ECTION NSTALLATION
Reduced Installation Time
The Electra Elite IPK System uses modularity and connectivity throughout to reduce
installation time and labor. The modular Key Service Units (KSUs) are installed
vertically for the Electra Elite IPK system. Most internal connections are made with
plug and jack.
Reducing the labor required for installation, modularity and connectivity increase
reliability. No wiring changes are made in the KSUs and all connectors are factory
tested.
The power supply unit and the battery backup unit are installed in the KSU and allow
for easy connection to extra battery backup units. All circuits installed in the KSUs are
located on printed circuit boards that plug into prewired connector slots. Connection
for voice and data between the KSUs is provided by a single ribbon cable between
the basic and expansion KSUs. Voice and data are transmitted between KSUs using
an EXP-U( ) ETU in the Electra Elite IPK system.
Connection to telephones, outside lines, and other external devices is made using
telephone cable connectors. A music source for Music on Hold is connected by
standard audio equipment plugs.
Universal Slots
Using Universal Slots maximizes flexibility by allowing installation of any ETU into any
interface slot (except the MIFA/MIFM-U( ) ETU and SPE(M)-U( ) ETU that can only be
installed in the AP slot, slot S1, or slot S2 of the first B64-U( ) KSU. Full use of each
KSU, before adding another, reduces hardware requirements.
