3.2.3 Converting Button Designations
When you first power a new system with no telephones connected, it defaults its station ports as
follows:
Software Type Telephone Type
Snnnn DigiTech 24-line telephones
Innnn Impact 24-line speakerphones
When you connect a telephone to a powered-up system or when you turn on the AC power to a
system after you have connected a telephone to it, the system automatically button maps the
telephone according to the type of software cartridge the system has. To change the button
mapping default, install a different software cartridge and master clear the system.
The buttons on Impact telephones are designated as L buttons; the buttons on DigiTech and
Impression telephones are designated as A and B buttons. Table 3–1 lists each A and B button
and its equivalent on an Impact telephone. The programming steps in this manual use A and B
button designations; if you are programming from an Impact telephone, you must use the proper
telephone programming overlay with the A and B designations. Telephone overlays are included
with the literature package for the digital telephone system. You can also find sample overlays at
the end of Chapter 4, Records.
