INTER-TEL AXXESS MANUAL VERSION 11.0 – May 2008
I. DIGITAL DISPLAY PHONE DESKTOP INTERFACE
NOTE:
The Desktop Interface software license is required if attaching Desktop Interface
devices to a digital phone.
12.100Desktop Interface is a station-level communications protocol that allows a PC, attached
to a PCDPM on an Executive Display, Professional Display, Standard Display, Associate Dis-
play, Model 8520, or Model 8560 Phone, to emulate a phone for call handling. This protocol
allows devices such as PC phones, operators' consoles, ACD supervisors, and integrated con-
tact management tools to be developed for the Inter-Tel phone system.
12.101There can be as many Desktop Interface devices on the system as there are Executive
Display, Professional Display, Standard Display, Associate Display, Model 8520, and/or Model
8560 Display Phone circuits. The only limitation is on Desktop Interface devices that require
DSS/BLF status updates (such as operators' consoles). The system can support up to 20 DSS/
BLF status requests from external devices at one time. Therefore, if the device requires contin-
uous DSS/BLF status updates, only 20 can be installed on the system at one time. Devices that
require one-time or infrequent DSS/BLF updates are not limited by this capacity, except that
only 20 requests for updates can be processed at one time. There is a limit of four virtual DSS
devices per system because of the number of requests they require and the amount of informa-
tion that is shared with the system.

12.102Another Software license, System OAI, is a system-level communications protocol that
allows command-oriented tools to be developed for the phone system. System OAI is available
in two levels: Events and Third Party Call Control. System OAI Events provides call status
information to an external device. Its primary use is for automatic call distribution products
such as the Contact Center Suite. System OAI Third Party Call Control is a TSAPI protocol
that allows system command-oriented tools to be used on the phone system. Contact Inter-Tel
for more information regarding products and development materials for these features.
NOTE:
Level 2 System OAI applications can be used on networked systems. Note that some
System OAI Level 2 applications must be used in conjunction with the CT Gateway and/or
Transceivers to process the network information correctly. For high-capacity systems, such as
an ATM-based system, the CT Gateway is recommended. In addition, version 8.0 or later soft-
ware requires CT Gateway version 3.0 or earlier. See the CT Gateway Installation Manual for
more information.
