System Features
Day/Night Modes
72 Strata DK General Description 6/00
Day/Night Modes
The system has three available ringing modes for routing incoming line calls. The routing
destinations are [DNs], ACD groups, Distributed Hunt groups, Auto Attendant, DISA, and a night
bell. The ringing modes are Day, Day2, and Night.
Each mode can be assigned a distinct ringing destination. The system can be programmed with
either two modes (Day, Night) or three modes (Day, Day 2, Night), which can be changed by any
station programmed with a
1LJKW7UDQVIHU button. A supervisor’s 1LJKW/RFN button can be
provided to prevent false changes in modes. Day/Night call routing applies to all incoming line
types: ANI, DNIS, Caller ID, DISA, Tie, and DID lines.
Delayed Ringing
If an incoming CO, DID or Tie line or internal [DN] call rings a station [DN] and is unanswered,
alternate stations can be programmed to ring 12 or 24 seconds later. The stations that were ringing
initially will continue to ring after the Delayed Ringing begins. This feature is assigned on a line-
by-line and [DN] basis.
It is also possible to direct loop or ground start CO line calls to the Strata DK built-in AA on a
delayed ring basis. In this case, the telephone(s) that initially ring will stop ringing when the AA
answers.
Dialed Number Identification Service (DNIS)
(DK40i, DK424i 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.
♦ 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.
♦ DK424i each support up to 500 DNIS numbers and a maximum of 300 telephone network
numbers. BRCS optional tone receiver PCB is required for DNIS. See “Station Features by
Station Type” on Page 110.
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 (Table 34). The DNIS (called number) digits can be received independently or
simultaneously with ANI “calling number” digits (see “Automatic Number Identification (ANI)”
on Page 68).
