4- AND 8-LINE CALLER ID

5.3 Message Format

The 72-character-long Caller ID records sent by the Caller ID unit will be
automatically displayed by the attached terminal or printed by the attached line
printer. These records' populated fields (shown in Figure 5-1 on the previous
page) are all right-justified and (except for the Name field) followed by a filler
containing five space characters. Except for the Line field, all of the information in
these fields is included in the Caller ID data provided by the local phone company.
Here's more information about them:
• Line (2 characters): Tells you which line the call was received on. This number
is generated internally by the Caller ID system. In a system with all 4-Line units,
ports "01 through "04" are ports 1 through 4 respectively on unit #1; ports "05"
through "08" are ports 1 through 4 on unit #2; and so on. In a system with all
8-Line units, ports "01 through "08" are ports 1 through 8 respectively on
unit #1; ports "09" through "16" are ports 1 through 8 on unit #2; and so on.
• Date (5 characters): The month and date (not the year) when the call was
received. (For DTE-programming purposes, be aware that the Caller ID unit
sometimes fills this field, the Time field that follows, and the filler between
them with right-justified text such as "MESSAGE WAITING," "MESSAGE
RETRIEVED," and "INVALID DATA.")
• Time (8 characters): The time of day (in [hour]:[minute] AM/PM format)
when the call was received.
• Phone Number (14 characters including dashes): The first 11 digits of the
phone number of the calling party. When you are called by someone whose
phone number is not available, is blocked, etc., you will receive a
corresponding word or phrase in this field (such as "OUT OF AREA" or
"PRIVATE"), but the exact text will vary from one phone company to another.
• Long Distance Indicator (1 character): If the call originated from another area
code, an "L" might appear in a column between the phone number and the
name to indicate that it's a long-distance call. This tag is included in the Caller
ID data provided by the local phone company.
• Name (15 characters): The first 15 characters (upper/lowercase is preserved)
of the name of the calling party will appear in this field if "Multiple Message"
format and "Call Name Delivery" service are available in your area, and if the
local phone company sends the name information. Otherwise, this field will be
blank.
The last two characters of each record are a carriage return (0D hex) and a line
feed (0A hex) intended to move the DTE to the next line.
