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!

IMPORTANT!: The Model 1089 has been optimized for per-  
formance at high bitrates (DTE rates greater than 512 kbps). To  
ensure accurate performance at these bit rates, please use twisted  
pair line interface cable that is at least 330ft (100m) in length.

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.  
NS  
ER  
(Active Red) Solid red indicates that the Digital  
Signal Processors (DSPs) are not linked.  
(Active Red) Flashing red indicates CRC Errors on  
DSL (Framer) side if DSL Link is active or if bit  
errors are received during loop/BER test.

Processor  
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.

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.
