Note
When setting the 1082 for SNMP Management, the DTE rate
switches (S1-1,S1-2, and S2-1) must be also set to the ON position. Therefore, to set a 1082 unit SNMP Mangagement mode, the
following s witches ha v e to be at the ON position, S1-1, S1-2, S2-1.
Switches S1-1 and S1-2: Data Rate
Use switches S1-1 and S1-2 to configure the asynchronous or synchronous data rate of the Model 1082 and Model 1082/144. Each setting represents one synchronous data rate and one asynchronous data rate.
S1-1 S1-2 Sync Data Rate Async. Data Rate
On On 32 kbps Reserved
Off On 56 kbps Reserved
On Off 64 kbps Reserved
Off Off 128 kbps (see note) 0–38.4 kbps
Off Off 144 kbps or 19.2 kbps (see note) Reserved
Note
The Model 1082 can also operate at the 19.2 kbps synchronous
rate, and the Model 1092/144 can also operate at the 144 kbps
synchronous rate. To operate at these rates, set switches S1-1
and S1-2 both to the OFF position and Switch S2-1 to the ON
position (see section , “Configuring DIP switch S2” on page 122
for a description of Switch S2-1).
If the S2-1 switch is positioned in the OFF position, the 128 kbps
sync data rate/0–38.4 kbps async data rate option is selected.
Switch S1-3: Data Set Ready during Line Loopback Test
Use Switch S1-3 to control the behavior of the DSR signal at the EIA
interface during the line loopback test.

nal interface
On Off Receive Recover System clock derived from the
received line signal
Off Off Hardware Reset
A pair of Model 1082s communicate synchronously
across the twisted pair line connection. Therefore,
you
must set these switches whether your application is
async or sync
. For X.21 or Async applications, configure
one Model 1082 for internal clock mode and the other
Model 1082 for receive recover clock mode.
Important

4.1 CONNECTING THE TWISTED PAIR INTERFACE
The Model 1082 supports communication between two DTE devices at
distances to 5 miles (8 km) over 24 AWG (.5mm) twisted pair wire. Two
things are essential:
1. These units work in pairs. Both units at the end of the twisted pair
DSL span must be set for the same DTE rate.
2. To function properly, the Model 1082 needs one twisted pair of
metallic wire. This twisted pair must be unconditioned, dry, metallic
wire, between 19 (.9mm) and 26 AWG (.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.
15
The RJ-45 connector on the Model 1082’s twisted pair interface is polarity insensitive and is wired for a two-wire interface. The signal/pin relationships are shown in Figure 5.
Figure 5.

4.2 CONNECTING THE MODEL 1082 (V.35) SERIAL INTERFACE
Model 1082 supports V.35 serial port connections. This section
describes how to connect the serial ports to your V.35 equipment.
Connecting the Model 1082 (V.35) to a DTE Device
The Model 1082 provides a V.35 DCE (Data Circuit Terminating Equipment) interface on an M/34 f emale connector. As a DCE, this interface is
designed to connect to DTE equipment, such as a router. When connecting the V.35 interface of the Model 1082 to your DTE device, use a V.35
straight-through cable (see Figure 6). Appendix C, “Model 1082C and
1082D Interface Pin Assignments” on page 28 describes pin assignments and signal sources for the Model 1082 V.35 interface. When purchasing or constructing an interface cable, please refer to the pin
diagrams in Appendix C as a guide.

designed to connect to DTE equipment, such as a router. However, tailcircuit applications require connection to another DCE equipment, such
as a multiplexer (see Figure 7). When connecting the V.35 interface of
the Model 1082 to your DCE device , use a V.35 null modem cable. Some
applications may also require the installation of a V.35 tail-circuit buff er to
account for small differences in clock frequency between the 1082 and
the V.35 DCE (Multiplexer).

Model 1082 supports X.21 serial port connections. This section
describes how to connect the serial ports to your X.21 equipment.
Connecting the Model 1082 (X.21) to a “DCE” or “DTE” Device
The Model 1082 provides an X.21 interface on a DB-15 f emale connector.
The X.21 interface def ault configuration is DCE (Data Circuit T erminating
Equipment) for connection to DTE (Data Terminal Equipment) such as a
router. However , the X.21 interf ace on the Model 1082 may be configured as
DTE (Data Terminal Equipment) for connection to DCE such as a modem or
17
multiplex er. When connecting the X.21 interf ace of the Model 1082 to y our
DTE device, use a X.21 straight through cab le (see Figure 8).

5.0 OPERATION
Once the Model 1082 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
To apply power to the Model 1082, first be sure that you have read “Connecting Power” on page 19, and that the unit is connected to the appropriate power source. Then power-up the unit.
5.2 LED STATUS MONITORS
The Model 1082 features six front panel LEDs that monitor power, the
DTE signals, network connection and test modes. Figure 12 shows the
front panel location of each LED. See also, LED description Table 1.

5.3 TEST MODES
The Model 1082 offers two proprietary loopback test modes, plus a builtin V.52 BER test pattern generator, to evaluate the condition of the
modems and the communication link. These tests can be activated physically from the front panel, or via the interface.
Local Line Loopback (LLB)
The Local Line Loopback (LLB) test checks the operation of the local
Model 1082, and is performed separately on each unit. Any data sent to
the local Model 1082 in this test mode will be echoed (returned) back to
the user device (see Figure 13). For example, characters typed on the
keyboard of a terminal will appear on the terminal screen.
LLB initiated
Figure 13. Local Line Loopback
To perform an LLB test, follow these steps:
1. Activate LLB. This may be done in one of three ways:
— Move the front panel toggle switch up to “Local”.
— Raise the LLB signal on the interface (see Appendix C, “Model
1082C and 1082D Interface Pin Assignments” on page 28).
Once LLB is activated, the Model 1082 transmitter output is connected to its own receiver. Data is also looped back to the line. The
TM
LED should be lit.
2. Verify that the data terminal equipment is operating properly and
can be used for a test.
3. Perform a V.52 BER (bit error rate) test as described in “Using the
V.52 (BER) test pattern generator” on page 24. If the BER test
equipment indicates no faults, b ut the data terminal indicates a fault,
follow the manufacturer’s chec k out procedures for the data terminal.
Also, check the interface cable between the terminal and the
Model 1082.
22
Remote Digital Loopback (RDL)
The Remote Digital Loopback (RDL) test checks the perf ormance of both
the local and remote Model 1082s, and the communication link between
them. Any characters sent to the remote Model 1082 in this test mode
will be returned back to the originating device (see Figure 14, below). F or
example, characters typed on the keyboard of the local terminal will
appear on the local terminal screen after having been passed to the
remote Model 1082 and looped back.

Do not
send a 511 test pattern from the test equipment
when you connect external test equipment to the 1082.
Important
To perform an RDL test, follow these steps:
1. Activate RDL. This may be done in three ways:
— Move the front panel toggle switch down to
Remote
.
— Raise the RDL signal on the interface (see Appendix C , “Model
1082C and 1082D Interface Pin Assignments” on page 28).
Note Remote loopback cannot be activated until approximately 45
seconds after the two modems have linked to each other.
2. Perform a V.52 BER test as described in “Using the V.52 (BER) test
pattern generator” on page 24. If the BER test equipment indicates
a fault, and the Local Line Loopback test was successful for both
Model 1082s, you may have a problem with the twisted pair line
between the modems. You should then check the twisted pair line for
proper connections and continuity.
Note The Remote Digital Loopback (RDL) will not work for 144 kbps.
You must first set the units to 128 kbps or slower to use the RDL.
23
Using the V.52 (BER) test pattern generator
To use the V.52 BER tests in conjunction with the Remote Digital Loopback tests (or with Local Line Loopback tests), do the following:
1. Locate the
511/511E
toggle switch on the front panel of the
Model 1082 and set the toggle to the down position. This activates
the V.52 BER test mode and transmits a
loop. If any errors are present, the local modem’s red
511
test pattern into the
ER
LED will
blink continuously.
2. If the above test indicates that no errors are present, move the V.52
toggle switch to the up position, activating the 511/E test with errors
present. If the test is working properly, the local modem’s red
ER
LED will blink. A successful 511/E test will confirm that the link is in
place, and that the Model 1082’ s b uilt-in 511 gener ator and detector
are working properly.
