Chapter 8 - E911; Operation Overview - Toshiba DK14 Programming Manual

E911
This chapter contains programming record sheets, along with specific instructions for
programming E911 CAMA trunks.
Enhanced 911 CAMA trunks apply to the DK40i, DK424, DK424i Release 4.3 and higher. The
RMCU/RCMS PCBs provide up to four CAMA trunk circuits. The RMCU/RCMS eliminates the
need for adjunct terminal adapter equipment for connecting to E911 CAMA trunks. For more
information on hardware, refer to the Strata DK Installation and Maintenance Manual.

Operation Overview

The DK E911 feature provides flexible dialing of 911 emergency calls. This allows users who are
not familiar with DK424 and DK424i dialing sequences to make an emergency call regardless of
how they dial 911 from Toshiba telephones. In all of the sequences below, the DK will seize an idle
CAMA trunk and send 911 plus the dialing station's Caller Emergency Service Identification
(CESID) over the CAMA trunk via MF tones.
Once a 911 call is started, most other buttons/keys on a telephone are disabled to prevent
