• The maximum AltiContact Manager extension and trunk traffic
anticipated
• The number of simultaneous client software connections
Table 7, “Individual Board Power Requirements,” on page 2-13 shows the
AltiContact Manager system requirements guidelines depending on the
number of AltiGen boards that will be installed.
Proper Grounding and Loop Current
Proper grounding is essential for any PBX system. This is a simple but
very important step and is highly recommended. Run a wire from the
server chassis to earth ground. Don’t wait for a problem to arise before
taking this step. Make sure this is one of the first things you do before
turning the AltiGen system on.
Also, check the loop current on incoming trunks before connecting to any
AltiGen boards. The desired loop current measurement is 25mA–28mA.
This is another essential step to ensure proper operation of AltiGen
systems. For more information on loop current issues, please refer to the
toolbox in the tech support section of AltiGen’s web site at
http://support.altigen.com.
Uninterruptible Power Supply (UPS)
Using a UPS prevents power fluctuations and surges on power sources
from utilities. Windows NT files can be corrupted as a result of power
failure or improper system shutdown.
Caution: Corrupted files may not be repairable and may require re-
installation of Windows NT and AltiContact Manager. To
protect your system from surges and power outages, it is
strongly recommended that an adequate UPS (providing
between 600VA and 1000VA) and power surge protector is
used with the system.
Operating Environment
Before you set up and use the system, consider the environment in which
the system will reside:
• Choose a work surface large enough to accommodate the entire
system.
