1.1 RADIO AND TV INTERFERENCE

The Model 1095RC 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 1095RC 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 1095RC
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). In the event the user detects intermittent or
continuous product malfunction due to nearby high power transmitting
radio frequency equipment, the user is strongly advised to take the fol­lowing steps: use only data cables with an external outer shield bond­ed to a metal or metalized connector; and, configure the rear card as
shown in section 3.2 of this manual.

1.2 CE NOTICE

2.2 DESCRIPTION
The Patton Electronics

NetLinkTMmDSL

Model 1095RC Multi-

Rate DSL Modem provides high speed 2-wire connectivity to ISPs,
PTTs, and corporations using mDSL (Multi-rate Digital Subscriber Line)
technology. Multi-rate DSL offers the ability to deliver the maximum bit
rate that a twisted pair line can accommodate. Supporting

multiple line

rates from 144kbps to 2.320Mbps, the NetLink provides “megabit”
speeds to leased line, LAN to LAN interconnection, and WAN access
networks over 3.6 miles/5.8km (1.054Mbps on 24AWG/.5mm wire).

The

NetLink

TM

mDSL

rack card allows

DTE speeds

from 64kbps
to 2.3Mbps in increments of 64kbps. Features include loopback diag­nostics, out-of-band SNMP/HTTP remote management capabilities,
using Model 1000MC, and externally accessible configuration switch­es.

As a symmetric DSL NTU,

NetLink

TM

mDSL

offers the same data
rates in both directions over a single pair of regular telephone lines
using Carrierless Amplitude and Phase (CAP) modulation. The Model
1095RC is designed to fit into Patton’s 2U (3.5”) high rack chassis.
This chassis uses a mid-plane architecture allowing front cards to be
plugged into different rear cards. Please see the Model 1001RP14
manual for more information on the power supply options that are
available.

The NetLink Plug-and-Play feature allows the user to configure the
DTE rate for the link from the rack card at the Central Office. The
stand alone unit at the Customer Premise site will automatically config­ure itself to the DTE rate of the rack card. Other configuration parame­ters fall to the default state. This allows changes in the configuration
to be handled from a single end of the link.

This section describes the location and orientation of the Model
1095RC’s configuration switches and jumpers, and provides detailed
instructions for all possible settings.

3.1 CONFIGURING THE HARDWARE SWITCHES

The Model 1095RC Series front card uses hardware switches for
configuration. There is an interface driver board strap, and three eight­position DIP switches, on the bottom side of the front card (see Figure
1, below).

Figure 2 shows the orientation of the DIP switches with respect to

the “ON” and “OFF” positions.

3.1.1 Reversible Interface Driver Board

The Model 1095RC Series features switchable interface driver
boards that allow a wide range of DTE interface connections. Figure 3
shows the Interface Driver Board on the top of the 1095RC PC board.

Follow the instructions below to select the correct interface for your
application:

1. With the 1095RC front card pulled out of the rack or cluster­box chassis, locate the driver board on the top of the 1095RC
front card.

2. Lift the interface board gently off of the PC board.

3. Locate the correct interface on the bottom of the driver board.
For example, the RS-232/V.35 interface board is marked

“THIS SIDE UP FOR RS-232” on one side and “THIS SIDE
UP FOR V.35” on the other side . Other “single” interface

boards are marked with “FRONT” on one side of the board.

4. Re-orient the interface board into the socket with the appropri­ate interface pointed UP and with the arrow pointing toward
the front panel of the Model 1095RC PC board.

5. Push the Interface Driver Board gently onto the socket and re­install into the rack or cluster system.

3.1.2 Connecting to a “DTE” Device

The serial port on most interface modules (all except the X.21
module) is hard-wired as a DCE. Therefore these modules “want” to
plug into a DTE such as a terminal, PC or host. When making the
connection to your DTE device, use a straight through cable of the
shortest possible length—we recommend 6 feet or less. When pur­chasing or constructing an interface cable, please refer to the pin dia­grams in Appendix C as a guide.

3.1.3 Connecting to a “DCE” Device

If the Model 1095RC interface module is hard-wired as a DCE (all

except the X.21 module), you must use a

null modem

cable when con­necting to a modem, multiplexer or other DCE device. This cable
should be of the shortest possible length—we recommend 6 feet or
less. When purchasing or constructing a null modem interface cable,
use the pin diagrams in Appendix C as a guide.

3.1.4 Configuring the X.21 Interface Module IM2RC/D

The serial port on the X.21 Interface Module is default wired as a
DCE, but may be switched to a DTE. This is done by reversing the ori­entation of the DCE/DTE strap, as described below:

To reverse DCE/DTE orientation, remove the interface module
according to the instructions in Section 3.1.1. The DCE/DTE strap is
located on the top side of the interface module’s PC board. The
arrows on the top of the strap indicate the configuration of the X.21
port (for example, if the DCE arrows are pointing toward the rear card
connector, the X.21 port is wired as a DCE). Reverse the DCE/DTE
orientation by pulling the strap out of its socket, rotating it 180º, then
plugging the strap back into the socket. You will see that the
DCE/DTE arrows now point in the opposite directions, showing the
new configuration of the X.21 port. Reinstall the module according to
the instructions in Section 3.1.1.

NOTE: Pin-out requirements for null modem applications vary

widely between manufacturers. If you have any questions about
a specific application, contact Patton Electronics Technical
Support.

3.1.5 Configuration DIP Switch Set “S1” - Management Address

Switch S1 is used to set the address of the card in the NetLink

Network Management System. When the 1095Rc is installed with a

Model 1001MC, the cards and their remote units can be SNMP man­aged using a standard Network Management Station (NMS) or a stan­dard web browser (Netscape, Internet Explorer). For more information
about setting the address, refer to Appendix a of the Model 1001
Operations Manual.

NOTE: If you are not using your Model 1095RC in a Network
Managed environment, please set all Switch Set S1 switches
to the ON position

3.1.6 Configuration DIP Switch Set “S2”

The configuration switches on S2 allow you to specify the Line
Rate, Clocking Mode and response to DTE Loop Enable. Default set­tings of S2 are shown in the table below.

3.2 NETLINK PLUG-AND-PLAY

The NetLink Plug-and-Play application allows ISPs and PTTs to
quickly upgrade the link speed for a customer without re-configuring
the Customer Premise (CP) Model 1095. It will also allow ISPs and
PTTs to set up all of the configurations at the Central Office (on the
rack cards) before installation of the stand alone units, thus saving
time spent configuring and re-configuring DIP switch settings.

The NetLink Plug-and-Play feature allows the user to configure
the DTE rate for the link from the rack card at the Central Office (CO).
The stand alone unit at the Customer Premise (CP) site will automati­cally configure itself to the DTE rate of the rack card. Other configura­tion parameters fall to the default state. This allows changes in the
configuration to be handled from a single end of the link.

When installing a CO/CP style application, the local end of the link
is comprised of a CO unit (1095 or 1095RC) set to either Internal or
External clocking mode and a CP unit (1095 or 1095RC) set as a
NetLink Plug-and-Play CP.

The NetLink Plug-and-Play CP stand

alone will have all of its DIP switches set to the ON position

(as

indicated below in Figure 4).

When the units are connected, the CP will come up with a prede­fined default configuration (Receive Recovered Clocking). During the
handshaking process between the units, the CO unit will set the DTE
rate/line rate of the CP unit to match its DIP switch configuration set­tings. If the DTE rate for the link requires a change, the change is
needed only at the CO side of the link.

The NetLink Plug and Play application will also work in the man­aged system using the Model 1001MC and 1095RC cards installed in
Patton’s 2U rack system. In this application, the system administrator
can configure the entire rack through the Network Management Station
(NMS) before the stand alone (CP) units are installed. For more infor­mation on the SNMP management of your rack, please refer to the
Model 1001MC Operations Manual.

NOTE: Based on the DTE rate chosen, the Model 1095RC will

automatically select the optimum line rate for the distance. This
selection is based on the lowest line rate that will support the
DTE rate.
