System Features
Direct Inward Dialing (DID) Lines (DK40i, DK424i only)
Strata DK General Description 6/00 73
Priority of ANI or DNIS is set for each line in system programming. DNIS digits can also be sent
to a PC. See “Computer Telephony Integration (CTI)” on Page 70.
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, DK424i 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 Table 34). DK14 does not support DID.
DID is provided by analog or digital (T1, ISDN PRI/BRI) lines. The TDDU and RDDU analog
PCBs support DID. For the DK424i only, the digital T1/DS-1 (RDTU2) or ISDN PRI (RPTU)
PCBs support DID.
Each DID number can be assigned a Name to display on an LCD telephone that rings when the
DID number is called. Each DID line has a single office code and a block of extension numbers
(the final digits) that can be individually assigned in system programming to ring stations.
DID lines can directly access the remote maintenance modem and can optionally provide
automatic Camp-on-busy when callers dial a busy [DN] on incoming DID calls. This feature
provides a camp-on tone and distinctive LED flash at the busy station.
♦ DK40i and DK424i – DID lines do not affect station port capacity.
An optional tone receiver PCB (K5RCU or BRCS) is required for DID line DTMF operation.
Direct Inward System Access (DISA)
Outside callers using a DTMF-capable telephone can dial internal stations or outgoing lines
directly, without going through a receptionist or operator. DISA security codes and/or a verified
account codes, each up to 15 digits, can be assigned to prevent undesired access to lines.
DISA is available to any quantity of ground or loop start lines (not Tie or DID), either directly or
through the Strata DK built-in AA. It enables privileged users to take advantage of the benefits of
the Strata DK even when they are not on the premises. An optional tone receiver PCB (QRCU3,
K5RCU or BRCS) is required for DISA.
DISA can be accessed by calling into the DK built-in AA. To prevent users from calling into the
Auto Attendant and accessing an outgoing line with DISA to make unauthorized external calls, be
sure to use the DISA security code.
