Computer system requirements
Run Voice Services on a dedicated machine. This machine must meet the following minimum specifications.
 NotesThese specifications are the minimum requirements only. With added load, other processes configured on the same machine, or large systems, exceed these specifications.
If you prefer to run Voice Services on the same machine as your FirstClass server and/or Internet Services, these minimum specifications must be added to the system requirements of the other components. Minimum system requirements for the FirstClass server, Internet Services and the FirstClass client can be found at www.firstclass.com/products/SysReq/.
� Windows 2000 or Windows 2003
The machine will have a high-end graphics card and a network card installed.
This machine can be gatewayed to a FirstClass server running on a Mac OS.
� processor speed: 1 GHz single processor
� 10 GB internal hard disk space
� 512 MB RAM per T1 PRI span (23 B-channels, 1 D-channel)
� one 33 MHz PCI slot available for each Dialogic voice and fax card
If you have the universal voice cards, you can use 3.3 or 5 volt slots. Non-universal voice cards and DMF240 fax resource cards require 5 volt slots.
� FirstClass client installed on the Voice Services machine.
This must be from the same release as your server.

T1 PRI and E1 interface
If your configuration includes configuring an SMDI line to set MWI, you will require a serial port for the incoming SMDI line from the CO.
You will need a T1/E1 line configured to the following specifications:
Frame mode ESF (Extended super frame)
Line coding B8ZS (Binary 8 zero substitution)
Switch Nil/Null (no switch)
Signal type NI1 or NI2
Voice/Fax Board combinations and configuration
Multiple boards and combinations of voice and fax boards are attached together by a CT bus cable.
Each Dialogic board has a rotary switch, which must be set manually during installation. The following table explains the settings to use, dependent on the hardware configuration. The rotary switch is located on the board. See Dialogic installation instructions shipped with the board for information for further information.
