Digital Phone Desktop Interface
NOTE: Your software license must include the appropriate premium feature(s) to use Desktop
Interface and System OAI features.
Desktop Interface is a station-level communications protocol that allows a PC, attached to a
PCDPM on a Model 8560, Model 8520, Executive Display, Professional Display, Standard
Display, or Associate Display, to emulate an Inter-Tel phone for call handling. This protocol
will allow devices such as PC phones, operators’ consoles, ACD supervisors, and integrated
contact management tools to be developed for the system.
There can be as many Desktop Interface devices on the system as there are Model 8560, Model
8520, Executive Display, Professional Display, Standard Display, and Associate 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 continuous 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 Attendant Consoles
per system because of the number of requests they require and the amount of information that
is shared with the system.
Another Premium Feature, System OAI, is a system-level communications protocol that allows
command-oriented tools to be developed for the 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 Call Cen-
ter Suite. System OAI Third Party Call Control is a protocol that allows system command-ori -
ented tools to be used on the system. System software versions 6.0 and later do not support
Level 1 System OAI. Contact Inter-Tel for more information regarding products and develop-
ment materials for these features.
