. If
model 25-A replaces an already existing Analogue Operator Console no further projecting is
required.
If model 25-A must be added to an ISPBX, project the interface board in the same way as for
other Analogue Operator Consoles. To do this consult the appropriate system (OM or PE
commands) manuals.
