Data Security - Samsung iDCS500 Manual

Data Security

Single line extensions used with modems and facsimile machines can be programmed so that they will
not receive any system-generated tones that would disrupt data transmissions. In addition, these
devices receive DCS C.O. ringing pattern instead of intercom ring pattern. Devices connected to an
SLI card receive a disconnect signal upon termination.
Database Printout
A copy of the customer database can be obtained by using PCMMC. This information 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.
Dialed Number Identification Service (DNIS)
When DNIS service is provided on an incoming trunk the iDCS 500 can route calls based on the
numbers received.
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)
The term Direct Inward Dialing or DID refers to four types of digit steered inbound call handling.
These are DID, Both Way DID, Dialed Number Identification service (DNIS and Direct Dial In (DDI).
The iDCS 500 supports all four types as 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 circuits 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 channel on a digital E1 service terminating on an 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 E&M card or on a channel of a digital E1 circuit on an TEPRI card.
Dialed Number Identification service (DNIS) is a feature of 800 or 900 type numbers 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 terminates on E&M tie lines. These E&M tie line circuits can
terminate on either the E&M card or on a channel of a digital E1 circuit on an 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.
Direct Inward System Access (DISA)
Users can call in on specific DISA lines at any time, input a security code and receive system dial tone.
Users can now place internal calls or if permitted, calls using C.O. lines. The caller must have a tone
dial phone and know his/her DISA security code. DISA lines can be used as both way lines or
incoming only and may be active in day mode, night mode or both. The C.O. lines used for DISA
must have disconnect supervision. The requirement to put in a DISA security code can be disabled if
desired.
