Power Supply Unit (P/N 80005/A)
Digital Station Card - 16DSTU (P/N 80021/A)
NEC America
DS1000/2000 Correspondence Course
Card-based DC power source
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.
Extension Circuit Types
00 = uninstalled
02 = 22-button display
09 = 34-button super display
21 = 2OPX
Default = 02 (all stations set as a 22-button display)
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.
DS2000 System Hardware
01 = 22-button standard
06 = 34-button display
10 = door box
