3.0 CONFIGURATION

This section describes the location and orientation of the Model
3088RC’s configuration switches and jumpers, and provides detailed
instructions for all possible settings. Each 3088RC model has different
configuration requirements, depending on the card’s serial interface.

You can configure the 3088RC using either the software (CLI via a
1001CC port) or the hardware (via DIP switches).

3.1 ABOUT SOFTWARE (CLI) CONFIGURATION

To use software configuration you must set DIP switches S1 and S2 to
the ON position, and set DIP Switch S3 to the management address,
before powering-up the RocketLink-G. When DIP switches S1 and S2
are set to ON, the RocketLink-G will operate in software-configuration
mode. When set for software-configuration mode the RocketLink-G will
read any configuration data previously saved to FLASH memory during
system power-up. If no configuration data was previously saved to
FLASH, then the RocketLin k-G wil l loa d th e fac tory -de fault configuration
from FLASH memory. After power-up, you may use console commands
or the Embedded O pe rati ons C h ann el (EO C) to modify the configurati on
parameters.

3.2 ABOUT HARWARE (DIP SWITCH) CONFIGURATION

To use DIP-switch configuration you must first set the DIP switches to a
position other than all OFF or all ON before powering-up the RocketLink­G. When all the DIP sw itches are set to any posi tion ot her than al l OFF or
all ON the RocketLink-G will ope rate in ha rdwa re (DIP-s witc h)-configura­tion mode. In DIP-switch-configuration mode the RocketLink-G will read
the DIP-switch setting s durin g sys tem st artup and co nfigure its elf accord­ing to the switch settings.

Once you power-up the RocketLink-G in DIP-switch mode it will operate
in DIP-switch mode until powered down. When operating in DIP-switch
mode you cannot change any configuration settings:

• Changing the DIP switch settings while the device is running will not
modify the operating configuration because the RocketLink-G only
reads the DIP switches during system startup.

• If you attempt to modify the configuration by issuing console com­mands, the device w ill n ot execut e yo ur comma nds. In stead , the R ock­etLink-G will respond with a message indicating the device is
operating in DIP-switch-configuration mode.

13

• If you attempt to modify any configuration p arameters via the EOC (by
changing (EOC variables), the RocketLink-G will not execute your
changes.

3.3 CONFIGURING THE DIP SWITCHES

(V.35, X.21, and Ethernet

Models)

The Model 3088RC is equipped with three sets of DIP switches, which
you can use to configure the RocketLink-G for a broad range of applica­tions. This section describes switch locations and discusses the configu­ration options available.

Note By default, the RocketLink-G’s DIP switches are all set to “ON”

so the NTU can be configured via the console. If that is how you
will be configuring the NTU, skip ahead to the section on config­uring the console.. Otherwise, read the following sections to
manually configure the DIP switch settings.

S2-2: Line Probe

Line probe is a mechanism that determines the highest rate (192K to
2304K) that the DSL link can reliably support. This takes place during
training. The DSL rate will be set to the rate that line probe determines.
Note that both the CO and CPE unit must have line probe enabled for it
to take effect.

Line probe could be us ed to d ete rmine the best rate the line will support,
and then the user could set the units for that rate and disable line probe
so that the rate won’t change without the user’s knowle dge .

X.21 modem must be set to either Internal or External/Network
clock mode.

— The X.21 modem that is configured as Receive-Recover must

be DCE.

3088RC uses the RX clock
from the DSL line as the
clock for the serial interface.

— The X.21 modem that is configured as Internal must als o b e

DCE, but if it is an External/Network clock, then the modem
must be configured as DTE.

S2-6: DTE Loops

The V.35 interface provides two pins, one to request an LAL and the
other to request an RDL. If DTE loops are enabled, the 3088RC/A/I will
start a local loopback or a remote loopback when these pins are
asserted. If DTE loops are disabled, these requests will be ignored.

ON Enabled
OFF Disabled

S2-7: DTE Interface Type

The DTE interface type needs to be se t based on the rear mo dule. Set to
E1 if using the /K model. Set to normal if using any other model.

S3-1 through S3-8: Management Address

Each rack card in a chassis must have a unique management address.
The 1001CC and 1001MC use this address to activate and deactivate
the rack card's management interface. This is necessary because all
rack cards in a chassis communicate over the same bus, so only one
card can be active at a time.

This address can be set to any value between 0 and 255. Set S3 to the
binary representation of the number (ON=0 and OFF=1). S3-8 is the
most significant bit.

3.4 ABOUT SYSTEM RESET MODE

To enter system reset mode, switch all DIP switches to the OFF position
and power cycle the unit. You can use a VT100 emulator configured for
19200 bps/1 stop bit/ no parity/ XON-XOFF flow control to access the
console. Upon restart, you will see the message “Reset Mode”. The
3088RC automatically communicates through the 1001CC in reset
mode, and does not wait for its address.

System reset mode provides two functions: software upgrades and con­figuration reset to factory defaults.

19

Software Upgrades

The software is u pgraded by waiting for the Reset Mode mes sage. The n,
the user can send an Intel HEX file supplied by Patton. After the VT100
emulator has finished sending this file, the 3088RC will respond with a
mes-sage stating how many errors were detected. The user may then
set the DIP switches to the desired configuration and power cycle the
unit to run the upgraded software.

Configuration Reset to Factory Defaults

To recover from a forgotten password, the user may reset the unit to its
factory configuration. After seeing the Reset Mode mess age, the user
should type the ‘*’ key. This will result in a ‘:’ prompt. At the prompt, the
user should enter th e comman d reset. This w ill res tore the unit to th e fac­tory configuration. The unit can then be restarted with the settings in
place.

3.5 CONFIGURING THROUGH THE CONSOLE

The 3088RC offers a console command line interface. To access the
console, use a VT100 emulator configured to 9600 bps, 1 stop bit, no
parity, and XON-XOFF flow control. Use the 1001CC to access the con­sole. Type CTRL+B <address> <enter> to activate the console. Log into
the unit using the default password. No username will be needed.

Note Log in with the default password superuser.

You can configure the following variables through the console:

• Password: The password used to login to the console.

• Circuit ID: The circuit ID communicated to other units via EOC. EOC
(Embedded Operations Channel) is an out-of-band channel specified
in the G.991.2 standard for SHDSL. We use standard EOC messages
for our remote loopback. The 3088RC also supports proprietary EOC
messages that allow a 3096RC to configure it.

• Clock Mode: The following options are available:

— Internal: The internal oscillator in the 3088RC provides the

clock to both the serial/T1/E1 and DSL interfaces.

— External: The serial interface provides the clock for the DSL

interface (V.35, X.21). It must be set to DTE for the X.21 inter­face. (This mode is invalid for the Ethernet model).

— Receive Recover: The 3088RC recovers the clock from the

DSL interface and provides it to the serial/E1 interface.

20

• Data Rate: Both the se rial/E1 an d DSL da ta rates are set by spec ifying
the number of 64k timeslots.

• Annex: Either G.991.2 Annex A or Annex B.

• DTE Interface Type: Either E1 or a normal serial interface.

• DSL Error Monitor Max Interval Errors: The number of errors
allowed in an interval before considering the interval errored. A value
of ‘0’ disab les the DSL error monitor.

• DSL Error Monitor Interval Time: The length in seconds of
an interval.

• DSL Error Monitor Interval Count: The numbe r of errored intervals
allowed before restarting the DSL link.

• DSL Error Monitor Total Intervals: The number of inte rvals to in spect
before disabling the error monitor.

• DSL Error Monitor Startup Delay: The length in second s to w ait afte r
the DSL link is established before starting the error monitor.

• Test Mode s: Loopbacks (LAL or RDL) and PRBS (pseudo-random
binary sequence) BER tests (511 or 511 with errors)

• Line Probe: Enable or disable Line Probe for rate
adaptive applications.

The following status information is available through the command
line interface:

• LEDs: Which software controlled LEDs are currently on.

• FPSW Settings: What the front p a nel swit ch es are set to (if the unit is
populated with them).

• Configuration Mode: Whether the 3088RC is configured by DIP
switches or softwar e.

• DSL Link State: In Progress, Success, Deactivated, or Idle.

• DSL Sync State: Out of Sync, Acquiring Sync, In Sync, or Losing
Sync.

Note DSL Link State vs. DSL Sync State—The DSL link state

describes whether the DSL is training (in progress), linked (suc­cess), deactivated (we don’t have an option to deactivate the
modem, so the user should not see this), or idle.

The DSL sync state describes whether no sync words have

21

been found (out of sync), there are no sync word errors (in
sync), or whether we are transitioning from out of sync to in sync
(acquiring sync) or vice versa (losing sync). Typically, when the
link is training, the sync state goes from out of sync to acquiring
sync to in sync.

• DSL Actual Rate: The actual rate at which the DSL link is running
(minus DSL overhead).

• DSL Line Condition: Good or Poor.

• Noise Margin Ratio: the maximum tolerable increase in external
noise power that still allows for BER of less than 1x 10–7.

• DSL Error Counters: The following error counters are available:

— CRC
— LOSW (Loss of Sync Word)
— TX FIFO Full
— TX FIFO Empty
— TX FIFO Slip
—TX Stuff
— RX FIFO Full
— RX FIFO Empty
— RX FIFO Slip

Console Help Commands

The following commands are provided to help the user find the
correct command:

• help: Lists all the commands that the console recognizes.

• system help: Lists all the commands that start with system that the
console recognizes.

• system set help: Lists all the commands that start with system set
that the console recognizes.

• system show help: Lists all the commands that start with system
show that the console recognizes.

22

• dsl help: Lists all the commands that start with dsl that the
console recognizes.

• dsl set help: Lists all the commands that start with dsl set that the
console recognizes.

• dsl show help: Lists all the commands that start with dsl show that
the console recognizes.

• dsl show errcntr help: Lists all the commands that start with dsl

show errcntr that the console recognizes.

System Configuration Commands

The following commands allow the user to configure the system:

• system set password <password>: Sets the sy ste m p as sword.

• system set circuitid <circuitid>: Sets the circuit ID.

• system set clockmode <internal|external|receiverecover>: Sets
the clock mode. Internal clock mode means the 3088RC provides the
clock to both the DSL and the serial interface. External clock mode
means the 3088RC uses the serial transmit clock as its DSL transmit
clock. Receive recover clock mode means that the 3088RC uses the
DSL receive clock as its DSL transmit clock and as the serial receive
clock.

Note X.21 External Clock Mode—The X.21 interface expects the

DCE to provide the clock used for both transmitting data and for
sampling receive data. When the 3088RC/D/V is set as a DCE,
it may be used in internal or receive recover clock modes. The
DSL generates a clock that is provided to the X.21 interface.

When the 3088RC/D/V is a DTE, it may be used in external
clock mode. The X.21 interface needs to provide the clock. This
clock is used by the DSL to sample the serial data and also to
update the receive data.

The 3088RC is set for either DCE or DTE by flipping the daugh­ter-card. The 3088RC is a DCE if DCE points toward the front of
the 3088RC.

• system set dteif <normal|e1>: Set to E1 if the rear card is Model
3088RC/K/K. Set to normal for all other models.

• system set fpsw <enabled|disabled>: Enable or disable initiating
test modes using the front panel switches.

23

The following commands allow the user to view the current
system configuration:

• system show config: Shows the configuration of the entire system,
including DSL and serial/T1/E1 lines.

Any changes to the system con figuration or the DSL configur ation will be
lost on the next power cycle unless the changes are saved. The com­mand system save config is used to save the changes.

System Status Commands

The following commands show system status:

• system show status: Shows the following system status information:
LEDs, DSL test mode, front panel switch settings, DSL link state, and
configuration mode.

DSL Configuration Commands

The following commands are used to configure the DSL:

• dsl set timeslots <1–72>: Sets the number of timeslots. The data rate
is calculated by the equation: data-rate = #timeslots x 64k.

• dsl set annex <a|b>: Set the annex.

• dsl set lineprobe <enabled|disabled>: Enable or disable line probe.

• dsl set link <enabled|disabled>: Enable or disable the DSL port.
When disabled, a DSL link cannot be established.

• dsl set loopback <off|lal|rdl>: Start or stop loopbacks.

• dsl set pattern <off|511|511e>: Start or stop PRBS generator and
BER meter.

• DSL Error Monitor

The DSL error monitor ins pects inte rvals to s ee if they have met the e rror
threshold (maxint). If the error monitor finds a certain number (intcnt) of
intervals that meet or exceed the error threshold, it will restart the DSL
link. The error monitor will wait (startdelay) seconds after the DSL link
comes up before it begi ns monitorin g errors. Af ter the st artup delay, it will

check the number of errors that have occurr ed during each (inttime) sec­onds to see if they meet the error threshold. The error monitor inspects
(totint) intervals before it stops.

Note Setting maxint to 0 disables the error monitor and setting totint

to 0 causes the error monitor to run continuously.

The following commands configure the error monitor:

• dsl set errmon maxint <maxint>: Sets the number of errors allowed
in an interval causes it to be considered an errored interval. If this is
set to ‘0’, then the error monitor is disabled.

• dsl set errmon inttime <inttime>: Sets the length of each interval.

• dsl set errmon intcnt <intcnt>: Sets the number of errored intervals
that causes the DSL link to restart.

• dsl set errmon totint <totint>: Sets the nu mber of interv als to inspe ct
for errors before disabli ng the er ror moni tor. If this is set to ‘0’, then th e
error monitor will run continuously.

• dsl set errmon startdelay <startdelay>: Sets the number of seconds
to wait after the DSL link comes up before the error monitor starts
inspecting intervals.

Changing the dat a ra te ( dsl set timeslots), the clock mode (system set

clockmode), the Annex (dsl set annex), or Line Probe (dsl set
lineprobe), or the DSL error monitor settings will not take effect on the

DSL link until the link restarts. The dsl start command restarts the
DSL link.

DSL Status Command

The dsl show status command shows the following DSL status informa-
tion: link st ate, s ync st ate, link spe ed, e rror count ers, line condit ion, noise
margin, and test mode status.

DSL Clear Errcntrs Command

The dsl clear errcntrs command clears the error counters.

3.8 CONFIGURING THE E1 REAR CARD

The E1 rear card features config uration cap abilit y vi a hardware swi tch es
and jumpers. Section s 4. 1 and 4.2 describe all switch and jump er co nfi g­urations for the 3088RC/K model. Section 4.3 describes the configura­tion required for your mDSL modem.

DIP Switch Configuration

The E1 card has eight internal DIP switches (S1-1 through S1-8). The
DIP switches can be configured as either “On” or “Off.”

Switch S1-1 : Line Coding. Use Switch S1-1 to control the Network
Line Coding options. Set these options to be the same as the Line Cod­ing that has been provided by your Service Provider.

S1-1 Line Framing & Coding

Off HDB3
On AMI

Line Coding Options:

• High Density Bipolar 3 (HDB3): In HDB3 coding, the transmitter
deliberately inserts a bipolar violation when excessive zeros in the
data stream are dete ct ed. Th e rec ei ver recognizes these special viola­tions and decode s them as zeros . Th is me thod en ables the net work to
meet minimum pulse density requirements. Use HDB3 unless AMI is
required in your application .

28

• Alternate Mark Inversion (AMI): AMI coding does not inherently
account for ones density. To meet this requirement, you should ensure
that the data inherently meets pulse density requirements.

Switch S1-2 : CRC-4 Multiframe. CRC-4 Multiframe uses Time Slot
zero to carry CRC-4 information. When CRC-4 is enabled (ON), the unit
synchronizes to the CRC-4 multi-frame protocol.

S1-2 Option

Off On
Disabled Enabled

Note When the data rate is set to 2048 Kbps, K Module transmits

user data on all 32 timeslots, ignoring framing information. In
this case, Switch S1-2 will be ignored.

Switch S1-3 : Clear Channel Mode. When S1-3 is at Off position, the
K Module is running in G.703 clear channel mode. When S1-3 is at On
position, the K Module is running in G.704 framed mode. When the K
Module is set to framed mode, channel 0 will be used to pass G.704
framing information which results in a maximum bandwidth of 1984kbps
for user data.

S1-3 Option

Off On
Clear Channel Mode (G.703) Framed Mode

(G.704)

Switch S1-4 Through S1-8 : Reserved. Reserved for future use and
should be set to OFF.

Jumper Configuration

The 3088RC/K model has fo ur jumpers (two position headers): JP4, JP5,
JP6, and JP7. These jumpers are used to selec t inp ut and output imped­ance matching between the module and external line. See Appendix E
for jumper locations.

The following is a description of the jumper settings with respect to the
front panel connectors.

1. For a 75 ohm connection (coax) install JP4 - JP7 (default).

2. For a 120 ohm connection (RJ-48C) remove JP4 - JP7.

29

Making Interface Connections

The 3088RC/K model may be connected to G.703/G.704 ports using a
single 120 ohm RJ-48C or a dual 75 ohm coax (BNC). The 3088RC/K
model rear panels and the location of these connectors are show below.

Figure 4. K Module Rear Panels, Showing Location of Connectors

Connect Twisted Pair (120 ohm) to G.703/G.704 Network . The

3088RC/K model is equipped with a single RJ-48C jack for connections
to a 120 ohm twisted pair G.703/G.704 network interface. If your G.703/
G.704 network terminates via RJ-48C, use the dia gram belo w and the
table on the following page to make the proper connections. The con­nector pinout and signals are shown in Figure 5.

Use the following connection diagram to connect the 120 ohm G.703/
G.704 network channel.

Connect Dual Coaxial Cable (75 ohm) to G.703/G.704 Network. The
3088RC/K model is also equipped with dual female BNCs (TX and RX)
for connection to a 75 ohm dual coax G.703/G.704 network interface. If
your G.703/G.704 network terminates via dual coaxial cable, use the dia­gram below to make the proper connections. The connector pinout and
signals are shown in Figure 6.

3.9 CONNECTING THE ETHERNET REAR CARD

The Model 3088RC/C/AI module plugs into Patton’s1092ARC and
3088RC modems t o provide Et hern et LAN ex tensio n. The 3 088 RC/C/AI
has no switches or jumpers and does not need to be configured. How­ever , fac tors such as the type of medium, throu ghp ut a cro ss the l in k an d
clocking mode must be determined by the settings of the baseband
modems. Please ref er to your b aseband modem (i .e. 1092, a nd 1095) t o
make the following settings.

1. Bit Rate: The DTE rate setti ng of y our base un it corr esp onds to the

throughput of your 3088RC/C/AI bridge module. Use higher speeds
to allow maximum throughput to your extended LAN. Use lower
speeds to limit the access of your extended LAN.

Note The 3088RC/C/AI only supports synchronous speeds.

2. Clocking Mode: Set the clocking modes on the base units so that

one unit is conf igured for Internal c locking mode and the other u nit is
set for Receive Recover clocking mode.

3. When using the 3088RC/C/AI, DISABLE, the “Enable Loop from

DTE” Switch on the front function card (1092ARC or 3088RC).

4. All othe r base unit setti ngs d epend upon your applic ation and on the

application medium (twisted pair or coaxial cable)

32

Connecting the Interface Driver Board

This package co nta ins an int erface driver board tha t allows you to confi g­ure your front function card for ethernet operation. Figure 7 shows the
Interface Driver Board connected to a Model 3088RC front function card.

Figure 7. Driver Board mounted on Model 3088RC

Follow the instruction s be low to connect the interface driver board to the
front function card:

1. With the function card (such as 3088RC, shown abov e) pulled o ut of

the NetLink rack or clusterb ox chass is, locate the dri ve r board to be
replaced on the top of the base unit front card.

2. Lift the old interface board gently off of the printed circuit board.

3. Position the 3088RC/C/AI driver board on top of the function card’s

pc board with the sockets oriented toward the male pins. Please be
sure the label marked FRONT is pointed toward the front of the
function card (toward the LEDs).

4. Push the Interface Driver B oard g ently onto the socket and re -ins t a ll

the function card into the rack or cluster system.

33

Connecting to the 10Base-T Ethernet Port

The Model 3088RC/C/AI provides line side connections through a termi­nal block or through a RJ-45 connector. Figure 8 below, shows the rear
panel options and the locations of the connectors.

Figure 8. 3088RC/C/AI Ethernet Port

The RJ-45 Ethernet port on Model 3088RC/C/AI is designed to connect
directly to a 10BaseT network. Figure 9 shows the 10BaseT RJ-45 port
pin description. You may make conn ec tion s up to 330 feet using Type 4
or 5 cable.

Figure 9. Model 3088RC Ethernet Connector Pinout

34

Connecting the 10Base-T Ethernet Port to a Hub . The Model
3088RC/C/AI 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 di agra m b elo w to c onstruc t a c ab le to connect the
3088RC/C/AI to a 10Base-T Hub.

Connecting the 10Base-T Ethernet Port to a PC (DTE). The Model
3088RC/C/AI 10Base-T interface is configured as DTE (Data Terminal
Equipment). If you wish to connect the 3088RC/C/AI to another DTE
device such as a 10Base-T network interface card in a PC, you must
construct a 10Base-T crossover cable as shown in the diagram below.

Connecting the Line Interface. The Model 3088RC/C/AI is to be used
with Patton function card access products (i.e. 1092ARC) There are two
essential requirements for conn ecting the line interface on Model
3088RC/C/AI:

1. These units work in pairs with one 3088RC/C/AI connected to

another 3088RC/C/AI (or IM1/I) over 2 or 4-Wire Twisted pair (2 or
4-Wire operation is determined by the front function card).

2. To function properly, the Model 3088RC/C/AI needs one or two

twisted pairs of metallic wire (two or four wire). The twisted pairs
must be unconditioned, dry, metallic wire, between 19 (.9mm) and
26 AWG (.4mm) (Ap pendix B desc ribes cabl e require ment s) . Stan­dard dial-up telephone circuits, or leased circuits that run through

35

signal equalization equipment, or standard, flat modular telephone
type cable, are not acceptable.

Figure 10. RJ-45 Line Interface

Note Two-Wire Modems use RJ-45 pins 4 and 5 and 4-Wire Modems

use RJ-45 pins 3, 4, 5 and 6, as shown above. Please see the
Function Card User Manual for more details.

LED Status Monitors

The Model 3088RC/C/AI fea tures two LEDs that moni tor general oper at­ing status and the 10Base-T twisted pair link integrity. Figure11 shows
the LEDs located directly beneath the RJ-45 jack.

Figure 11. 3088RC Rear Panel, LED Locations

Status. Blinks yellow from one to eleven tim es to indicate syste m 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 ar e:

• 1 pulse = system status ok

• 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 = IMRC2/IA buffer is saturated

• 5 pulses = WAN receive frame(s) too large

• 6 pulses = WAN receive frame(s) not Octet aligned

• 7 pulses = WAN receive frame(s) aborted

• 8 pulses = Detected WAN receive frame(s) with bad CRC

• 9 pulses = Detected LAN receive frame(s) too large

• 10 pulses = Detected LAN receive frame(s) not Octet aligned

• 11 pulses = Detected LAN receive frame(s) with bad CRC

After a status code is displayed eight times and the a ssoc iate d c ond ition
is removed, the status code will no longer appear.

Link. Glows green to indicate good link integrity on the 10Base-T
twisted pair line.

3.10 CONNECTING THE 10/100 ETHERNET REAR CARD

The Model 3088RC/C/AI-100B module plugs into Patton’s 3088RC
modem to provide Etherne t LAN extensi on. The 3088 RC/C/AI-100B ha s
a jumper that needs to be conf igured . The jumper at J 7 should be fa ctory
installed on pins 1 and 2. Factors such as the type of medium, through­put across the link and clocking mode must be determined by the set­tings of the 3088 standalone modem. Please refer to your 3088
standalone modem to make the following settings.

1. Bit Rate: The DTE rate setti ng of y our base un it corr esp onds to the

throughput of your 3088RC/C/AI-100B bridge module. Use higher
speeds to allow maximum throughput to your extended LAN. Use
lower speeds to limit the access of your extended LAN.

Note The 3088RC/C/AI-100B only supports synchronous speeds.

2. Clocking Mode: Set the clocking modes on the base units so that

one unit is conf igured for Internal c locking mode and the other u nit is
set for Receive Recover clocking mode.

3. When using the 3088RC/C/AI-100B, DISABLE, the “Enable Loop

from DTE” Switch on the front function card.

4. All othe r base unit setti ngs d epend upon your applic ation and on the

application medium (twisted pair).

Connecting the 10/100BaseTX Ethernet Port to a Hub. The Model
3088RC/C/AI-100B 10/100BaseTX interface is auto-sensing, meaning
that it can connect to either a 10/100BaseTX switch, hub or a PC. Use a
straight-through or cross-over cable to connect the 10/100BaseTX port.
Refer to the wiring diagram below.

Connecting the Line Interface. The Model 3088RC/C/AI-100B is to be
used with Patton function card access products.There are two essential
requirements for connecting the line interface on Model 3088RC/C/AI­100B:

1. These units work in pairs w i th o ne 3 088 R C/ C/AI-10 0B c onn ec ted to

another 3088RC/C/AI-100B (or 3088/I standalone modem) over 2­wire twisted pair.

2. To function properly, the Model 3088RC/C/AI-100B needs one

twisted pair of metallic wire (two wire). The twisted pairs must be
unconditioned, dry, metallic wire, betwe en 19 (.9m m) and 26 AWG
(.4mm) (Appendix B describes cable requirements). Standard dial­up telephone circuits, or leased circuits that run through signal
equalization equipment, or standard, flat modular telephone type
cable, are not acceptab le.

4.0 INSTALLATION

This section desc ribes the func tions of the Mo del 100 1R14 rack ch assi s,
tells how to install front and rear Model 3088RC Series cards into the
chassis, and how to connect to the twisted pair interface and the serial
interface.

4.1 THE MODEL 1001R14 RACK CHASSIS

The Model 1001R14 Rack Chassis (Figure 17) has fourteen short range
modem card slots, plus its own power supply. Measuring only 3.5” high,
the Model 1001R14 is designed to occupy only 2U in a 19” rack. Sturdy
front handles allow the Model 1001R14 to be extracted and transported
conveniently.

Figure 17. Model 1001R14 Rack Chassis with power supply

The Rack Power Supply

The power supply included in the Model 1001R14 rack uses the same
mid-plane architecture as the mod em cards . The front card of the power
supply slides in from the front, and the rear card slides in from the rear.
They plug into one another in the middle of the rack. The front card is
then secured by thumb screws and the rear card by conventional metal
screws.

There are no user-serviceable parts in the power supply
section of the Model 3088RC Series. Voltage setting
changes and fuse replacement should only be per-

Powering Up Your 1001R14 Rack

Note The power supplies that come with your 1001R14 rack system

are equipped with a power entry connector on the rear card. The
power supplies are Hot-Swappable, so you are not required to
remove the cards from the rack while applying power to the sys­tem.

When a power cable is connected between the unit, and an appropriate
power source, a green LED on the front panel will glow to indicate that
the unit is working properly. Since the Model 1001R14 is a "hot swappa­ble" rack, it is not necessa ry for any ca rds to be inst al led befo re apply ing
power. The power may be removed at any time withou t harming the
installed car ds.

Note Please refer to the Model 1001RP14 Series User Manual AC &

DC Rack Mount Power Supplies for fuse and power card

replacement information.

4.2 INSTALLING MODEL 3088RC SERIES INTO THE CHASSIS

The Model 3088RC Series is comprised of a front card and a rear card.
The two cards meet inside the rack chassis and plug into each other by
way of mating 50 pin card edge connec tors. Us e the foll owin g step s as a
guideline for installing each Model 3088RC Series into the rack chassis:

1. Slide the rear card into the back of the chassis along the metal rails

provided.

2. Secure the rear card using the metal screws provided.

3. Slide the front card into the front of the chassis. It should meet the

rear card when it’s almost all the way into the chassis.

4. Push the front card gently into the card-edge receptacle of the rear

card. It should “click” into place.

5. Secure the front card using the thumb screws.

4.3 CONNECTING THE TWISTED PAIR INTERFACE

The Model 3088RC supports communication between two DTE devices
as follows:

The interconnecting cables shall be acceptable for
external use and shall be rated for the proper applica-

CAUTION

Using 24 AWG (0.5 mm) wire up to:

• 32,000 feet (9.7 km) at 192 kbps

• 18,500 feet (5.6 km) at 2.312 Mbps

Using 26 AWG (0.4 mm) wire up to:

• 23,000 feet (7 km) at 192 kbps

• 13,200 feet (4 km) at 2.312 Mbps

Two things are essential:

1. These units work in pairs. Both units at the end of the twisted pair

DSL span must be set for the same DTE rate—one unit set as CO,
the other as CP.

tion with respect to voltage, current, anticipated tem­perature, flammability, and mechanical serviceability.

2. To function properly, the Model 3088RC needs one twisted pair of

metallic wire. This twisted pair must be unconditioned, dry, metallic
wire, between 19 (0.9mm) and 26 A WG (0.4mm) (the high er number
gauges will limit distance). Standard dial-up telephone circuits, or
leased circuits that run through signal equalization equipment, or
standard, flat modular telephone type cable, are not acceptable.

Connecting the Model 3088RC/A/I (V.35) to a “DCE” device

The Model 3088RC/A/I provides a V.35 DCE (data circuit terminating
equipment) interface on a M/34 connector. As a DCE, this interface is
designed to connect to DTE equipment, such as a router. However, con­necting the 3088RC/A/I to another DCE device, such as a multiplexer or
G.703 E1 NTU, requires a tailcircuit cable. When connecting the V.35
interface of the Model 3088RC/A/I to your DCE device, use a V.35 tail
circuit cable. Some ap plications may also require the inst allation of a tail­circuit buffer to ac cou nt fo r sm al l differences in clock frequency betw e en
the 3088RC/A/I and the V.35 DCE (multiplexer).

4.6 CONNECTING THE 3088RC/K/K (E1) INTERFACE

The Model 3088RC/K/K is a rear-mountable G.703/G.704 interface card
that works with the Patton Model 3088RC function card. The two cards
meet inside the rack chassis and plug into each other by way of mating
50 pin card edge connectors. Use the following steps as a guideline for
installing each Model 3088RC/K/K and its function card mate into the
rack chassis:

1. Slide the rear card into the back of the chassis along the metal rails

provided.

2. Secure the rear card using the metal screws provided.

3. Slide the front card into the front of the chassis. It should meet the

rear card when it’s almost all the way into the chassis.

5.0 OPERATION

Once the Model 3088RC is properly configured and installed, it should
operate transparently. These sections describes functions of the LED
status indicators, and the use of the built-in loopback test modes.

5.1 LED STATUS INDICATORS

The Model 3088RC features four front panel LEDs that monitor the opera­tion of the rack card. Figure 22 shows the front panel location of each LED.
Table 1 describes each LED’s function.

5.2 TEST MODES

The 3088RC offers test modes in the form of loopbacks, PRBS pattern
generators, and combinations of both (see Figure 22 on page51).

Loopbacks

The 3088RC supports both Local Analog Loopbacks (LAL) and Remote
Digital Loopbacks (RDL). These can be initiated either from the optional
front panel sw itches or by the consol e command dsl set loopback
<off|lal|rdl>. The data path for the LAL is shown in Fi gure 24.

The data received from the serial interface is looped back before going
out on the DSL line. Note that this loopback occurs after the pattern gen­erator/BER meter. This means that running a 511 pattern in conjunction
with an LAL should result in no error detected by the meter. The data
path for the RDL is shown in Figure 25.

The RDL causes the remote unit to loop the data received from the DSL

Patterns

The 3088RC can generate and detect 511 and 511 with Error patterns.
These can be initiated either by the optional front panel switches or by
the console command dsl set pattern <off|511|511e>. When the pattern
is started, the DSL framer uses its internal 511 pattern generator for its
DSL TX data instead of the data received from the serial interface. Also,
the framer’s internal BER Meter tries to detect a 511 pattern in the DSL
RX Data.

Because the BER Meter always runs when the pattern generator runs,
the meter will detect errors if either the pattern is not either looped back
or the remote unit is not transmitting a 511 pattern.

One point to note is that the wa y errors a re generate d in the 5 11E pattern
generates CRC errors. This can cause the DSL error monitor to restart
the link if the thresholds are set low enough.

5.3 REMOTE CONSOLE OPERATION

The PC user (near-end) may configure and verify status of the remote
3088RC (far-end) via a Remote Console session. The PC user must log
onto the 3088RC (near-end) unit to establish a remote console session.
Once done, the remote 3088RC (far-end) appears as a unit which is
locally connected through the RS-232 console port. All commands are
transmitted over the G.SHDSL link in the EOC channel.

Establishing a Remote Console Session

How to Connect . The following steps are to establish a connection to

the remote 3088RC (far-end) via Remote Console Session (RCS):

1. Configure a te rmina l emula tion prog ram ( e.g., Hy perterm inal) on P C
(near-end) for 9600 bps, 8 data bits, no parity, 1 stop bit, no flow
control. Connect it to the 1001CC in the same chassis as the
3088RC (near-end).

2. At the password prompt, log in to the near-end Model 3088RC.

53

3. Ensure that a DSL link is established. You can verify an established
DSL link by using the system show status command or by checking
that the DSL LED is solid green. Upon executing the show status
command, the dsl link state is shown as success if the DSL link is
established.

4. At the command prompt, enter the command remote console.

5. Wait for the message Console: Remote console connection estab-
lished.

— If a DSL link is not established, or for some other reason the

3088RC (far-end) does not respond in a reasonable amount of
time, the follow ing message appears: Co nsole: Remote console
timed out trying to con-nect. Enter the command remote con­sole again.

— If 3088RC (Far End) already has an active remote console ses-

sion open, you will see the message Console: Remote console
connection request rejected. This can also happen if the re mote
3088RC (far-end) has an established remote console session
with the local 3088RC (near-end) which has timed out.

6. Enter the password at the password prompt for the remote console
session.

Note The passwords for a local console session of the 3088RC (near-

end) and the remote console session of the 3088RC (far-end)
should be different for the purpose of security.

7. You s hou ld now b e l ogg ed into the remote 3088RC (far-end) via th e
remote console session. The communication with the remote
3088RC (far-end) is essentially the same as having a local console
connection.

Note The local or remote 3088RC may be CO or CPE, as long as

there is one of each. Either the CO or CPE unit may accept a
remote console connection.

Note With a remote console session open, a user at PC (far-end) is

blocked from using the local console. Upon typing anything, the
3088RC (far-end) sends a message to the PC (far-end) stating
Console: Remote console connection is open.

54

Figure 27 is a screenshot of opening a typical remote console session:

We can now enter commands on
the remote console

Figure 27. Opening a typical remote console session

How to Disconnect . The remote console session ends under any of

the following conditions:

• The user enters the command logout

• A timeout period of 5 minutes elapses since the user has entered a

command to the console.

• The DSL link drops.

The response upon logging out of the remote console session with the
command logout is Console: Remote console connection lost. The fol­lowing is what is displ ayed upon a user’s logging out of a remote console
session after logging in.

> remote console
>
Console: Remote console connection established.

password: ******
> logout
Console: Remote console connection lost.

55

>

The timeout period is a fixed , non-confi gurable p aramete r of 5 mi nutes. If
the remote 3088RC (far-end) has received no command within 5 min­utes, it automatically terminates the RCS. Once the RCS is terminated,
the PC (far-end) can establish a local console session if desired. How­ever if the PC (near-end) wishes to re-es tab lish a RCS, it i s able to do so
whether or not the PC (far-end) is in an active local session, bec ause the
RCS has priority over a local console session. If the PC (near-end)
establishes an RCS while the PC (far-end) is on a local session, the PC
(far-end) is kicked off.

Differences in Local and Remote Control Session Behavior

Since the remote console session communication occurs over the
G.SHDSL link’s EOC channel, some commands via the RCS have
unusual effects.

• system upgrade: Do not issue this command via an RCS. A system

upgrade must be done via the local console connection. If you should
accidentally issue this command over an RCS, the remote 3088RC
(far-end) waits indefinitely for input (which is the system upgrade
image) from the local cons ole port of the 3 088R C (far-end). If this com­mand is entered, 3088RC (Far End) will have to be power-cycled.

5.4 SOFTWARE UPGRADE

The Model 3088RC is software upgradeable through the console port.
Software images will be available in Intel Hex file format.

The software upgrade feature is available either by powering up the
Model 3088RC with all DIP switches set to th e OFF position, or by enter-
ing the system upgrade command on the command line interface. The
software upgrade takes approximately 5 minutes to complete. The
3088RC will print ‘.’ to the screen while the software upgrade is in pro­cess. When the software upgrade completes, it will print a message stat­ing that it is complete and the number of errors, if any, that occurred.

Errors may occur during the sof tw are upg rade if t he ima ge is corru pt or if
there is a disruption in the console port connection. The Model 3088RC
will print a message to the co nsole port if it encounters any errors. In the
event of an error, the portions of the old image may have been overwrit­ten, and the unit may not be able to boot into operational mode. How­ever , th e u nit may still boot into the software upgrade, so a new so ftware
image can still be loaded to bring the unit back to an operational state.

to communicate with the far-end 3088RC.

Here is the software upgrade procedure:

1. Remove all cards from the rack except for th e card that y ou inten d to
upgrade.

2. Obtain the software image Hex file for the 3088RC.

3. Turn off the Model 3088RC.

4. Make a note of the current DIP switch settings, then set all DIP
switches to the OFF position.

5. Turn on the Model 3088RC.

6. Configure HyperTerminal for 19200 bps, 8 bits, 1 stop bit, no parity,
XON-XOFF.

57

7. Open Model 3088RC Console (v ia HyperTerminal or other terminal
emulation program).

>>Transfer
>>Send Text File...
>>Set “Files of Type:” to “All files (*.*)”
>>Select 033252Z.hex

8. When the transfer completes, turn off the Model 3088RC.

9. Set the DIP switches for the proper configuration.

10.Turn on the Model 3088RC. It now operates with the upgraded soft­ware.

5.5 RESET CONFIGURATION TO FACTORY DEFAULT

The configuration can be reset to factor y default s from the sof tware reset
mode. This allows a user to recover from a forgotten password. To reset
to the configuration, follow these steps:

1. Power down the unit.

2. Set all DIP switches to the OFF position.

3. Connect a PC to the Console port.

4. Open a VT100 terminal emulator (such as HyperTerminal). Config­ure the emulator for 19200 bps,1 stop bit, no parity, X-ON X-OFF
flow control.

Note The 3088RC will not wait for its address to be selected when in

software reset mode. It will automatically accept data from the
1001CC.

5. Power up the unit. The terminal should display the following mes­sage: Reset Mode.

6. Type the ‘*’ key. You will see a ‘:’ prompt.

7. Type the command reset.

8. When the command completes, the unit has been reset to factory
configuration.

9. Set the DIP switches to the desired configuration. Power cycle the
unit to begin using the new configurat ion .

A.5 DIAGNOSTICS

V.52 compliant (511/511E) pattern generator and detector with error
injection mode controlled by front-panel switch. Local and Remote Loop­back control either by a front-panel switch or from the DTE interface.

A.6 STATUS LEDS

• Power (Green): The Power LED glows solid during normal operation.

At startup, during the POST, the LED blinks once every second.

• DSL (Green): The DSL LED glows solid when a DSL link is estab-

lished. While the DSL link is training, it blinks once every second.

• Term (Yellow): The Term LED glows solid when a serial port is active.

• TM/ER (Green): The Test Mode/Error (TM/ ER) LED is used to indic ate

that a test mode is in progress or an error has been detected. It blinks
once every second while a test mode is starting. It glows solid while a

59

test mode is in progress. It blinks once if an error is detected either
during a test mode, or in normal DSL operation.
