2.2 DESCRIPTION
The Patton Model 1052 is a high speed, A C powered short range modem
that is able to operate synchronously or asynchronously—full duplex—
over a single twisted pair. Supporting data rates up to 128 kbps (synchronous) or 38.4 kbps (asynchronous), the Model 1052 is capable of
point-to-point distances up to 5 miles (8 km) using 24 AWG wire. The
Model 1052 supports internal, external or receive loopback clocking in
synchronous mode. Data rates and asynchronous data format may be
configured locally using DIP switches.
The Model 1052/A provides an RS232 interface on a DB-25 female connector. Line connection is made by an RJ-45 jack. Standard versions of
Model 1052 are powered by a 100–240 VAC (Universal) supply. The DC
power supply options support either -12, -24, or -48 VDC.

3.0 CONFIGURATION
The Model 1052 is equipped with 16 DIP switches that enable configuration of the unit for a wide variety of applications. This section describes
switch locations and explains the different config-urations
3.1 CONFIGURING THE HARDWARE DIP SWITCHES
S1 and S2 each contain eight internal DIP switches (see Figure 1) that
are used for configuration reset purposes only. To access switch set
SW1, use a small flat blade screwdriver to open the Model 1052’s case
as shown in Figure 2 on page 8.

4.1 CONNECTING THE TWISTED PAIR INTERFACE
The Model 1052 supports communication between two DTE devices at
distances to 5 miles (8 km) over 24 AWG (0.5mm) twisted pair wire. Two
things are essential:
• These units work in pairs. Both units at the end of the twisted pair DSL
span must be set for the same DTE rate.
• To function properly, the Model 1052 needs one twisted pair of metallic
wire. This twisted pair must be unconditioned, dry, metallic wire,
between 19 (0.9mm) and 26 AWG (0.4mm) (the higher number
gauges will limit distance). Standard dial-up telephone circuits, or
leased circuits that run through signal equalization equipment, or standard, flat modular telephone type cable, are not acceptable . The RJ-45
connector on the Model 1052’s twisted pair interf ace is polarity insensi-
12

tive and is wired for a two-wire interface. The signal/pin relationships
are shown in Figure 4.

4.2 CONNECTING THE CONNECTING THE MODEL 1052/A
(RS-232)
The Model 1052/A supports RS-232 serial port connections. This section
describes how to connect the serial ports to your RS-232 equipment.
Connecting the Model 1052/A (RS-232) to a DTE Device
The Model 1052/A provides an RS-232 DCE (data communications
equipment) interface on a DB-25 female connector. As a DCE, this interface is designed to connect to DTE equipment, such as a router. When
connecting the RS-232 interface of the Model 1052/A to your DTE
device, use an RS-232 straight-through cab le (see Figure 5). Appendix C
on page 19 describes pin assignments and signal sources for the Model
1052/A RS-232 interface. When purchasing or constructing an interface
cable, use the pin diagrams in Appendix C as a guide.

Universal AC Power (100–240 VAC)
The Model 1052 uses a 5VDC, 2A universal input 100-240VAC, power
supply (center pin is +5V). The universal input power supply has a male
IEC-320 power entry connector. This power supply connects to the
Model 1052 by means of a barrel jack on the rear panel. Many international power cords are available for the universal power supply (Refer to
Appendix B on page 18 for country-specific power cords. The Model
1052 powers up as soon as it is plugged into an AC outlet—there is no
power switch.The Universal AC supply is equipped with a male IEC-320.
DC Power
The optional -12, -24, or -48 VDC DC-to
-
DC adapter supplied with the
DC version of the Model 1052 plugs in a DC source (nominal -12, -24, or
-48 VDC) and plugs into the barrel power supply jack on the rear of the
1052. Refer to Figure 6 to make the proper connection.

5.0 OPERATION
Once the Model 1052 is properly configured and installed, it should operate transparently. This sections describes power-up, reading the LED
status monitors, and using the built-in loopback test modes.
5.1 POWER-UP
Before applying power to the Model 1052, read section 4.3, “Power Connection” on page 13 to ensure that the unit is connected to the appropriate power source.
5.2 LED STATUS MONITORS
The Model 1052 features five side panel LEDs (see Figure 7). Table 2
describes the function of each LED.

Table 2:
LED descriptions
LED Description
TXD (Active: Green) When lit, indicates data transmission.
RXD (Active: Green) When lit, indicates data transmission.
DSL LINK (Active: Green) When lit, indicates that the end-to-end DSL
framer link is up, signifying that the link across the DSL span
is active. The DSL Link LED is off when the link is down.
NS (Active: Yellow) When the No Signal LED is lit, it indicates
that the local Model 1052 is not connected with the remote
Model 1052
ER
(Active: Red) Flashing red indicates that there are CRC errors
on the DSL (framer) side if the DSL Link is active. ER flashes
once to indicate a CRC error during normal operation
