Power Supply Unit (P/N 80005/A)
● Card-based DC power source
Digital Station Card - 16DSTU (P/N 80021/A)
● 16 digital stations
● Installer-friendly 8-pin (4 pair) modular jacks
● Each 8-pin modular jack supports
four (4) digital stations
● No programming required to install the card,
but stations need to be identified by circuit type
in Program 1801 - Extension Port Description.
With software 2.02.14 or higher, Automatic
Telephone Type Detection is available which allows digital station ports (on
installed and programmed PCBs) to automatically detect the type of con-
nected device when the keyset, 2-OPX Module or Digital Door Box is
plugged in. This speeds up installation because you no longer have to individ-
ually set circuit types in 1801 - Extension Circuit Type. For example, if you
plug a 34-Button Super Display into extension 300, the system automatically
changes the circuit type to 09 and moves the Operator Call Key to program-
mable key 24.
Note: In DS2000, it is still necessary to install and configure PCBs in 9902 -
Slot Assignment before Automatic Telephone Type Detection is available.
Extension Circuit Types
00 = uninstalled 01 = 22-button standard
02 = 22-button display 06 = 34-button display
09 = 34-button super display 10 = door box
21 = 2OPX
Default = 02 (all stations set as a 22-button display)
