Station Considerations

Station Considerations
For configuration purposes, any device which is connected to a dedicated telephone circuit is 
considered a “station.” Although the words “telephone” and “station” are often used 
interchangeably in Strata DK40i documentation, devices other than telephones—such as Stand-
alone Data Interface units (PDIU-DSs)—should also be considered stations when configuring a 
system since they require a dedicated telephone...

Telephone Circuit (Port) Types
There are four types of telephone circuits to which stations can be connected: digital, electronic, 
and standard telephone circuits. Also, there are ISDN (S/T) type telephone circuits, terminal 
equipment (TE-1) and terminal adaptor circuits. 
Digital Telephone Circuit Connections
The Strata DK40i Base KSU and the PDKU2 PCB each provide eight digital telephone circuits. 
Each KCDU...

Electronic Telephone Circuit Connections
There are no electronic telephone circuits in the Base KSU, and none can be added to it. However, 
either the PEKU PCB, which has eight electronic telephone circuits, or the PESU, which has four 
electronic telephone circuits, can be installed in the Expansion KSU.
The following devices can be connected to electronic telephone circuits (see Table 2-10).
