Dialed Number Identification Service (DNIS) (DK40i and DK424 only)

This feature enables incoming DNIS (called party) telephone numbers to display on the LCDs of
ringing telephones. DNIS is provided on analog, and/or digital (T1, ISDN PRI/BRI), DID and Tie
lines. An optional DTMF tone receiver PCB is required for DNIS.
Normally, DNIS is associated with "1-800" type calls offered by various long distance carriers;
however, the Strata DK can provide DNIS information over DID and Tie line circuits.
Traditionally, each 800-number is assigned to its own line group, often resulting in a large number
of under-used lines. DNIS allows multiple numbers to ring into the same line or line group, which
provides a more efficient use of 800-numbers. Each DNIS line is used on an as-needed basis for
different 800-number calls.
DK14 does not support DNIS.
DK40i supports up to 200 DNIS numbers and a maximum of 100 telephone network numbers.
The K5RCU (DK40i) optional tone receiver PCB is required for DNIS. Each DNIS, DID or
Tie line reduces the station capacity by one.
DK424 supports up to 500 DNIS numbers and a maximum of 300 telephone network
numbers. RRCS optional tone receiver PCB is required for DNIS. See

Systems, Release 4.0.
The DNIS numbers are correlated in the system database with assigned DNIS names. DNIS names
(up to 16 alphanumeric characters) display on direct incoming, transferred, and Call Forward calls.
This allows incoming calls to be identified and answered appropriately.
DNIS numbers can be assigned to ring unique destinations in the Day, Day2, and Night Ring
modes (see
simultaneously with ANI "calling number" digits
on Page
Priority of ANI or DNIS is set for each line in system programming. DNIS digits can also be sent
to a PC. See
External Telephone Network Numbers
All DNIS/DID/Tie numbers that ring into the Strata DK can be routed externally to any outside
telephone number. Depending on the application, the caller DNIS name may be passed to the
destination Strata DK when routed over the telephone network.
Voice Mail
If assigned in the system database, incoming calls for each unique DNIS/DID/Tie number can be
directly routed or Call Forwarded to a designated voice mailbox. This allows callers of each DNIS/
DID/Tie number to receive immediate personal custom greetings.
Note This feature is available on in-band integration only. It is not available using SMDI.

Direct Inward Dialing (DID) Lines (DK40i and DK424 only)

Based on the final digits of a dialed telephone number, DID enables incoming calls over a single
line to directly ring one or a number of stations which share a common [DN]. DID numbers can be
assigned to ring a number of destinations (see
DID is provided by analog or digital (T1, ISDN PRI/BRI) lines. The TDDU and RDDU analog
PCBs support DID. For the DK424 only, the digital T1/DS-1 (RDTU2) or ISDN PRI (RPTU)
PCBs support DID.
