DS2000 System Configuration
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.
Notes for DS2000 Fixed Slot Software
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.
●
