Dialed Number Identification Service (DNIS)

DNIS identifies the called number and displays it on the LCDs of ringing telephones. The DK424
compares the received digits (DNIS tag) to a program table that determines how to route the call
and what display to provide. A 16-character alpha/numeric identifier is displayed on the ringing
telephone's LCD or Attendant Console display.
DNIS digits can also be sent to an application computer. DNIS
names are stored within the Strata DK as defined by the user and
programmed into Strata DK system programming. The names
display on direct, incoming, transferred, and call forwarded
calls. This enables calls to be answered appropriately by type of
call. A DNIS display is shown below:
Figure 3 shows a sample overview of the call flow provided by the Strata DK DNIS capability.
DNIS is supported on digital T1 or analog DID and Tie lines. DNIS is typically used with "1-800"
type of calls using long distance carriers over T1, but can also be provided over analog DID and
Tie line circuits.
It is important to note that the Strata DK DNIS feature can treat all incoming local DID and Tie
line calls the same. It can treat them as incoming DNIS long distance 1-800 calls for the purpose of
routing these calls through the DNIS tables in the Strata DK. This is what makes DNIS such a
flexible feature.
DNIS enables multiple numbers to ring into the same line or line group, providing optimum trunk
usage as well as helpful called number/name identification information. This provides much more
efficient usage of lines than the traditional usage of 800 numbers. Traditionally, each 800 number
was assigned to its own line group, often resulting in a large number of under-used lines. The
Strata DK DNIS capability solves this problem by using each DNIS line on an as-needed basis for
different 800 number calls.
DNIS data is routed to DNs that can have multiple appearances, Distributed Hunt groups, ACD
groups (DK424 only), and external network numbers through external call routing. DNIS digits
can be received independently or simultaneously with ANI digits.
Each DNIS number can have its own voice mail ID code and can be routed to different
destinations during Day/Day2/Night mode.
The DK424 supports 500, 350, 200 DNIS numbers and 300, 200, 100 telephone network numbers
for the RCTUE/F, RCTUC/D, RCTUBA/BB, RCTUA, respectively. The DK40i supports 200.
