External Alerter interface
The External Alerter Bo ard provides an interfa ce to standard remote ri nging
devices, such as a ringing unit, installed in a location separate from the
telephone. The External Alerter interface is not the remote ringer itself, but
provides access to standard, off-the-shelf remote ringing devices. The Alerter
Board requires additional power. See “Power requirements” on page331.
You can program the External Alerter interface to activate a ringer (or light)
when the telephone rings or when the telephone is in use (off-hook).
For information on installing and setting up the External Alerter, see “Add-
on modules” in Telephone and Attendant Console: Installation (553-3001-
215).
Brandline insert
The telephone contains a removable insert designed to accommodate custom
labeling. You can order blank Brandline Inserts and have a printer silk screen
your company logo on them.
