ESI-50L Programming Manual Hardware overview/installation
A.1
General description
The ESI-50L Communications Server offers the small business an all-in-one communications system including
not only phone service but also voice mail and automated attendant. The system itself is housed in a surprisingly
small case that is wall-mounted in the telephone equipment room. An external, wall-mounted power transformer
powers the system. Standard system features include voice mail, automated attendant, external paging interface,
and extensive call coverage features (such as off-premises “reach-me”).
Important: References throughout this manual to separate PROGRAM and HELP keys are valid for only the 48-Key
Digital Feature Phone. On either the 24- or 12-Key Digital Feature Phone, the two keys are combined into
one PROG/HELP key, which is to be used in place of the separate keys.
Telephone system features
The ESI-50L has a four-line, eight-station, two-analog-port configuration.
• Impressive expansion capacity — Handles up to 16 CO lines and up to 32 stations.
• ESI Feature Phones — Compact and stylish, yet rugged, the 48-Key Digital Feature Phone and the 24-Key
Digital Feature Phone each include a high-quality speakerphone, an informative multi-functional display, and a
specially designed key layout with several dedicated keys to minimize or eliminate the need to memorize
codes. An Expansion Console is available for the 48-Key Digital Feature Phone; and each 48-Key Feature
Phone model includes an integrated headset jack. ESI also offers the 12-Key Digital Feature Phone with
similar design and basic functions. At least one 24- or 48-Key Digital Feature Phone must be purchased with
each system. Also available: ESI’s Digital Cordless Handsets. For more details about ESI phone models, see
the ESI Communications Servers Hardware Installation Manual (ESI document #0450-1049).

originate conferences.

time of the 911; also sounds a warning tone at the operator station and displays, for example:
