1.2 RADIO AND TV INTERFERENCE
The Model 2094 generates and uses radio frequency energy, and
if not installed and used properly—that is, in strict accordance with the
manufacturer's instructions—may cause interference to radio and television reception. The Model 2094 has been tested and found to comply with the limits for a Class Acomputing device in accordance with
the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that interference will not occur in a particular installation. If the Model 2094 does
cause interference to radio or television reception, which can be determined by disconnecting the cables, the user is encouraged to try to
correct the interference by one or more of the following measures:
moving the computing equipment away from the receiver, re-orienting
the receiving antenna, and/or plugging the receiving equipment into a
different AC outlet (such that the computing equipment and receiver
are on different branches).
1.3 CE NOTICE
The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the Union European
(EU). ACertificate of Compliance is available by contacting Technical
Support.

2.2 GENERAL PRODUCT DESCRIPTION
The Patton Model 2094 V.35 to E1/Fractional E1 Converter connects
equipment with standard ITU-T V.35 Interfaces to 2.048 Mbps G.703
E1 (clear channel) and fractional E1 G.704 (n x 64) 4-wire 120 ohm
interfaces. Housed in our MicroPak enclosure measuring only 9x 5.3 x
2 cm (3.55 x 2.1 x 0.78 in.) the Model 2094 plugs directly into the V.35
DTE interface of a router, switch, FRAD, multiplexer or other networking device.
The Model 2094 supports all necessary G.703/G.704 diagnostics, DTE
local/remote loops, and V.54 loop up/loop down. Diagnostics are initiated via the Model 2094's control port, or through the DTE or line interfaces. Easily readable LED indicators include TD, RD, Loss of Sync
(LOS), Alarm, Error, Test and Power. Configuration of the Model 2094
is done through the control port or using DIP switches.
The Model 2094 presents a RJ48C 120 ohm interface to the line and a
V.35 interface to the customer's device using a Male M/34 connector.
An M/34 to DB-60 adapter cable is available for convenient connection
to Cisco routers. The Model 2094 is powered by an external Universal
Input 100-240VAC adapter.

2.3 SUPPORTED APPLICATIONS
The Model 2094 provides an E1 network termination between E1
and Fractional E1 equipment and customer premises equipment (CPE)
such as a router. The Model 2094 can also be used as a high-speed
short haul modem for campus applications.
2.3.1 The 2094 as the Interface between the Telco and CPE
The Model 2094 provides the interface between an E1/Fractional
E1 multiplexer and a router or switch (See below).
2.3.2 The 2094 as a High-Speed Short Range Modem
The Model 2094 can also be installed into high-speed campus
applications. In this application, a pair of Model 2094 units operate as
short range modems (See below).

Switch SW1: Line Coding
Use Switch SW1 to control the Network Line Coding options. Set
these options to be the same as the Line Coding given to you by your
Service Provider. If you are using two Model 2094s together as short
range modems, set both units to HDB3.
SW4 Line Framing & Coding
Off HDB3
On AMI
Line Coding Options:
High Density Bipolar 3 (HDB3): In HDB3 coding, the transmitter
deliberately inserts a bipolar violation when excessive zeros
in the data stream are detected. The receiver recognizes
these special violations and decodes them as zeros. This
method enables the network to meet minimum pulse density
requirements. Use HDB3 unless AMI is required in your
application .
Alternate Mark Inversion (AMI): AMI coding does not inherently
account for ones density. To meet this requirement, the user
should ensure that the data inherently meets pulse density
requirements.

3.0 CONFIGURATION
The Model 2094 features configuration capability via hardware
switches or a software control port. This section describes all possible
hardware and software switch configurations of the Model 2094.
3.1 DIP SWITCH CONFIGURATION
The Model 2094 has eight internal DIP switches that allow configuration for a wide range of applications. The eight switches are
accessed by opening the plastic case with a small screwdriver. Figure
1 (below) shows the location of the DIP switches on the bottom of the
printed circuit board.
The Model 2094 DIP switches (Switches SW1 - SW8) can be configured as either “On” or “Off”. Figure 2 (below) shows the orientation
of the DIP switches with respect to ON/OFF positions.
Default positions for Switches SW1-SW8 are shown in the table on
the following page. Descriptions of each switch follow the table.

CLOCK MODES
Network Clock Transmitter timing is derived from the received line
signal.
Internal Clock Transmitter clock is derived from an internal clock
source.
External Clock Transmitter timing is derived from the local DTE
device. Valid only in unframed mode.
Note: When using the 2094 as a high-speed short range modem, one
unit of the link must be configured in either internal or external clock,
and the other end must be configured for network clock mode.
Switches SW5, SW6, SW7, and SW8
Use Switches SW5, SW6, SW7, and SW8 to set the DTE data rate.

Switch SW2: CAS Multiframe
The Channel Associated Signaling (CAS) multiframe uses Timeslot 16
(TS16) to send multiframe (MF) alignment data. In CAS MF, a multiframe is defined as 16 frames, where a frame consists of 32 64kb/s
timeslots, numbered 0 to 31. TS16 of the first frame in the MF contains
the CAS MF alignment word in the upper four bits. The alignment word
is always 0000 (binary). The 2094 does not perform any signaling in
TS16 other than to insert the MF alignment word, in order to maintain
MF alignment. When CAS MF is disabled, the unit transmits user data
in TS16; therefore, up to 31 channels are available for user data. When
it is enabled, TS16 is not available to the user. In this case, the user
can use up to 30 channels for data. CAS MF can be used with CRC-4
MF or by itself. When enabled, both units must employ CAS MF; if one
unit is set for CAS MF, and the other is not, the one using CAS MF will
detect a loss of sync.

Off Disabled
On Enabled
Switch SW3 & SW4: CRC-4 Multiframe/Clock Mode
In framed mode, SW3 is used for CRC-4 MF. CRC-4 Multiframe uses
Time Slot zero to carry CRC-4 information. It operates independently of
CAS MF. When CRC-4 is enabled, the unit monitors the incoming data
stream for CRC-4 errors. It transmits CRC-4 error counts to the transmitting unit. Excessive errors may cause loss of frame or loss of sync.
If CRC-4 MF is used, both units must be set for set for CRC-4 MF.
Otherwise, the one using CRC-4 MF will detect loss of sync.
In unframed mode, SW3 is used to along with SW4 to determine the
clock mode. In unframed mode, the model 2094 can be set to network,
internal or external clock mode.
In framed mode SW4 is used alone to determine the 2094 transmitter
timing. In framed mode the 2094 can be set to Network or Internal
clock.
The following charts represent both cases.
