Fax capability
Some voice resources provide fax capability. TeleVantage does not use the fax capabilities of
these voice resources, but will use these voice resources for normal voice resource activity such
as playing or recording voice files. Note, however, that fax-capable voice resources on Intel
Dialogic DM3 boards are not used in this way by TeleVantage. Fax-capable voice resources can
be used by third-party applications.
FSK capability
Some voice resources provide the ability to transmit and receive frequency shift keying (FSK)
signaling which TeleVantage uses to send Caller ID or visual message waiting information to
CLASS phones.
CSP capability
Some voice resources provide continuous speech processing (CSP) capability. TeleVantage
does not use the CSP capabilities of these voice resources, but will use these voice resources for
normal voice resource activity such as playing or recording voice files. CSP-capable voice
resources can be used by third-party applications.
Conference resources
Conference resources provide conferencing capabilities. For details on how TeleVantage uses
conference resources, see Appendix A.

About slot types
The type of slot and number of slots required vary by board. A particular board may require 1
or 2 ISA or PCI slots.
There are 2 voltage specifications for PCI slots, 3.3 and 5 volts. 3.3 volt slots are sometimes
called PCI-X slots. Some PCI boards require 3.3-volt slots while others require 5-volt slots.
Universal PCI (UPCI) boards can be installed in either slot.
