Enhanced 911 Service (E911)
The Toshiba Strata DK forwards 911 and 9+911 calls to designated ports to interface with external
third party adjunct translation equipment designed to handle them. The Strata DK provides up to
two QSTU2, KSTU2 or RSTU2 ports (standard telephone ports) to receive these calls and send
them to the third party E911 adjunct equipment along with the specific directory number of the
emergency calling station.
The Strata DK sends the telephone DN to the telephone company’s 911 tandem switch that
forwards the call to the proper Public Safety Answering Position (PSAP) where it is matched up
with a central Automatic Location Information (ALl) database to provide enhanced information to
the PSAP dispatcher.
Interface between the third party adjunct equipment and the E911 tandem CO must be via special
Centralized Automatic Message Accounting (CAMA) trunks. (Ordering of these specialized
trunks is done through a special ordering desk with your local phone company.)
Important!
●
DID numbers: In many cases, a DID service is the only way to provide a unique number
(CESID) for each station that is recognizable by the telephone company.
●
In order for this feature to be effective, 911 and 9+911 calls must be dialed from a DKT [DN]
or single-line telephone. 911 calls originating from a [PhDN] CO Line or Pooled Line button
bypass the adjunct equipment and go directly to the CO exactly as dialed.
E911 System Installation
1. Ensure that the QSTU2, KSTU2, RSTU2, RDSU/RSTS or PESU PCB is installed in the
Chapter 9 – Universal Slot PCBs
or each DK14 and DK40i installation section.
2. Connect the E911 system to the selected QSTU2, KSTU2, RSTU2, RDSU/RSTS, or PESU
standard telephone port. (See Chapter 1 – DK14 Installation, Chapter 3 – DK40i Installation,
Chapter 10 – Universal Slot PCB Wiring
for wiring/interconnecting details.)
3. Program the Strata DK system for the required E911 features. (See
4. Install E911 external system per the manuals supplied by the vendor selected and used for the
interface.
E911 Programming
Program *10: Selections 11 and 12 assign the RSTU port to be used for E911 Service. Selections
91 and 92 assign an inter-digit timer for valid dialing and a delay timer before the station number is
sent to external E911 equipment.
➤
Remove the [DN] assignment for ports assigned to E911 so that someone calling a station
number will not accidentally call 911.
