NO CID DSP
Caller ID Digital Signal Processors (CIDDSP’s) are
resources in the iDCS 500 required for receiving CID
data. If there 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 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 is
similar to Caller Identification (CID) but the format and information of the
calling person is different. CID uses FSK signalling and ANI uses DTMF sig-
nalling. Usually, with ANI, a calling 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). Note that ANI does not provide
calling party NAME, only the number. The phone system can provide calling
number to name translation table.
WHAT IS CLI?
On ISDN circuits, calling party information is called CLI and is supported on
both BRI and PRI type circuits on the iDCS. On BRI circuits the iDCS only
supports number delivery and, like ANI, a name can be attached to the tele-
phone number of frequent callers via the Caller ID translation table. On
5ESS and NI2 PRI circuits both name and number support is provided on
the iDCS system. On a DMS100 circuit only number service is provided.

CALLER ID
WHAT IS CALLER ID?
Caller ID is the name given to the telephone company-provided feature that
delivers the telephone number and sometimes the name of the person call-
ing your phone. There are two types of Caller ID; the first delivers the calling
party’s telephone 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 telephone directory.
The phone system can handle both types of Caller ID; in fact, in the case of
number only delivery, the system can be programmed to insert a name for
a specific telephone number. However, even though you are paying to
receive Caller ID information, there are some circumstances that mean you
will not receive this information. The six most common reasons are listed
below along with the display information that the system will provide.
PRIVATE
The caller does not wish his/her name or number to be
revealed to you. This type of call can be stopped at the
telephone company by dialing an access code on your
outside lines. This will redirect these PRIVATE calls to
an announcement that states that you do not wish to re-
ceive calls that have had Caller ID blocked. The code to
block 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 provide
Caller ID information (for example, international calls) or
he/she is calling from a type of circuit that cannot pro-
vide Caller ID information, for example, some outbound
WATS lines.
PAYPHONE
The caller is calling from a coin-operated telephone.
The telephone company will send this information as
there 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 was
no CID information sent on the line.
