76 Strata DK General Description 6/00
Two companies have been identified that supply the E911 adjunct translation systems: Proctor and
Associates, Redmond, WA, (800) 824-9719; and Telident, Inc., Minneapolis, MN, (800) 536-4911.
Direct CAMA Connections
The DK424i E911 feature provides direct connection of CAMA trunks for flexible dialing of 911
emergency calls. This allows users who are not familiar with DK424i dialing sequences to make
an emergency call regardless of how they dial 911 from Toshiba telephones. 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.
ISDN Operation
The DK40i and DK424i can place E911 calls directly over ISDN Primary Rate Interfaces (PRI).
In the ISDN call setup for both cases, the Called Party Information will be “911” and the Calling
Party Information will be CESID.
For both Direct CAMA Connections and ISDN Operation, two packets are sent out the SMDR
port on each E911 call. The first packet will be sent immediately at the start of the call and the
second will be sent at the end of the call when the CAMA or ISDN trunk releases.
External Page Zones
The Strata DK40i can support up to four External Page Zones and DK424i can support up to eight
(Table 29 on Page 50 and Table 30 on Page 50). Station users can access one, four or eight zones
simultaneously by dialing a brief access code. The zones are composed of customer-supplied
speaker(s) and amplifier(s) which interface with one or two PIOU PCBs. DK14 does not support
zone paging.
Flexible Button Assignment
Each of the flexible buttons on digital and electronic telephones can be assigned for feature or CO
line access, enabling station users access to features and lines with the touch of a button. Digital
telephones are available in 10- and 20-button models.
Flexible Directory Numbers
A “flexible” number of digits can be programmed for station [DNs] in the Strata DK. DK station
[DNs] can have from one to four digits. The maximum available number of unique station [DNs]
([PDNs] plus [PhDNs]) are listed below:
♦ DK14 – up to 20 unique station [DNs] are allowed
♦ DK40i – up to 56 unique station [DNs] are allowed
♦ DK424i – up to 672 unique station [DNs] are allowed
Single-digit [DNs], such as “0”, can be assigned to attendant consoles or attendant telephones.
