NSTALLATION
Reduced Installation Time
The Electra Elite IPK II 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 II 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 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 II 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. Full use of each KSU, before adding another,
reduces hardware requirements.
Resident System Program
A Resident System Program is provided when the system first receives
power. The CPU scans the KSUs and recognizes the ETUs and Multiline
Terminals that are connected to the system. Standard (default) values are
assigned in the System Program for all system and device parameters to
allow the system to operate immediately after initialization, before
programming is done.
