Description

TB9400/TN9275 Installation and Operation

© Tait International Limited May 2023

Offline Mode

Offline mode allows a maintenance engineer to carry out tasks that can not
be done while the base station is in service - such as activating firmware or
running diagnostic tests.

1.8.3

Intermodule Communications

A system control bus and a subrack interconnect board link the modules in
the subrack and carry alarm and control signaling between the reciter and
the other modules, as shown in

.

Specific configuration settings for dual base stations are described in

“Recommended Configuration Settings” on page 66
