INTRODUCTION
This manual describes the installation, configuration,
and operation of the Enhanced Local Interconnect (ELI)
option. A companion manual, the Global Telephone
Interconnect (GTI) Configurator user's guide (LBI-39077),
describes how to use the GTI Configurator software to
configure the GTI units.
Although the objective of this manual is to provide
information in the order it should be needed, completely
read the applicable section before starting the installation or
configuration.
