Chapter - ICLID / Caller ID
Introduction
Description
Incoming Calling Line IDentification (ICLID), or Caller ID, is a service provided from the
telephone company. Usually this service provides the number and name (not available in
some cases) of the calling party for identification prior to answering the call. Calling party
number and name are delivered in between this first and second ring using FSK (Frequency
Shift Key) format.
For this feature to operate properly, it must be activated from the Central Office so the
numbers or name, if available, of the calling party are delivered over the individual tip and
ring of the CO lines during the first silent interval between ringing.
The following illustration depicts the configuration presumed for the implementation of the
ICLID feature for the system. The phones are presumed to be in an ACD or UCD group in
order to allow proper operation with the system.
