NO CID DSP Caller ID Digital Signal Processors (CIDDSP’s) are resourcesin the iDCS 100 Release 2, iDCS 500 Release 2, andOfficeServ 7200 systems required for receiving CID data. Ifthere are no CIDDSP’s available at the time a call comes in,this is the message 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). Notethat ANI does not provide calling party NAME, only the number.The phone systemcan 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 only supports num-ber delivery and, like ANI, a name can be attached to the telephone number of fre-quent callers via the Caller ID translation table. On 5ESS and NI2 PRI circuits bothname and number support is provided on the iDCS 100 Release 2, iDCS 500Release 2, and on the OfficeServ 7200 systems. On a DMS100 circuit only numberservice is provided.SELECTING YOUR CALLER IDDISPLAYYou can decide if you want to see the Caller ID name or Caller ID number in thedisplay.

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 phone system can handle both types of Caller ID; in fact, in the case of num-ber only delivery, the system can be programmed to insert a name for a specifictelephone number. However, even though you are paying to receive Caller IDinformation, there are some circumstances that mean you will not receive this in-formation. The six most common reasons are listed below along with the displayinformation that the system 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 calls canusually be found in the front section of the telephone direc-tory.OUT OF AREA The caller is calling from an area that cannot provide CallerID information (for example, international calls) or he/she iscalling from a type of circuit that cannot provide Caller IDinformation, for example, some outbound WATS lines.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 be de-livered 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.
