18 Section 2: Components
The total number of components you can install and connect to your DS2000 system depends on
power supply capacity and the System Load Factor. Use the notes below and the System Load Fac-
tor Table to calculate your system's capacity.
Fixed Slot (01.nn.nn) software is only available with 4 slot cabinets.
Fixed Slot software is no longer available, but you may encounter it in existing installations.
DSTU PCBs can plug only into the first two slots. Do not install more than 2 16DSTU PCBs
under any circumstances.
An ASTU PCB can plug only into the second slot (in place of the second DSTU PCB).
ATRU PCBs can plug only into slots 3 and 4.
Maximum configuration is 16 trunks, 32 extensions, and 48 ports.
Use the System Load Factor Table only if your system has DSS Consoles and 2-OPX Modules.
Universal Slot (02.nn.nn) software is available with both 4 and 8 slot cabinets.
4 Slot Cabinets
Do not install more than 2 16DSTU PCBs under any circumstances.
The first 16DSTU PCB you install must be in the first slot.
You can install up to 40 extensions maximum, as follows:
(2) 16DSTU PCBs = 32 digital extensions
(1) 8ASTU PCB =
You can install up to 24 trunks maximum, as follows:
(3) 8ASTU PCBs =
Maximum configuration is 48 ports.
The total of all extensions and trunks installed cannot exceed 48.
Always use the System Load Factor Table to check your system configuration.
