Terminals that are available in 8-line, 16-line, and 32-line capacities
and offered as display and non-display terminals. A 2-line
non-display terminal, 60-line Attendant Console, and a variety of
cordless terminals are also available.

A customer with existing Electra Professional terminals can easily
connect them to the Electra Elite 48 system to provide inexpensive
migration. Most Electra Elite 48 system features are available with
the Electra Professional Multiline Terminals.

The Electra Elite 48 system supports a wide range of additional
equipment including Single Line Telephones, external speakers,
facsimile machines, external microphones, and headsets that can
be connected to the system to accommodate individual customer
needs. Figure 1-1 System Configuration Example shows a system
with standard and optional equipment (some locally provided).
