DATABASE PRINTOUT
A copy of the customer database can be obtained by using PCMMC. This informa-
tion can be directed to a printer or the PC screen and may be done either on-site or
remotely. A complete database or specific data blocks may be obtained.
DAYLIGHT SAVING TIME-AUTOMATIC
The system has a table that can be programmed with the daylight savings change
dates for up to 10 years. At 2:00 am on these dates the system will automatically
adjust the system clock to match daylight savings time. If no dates are programmed
the clock will not change.
DIALED NUMBER IDENTIFICATION SERVICE (DNIS)
When DNIS service is provided on an incoming E&M trunk the iDCS 500 can route
calls based on the numbers received. (See DID)
DIRECT IN LINES
Outside lines may be programmed to bypass the operator(s) and ring directly at
any station or group of stations.
DIRECT INWARD DIALING (DID) T1/COPPER
The term Direct Inward Dialing refers to types of digit steered inbound call han-
dling. These are DID, Both Way DID, Dialed Number Identification service (DNIS)
and Direct Dial In (DDI). The iDCS 500 supports the types described below.
DID is an inbound only service where multiple telephone numbers are assigned,
usually in blocks of twenty, to a single circuit or small group of circuits. These cir-
cuits can be single pair analog circuits that will terminate on a DID card. The iDCS
500 DID card supports up to four circuits. In addition the DID circuit can be a chan-
nel on a digital T1 service terminating on an iDCS 500 TEPRI card.
Both way DID is a service that combines DID service with normal outbound local
telephone service. This service is provided over E&M tie line circuits. These E&M
tie line circuits can terminate on either the iDCS E&M card or on a channel of a
digital T1 circuit on an iDCS TEPRI card.
Dialed Number Identification service (DNIS) is a feature of 800 or 900 type num-
bers that allows the number dialed by the caller to be identified in the telephone
system by means of a sequence of DTMF digits (usually four). This service termi-
nates on E&M tie lines. These E&M tie line circuits can terminate on either the iDCS
E&M card or on a channel of a digital T1 circuit on an iDCS TEPRI card.
Direct Dial In (DDI). This is the name given to the above three services when they
are provided over an ISDN PRI circuit.
The L version of the iDCS 500 has an option to select which MOH source is played
to callers to a specific DID number.
