NO CID DSP Caller ID Digital Signal Processors (CIDDSP’s) areresources in the iDCS system required for receiving CIDdata. If there are no CIDDSP’s available at the time acall comes in, this is the message you will see on yourdisplay.NOTE: The Caller ID features require optional software and/or hardware.Please see your service and installation company for details.WHAT IS ANI?ANI (Automatic Number Identification) is a feature offered by some tele-phone service providers that provides the calling party’s telephone number.This service is only available on E&M Tie Lines on a T1, digital trunk. ANI issimilar to Caller Identification (CID) but the format and information of thecalling person is different. CID uses FSK signalling and ANI uses DTMF sig-nalling. Usually, with ANI, a calling party’s identity is the Listed DirectoryNumber (LDN) unless a separate bill-to-number has been specified, (inwhich case the bill-to-number will be sent). Note that ANI does not providecalling party NAME, only the number. The phone system can provide callingnumber to name translation table.WHAT IS CLI?On ISDN circuits, calling party information is called CLI and is supported onboth BRI and PRI type circuits on the iDCS. On BRI circuits the iDCS onlysupports number delivery and, like ANI, a name can be attached to the tele-phone number of frequent callers via the Caller ID translation table. On5ESS and NI2 PRI circuits both name and number support is provided onthe iDCS system. On a DMS100 circuit only number service is provided.SELECTING YOUR CALLER IDDISPLAYYou can decide if you want to see the Caller ID name or Caller ID number inthe display.

There are two types of Caller ID; the first delivers the callingparty’s telephone number only and the second (sometimes referred to as“Deluxe” Caller ID) delivers both the calling party’s telephone number andname as listed in the telephone directory.The phone system can handle both types of Caller ID; in fact, in the case ofnumber only delivery, the system can be programmed to insert a name fora specific telephone number. However, even though you are paying toreceive Caller ID information, there are some circumstances that mean youwill not receive this information. The six most common reasons are listedbelow along with the display information that the system will provide.PRIVATE The caller does not wish his/her name or number to berevealed to you. This type of call can be stopped at thetelephone company by dialing an access code on youroutside lines. This will redirect these PRIVATE calls toan announcement that states that you do not wish to re-ceive calls that have had Caller ID blocked. The code toblock these calls can usually be found in the front sec-tion of the telephone directory.OUT OF AREA The caller is calling from an area that cannot provideCaller ID information (for example, international calls) orhe/she is calling from a type of circuit that cannot pro-vide Caller ID information, for example, some outboundWATS lines.PAYPHONE The caller is calling from a coin-operated telephone.The telephone company will send this information asthere are no directory listings for pay phones. The num-ber will be delivered as usual.INVALID CID INFO This is a message that will be displayed when CID infor-mation is sent on the line but was somehow corrupted.NO CID RECEIVED This is a message that will be displayed when there wasno CID information sent on the line.
