Features Common to IP and Digital Inter-Tel Endpoints
Although their basic technologies and network connecting methods differ, IP and digital Inter-
Tel endpoints share both some physical characteristics and software features. For example,
both types of endpoint possess similar LCD windows, Call buttons, and feature buttons. They
share a common data structure, data entry fields in DB Programming, and call processing fea-
tures. The following sections describe important similarities of IP and digital Inter-Tel end-
points.
Direct Station Select/Busy Lamp Field Units
The Inter-Tel 5000 platform supports two 60-button DSS/BLF Units and one 50-button model.
Although you can use either type of DSS/BLF Unit on any of the endpoints, the type of end-
point determines which is the more appropriate unit to use.
• With Executive Display, Standard Display, Professional Display, and Associate Dis-
play Digital endpoints: PC Data Port Module (PCDPM)-equipped Executive, Profes-
sional, Standard, and Associate Display endpoints may have up to three 60-button DSS/
BLF Units connected to them. Up to twenty 60-key DSS/BLF Units can be installed on
the system. Each unit is powered by a 450 mA AC transformer and connected to the
PCDPM installed in the endpoint. The 6-rows-by-10-columns model, part no. 550.4200,
is designed for Executive Display and Standard Display endpoints, and the 12-rows-by-
5-columns model, part no. 560.4000, is designed for Professional and Associate Display
endpoints.
• With Model 8520 and Model 8560 endpoints: PCDPM-equipped Model 8520 and
Model 8560 endpoints support up to three Model 8450 50-button DSS/BLF Units, part
no. 550.8450. Up to 20 of the 5-rows-by-10-columns DSS/BLF Units can be installed
on the system. Each unit is powered by a 450 mA AC transformer and is connected to a
PCDPM installed in the endpoint.
Model 8614 Mini-Direct Station Select Unit
The Mini-DSS Unit is programmable and provides one-button access to 16 extension numbers
and/or feature buttons or resources. The Mini-DSS attaches to an IP Model 8660 or to digital
models 8520 or 8560 and does not require a PCDPM or an AC transformer. Mini-DSS buttons
contain LEDs that light or flash depending on the status of a station or the button’s program-
ming. For details about the LEDs, see “IP Endpoint Flashing Light Indicators” on page 81.
