Downloading of Terminal Parameters
Programmable Terminals
The following information describes how maintenance software interacts with
terminal parameter downloading.
Terminal Types
a. 84xx multibutton digital voice terminals (8403D01A, 8410B, 8410D02A,
8434D01A) with optional expansion module.
b. 603A1 and 603D1 Callmaster terminals for telemarketing applications.
c. 302B1 and 302C1 attendant console.
Downloadable Terminal Parameters
The following parameters are downloaded to programmable terminals:
Nonvolatile Memory
Nonvolatile memory stores downloadable parameters in programmable terminals.
Once the terminal is downloaded, it is not be necessary to download it again, even
if power is removed from the terminal. If nonvolatile memory fails with power still
present, the terminal reverts to its default factory settings except for its
A-law/mu-law companding settings which are stored in RAM. If power is removed
after the nonvolatile memory fails, the terminal reverts to its factory default
settings.
NOTE:
The mu-law companding mode is assigned as a default setting at the
factory. For the United States, a programmable terminal can place calls
even though it has not been downloaded from the system.
