SECTION 3 SYSTEM DESCRIPTION
The Electra Elite IPK uses a universal port concept. These ports support telephones,
outside lines and other circuits and devices. The assignment of ports is flexible, but
the system configuration determines the number of ETUs
that can be installed. The
maximum number of devices that can be supported by the system are shown in Table
3-1 Maximum System Capacities for Station Interface ETUs on page 3-1, Table 3-2
Maximum System Capacities for Trunk Interface ETUs on page 3-8, Table 3-3
Maximum System Capacities for Application Interface ETUs on page 3-15, Table 3-4
