Note
Conformity documents of all Patton products can be viewed
online at www.patton.com under the appropriate product page.
1.1 RADIO AND TV INTERFERENCE
The Model 1088 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 1088 has been tested and found to comply with the
limits for a Class A computing 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 1088 does cause interference to radio
or television reception, which can be determined by disconnecting the
unit, 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).
1.2 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 European Union (EU). A Certificate of Compliance is available by contacting Technical Support.

2.2 DESCRIPTION
The Patton Electronics mDSL Rock et provides high speed 2-wire connectivity to ISPs, PTTs, and corporations using mDSL (Multi-rate Symmetric Digital
Subscriber Line) technology . Multi-rate DSL offers the ability to deliv er the
maximum bit rate that a twisted pair line can accommodate. Supporting multiple line rates from 144 kbps to 2.320 Mbps, the NetLink provides “megabyte” speeds to leased line , LAN to LAN interconnection, and WAN access
networks over 3.6 miles/5.8 km (1.054 Mbps on 24A WG/.5 mm wire).
Model 1088/C provides a V.35 interface on an M/34 female connector. Model
1088/D provides an X.21 interface on a DB-15 f emale connector. F eatures
include loopback diagnostics, SNMP/HTTP remote management capabilities
using NetLink Plug-and-Play and inband externally accessible configuration
switches. All versions of the Rock et are compatible with Patton’s popular
Model 1095 standalone and 1095RC rack card.
As a symmetric DSL NTU, NetLinkTM mDSL offers the same data rates in
both directions over a single pair of regular telephone lines using Carrierless
Amplitude and Phase (CAP) modulation. Line connection is made b y an RJ45 jack. Standard v ersions of Model 1088 are pow ered b y a 100/230 V A C
(Universal) supply. The DC power supply option supports any DC input
between 36–72 VDC .

3.0 CONFIGURATION
The Model 1088 is equipped with two sets of eight DIP switches, which allow
configuration of the unit for a wide variety of applications. This section
describes switch locations and explains all possible configur ations.
3.1 CONFIGURING THE HARDWARE DIP SWITCHES
The 16 external switches are grouped into two eight-s witch sets , and are
externally accessible from the underside of the Model 1088 (See
Figure 1).

The two sets of DIP switches on the underside of the Model 1088 will be
referred to as S2 and S3. As Figure 2 shows, the orientation of all DIP
switches is the same with respect to “ON” and “OFF” positions.

Configuration DIP Switch Set “S2”
Switches S1-1 through S1-8 may be used to configure CO/CP operation,
line framing and coding, CRC-4 operation, and DTE initiated loop diagnostics. Default settings of S1 switches are shown in Table 1.

Switch S2-8: Enable/Disable Loop Tests from DTE.
Switch S2-8 may
be used to allow Model 1088/C to enter loopback diagnostic tests (Local
or Remote) when the V.35 DTE raises the appropriate loop request pin
(LLB: Pin L or RDL: Pin N). When Switch S2-8 is in the On position, the
Model 1088/C will enter Local Loopback or Remote Loopback at the
request of the DTE. When Switch S2-8 is in the Off position, the Model
8
1088/C ignores DTE loop requests. In the Off position, loop requests
may still be initiated by the front panel switch.

Configuration Switch Set “S3”
Use the six DIP Switches in Switch S3 to enable the DTE bit rate. The
following table summarizes default positions of DIP Switch S3. Detailed
descriptions of each switch follow the table.

Note
Based on the DTE rate chosen, the Model 1088 will automatically select the optimum line rate depending on distance and
line conditionsfor the distance. The line selection will be based
on the lowest line rate that will support the DTE rate.
Switch S3-7: Reset Software Defaults.
Switch S3-7 allows the user to
reset the software configured factory defaults. This will only be needed
when using the Model 1001MC to SNMP manage your units. For more
information, please refer to the Model 1001MC Operations Manual.
