2.2 DESCRIPTION
The Model 1080ARC Series Universal Short Range Modem
2-wire (half duplex) or 4-wire (full or half duplex), in synchronous or asynchronous modes at an extended range of 20 miles. It operates at 12
switch-selectable data rates to 57.6 kbps. The Model 1080ARC always
operates in sync. mode between the local and remote modems; when
connected to an async. RS-232 device, the Model 1080ARC converts
the async. data to sync. data.

operates
The Model 1080ARC has several features to enhance overall performance: automatic equalization, automatic gain control, antistreaming
timer, transformer isolation and Silicon Avalanche Diode surge protection. The Model 1080ARC features V.52 compliant bit error rate pattern
tests and two V.54 test modes.
The Model 1080ARC is designed to mount in Patton’s 2U high 19” rack
chassis. This 16-card chassis has a switchable 120/240 volt power supply and mounts cards in a mid-plane architecture: The front card can be
plugged into different rear cards. This means that the Model 1080ARC
card can have several interface options and can be switched with other
Patton short haul cards.

3.0 CONFIGURATION
This section describes the location and orientation of the Model
1080ARC’s configuration switches and provides detailed instructions on
setting each of the switches.
The Model 1080ARC uses a unique package of 24 DIP switches that
allow configuration to an extremely wide range of applications. These 24
DIP switches are accessible when the card is slid out of the rack chassis.
Once configured, the Model 1080ARC is designed to operate transparently, without need for frequent re-configuration.
3.1 SWITCH LOCATIONS AND ORIENTATION
The Model 1080ARC has three sets of eight switches—S1, S2, and S3—
which are mounted on the PC board (Figure 1). These configuration
switches allow you to select data rates, clocking methods, V.52 & V.54
tests, word lengths, extended signaling rates, async. or sync. mode, 2- or
4-wire operation, antistream control and input impedance. As Figure 2
shows, the orientation of all DIP switches is the same with respect to
“ON” and “OFF” positions.

3.2 CONFIGURATION SWITCH SET “S1”
The DIP switches on S1 set data rate, clock source, async./sync. mode
and carrier control method. The default settings are summarized in
Table 1.
Table 1:
Summary of DIP switch default settings for set S1
Position Function Factory Default
S1-1 Data Rate On 9,600 bps
S1-2 Data Rate Off 9,600 bps
S1-3 Data Rate Off 9,600 bps
S1-4 Data Rate On 9,600 bps
S1-5 Clock Source On Internal
S1-6 Clock Source On Internal
S1-7 Async./Sync. On Async.
S1-8 Carrier Control Off Constantly On
S1-1 through S1-4: Data Rate Setting
Switches S1-1 through S1-4 are set in combination to determine the
asynchronous and synchronous data rate for the Model 1080ARC (see
Table 2).
Table 2:
S1-1 through S1-4: Data Rate Settings

S1-5 and S1-6: Clock Source
Switches S1-5 and S1-6 are set in combination to determine the transmit
clock source for the Model 1080ARC (see Table 3).
Table 3:
S1-5 and S1-6: Clock Source Settings
S1-5 S1-6 Setting
On On Internal transmit clock
Off On Receive recover clock
On Off External transmit clock
S1-7: Asynchronous/Synchronous Mode
The setting for switch S1-7 determines whether the Model 1080ARC is in
asynchronous or synchronous operating mode (see Table 4).
Table 4:
Asynchronous/Synchronous Mode Settings
S1-7 Setting
On Asynchronous
Off Synchronous
S1-8: Carrier Control Method
The setting for switch S1-8 determines whether the carrier is “constantly
on” or “controlled by RTS”. This setting allows for operation in switched
carrier, multipoint and/or hardware handshaking applications (see
Table 5).
Table 5:
Carrier Control Method Settings
S1-8 Setting
Off Constantly on
On Controlled by RTS

3.3 CONFIGURATION SWITCH SET S2
The DIP switches on S2 set word length, extended signaling rate, RTS/
CTS delay, V.52 & V.54 diagnostic tests and 2- and 4-wire operation.
The default settings are summarized in Table 6.
Table 6:
Summary of DIP switch default settings for S2
Position Function Factory Default
S2-1 Not Used N/A
S2-2 2-Wire/4-Wire Off (4-Wire)
S2-3 V.52/V.54 Tests Off (Normal Operation)
S2-4 RTS/CTS Delay On (7 ms)
S2-5 RTS/CTS Delay On (7 ms)
S2-6 Extended Signaling Rate Off (-2.5% to 1%)
S2-7 Word Length Off (10 bits)
S2-8 Word Length Off (10 bits)
S2-2: 2-Wire/4-Wire Mode Selection
The setting for switch S2-2 determines whether the Model 1080ARC is
operating in 2-wire or 4-wire mode (see Table 7).
Table 7:
2-Wire/4-Wire Mode Selection Settings
S2-2 Setting
Off 4-wire (full or half duplex)
On 2-wire (half duplex only)
S2-3: V.52 and V.54 Diagnostic Test
To reset the V.54 circuit, set switch S2-3 to the “ON” position, then back
to the “OFF” position (see Table 8).
Table 8:
V.52 and V.54 Diagnostic Test Settings
S2-3 Setting
Off Normal Operation
On Test Disabled
11
S2-4 and S2-5: RTS/CTS Delay
The combined settings for switches S2-4 and S2-5 determine the
amount of delay between the time the Model 1080ARC “sees” RTS and
when it sends CTS. Options are no delay, 7 ms and 53 ms (see Table 9).
Table 9:
RTS/CTS Delay Settings
S2-4 S2-5 Setting
On On 7 ms
On Off 53 ms
Off On No delay
Off Off No delay
S2-6: Extended Signaling Rate
The setting for switch S2-6 determines the range of variability the Model
1080ARC “looks for” in asynchronous data rates (i.e., the actual variance
from a given frequency level the Model 1080ARC will tolerate (see
Table 10).
Table 10:
Extended Signaling Rate Settings
S2-6 Setting
Off -2.5% to +1%
On -2.5% to +2.3%
S2-7 and S2-8: Word Length
Switches S2-7 and S2-8 are set in combination to determine the word
length for asynchronous/synchronous data (see Table 11).
