Response Messaging
This feature allows a user to reply in a non-verbal manner to a voice announce or
tone-signaled intercom call or to a subdued off-hook voice announce call if the intercom
caller is using an LCD speakerphone. A station user can press a programmable button in
response to an intercom call and send a message to be shown on the display of the calling
station. Response messages are pre-programmed by the attendant and later stored by
station users at programmable buttons on their individual stations as need dictates.

Remote Programming And Administration
Both remote class of service programming and the transmission of SMDR data for
printing are available through serial data ports. The system supports X-on X-off terminal
control codes as well as a DTR signal for handshaking. The system data communications
operates per the popular XMODEM protocol. The database can be uploaded or
downloaded, error free, from or to a remote computer that is running software that
supports the XMODEM protocol. The two serial data ports allow VDT programming
(either local or remote) to be conducted through one port at the same time that the other
port is being used to send SMDR data for printing. VDT programming of the system is
menu driven.

Ringer Volume Control
DigiTech, Impact, and Impression telephones have a ringer volume control that
telephone users can operate to adjust the loudness of the ringer at his or her station.
Ringing
Auxiliary Ringer Interface
The auxiliary ringer interface provides “dry-contact” relay closures which track the
ringing pattern whenever the system sends ringing to a programmable destination.
Programmers can program relay control to be activated when the system sends ringing to
station port 17 or to the paging port.
When programmed for station port 17 ringing, an installer often uses an external device
to provide loud ringing. When programmed for paging port ringing, an installer often
installs an external paging amplifier to sound the rings. The system supplies ringing tones
to the paging port along with the relay closures. It can send the ringing tones to the input
