IMPORTANT STRATA DK8 AND DK16 PORT INFORMATION
General
There are two types of ports in the STRATA DK8 and DK16 system: Physical Ports and Logical Ports.
This distinction of ports gives customers greater mobility in relocating their stations (telephones).
Physical Ports and Logical Ports
Physical Ports can be defined as the actual system hardware—PCB circuit, wiring, and RJ-11 jack that
stations plug into. Logical Ports are attributes associated with a station (telephone)—station intercom
number, Speed Dial numbers, and the complement of features assigned to the station in system software
programs. A Logical Port is always associated with a Physical Port.
Physical Ports can be considered as fixed; they cannot be moved unless a PCB is removed from the
KSU, Base or Expansion Unit. Logical Ports, though, are not fixed. They can be moved from one Physical
Port to another. It is important to note that Logical Ports can only be moved to related Physical Ports. For
example, you can move a digital telephone (Logical Port) to another digital Physical Port (circuit), but you
cannot move a digital telephone to an electronic telephone circuit Physical Port.
When entering ports into program data, except for Program 01, always enter the Logical Port number.
