NO CID RECEIVED This is a message that will be displayed when there was noCID information sent on the line.NO CID DSP Caller ID Digital Signal Processors (CIDDSP’s) are resourcesin the system required for receiving CID data. If there areno CIDDSP’s available at the time a call comes in, this is themessage you will see on your display.NOTE:The Caller ID features require optional software and/or hardware. Please seeyour service and installation company for details.WHAT IS ANI?ANI (Automatic Number Identification) is a feature offered by some telephoneservice providers that provides the calling party’s telephone number. This serviceis only available on E&M Tie Lines on a T1, digital trunk. ANI is similar to CallerIdentification (CID) but the format and information of the calling person is differ-ent. CID uses FSK signalling and ANI uses DTMF signalling. Usually, with ANI, a call-ing party’s identity is the Listed Directory Number (LDN) unless a separate bill-to-number has been specified, (in which case the bill-to-number will be sent). Alongwith the ANI digits you also receive DNIS digits with a separator digit. The DNISdigits are used to tell the OfficeServ 100, OfficeServ 500, and the OfficeServ 7000Series systems where to route the call. Note that ANI does not provide callingparty NAME, only the number. The OfficeServ 100, OfficeServ 500, and theOfficeServ 7000 Series systems can provide calling number to name translationtable.WHAT IS CLI?On ISDN circuits, calling party information is called CLI and is supported on bothBRI and PRI type circuits. On BRI circuits the OfficeServ 100, OfficeServ 500, andOfficeServ 7000 Series systems only support number delivery and, like ANI, aname can be attached to the telephone number of frequent callers via the CallerID translation table. On 5ESS and NI2 PRI circuits both name and number supportis provided on the system. On a DMS100 circuit only number service is provided.SELECTING YOUR CALLER IDDISPLAYYou can decide if you want to see the CID number in the display. Regardless ofwhich one is selected, you can press the NDD key to view the other pieces of CIDinformation. To select the type of Caller ID information you wish to view first:• With the handset on-hook, press TRSF and then dial 119.53WHAT IS CALLER ID?Caller ID is the name given to the telephone company-provided feature that de-livers the telephone number and sometimes the name of the person calling yourphone. There are two types of Caller ID; the first delivers the calling party’s tele-phone number only and the second (sometimes referred to as “Deluxe” Caller ID)delivers both the calling party’s telephone number and name as listed in the tele-phone directory.The OfficeServ 100, OfficeServ 500, and OfficeServ 7000 Series systems can han-dle both types of Caller ID; in fact, in the case of number only delivery, the systemcan be programmed to insert a name for a specific telephone number (up to amaximum of 1500 numbers). However, even though you are paying to receiveCaller ID information, there are some circumstances that mean you will notreceive this information.The six most common reasons are listed below along withthe display information that the OfficeServ 100, OfficeServ 500, and the OfficeServ7000 Series systems will provide.PRIVATE The caller does not wish his/her name or number to be re-vealed to you. This type of call can be stopped at the tele-phone company by dialing an access code on your outsidelines. This will redirect these PRIVATE calls to an announce-ment that states that you do not wish to receive calls thathave had Caller ID blocked. The code to block these callscan usually be found in the front section of the telephonedirectory.OUT OF AREA The caller is calling from an area that cannot provide Call-er ID information (for example, international calls) orhe/she is calling from a type of circuit that cannot provideCaller ID information, for example, some outbound WATSlines.PAYPHONE The caller is calling from a coin-operated telephone. Thetelephone company will send this information as there areno directory listings for pay phones. The number will bedelivered as usual.INVALID CID INFO This is a message that will be displayed when CID informa-tion is sent on the line but was somehow corrupted.52
