HARDWARE SPECIFICATIONS AND INSTALLATION
1.1 General Information
The Electra Professional Level II is a fully digital system serving a maximum of 56
outside (CO/PBX, DID, Tl/FTl, and Tie) lines and a maximum of 56 terminals. The
Electra Professional Level II Advanced system serves a maximum of 64 outside lines and
a maximum of 96 terminals. Both systems provide for flexible configuration, allowing
the customer to purchase only what is needed. The Level II basic cabinet can
accommodate a combined total of 40 ports, consisting of outside lines and/or telephones
and/or other options. As a customer’s business grows this system can be expanded to
accommodate a combined total of 64 ports. The Level II Advanced system basic KSU can
accommodate 64 ports. Each of the two available expansion KSUs also support up to 64
universal ports. Additional equipment such as: Single Line Telephones, external
speakers, voice mail, facsimile machines, etc., can be connected to these systems to
enhance their capabilities. (Figure l-l - OutsideView ofthe Electra Professional Level II
KSUs and Figure 1-2 - Outside View of the Electra Professional Level II Advanced
KSUs.)
This chapter is designed to provide the technician, installing the Electra Professional
Level II or Level II Advanced, a comprehensive explanation of the systems specifications,
hardware, and installation procedures. The technician should read this chapter in its
entirety before installing the system. This will enable more efficient installation and
cut-over.
