Paging Encoder
The Digital Tone Remote is equipped with a versatile, built-in, paging encoder. This
provides an easy method of selecting specific field radios and pagers for receiving alerts
and voice pages. The encoder supports Two-Tone (both 100- and 1000-call), DTMF (all
16 tone pairs), Five-Tone signaling (EIA, CCIR, ZVEI tone groups), and Pulsed-Tone
Dialing. Since it is built-in to the remote, it saves desk space in the dispatch area and
eliminates extra wiring and interface problems during installation.
One of the most unique features of the encoder is a page-by-name database. As soon as a
pager code is entered, the name of the person assigned to that pager appears on the display
to verify the selection. If the operator does not know the pager code to begin with, he or
she can quickly scroll through the whole list of names in the database until the right choice
is found. The encoder is ergonomic and easy-to-use even during emergencies.
To further support emergency applications, up to 10 fixed paging stacks can be pre-
programmed into the Digital Tone Remotes. Like a telephone speed-dial number, a stack
page is a sequence of pages (up to 10 pager codes) sent one after the other, which is
initiated with no more key strokes than an individual page.
Operator Interface
An operator has two ways to transmit. The operator may simply press the TRANSMIT
key on the deskset and begin talking. The Digital Tone Remote picks up his or her speech
on its built-in electret microphone and an automatic level-control maintains proper gain.
The operator will hear the receive audio from the base station over the deskset's built-in
speaker.
For more private conversations, the operator can use the handset. Lifting the handset out
of its cradle automatically mutes the deskset speaker and microphone, and shifts those
functions to the handset. The TRANSMIT function is also shifted to the press-bar on the
handset. Everything is automatically shifted back to the deskset when the handset is
returned to its cradle. One exception to this automatic control swapping is the PAGE
function. Pages can only be made using the TRANSMIT button on the deskset, regardless
of whether the handset is off hook or not.
The Digital Tone Remotes also provide connections inside the deskset to support
applications requiring external desk microphones, or headset/footswitch combinations.
Liquid-Crystal Display
A high quality LCD display provides for both ease-of-use and makes the maximum
amount of information available to the operators. For quicker and more secure frequency
selection, each frequency can be displayed with an accompanying text string. For page-by-
name purposes, text strings can be assigned to individual pager codes.
To provide a visual indication that the system is operating at adequate volume levels, VU
meter is included on the display for both receive and transmit levels. For further
