MERLIN Identifier Control Unit provides Caller ID functions,
administrative functions, and the MERLIN Identifier database. For
each incoming call, the MERLIN Identifier system sends the
following information to the MERLIN Identifier Displays: the last
two digits of the line number on which the call was received, the
time and date of the call as recorded at the Central Office, and if
the caller's exchange provides Caller ID service, the caller's
telephone number as well.
