2.2 DESCRIPTION
The NetLinkTM 10BaseT HDSL Rocket (Model 1089) is a Multi-
Rate DSL Modem that provides seamless MAC Layer connectivity
between 2 peered 10BaseT LANs. Now, Enterprise users no longer
need to hassle with a bridge and a CSU/DSU or recurring leased line
costs. The NetLink Rocket allows users to add additional nodes to a
LAN that has reached its maximum distance limits or separate high
traffic areas of a LAN. The Rocket connects peered LANs and auto-
matically forwards and receives LAN broadcasts, multi-casts and
frames across a 2-Wire DSL span.
The NetLinkTM HDSL 10BaseT Rocket features include loopback
diagnostics, inband SNMP/HTTP remote management capabilities
using NetLink Plug-and-Play and externally accessible configuration
switches. As a symmetric DSL modem, the NetLinkTM HDSL Rocket
offers the same data rates in both directions over a single pair of regu-
lar telephone lines using 2B1Q modulation. The Rocket connects to
the DSL line via an RJ-45 jack. Standard power options include
115VAC, 230VAC, Universal (100/240VAC) and any DC input between
36-60VDC.

3.0 CONFIGURATION
3.1.1 Configuration DIP Switch Set “S2”
The Model 1089 has two sets of eight DIP switches, which allow
configuration for a wide variety of applications. This section describes
switch locations and explains all settings.
The only setting for S2 is for Clocking Mode between Model
1089s. All other switches are reserved for factory usage and must
remain in the default configuration. Default settings are shown in the
table below.
3.1 CONFIGURING THE HARDWARE DIP SWITCHES
The 16 external switches are grouped into two eight-switch sets,
and are externally accessible from the underside of the Model 1089, as
shown in Figure 1, below).

Switch S3-1 through S3-6: DTE Rate
Use Switch S3-1 through S3-6 to provision bandwidth to the LAN
in 64kbps increments up to 1.152Mbps. Peak bandwidth utilization on
the local domain on an Ethernet LAN runs typically between 15% to
20% (1.5Mbps to 2Mbps) of the maximum bit rate of 10Mbps. Traffic
between LANs typically runs even lower -- between 2% to 7%
(200kbps to 700kbps) of the maximum bit rate depending upon appli-
cation and environmental conditions. This is the amount of traffic that
will run across the DSL span.

4.0 INSTALLATION
4.2 Connecting the 10Base-T Ethernet Port to a PC (DTE)
When the Model 1089 has been properly configured, it may be
connected to the DSL twisted pair interface, the 10BaseT Ethernet
Interface, and the power source. This section describes these connec-
tions.
The 10Base-T interface is configured as DTE (Data Terminal
Equipment). If the Model 1089 is to to connect to another DTE device
such as a 10Base-T network interface card, construct a 10Base-T
crossover cable and connect the wires as shown in the diagram below.

4.1 CONNECTING THE DSL INTERFACE
4.3 Connecting the 10Base-T Ethernet Port to a Hub
The Model 1089 supports communication between 10BaseT Hubs
or Workstations at distances to 5 miles (8 km) over 24 AWG (.5mm)
twisted pair wire. Two things are essential:
The 10Base-T interface is configured as DTE (Data Terminal
Equipment), just like a 10Base-T network interface card in a PC.
Therefore, it “expects” to connect to a 10Base-T Hub using a straight-
through RJ-45 cable. Use the diagram below to construct a cable to
connect the 10 BaseT interface to a 10Base-T Hub.
1. These units operate as a pair. 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 1089 needs one twisted pair of
metallic wire. This twisted pair must be unconditioned, dry, metal-
lic wire, between 19 (.9mm) and 26 AWG (.4mm) (the higher num-
ber gauges will limit distance). Standard dial-up telephone cir-
cuits, or leased circuits that run through signal equalization equip-
ment, or standard, flat modular telephone type cable, will not work!

5.0 OPERATION
4.4 POWER CONNECTION
Universal AC Power (100-240VAC)
When the Model 1089 has been properly configured and installed,
it should operate transparently. This sections describes power-up,
LED status monitors, and the built-in loopback test modes.
The Model 1089 uses a 5VDC, 2A universal input 100-240VAC,
power supply (center pin is +5V). The universal input power supply
has a male IEC-320 power entry connector. This power supply con-
nects to the Model 1089 by means of a barrel jack on the rear panel.
Many international power cords are available for the universal power
supply (Please refer to Appendix B for country-specific power cords.
5.1 POWER-UP
Before applying power to the Model 1089, please read Section
4.3 and ensure that the unit is connected to the appropriate power
source.
5.2 LED STATUS MONITORS
The Model 1089 powers up as soon as it is plugged into an AC
outlet--there is no power switch.
The Model 1089 features six front panel LEDs that monitor con-
nections on the DSL and 10BaseT links, signaling, error and test
modes. Figure 6 (below) shows the front panel location of each LED.
Descriptions of each LED follow Figure 6.
120 VAC Power (US)
The 100-132 VAC adapter supplied with the U.S. version of the
Model 1089 is a wall mount type and may be plugged into any
approved 120 VAC wall jack.
230 VAC Power (International)
The 230 VAC adapter supplied with the International version of the
Model 1089 is a wall mount type and may be plugged into any
approved 230 VAC wall jack.

The Model 1089 offers a proprietary Remote Loopback test
modes, plus a built-in V.52 BER test pattern generator to evaluate the
communication status between units. Activate this test mode by tog-
gling the Test Mode Switch on the front panel of the unit.
5.3.1 Overview
10BT Link
(Active Green) Solid green indicates that the
10BaseT Ethernet interface has detected a valid
SQE heartbeat, signifying a valid 10BaseT con-
nection.
Figure 8 below shows the major elements used in the loop-back
and 511 pattern tests available in the Model 1089. Each block has sev-
eral functions. Following Figure 7 are descriptions of the elements dur-
ing Test Modes.

TM
(Active Yellow) Solid Yellow indicates an Active
Test Mode. The unit may be placed in test mode
by the local user or by the remote user.
Framer
The framer determines the status of the line. In
normal operation the framer transmits and
expects to receive framed packets from the far
end. If the framer receives framed packets from
the far end, the DSL Link LED will turn on. If
framed packets are not received, the DSL Link
LED will turn off. The restart procedure uses this
information to determine if a valid connection is
made (cable disconnect, poor cable quality, etc).
In normal Data Mode, if the box receives 4 sec-
onds of unframed packets it will restart the box
and begin trying to re-establish a connection
with the the remote Model 1089. The distinction
between framed packets and unframed packets
becomes important when we discuss the Pattern
Generator.
Pattern Gen/Det
This part of the Processor generates and
detects the 511/511E patterns. When transmit-
ting 511 patterns, the information is unframed
13
14
(because it originates after the framer) and is
intended to be evaluated only by another
Processor. If the units are transmitting data and
the pattern generator is enabled on one end of
the link, the far end will begin receiving
unframed packets and assume that the line has
gone down. During test modes, the pattern gen-
erator is forced to time out before it can cause
the DSL link to go down.
Restart Procedure The restart procedure is in place to allow the
and Time Outs
units to re-establish a connection after the
framer begins seeing unframed packets. The
Test Mode Timing Chart below shows the
amount of time the framer must see consecutive
unframed packets before the unit will restart and
try to establish a new line connection. The rea-
son that there are different Restart Times will
become apparent after reading the rest of the
document. The 511/511E Time Out shown refers
to the amount of time the 511/511E pattern will
be valid. At the end of this time the pattern will
automatically turn itself off and the normal data
path will be re-established. The ER led will flash
indicating to the user that the test has timed out.
The ER led will stop flashing once the 511/511E
switch is placed into the normal position.
Loop Control
This part of the Processor is used to control
Remote Loopback test mode. In a Remote
Loop, the 511/511/E data is looped back to the
line and to the remote unit over the DSL span.

5.3.2 Loops and Patterns
The following section describes the Remote Loopback/BER test
modes.
2. If the above test indicates no errors are present, move the
test switch V.52 toggle switch UP, activating the “511/E” test
with intentional errors present. If the test is working properly,
the local unit’s red “ER” LED will blink. A successful “511/E”
test will confirm that the link is in place, and that the Model
1089’s built-in “511” generator and detector are working
properly.
Remote Digital
When Remote Loop/511 or Remote Loop/511/E
is enabled via the front panel switch, the
Remote unit’s Restart Timer is set to one
minute. This is because when the 511/511E
generator is initiated on the local unit, the
Remote framer begins seeing unframed pack-
ets. The Remote unit can not distinguish the
511/511E pattern from the line being disconnect-
ed, so the Restart Timer has been lengthened to
allow the pattern generator to function. Once the
511/511E test is started, the Local unit changes
its' Restart Timer to one minute. The pattern
originates within the Processor and is sent to
the Remote unit. It is then looped back to the
Local unit where it is evaluated for errors. After
45 seconds, the Pattern Generator will timeout
and stops sending the pattern. The ER led will
begin blinking until the user turns off the
511/511E switch.

5.3.3 The V.52 (BER) Test Pattern Generator
To use the V.52 BER tests in conjunction with the Remote Digital
Loopback tests, follow these instructions:
1.
Locate the Remote Loop/511 & Remote Loop/511E toggle
switch on the front panel of the 1089 and move it DOWN.
This activates the Remote Loop with V.52 BER
and transmits a “511” test pattern into the loop. If any errors
are present, the local unit’s red “ER” LED will blink
sporadically.
