Dialed Number Identification service (DNIS) is a feature of 800 or 900 type numbers that allows the numberdialed by the caller to be identified in the telephone system by means of a sequence of DTMF digits (usuallyfour). This service terminates on E&M tie lines. These E&M tie line circuits can terminate on the digital T1 cir-cuit on an iDCS TEPRI/TEPRIa card.Direct Dial In (DDI). This is the name given to the above three services when they are provided over an ISDNPRI circuit.The OfficeServ 500 has an option to select which MOH source is played to callers to a specific DID number.DID Call LimitsThis option defines the maximum number of simultaneous calls that the system will accept for each DIDnumber. Any call attempts after the Maximum Call (MC) count has been reached will be rejected and busytone returned.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. Userscan now place internal calls or if permitted, calls using C.O. lines. The caller must have a tone dial phone andknow his/her DISA security code if DISA security codes/passcodes are turned on. DISA lines can be used asboth way lines or incoming only and may be allowed or disallowed for any of the 6 ring plan time periods.The C.O. lines used for DISA must have disconnect supervision.The requirement to put in a DISA security codecan be disabled if desired.DIRECT TRUNK SELECTIONEach station can be allowed access to or denied access from a trunk or trunk group by access code when LCRis activated. When restricted, the station user must use a trunk key or a route key.DIRECTORY NAMESEach station, station group and C.O. line may be assigned a directory name (maximum 11 characters). In addi-tion, each personal speed dial number, system speed dial number and entry in the DID translation table maybe assigned a name (maximum 11 characters). These names are displayed during calls with these ports andin the case of station and speed dial names, can be used to originate calls. See the Dial by Name feature(Station Features).DISA SECURITYTelephone fraud and long distance theft are a serious concern. The OfficeServ 500 provides a strong DISAsecurity system. If an incorrect DISA passcode is entered repeatedly (as is the case with “hackers”), the DISAsystem can be automatically disabled temporarily. Both the number of incorrect passcode attempts and thetime that DISA is disabled are programmable. In addition, all failed attempts to access DISA print on SMDR (ifprovided) with a “DE” DISA error flag.DISTINCTIVE RINGINGThe OfficeServ 500 provides distinctive ringing at a station based on selected parameters.• Outside calls have a single ring repeated, while intercom calls have a double ring repeated.• Any trunk or station can be programmed to ring a specific digital keyset with a predefined ring tone (1-8) or an analog station with a predefined cadence (1-5) selection.• Digital keysets and analog stations may receive distinctive ringing based on the Caller ID numberreceived or the DID number dialed.4.15
