Preface
Scope
This manual describes the functions and features of the FOCUS line of communication
equipment. It is intended primarily for use by engineers and technicians involved in the
installation, operation, and maintenance of the FOCUS system.
Equipment Identification
The FOCUS equipment is identified by the catalog number on the FOCUS chassis
nameplate. You can decode the catalog number using the Catalog Number Table in
Chapter 2. The catalog number identifies only the chassis and common equipment. It
does not identify the channel modules installed.
Production Changes
When engineering and production changes are made to the FOCUS equipment, a
revision notation is reflected on the style number and the related schematic diagram
(available upon request). For the current style number/revision level of any FOCUS
equipment, please call us.
The default password for initial FOCUS setup
is focus1. You may change it after setup.
