4. STANDALONE 
DATASET 2103
Description
4.01A Standalone DATASET 2103 is packaged in a flat case which
can be placed under a standard desk telephone set. It is func-
tionally the same as the Rack Mounted 
DATASET 2102 (they share the
same base pcb). The Standalone 
DATASET 2103 can be connected to
the PABX using a four-wire connection; two wires connect the
DATASET to the Digital Line Card, and two different wires connect the
telephone set tip-ring pair to an ONS or COV line card; it may also be
connected to a Digital Line Card within the PABX by a single twisted
pair (the telephone set is connected independently). Figure 4-1 shows
a Standalone 
DATASET 2103, while Figure 4-2 shows typical applica-
tions of a Standalone 
DATASET 2103 connected to a telephone set and
a personal computer or terminal.

INSTALLATION OF A STANDALONE 
DATASET 2103
StepAction
1.Install a Standalone DATASET 2103 by placing it near its associated telephone
set and data peripheral (its case is designed to lie flat on the desk under a
standard telephone set).
2.Complete Customer Data Entry for the system to allow the Standalone
DATASET 2103 to operate with the PABX.
3.
4.Set the eight DIP switches as required for this installation. Refer to Table 2-l.
Connect the telephone set cord to the jack marked PHONE; connect the
modular telephone line cord to the jack marked LINE and to the wall or floor
jack which connects to the PABX main distributing frame (MDF). The connection
to the MDF is a four-wire circuit; the voice tip and ring (red and green) connect
to an ONS or COV line card (depending on the type of set being used), and the
DATASET tip and ring (yellow and black) connect to a Digital Line Card.
5.An alternative tip and ring wiring arrangement is: connect the telephone set
through a two-wire connection via the MDF to its ONS or COV line card;
connect the modular line cord (data tip and ring) to the jack of the Standalone
DATASET 2103 marked LINE, through the MDF to its Digital Line Card in the
PABX.
6.Plug the power supply into an ac outlet and its cord into the power socket on
the Standalone 
DATASET 2103. All LEDs should flash 5 times, indicating that the
DATASET has passed its self-test. If this does not happen, the DATASET is
faulty and must be replaced. Then the POWER LED comes on, to indicate that
the data set is communicating with the PABX. If the POWER LED flashes, check
the wiring.
7.Plug the RS-232 interconnecting cable into the RS-232 connector at the back
of the Standalone 
DATASET 2103 and connect its other end to the peripheral
device. When the RS-232 connector is attached, the DEVICE LED should be on,
unless the device is an auto-answer device, and defined as such in CDE
(usually only destination devices such as host computers are auto-answer). If
the device is not auto-answer, and the DEVICE LED does not come on, make
sure the device is powered on, and then use an RS-232 break-out box to verify
that the device provides DTR. If the device does not provide DTR, select CDE
option “RS-232 Force High” for that device.
CAUTION: If ATTN and DISC keys are both pressed at the same time, the 
DATASET 2103 goes
into a special test sequence, generating many error conditions which are displayed
on the terminal that is connected to the 
DATASET 2103. To exit from this sequence,
disconnect and reconnect the data set power cord. These keys should NEVER be
pressed concurrently.

5. CIRCUIT DESCRIPTION
General
5.01The DATASET 2100 Series circuit contains six basic blocks, as
shown in Figure 5-l. The microcontroller is the central proces-
sor for the data set; it contains two timers, the BAUD rate generator,
and the Universal Asynchronous Receiver Transmitter (UART) and the
system High-level Data Link Control (HDLC). The switches on the data
set interface directly to the microcontroller; this way, the firmware can
override the switch settings.
5.02The serial/parallel converter converts serial data from the 
RS-232 port to parallel for the processor, and parallel data from the
processor to serial for the RS-232 port. In asynchronous mode, the
microprocessor does the conversion; in synchronous mode, shift reg-
isters and latches interface the 
TxD and RxD lines with the databus to
the processor.
5.03The Phase Lock Loop and Clock circuits synchronize the receive
data rate of the data set to the rate of the received data from
the other device.
5.04The 
DNIC Interface Circuit provides the interface to the PABX;
its clock signals operate the data set in either set or system
mode.
5.05 The RS-232 Interface contains the drivers and receivers that
buffer the signal lines. It also contains a 
loopback circuit which
can connect together transmit data from the microcontroller to receive
data to the microcontroller 
(RxD to TxD) for self-testing functions.
5.06The Power Supply receives unregulated ac voltage and rectifies
it to become 
+I2 vdc unregulated, -12 vdc unregulated, and
regulated 
+5 vdc for logic circuits.

6. POWER SUPPLIES
General
6.01The Standalone DATASET 2103 receives its power from a plug-in transformer which supplies 9 
vat to a power connector on
the back of the set. Circuitry within the data set converts this to the
required dc voltages.
6.02 The Rack Mounted 
DATASET 2102 receives 9 vat from the
power supply of the DATASHELF 9100. Circuitry on the card
converts this to the required dc voltages. Refer to Section
MITL9141-753-526-NA, DATASHELF 9100, for further information.
