CHAPTER 2: Introduction
2. Introduction
2.1 Overview
The 4- and 8-Line Caller ID units (product codes TE120A and TE121A
respectively) receive Caller ID (identification) data from the telephone company
and send the data, in ASCII RS-232C format, to a printer, terminal, computer, or
other DTE (data terminal equipment). As an interface, the Caller ID unit only
receives, converts, and then resends the the Caller ID information to a DTE device
(not included). Any printing or displaying of the data is done by the DTE.
The Caller ID unit is compatible with most key systems and PBXes, and is also
compatible with most of the current C.O.-based message-waiting services. This
device is single- and multiple-message compatible. Caller ID services are currently
being offered by many telephone companies as a subscribed service (check for
service availability).
The Caller ID units have one or two 8-position DIP switches on their front panels
(shown in Figures 2-1 and 2-2 on the next page). These switches control the data
rate, data bits, parity, voltage, and line or port specifications for configuring the
unit to work with the DTE device.
The telephone-line ports are located on the rear panels of the Caller ID units
(also shown in Figures 2-1 and 2-2 on the next page). You’ll use regular modular
phone cable to attach these RJ-14C (TE120A) or RJ-11C (TE121A) input jacks to
the incoming telephone lines from the central office. You’ll be using line splitters
or cross-connects to attach the Caller ID units “in parallel” with the telephone
devices associated with those lines (see Chapter 4).
The Caller ID unit’s power-supply connector is also located on its rear panel.
The power supply is an external AC-power adapter requiring a common AC outlet.
On the rear panel there are also two connectors, RS-232 IN and RS-232 OUT,
which you can use to daisychain (interconnect) as many as eight Caller ID units in
order to monitor up to 32 or 64 lines or ports with a single RS-232 connection to a
DTE. (32 will be the maximum number of lines if you use any 4-port units; 64 will
be the maximum if you use only 8-port units.)

CHAPTER 2: Introduction
2.2 How the Caller ID Units Work
The Caller ID units receive calls on any of their modular phone-line ports, which
you’ll connect directly to the incoming central-office telephone lines in parallel
with the telephone, key system, or PBX. After detecting the Caller ID data from the
local telephone company, the Caller ID unit stamps this information with the port
number, converts it into ASCII, and transmits it from its RS-232 OUT port to an
attached PC, printer, or other RS-232 DTE. (The Caller ID unit will only indicate
that data has been received if a DTE is connected to the RS-232 OUT port. It will
light its “DATA” LED to indicate that it’s sending data through its RS-232 OUT
port.) The flow of the data in systems with a single Caller ID unit is shown in
Figures 2-3 and 2-4 on the next two pages; the data flow in systems with multiple
daisychained Caller ID units is shown in Figures 2-5 and 2-6 on the pages that
follow.
What happens to the data after the Caller ID unit transmits it to the DTE is up to
you. You could buy or write a software program to process it (this is often done in
conjunction with a database). But any serial printer, terminal, or PC running a
terminal emulator should be able to accept the data without requiring extra
hardware or software if all you need to do is monitor the data as it’s printed or
appears on screen.

2.3 Connectors and Pinouts
There are several connectors on the Caller ID units. Each 4-Line unit (TE120A)
has two dual-line RJ-14C female telephone-line ports and a barrel-type power inlet.
Each 8-Line unit has eight single-line RJ-11C female telephone-line ports and a
5-pin DIN female power inlet. The RJ-14C and RJ-11C pinouts look like this:
Pin RJ-14C (TE120A) Signal RJ-11C (TE121A) Signal
1, 6 [No connection] [No connection]
2 2nd line (2 or 4) tip [No connection]
3 1st line (1 or 3) tip Tip
4 1st line (1 or 3) ring Ring
5 2nd line (2 or 4) ring [No connection]
Both 4- and 8-Line units have two RS-232 ports whose data rate, parity, data bits,
and flow control are all user-selectable (see Section 3.2). The RS-232 OUT port is a
DB9 female connector pinned as an RS-232 DCE port. (This means that it actually
transmits data on its Receive Data lead, as a modem would.) It’s designed to be
connected to printers, terminals, PCs running terminal emulators, and other
DTEs. (In daisychained applications, it can be connected to the RS-232 IN port of
the next Caller ID unit in the chain.) The RS-232 OUT port is pinned this way:
Pin Signal Direction
1 Carrier Detect (CD) Out (to other device)
2 Receive Data (RD) Out (to other device)
5 Signal Ground (SGND) N/A
6 Data Set Ready (DSR) Out (to other device)
7 Request to Send (RTS) In (from other device)
8 Clear to Send (CTS) Out (to other device)
9 Busy Out (to other Caller ID unit)
NOTES
Pin 7, RTS, must be pulled active (high) in order for the Caller ID unit to
turn on its DATA LED when it receives Caller ID information from a
telephone line.
Pin 9, Busy, is a proprietary signal used primarily for communication
between daisychained Caller ID units, although it can be connected to
Pin 22, Ring Indicator (RI), on a DTE with a DB25 serial port, as shown in
Table 4-1 at the end of Chapter 4.
17
CHAPTER 2: Introduction
The RS-232 IN port is a DB9 male connector pinned as an RS-232 DTE port. It’s
only used when multiple Caller ID units are daisychained together; it receives
information from units farther along in the chain. The RS-232 IN port is pinned
this way (see the Note on the previous page about the Busy signal on Pin 9):
Pin Signal Direction
2 Receive Data (RD) In (from other Caller ID unit)
5 Signal Ground (SGND) N/A
7 Request to Send (RTS) Out (to other Caller ID unit)
8 Clear to Send (CTS) In (from other Caller ID unit)
9 Busy In (from other Caller ID unit)

4- AND 8-LINE CALLER ID
3. Configuration
You’ll configure your Caller ID units for your application using their frontmounted 8-position configuration DIP switches. Both models have a switch labeled
S2 that controls RS-232 characteristics and unit number. The 8-Line model has an
additional switch labeled S1 for signal handling.
3.1 DIP Switch S1 (TE121A Only)
DIP switch S1 controls the voltage and behavior of three of the pins/signals on the
RS-232 OUT port (see Section 2.3) of the 8-Line Caller ID (TE121A
), so that it will
be compatible with your other RS-232 devices. (All of the
possible settings of S1’s
switch positions that aren’t listed below are invalid—do not use unlisted settings,
because they could disable or damage attached equipment.)
Positions 1 and 2 govern how Pin 1, Carrier Detect (CD), is handled:
• 1 OFF, 2 OFF: Pin 1 output is disabled (factory-default setting).
• 1 ON, 2 OFF: Causes continuous +12 VDC output on Pin 1.
• 1 OFF, 2 ON: Causes continuous –12 VDC output on Pin 1.
Positions 3, 4, and 5 govern how Pin 6, Data Set Ready (DSR), is handled:
• 3 OFF, 4 OFF, 5 OFF: Pin 6 output is disabled (factory-default setting).
• 3 ON, 4 OFF, 5 OFF: Causes continuous +12 VDC output on Pin 6.
• 3 OFF, 4 ON, 5 OFF: Causes Pin 6 (DSR) output to follow Pin 8 (CTS) output.
• 3 OFF, 4 OFF, 5 ON: Causes continuous –12 VDC output on Pin 6.
Positions 6, 7, and 8 govern how Pin 9, the proprietary Busy signal, is handled:
• 6 OFF, 7 OFF, 8 OFF: Pin 9 output is disabled (factory-default setting).
• 6 ON, 7 OFF, 8 OFF: Causes continuous +12 VDC output on Pin 9.
• 6 OFF, 7 ON, 8 OFF: Causes Pin 9 output to follow Pin 9 input from the
RS-232 IN port.
• 6 OFF, 7 OFF, 8 ON: Causes continuous –12 VDC output on Pin 9.
19
CHAPTER 3: Configuration
3.2 DIP Switch S2
DIP switch S2 controls both the unit number (if you’ll be daisychaining Caller ID
units) and the serial communication characteristics of the RS-232 OUT and RS-232
IN ports (see Section 2.3) and the unit number (if you will be daisychaining Caller
ID units).
(All of the
possible settings of S2’s switch positions that aren’t listed
below are invalid—do not use unlisted settings, because they could disable or
damage attached equipment.)
Use positions 1 and 2 to set the data rate of the RS-232 OUT port:
• 1 OFF, 2 OFF: 1200 bps.
• 1 ON, 2 OFF: 2400 bps.
• 1 OFF, 2 ON: 4800 bps.
• 1 ON, 2 ON: 9600 bps (factory-default setting).
Use position 3 to set the data bits of the RS-232 OUT port:
• 3 OFF: 7 data bits.
• 3 ON: 8 data bits (factory-default setting).
Use positions 4 and 5 to set the parity of the RS-232 OUT port:
• 4 OFF, 5 OFF: No parity (factory-default setting).
• 4 ON, 5 OFF: Odd parity.
• 4 OFF, 5 ON or 4 ON, 5 ON: Even parity.
Use positions 6, 7, and 8 to set the unit number: “1” for a single unit or “1,” “2,”
etc., for daisychained units successively closer to the DTE. For example, if you have
three 4-Line units in a daisychain, you must set the one farthest from the DTE as
unit #1, the one in the middle as unit #2, and the one attached to the DTE as #3.
(However, if you’ll have 4-Line and 8-Line units in the same daisychain, see the
Note at the start of Chapter 4.) The possible settings are:
• 6 OFF, 7 OFF, 8 OFF: Unit is #1 (factory-default setting).
• 6 ON, 7 OFF, 8 OFF: Unit is #2.
• 6 OFF, 7 ON, 8 OFF: Unit is #3.
.• 6 ON, 7 ON, 8 OFF: Unit is #4.
• 6 OFF, 7 OFF, 8 ON: Unit is #5.
• 6 ON, 7 OFF, 8 ON: Unit is #6.
• 6 OFF, 7 ON 8 ON: Unit is #7.
• 6 ON, 7 ON, 8 ON: Unit is #8

4- AND 8-LINE CALLER ID
4. Installation
To install a system of one or more 4- or 8-Line Caller ID units after you’ve
configured them (see Chapter 3), take these steps, referring to the appropriate
illustrations among Figures 2-3 through 2-6 in Section 2.2:
NOTE
If you want to install a daisychain that includes both 4-Line and 8-Line
units:
1. Such a daisychain supports only 32 lines. If you’ll need to monitor
more lines than that, you’ll need to chain 8-Line units only.
2. All of the 4-Line units must be installed “ahead” of the 8-Line
units. That is, in the sequence of the daisychain, all of the 4-Line units
must be closer to the DTE than any of the 8-Line units.
3. Such mixed daisychains need to be assigned unit numbers (see
Section 3.2) as if the 8-Line units take up two “slots.” For example, if you
were chaining three 8-Line units with two 4-Line units, you’d place one
8-Line unit at the end of the chain and number it “1”; then you’d place
the two other 8-Line units in sequence and number them “3” and “5”;
then you’d place one of the two 4-Line units and number it “6”; and
you’d place the second 4-Line unit at the head of the chain, attached to
the DTE, and number it “7.”
1. Attach line splitters or cross-connects to your site’s phone-line jacks so that
you can send the incoming phone signals to both your telephones and the
Caller ID system. If it’s not possible to plug cross-connects directly into your
site’s phone jacks, you’ll need to use the standalone type of cross-connects
and run standard phone cables from the phone jacks to them.
2. Run standard phone cable from one output of the line splitters or crossconnects to your telephones.
3. Place your Caller ID units close to AC-power outlets. The first unit must be
within 50 ft. (15.2 m) of the DTE that will be receiving the Caller ID
information; if you’re daisychaining, each successive unit needs to be within
50 ft. (15.2 m) of the one before.
4-Line units: A 4-Line unit can be mounted on a wall by hanging it from a
pair of bolts or screws secured into a wall stud. If you want to do this, you
might want to photocopy the mounting template in the Appendix and use it
as a guideline for how much wall area you’ll need and where you’ll need to
position the bolts/screws.
21
CHAPTER 4: Installation
4A. 4-Line units: 4-Line Caller ID units each have two RJ-14C two-line phone-input
connectors; they’re designed to be directly connected to two-line phone jacks.
If your site has standard single-line jacks, and you need to attach three or four
lines to any given 4-Line unit, you’ll need to consolidate the extra lines by
running the included two-to-one condenser cables from the other output of
the cross-connects to the Caller ID’s phone-input connectors. (If you ever
need a replacement for one of these cables, please call Black Box for
technical support.)
If your site does have two-line phone jacks, you can run standard phone
cables instead.
4B. 8-Line units: 8-Line Caller ID units each have eight RJ-11C single-line phone-
input connectors; they’re designed to be directly connected to standard
single-line phone jacks. If your site has single-line jacks, run standard phone
cables from the other output of the cross-connects to the Caller ID’s phoneinput connectors. Only one of these cables is included, for initial testing
purposes; additional cables are available as product code EL04MS-MM.
If your site has two-line phone jacks, you’ll need to use line splitters (not
included) to put the lines on separate connectors.
5. Run an RS-232 cable (not included) from the DB9 female RS-232 OUT port
of your single Caller ID unit or the first (highest-numbered) unit in your
daisychain to an RS-232 serial port on the DTE that will be receiving the
Caller ID information. If the DTE is a PC running terminal emulation, and
you’re connecting the Caller ID unit to one of its DB9 male serial ports, you’ll
need a straight-through-pinned (Pin 1 to 1, 2 to 2, etc) DB9 male-to-female
cable (not included) such as product code EDN12H-MF. If you’re connecting
the Caller ID unit to an actual terminal, or to one of a PC’s DB25 serial ports,
you’ll need a DB9 male to DB25 female cable pinned as shown in Table 4-1
on the next page. If for whatever reason you want to connect the Caller ID
unit to a DCE, please call Black Box for technical support.
CAUTION!
To prevent noise problems, the Caller ID unit is grounded through this
serial cable and the DTE, not through its own power supply; the DTE
must, in turn, be grounded to your site’s grounding system through its
power cord or power supply. The grounding obtained through a
standard 3-prong AC-power outlet and power cord should be sufficient,
providing the AC outlet has been properly installed. Failure to properly
ground the DTE might cause the DTE and/or the Caller ID unit to
malfunction or be damaged, and also creates an electrical and fire
hazard. Do not use AC isolation plugs.

6. If you’re daisychaining Caller ID units: Run a straight-though-pinned (Pin 1 to 1,
2 to 2, etc) DB9 male-to-female cable (not included, product code EDN12H-MF)
from the DB9 male RS-232 IN port of the highest-numbered unit in the chain
(the one attached to the DTE) to the DB9 female RS-232 OUT port of the
next-highest-numbered unit. Repeat this process for each additional unit in
the daisychain, finishing by connecting the last such cable to the RS-232 OUT
of unit #1. If you include only 8-Line units, there can be eight total units in
your daisychain serving up to 64 total lines. If you include any 4-Line units,
you can serve up to 32 total lines; the maximum number of 4-Line units in
your daisychain will be eight minus twice the number of 8-Line units present:
• No 8-Line units = eight 4-Line units.
• One 8-Line unit = six 4-Line units.
• Two 8-Line units = four 4-Line units.
• Three 8-Line units = two 4-Line units.
• If you use four or more 8-Line units, you can’t include any 4-Line units.
7. Attach the output cord of each Caller ID unit’s power supply to the Power
connector on the back of the unit.
8. Plug each power supply’s input cord into a working AC outlet. The
corresponding Caller ID unit should power up immediately (it has no
ON/OFF switch) and light its Power LED.
9. Plug in and boot up the DTE device attached to the (first) Caller ID unit. If
the DTE is a PC, run its terminal-emulator program. Make sure the DTE or
the terminal-emulator program are set to receive RS-232 data using the same
data rate and data format that the Caller ID unit is set for (see Section 3.2).
Your Caller ID system should now be ready for continuous operation.

CHAPTER 5: Operation
5. Operation
NOTE
We recommend that the first time you start up your Caller ID system,
you test it as described in Section 6.1.
5.1 LEDs
There are two LEDs on the front panel of each Caller ID unit. One is the Power
LED, which lights as soon as the unit starts receiving power. The other is the DATA
LED, which flashes to show that data is being sent from the Caller ID unit to the
DTE. (A unit won’t light its DATA LED unless it’s connected to a powered DTE—
specifically, it needs to receive Pin 7, RTS, active/high on its RS-232 OUT port.)
5.2 How the Unit Handles Caller ID Information
The Caller ID unit receives standard Caller ID information from the telephone
company’s central office as Bell
®
202A modem tones, between the first and second
rings of the phone call. The Caller ID unit takes this information, formats it as an
ASCII text record (as shown in Figure 5-1), prefaces it with the number of the port
on which the call was received, and sends it from its RS-232 OUT port to the DTE.
NOTE
If handshaking between the Caller ID system and the DTE is prolonged,
data could be lost.

(not actual width—filler spaces compressed).

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.

CHAPTER 6: Troubleshooting
6. Troubleshooting
6.1 Testing
To test your Caller ID system, take these steps:
1. Go off-hook from an outside test line and dial the phone number of the
Caller ID system line you want to test.
2. Between the first and second rings of the phone call, the Caller ID unit’s
DATA LED should flash and the Caller ID information should be displayed or
printed by the DTE.
3. Hang up the test line.
4. Repeat steps 1 through 3 for all of the system’s phone lines.
6.2 Things to Try
Here are some problems that can occur in a Caller ID system along with some
possible causes/solutions you might want to investigate.
The Power (PWR) LED on a Caller ID unit doesn’t light.
• Make sure the power supply is securely connected to the Caller ID unit and is
plugged into a working AC outlet.
• Try to place a call to one of the lines attached to that Caller ID unit. If the
system behaves normally otherwise, that LED is defective. If the call, or the
Caller ID data, is delayed or lost, or if the unit doesn’t respond at all,
something else in the unit is defective. Call Black Box Tech Support as
described in Section 6.3.
Caller ID data for some or all lines isn’t printed or displayed at the DTE.
• Are the PWR and DATA LEDs of the Caller ID unit(s) attached to the affected
line(s) lit/flashing? If not, see “The Power LED doesn’t light” above.
• Make sure the cable between the DTE and the (first) Caller ID unit’s RS-232
OUT port is properly pinned and securely connected.
• If you’re daisychaining, make sure all of the system’s RS-232 OUT to RS-232 IN
cables are properly pinned and securely connected.
• Make sure that the data rate and data format settings of your Caller ID units
match those of the DTE and each other (see Section 3.2).
26
4- AND 8-LINE CALLER ID
Caller ID data for some or all lines is garbled.
• Make sure that the data rate and data format settings of your Caller ID units
match those of the DTE and each other (see Section 3.2).
• If only one of the four or eight lines of a Caller ID unit is malfunctioning,
check the unit’s DATA LED to see if it flashes when data is sent. If it isn’t,
there might might be a problem with the RTS signal, or there might be a
hardware fault somewhere.
• If you’re daisychaining, make sure that the unit numbers of all of the Caller ID
units are set correctly (see Section 3.2).
6.3 Calling Black Box
If you determine that your Caller ID unit is malfunctioning, do not attempt to alter or
repair it. It is not user-serviceable. Contact Black Box Technical Support at 724-746-
5500.
Before you do, make a record of the history of the problem. We will be able to
provide more efficient and accurate assistance if you have a complete description,
including:
• the nature and duration of the problem;
• when the problem occurs;
• the components involved in the problem;
• any particular application that, when used, appears to create the problem or
make it worse; and
• the results of any testing you’ve already done.
6.4 Shipping and Packaging
If you need to transport or ship your Caller ID unit:
• Package it carefully. We recommend that you use the original container.
• If you are returning the unit, include everything you received with it. Before
you ship the unit back to Black Box for repair or return, contact us to get a
Return Authorization (RA) number.
