1.1 RADIO AND TV INTERFERENCE

The Model 1089 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 tele-

vision reception. The Model 1089 has been tested and found to com-

ply 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 interfer-

ence will not occur in a particular installation. If the Model 1089 does

cause interference to radio or television reception, which can be deter-

mined by disconnecting the unit, the user is encouraged to try to cor-

rect the interference by one or more of the following measures: mov-

ing the computing equipment away from the receiver, re-orienting the

receiving antenna and/or plugging the receiving equipment into a dif-

ferent AC outlet (such that the computing equipment and receiver are

on different branches).

2.2 DESCRIPTION

The

NetLink

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

NetLink

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

NetLink

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.

NOTE: Packages received without an RMA number will not be

accepted.

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.

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).

The two sets of DIP switches on the underside of the Model 1089

will be referred to in this manual as S2 and S3. As Figure 2 shows,

the orientation of all DIP switches is the same with respect to “ON” and

“OFF” positions.

Figure 2. Close Up of Configuration Switches (all sets are identical in appearance)

3.1.1 Configuration DIP Switch Set “S2”

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.

Switch S2-1, S2-2, S2-3, S2-4, S2-5 and S2-8:

Switches S2-1, S2-2, S2-3, S2-4, S2-5 and S2-8 are reserved for fac-

tory use and must remain in the factory default settings as shown in

the table above. .

Switches S2-6 and S2-7: Clock Mode

Use Switches S2-6 and S2-7 to configure internal, or receive

recover (clocking derived from the remote Model 1089 across the DSL

span) settings. One Model 1089 (typically the CO, or “Central Office”

unit) will be set for Internal Clock. The remote Model 1089 (typically

the CP, or Customer Premises unit) will be set for Receive Recover

clocking. The table below shows the clock mode settings.

3.1.2 Configuration Switch Set “S3”

Use the DIP Switches in Switch S3 to set the DTE Rate (for LAN

Bandwidth Allocation), the transmit data sampling point and to reset

the unit to its software default settings. The following table summa-

rizes default positions of DIP Switch S3. Detailed descriptions of each

switch follow the table.

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.

Set Switches 3-1 through S3-6 to allocate bandwidth based upon

expected LAN to LAN traffic rates. As an example, set applications

which low LAN to LAN bandwidth content between 64kbps and

576kbps. Applications with high bandwidth LAN to LAN content should

be set between 576kbps and 2.304Mbps as required.

IINNSSTTAALLLLAATTIIOONN

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.

4.1 CONNECTING THE DSL INTERFACE

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:

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!

The RJ-45 connector on the Model 1089’s twisted pair interface is

polarity insensitive and is wired for a two-wire interface. The signal/pin

relationships are shown in Figure 4 below.

4.2 Connecting the 10Base-T Ethernet Port to a PC (DTE)

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.

4.3 Connecting the 10Base-T Ethernet Port to a Hub

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.

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.

4.4 POWER CONNECTION

Universal AC Power (100-240VAC)

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.

The Model 1089 powers up as soon as it is plugged into an AC

outlet--there is no power switch.

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.

DC Power

The 36-60 VDC DC to DC adapter supplied with the DC version of

the Model 1089 plugs in a DC source (nominal 48VDC) and plugs into

the barrel power supply jack on the rear of the 1089/I. Please refer to

Figure 5, below, to make the proper connection.

OOPPEERRAATTIIOONN

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.

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 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.

DSL Link (Active Green) Solid green (On) indicates that the

end to end DSL Framer Link is up, signifying that

the link across the DSL span is active. The DSL

Link LED is Off when the link is down.

Status Blinks yellow from one to eleven times to indicate

system status. Each pulse pattern is separated by

a 2 second “off” period. Greater pulse patterns

have higher priority (buffer saturation has greater

priority than an empty MAC table). Valid system

statuses are:

1 pulse = system status is okay

2 pulses = no MAC entries in the MAC

Address Table

3 pulses = Clear to Send (CTS) or Carrier

Detect (DCD) from base unit are not

asserted

4 pulses = IM1/I buffer is saturated

5 pulses = WAN receive frame(s) too large

6 pulses = WAN receive frame(s) not octet

aligned

WARNING! There are no user-serviceable parts in the

power supply section of the Model 1089. Contact Patton

Signal Processors (DSPs) are not linked.

ER (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.

- ER flashes once to indicate a CRC error (during

normal operation) or bit errors (during Remote

Loopback 511/511E tests).

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.

5.3 TEST MODES

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

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.

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

(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.

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.

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.

5.3.2 Loops and Patterns

The following section describes the Remote Loopback/BER test

modes.

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.

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.
