The total number of components you can install and connect to your system
depends on power supply capacity and the System Load Factor. Use the following
Configuration Guidelines and System Load Factor table when configuring your
system. With the DS2000, depending upon your hardware and system software,
there may be limitations on the number of PCBs allowed in the system or the slot
in which they can be installed.
You may find that the default setup for your system is adequate for your needs.
Also keep in mind that with the DS2000, only two 16DSTU's can be supported
per power supply, even if the system load factors are not exceeded.
Using the factory installed default configuration, your DS1000 system provides:
Trunks
Digital Extensions
Analog Extensions
Analog Door Boxes
Relays
Page Output
Music Input
System Load Factor Calculations
The combination of extensions, 2-OPX Modules, Digital Door Boxes and DSS
Consoles you can connect to your system may be limited by the System Load
Factor. Use the DS1000 System Load Factor Calculations chart which follows to
verify your system's configuration.
