NO CID DSP Caller ID Digital Signal Processors (CIDDSP’s) are resourcesin the iDCS required for receiving CID data. If there are noCIDDSP’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 iDCS 100 Release 2, iDCS 500 Release 2, and the OfficeServ7200 systems where to route the call. Note that ANI does not provide calling partyNAME, only the number. The iDCS 100 Release 2, iDCS 500 Release 2, and theOfficeServ 7200 systems can provide calling number to name translation table.WHAT IS CLI?On ISDN circuits, calling party information is called CLI and is supported on bothBRI and PRI type circuits on the iDCS. On BRI circuits the iDCS 100 R2, iDCS 500 R2,and OfficeServ 7200 systems only support number delivery and, like ANI, a namecan be attached to the telephone number of frequent callers via the Caller IDtranslation table. On 5ESS and NI2 PRI circuits both name and number support isprovided 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.

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 iDCS 100 Releae 2, iDCS 500 Release 2, and OfficeServ 7200 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 iDCS 100 Release 2, iDCS 500 Release 2, and theOfficeServ 7200 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.NO CID RECEIVED This is a message that will be displayed when there was noCID information sent on the line.52
