Absence and permanent conversion
The desk can be programmed with an absence and
permanent conversion facility whereby, in the absence
conversion mode,if a call is made to a receiver which is in
the rack, the call will automatically be transferred to a
second receiver. This is useful,if say,a consultant is on
holiday and all calls must go to his deputy. In the
permanent conversion mode,one of the receiver call
numbers is changed in the desk so that if the receiver is
called,the desk will automatically transmit the changed
number. This facility could be used e.g. if a receiver holder
is using a spare receiver whilst his own is out of order.
Multi-purpose coupler contact inputs
Up to 31 multi-purpose coupler heads,type LBB 5843/01
can be connected to this desk, giving it a capacity to provide
up to 992 input contacts for calls and other functions, and
up to 62 relay outputs. For more information on the multi-
