External Amplified Speaker
System Availability: All systems
The External Amplified Speaker (HESB) is a six-inch, three-watt speaker with a three-watt
amplifier built into a wooden speaker box. The amplified ringer can be used to:
• Amplify the ringing on a digital telephone.
• Provide a paging amplifier/speaker.
• Create an amplified talk-back speaker arrangement in an area where a telephone is not needed.
The HESB is installed as a speaker and connected to a door phone unit that is used as the talk-
back microphone.
Amplified ringing can improve call handling in noisy areas where non-amplified ringing on a
phone may not be heard.
A paging speaker ensures that paging announcements can be clearly heard throughout an area. In
an area where a DKT is not needed, a talk-back speaker provides a cost-effective communications
solution.
The number of HESBs that can be installed per system depends on the function of the HESB. Any
number of HESBs can provide loud ringers for digital telephones. Only one HESB can be installed
if it is used as a paging or an amplified talk-back speaker.
Note A BHEU interface and an HESC-65A cable are required for each digital phone that has a
loud ringing bell. IP telephones require HESC-65A, but not BHEU to support External
Amplified Speaker. A 3000- or 2000-series digital telephone that has been upgraded with a
data interface unit can be upgraded with the BHEU options, but older telephone models
cannot.
Flash Button
System Availability: All systems
This is an optional button that can be assigned on digital telephones. It can be used either to
disconnect a line and regain CO dial tone, or to gain access to Centrex features. The timing choice
is set system wide through system programming. Standard telephones can dial an access code to
flash Centrex lines.
Flexible Line Ringing
System Availability: All systems
CO line ringing can be assigned to ring a specified [DN] on a station, a [DN] appearing on
multiple stations, a Pilot [DN], a direct appearance of the CO line, a Pooled appearance of CO
lines, or Group CO line appearance. These assignments direct the ringing of the incoming call
based upon the three Day/Night Modes of operation and offer immediate and two delayed ringing
parameters. The delay parameters are assigned for each incoming Line Group.
