Caller ID Information
The caller ID is a generic name for the service provided by telephone utilities that supply information such as
the telephone number or the name of the calling party to the called subscriber at the start of a call. In call
waiting, the caller ID service supplies information about a second incoming caller to a subscriber already busy
with a phone call. However, note that caller ID on call waiting is not supported by all caller ID-capable
telephone displays.
In typical caller ID systems, the coded calling number information is sent from the central exchange to the
called telephone. This information can be shown on a display of the subscriber telephone set. In this case, the
caller ID information is usually displayed before the subscriber decides to answer the incoming call. If the line
is connected to a computer, caller information can be used to search in databases and additional services can
be offered.
The following basic caller ID features are supported:
 Date and Time
 Calling Line Identity
 Reason for Absence of Calling Line Identity
 Calling Party Name
 Reason for Absence of Calling Party Name
 Visual Indicator (MWI)
Caller ID Generation
There are two methods used for sending caller ID information depending on the application and country-
specific requirements:
 caller ID generation using DTMF signalling
 caller ID generation using Frequency Shift Keying (FSK)
Both methods can be used on different lines at the same time.
DTMF Signalling
The data transmission using DTMF signalling is performed during or before ringing depending on the country
settings or line configuration. The Mediatrix 4100 provides the calling line identity according to the following
standards:
 Europe: ETSI 300 659-1 January 2001 (Annex B) : Access and Terminals (AT); Analogue
access to the Public Switched Telephone Network (PSTN); Subscriber line protocol over the
local loop for display (and related) services; Part 1: On-hook data transmission.
 Denmark: TDK-TS 900 301-1 January 2003: Public Switched Telephone Network (PSTN)
