Toshiba DK40I 用户手册

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.

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 
accidentally dropping the 911 call attempt. This includes the 

+ROG

 button, so that the 911 

call cannot be put on hold.

♦

Press DN button and dial 911. When the user dials 911, the PDN releases from the internal 
connection and seizes the CAMA trunk.

♦

Off Hook and dial 911 (station has off hook selection of PDN in Program 32). When the user 
dials 911, the PDN releases from the internal connection and seizes the CAMA trunk.

♦

Off Hook and dial 911 (station has off hook selection of a CO line or line group in Program 32 
and has a CO 

/LQH

 or 

3RROHG/LQH

 buttons). When the user goes off-hook, the station will 

seize the normal CO line on the appropriate CO 

/LQH

/

3RROHG/LQH

 button. When the user 

dials 911, the normal CO line is dropped and an idle PDN or CAMA CO button connects to 
the CAMA trunk.  If an idle PDN or CAMA CO button is not available, the 911 call will be 
sent out the originally selected line without the station’s CESID information.

♦

Press DN button and dial 9+911 (no LCR, 9 is line group access code, station does not have 
CO 

/LQH

, 

3RROHG/LQH

 or 

&$0$

 CO buttons). When the user dials 9, the station will seize 

a “dial 9” CO line on its PDN button.  When the user dials 911, the 911 call will be sent one of 
two ways:  

♦

If the station does not have another idle PDN or 

&$0$

 CO button, the 911 call will be 

sent out the normal CO line in the dial 9 line group without the station’s CESID. 

♦

If the telephone has another PDN  or 

&$0$

 CO button, and it is idle, the first PDN will 

drop and the second PDN  or CAMA CO button will be connected to the CAMA trunk. 
911 plus the station’s CESID will be sent out the CAMA trunk.
