Switch Group Interface

The switch group 1 routing element can be controlled via control inputs ME1 and
ME2 on the OI-2DOOR special card. Control is effected using external switches
(door contacts, time switches, etc.) which switch the appropriate inputs to the
PBX ground (GNDC). The signal no-load voltage is approx. 40 VDC, the short-cir-
cuit current approx. 4 mA.
Control of the switch group using the control inputs takes priority over control
using */# procedures.
There are no special requirements for the cables.
