3.8 Button Mapping The Stations
(Non-Square System Configuration)
You can assign (map) every programmable button at each digital station to be line-select buttons so that
they provide access to outside lines; to be direct station select (DSS) buttons so that they provide quick
access to system stations; to be special purpose buttons so that they provide telephone users with
one-button access to features; or to be idle buttons so that they provide autodial locations for the station
user.
Three idle (unmapped) buttons serve as dynamic line buttons. Dynamic line buttons provide a location for
the system to temporarily assign a line appearance to a station that normally does not have that particular
line assigned to it. While a line is in appearance there, the user can perform any normal call handling
operations that he or she wishes to perform. The lines are identified as follows: B1, B2, and B3 on
DigiTech telephones (product codes 7700S, 7714X, and 7114S), B1, B2, and B3 on Impression
telephones (product codes 2022S, 2122S, 2122X, and 2101N), or L1, L2, and L3 on Impact telephones
(product codes 8012S, 8024S, 8112N, 8112S, and 8124S). Refer to section 4.4, Recording The Station
Configurations, for button illustrations.
When you map a button at a station port, press the corresponding button on the programming station to
select the button to be mapped. If you must map buttons at a station port while using a programming
telephone that does not provide a full complement of buttons, you can dial a 3-digit code to select a
button. The table below lists the 3-digit codes and their corresponding buttons.
