M-390-A Polling Controller. The Polling
Controller and one or more Line Sharing Switches work together as a system

utility applications. In this manual, LSS is used to indicate both switches.
The reference manual accompanying the LSS explains how to install, program,
test, and operate the LSS or SLSS and should be used in conjunction with this
manual.
