2.2 DESCRIPTION  
The Patton Electronics Model 3088RC G.SHDSL RocketLink provides  
high speed 2-wire connectivity to ISPs, PTTs, and enterprise environ-  
ments using Symmetrical High-data-rate Digital Subscriber Line  
(G.SHDSL) technology.  
As a symmetric DSL NTU, RocketLink DSL offers the same data rates in  
both directions over a single pair of regular twisted pair lines using TC-  
PAM modulation. Line connection is made with an RJ-45 jack.The Model  
3088RC is designed to Þt into Patton’s 2U (3.5”) high rack chassis. This  
chassis uses a mid-plane architecture which allows front cards to be  
plugged into different rear cards. For more information, refer to the Model  
1001RP14 Manual for more information on the power supply options that  
are available.  
The NTU features externally-accessible DIP switches, loopback diagnos-  
tics, SNMP/HTTP remote-management capabilities using RocketLink  
Plug ‘n’ Play, as well as in-band management.

3.0 CONFIGURATION  
This section describes the location and orientation of the Model  
3088RC’s conÞguration switches and jumpers, and provides detailed  
instructions for all possible settings. Each 3088RC model has different  
conÞguration requirements, depending on the card’s serial interface.  
You can conÞgure 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 conÞguration 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-conÞguration  
mode. When set for software-conÞguration mode the RocketLink-G will  
read any conÞguration data previously saved to FLASH memory during  
system power-up. If no conÞguration data was previously saved to  
FLASH, then the RocketLink-G will load the factory-default conÞguration  
from FLASH memory. After power-up, you may use console commands  
or the Embedded Operations Channel (EOC) to modify the conÞguration  
parameters.  
3.2 ABOUT HARWARE (DIP SWITCH) CONFIGURATION  
To use DIP-switch conÞguration you must Þrst set the DIP switches to a  
position other than all OFF or all ON before powering-up the RocketLink-  
G. When all the DIP switches are set to any position other than all OFF  
or all ON the RocketLink-G will operate in hardware (DIP-switch)-conÞg-  
uration mode. In DIP-switch-conÞguration mode the RocketLink-G will  
read the DIP-switch settings during system startup and conÞgure itself  
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 conÞguration settings:  
• Changing the DIP switch settings while the device is running will not  
modify the operating conÞguration because the RocketLink-G only  
reads the DIP switches during system startup.  
• If you attempt to modify the conÞguration by issuing console com-  
mands, the device will not execute your commands. Instead, the Rock-  
etLink-G will respond with a message indicating the device is  
operating in DIP-switch-conÞguration mode.  
12  
 
     
• If you attempt to modify any conÞguration parameters 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 conÞgure the RocketLink-G for a broad range of applica-  
tions. This section describes switch locations and discusses the conÞgu-  
ration options available.  
Note By default, the RocketLink-G’s DIP switches are all set to “ON”  
so the NTU can be conÞgured via the console. If that is how you  
will be conÞguring the NTU, skip ahead to the section on conÞg-  
uring the console.. Otherwise, read the following sections to  
manually conÞgure the DIP switch settings.

Figure 1. Location of DIP switches on Model 3088RC  
The three sets of DIP switches on the Model 3088RC are referred to as  
S1, S2 and S3. DIP switch orientation with respect to ON and OFF posi-  
tions is consistent for all switches.  
The DIP switches S1 and S2 can be conÞgured as either ON or OFF.

S2-2: Line Probe  
Line probe is a mechanism that determines the highest rate (192K to

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 used to determine 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 knowledge.

X.21 operation.  
One X.21 modem must be set to Receive-Recover. The other  
X.21 modem must be set to either Internal or External/Network  
clock mode.  
The X.21 modem that is conÞgured as Receive-Recover must  
be DCE.  
The X.21 modem that is conÞgured as Internal must also be  
DCE, but if it is an External/Network clock, then the modem  
must be conÞgured as DTE.

Ethernet operation. The 3088RC/C/AI model does not recover clock  
from the Ethernet network because it is packet-based rather than TDM.  
Therefore, the external clock mode is not valid.

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.

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 signiÞcant 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 conÞgured for  
19200 bps/1 stop bit/ no parity/ XON-XOFF ßow 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 con-  
Þguration reset to factory defaults.  
18  
 
       
Software Upgrades  
The software is upgraded by waiting for the Reset Mode message.Then,  
the user can send an Intel HEX Þle supplied by Patton. After the VT100  
emulator has Þnished sending this Þle, 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 conÞguration and power cycle the unit to  
run the upgraded software.  
ConÞguration Reset to Factory Defaults  
To recover from a forgotten password, the user may reset the unit to its  
factory conÞguration. After seeing the Reset Mode message, the user  
should type the ‘*’ key. This will result in a ‘:’ prompt. At the prompt, the  
user should enter the command reset. This will restore the unit to the fac-  
tory conÞguration. 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 conÞgured to 9600 bps, 1 stop bit, no  
parity, and XON-XOFF ßow control. Use the 1001CC to access the con-  
sole. 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 conÞgure 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 speciÞed  
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 conÞgure 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 inter-  
face. (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.  
19  
 
     
Data Rate: Both the serial/E1 and DSL data rates are set by specifying  
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’ disables the DSL error monitor.  
DSL Error Monitor Interval Time: The length in seconds of  
an interval.  
DSL Error Monitor Interval Count: The number of errored intervals  
allowed before restarting the DSL link.  
DSL Error MonitorTotal Intervals:The number of intervals to inspect  
before disabling the error monitor.  
DSL Error Monitor Startup Delay:The length in seconds to wait after  
the DSL link is established before starting the error monitor.  
Test Modes: 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 panel switches are set to (if the unit is  
populated with them).  
ConÞguration Mode: Whether the 3088RC is conÞgured by DIP  
switches or software.  
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 (suc-  
cess), 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  
20  
 
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  
7
noise power that still allows for BER of less than 1x 10– .  
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 Þnd 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.

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 ConÞguration Commands  
The following commands allow the user to conÞgure the system:  
system set password <password>: Sets the system password.  
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 ßipping the daugh-  
ter-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.  
The following commands allow the user to view the current  
system conÞguration:  
22  
 
 
system show conÞg: Shows the conÞguration of the entire system,  
including DSL and serial/T1/E1 lines.  
Any changes to the system conÞguration or the DSL conÞguration will be  
lost on the next power cycle unless the changes are saved. The com-  
mand system save conÞg 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  
conÞguration mode.  
DSL ConÞguration Commands  
The following commands are used to conÞgure 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 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  
Interval  
totint  
Startup Delay  
Interval 1  
Interval 2  
ßstartdelay⇒ ⇐ßinttime⇒ ⇐ßinttime⇒ ⇐ßinttime⇒ ⇐ßinttime⇒  
The DSL error monitor inspects intervals to see if they have met the error  
threshold (maxint). If the error monitor Þnds 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 begins monitoring errors. After the startup delay, it will  
check the number of errors that have occurred during each (inttime) sec-  
onds 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.  
23  
 
   
The following commands conÞgure 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 number of intervals to inspect  
for errors before disabling the error monitor. If this is set to ‘0’, then the  
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 data rate (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 state, sync state, link speed, error counters, line condition, 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 conÞguration capability via hardware switches  
and jumpers. Sections 4.1 and 4.2 describe all switch and jumper conÞg-  
urations for the 3088RC/K model. Section 4.3 describes the conÞgura-  
tion required for your mDSL modem.  
DIP Switch ConÞguration  
The E1 card has eight internal DIP switches (S1-1 through S1-8). The  
DIP switches can be conÞgured 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 Cod-  
ing that has been provided by your Service Provider.  
S1-1  
Off  
Line Framing & Coding  
HDB3  
AMI  
On  
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 detected. The receiver recognizes these special viola-  
tions and decodes them as zeros.This method enables the network to  
meet minimum pulse density requirements. Use HDB3 unless AMI is  
required in your application .  
27  
 
         
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  
Off  
Option  
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.

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 ConÞguration  
The 3088RC/K model has four jumpers (two position headers): JP4, JP5,  
JP6, and JP7. These jumpers are used to select input and output imped-  
ance 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.  
28  
 
       
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 diagram below and the  
table on the following page to make the proper connections. The con-  
nector 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 dia-  
gram 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 to provide Ethernet LAN extension. The 3088RC/C/AI  
has no switches or jumpers and does not need to be conÞgured. How-  
ever, factors such as the type of medium, throughput across the link and  
clocking mode must be determined by the settings of the baseband  
modems. Please refer to your baseband modem (i.e. 1092, and 1095) to  
make the following settings.  
1. Bit Rate: The DTE rate setting of your base unit corresponds 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 conÞgured for Internal clocking mode and the other unit 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 other base unit settings depend upon your application and on the  
application medium (twisted pair or coaxial cable)  
31  
 
 
Connecting the Interface Driver Board  
This package contains an interface driver board that allows you to conÞg-  
ure 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 instructions below to connect the interface driver board to the  
front function card:  
1. With the function card (such as 3088RC, shown above) pulled out of  
the NetLink rack or clusterbox chassis, locate the driver 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 Board gently onto the socket and re-install  
the function card into the rack or cluster system.  
32  
 
 
Connecting to the 10Base-T Ethernet Port  
The Model 3088RC/C/AI provides line side connections through a termi-  
nal 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 connections up to 330 feet using Type 4  
or 5 cable.  
Figure 9. Model 3088RC Ethernet Connector Pinout

Connecting the 10Base-T Ethernet Port to a Hub . The Model  
3088RC/C/AI 10Base-T interface is conÞgured as DTE (Data Terminal  
Equipment), just like a 10Base-T network interface card in a PC. There-  
fore, 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  
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 conÞgured 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 connecting 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) (Appendix B describes cable requirements) .  
Standard dial-up telephone circuits, or leased circuits that run  
34  
 
     
through signal equalization equipment, or standard, ßat 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 features two LEDs that monitor general operat-  
ing status and the 10Base-T twisted pair link integrity. Figure 11 shows  
the LEDs located directly beneath the RJ-45 jack.

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 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 associated condition  
is removed, the status code will no longer appear.  
Link. Glows green to indicate good link integrity on the 10Base-T  
twisted pair line.

4.0 INSTALLATION  
This section describes the functions of the Model 1001R14 rack chassis,  
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 12) 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 12. 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 modem 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-  
formed by qualified service personnel. Contact Patton  
Electronics Technical support at (301) 975-1007 for  
more information.  
WARNING  
37  
 
       
Powering UpYour 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 sys-  
tem.  
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 swappa-  
ble" rack, it is not necessary for any cards to be installed before applying  
power. The power may be removed at any time without harming the  
installed cards.  
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 connectors. Use the following steps 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-  
tion with respect to voltage, current, anticipated tem-  
CAUTION  
perature, flammability, and mechanical serviceability.  
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.  
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 AWG (0.4mm) (the higher number  
gauges will limit distance). Standard dial-up telephone circuits, or  
leased circuits that run through signal equalization equipment, or  
standard, ßat modular telephone type cable, are not acceptable.  
39  
 
 
The RJ-45 connector on the Model 3088RC’s twisted pair interface is  
polarity insensitive and is wired for a two-wire interface. The signal/pin  
relationships are shown in Figure 13.

perature, flammability, and mechanical serviceability.  
Connecting the Model 3088RC/A/I (V.35) to a “DTE” 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. When connect-  
ing the V.35 interface of the Model 3088RC/A/I to your DTE device, use a  
V.35 straight-through cable. Appendix B.2 on page 55 describes pin  
assignments and signal sources for the Model 3088RC/A/I V.35 inter-  
face.

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, con-  
necting 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 cir-  
cuit cable. Some applications may also require the installation of a tail-  
circuit buffer to account for small differences in clock frequency between  
the 3088RC/A/I and the V.35 DCE (multiplexer).

The Model 3088RC/D/V provides an X.21 interface on a DB-15 female  
connector.The X.21 interface default conÞguration is DCE for connection  
to DTE (data terminal equipment) such as a router. However, the X.21  
interface on the Model 3088RC/D/V may be conÞgured as DTE (data ter-  
minal equipment) for connection to DCE such as a modem or multiplexer.  
When connecting the X.21 interface of the Model 3088RC/D/V to your  
DTE or DCE device, use an X.21 straight-through cable.

5.0 OPERATION  
Once the Model 3088RC is properly conÞgured 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 opera-  
tion of the rack card. Figure 17 shows the front panel location of each LED.  
Table 1 describes each LED’s function.

Loopbacks  
The 3088RC supports both Local Analog Loopbacks (LAL) and Remote  
Digital Loopbacks (RDL). These can be initiated either from the optional  
front panel switches or by the console command dsl set loopback  
<off|lal|rdl>. The data path for the LAL is shown in Figure 19.

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 gen-  
erator/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 20.

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 way errors are generated in the 511E pat-  
tern 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 conÞgure 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. ConÞgure a terminal emulation program (e.g., Hyperterminal) on PC  
(near-end) for 19200 bps, 8 data bits, no parity, 1 stop bit, no ßow  
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.  
47  
 
       
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 following message appears: Console: Remote console  
timed out trying to con-nect. Enter the command remote con-  
sole 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 remote  
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 should now be logged into the remote 3088RC (far-end) via the  
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.  
48  
 
Figure 22 is a screenshot of opening a typical remote console session:

Message informs us that we are now  
connected to the 3088RC (Far End) console  
We can now enter commands on  
the remote console  
Figure 22. 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 fol-  
lowing is what is displayed 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.  
49  
 
   
>
The timeout period is a Þxed, non-conÞgurable parameter of 5 minutes. If  
the remote 3088RC (far-end) has received no command within 5 min-  
utes, it automatically terminates the RCS. Once the RCS is terminated,  
the PC (far-end) can establish a local console session if desired. How-  
ever if the PC (near-end) wishes to re-establish a RCS, it is able to do so  
whether or not the PC (far-end) is in an active local session, because 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 indeÞnitely for input (which is the system upgrade  
image) from the local console port of the 3088RC (far-end). If this  
command is entered, 3088RC (Far End) will have to be power-cycled.  
Do not attempt a software upgrade of the remote unit  
over the Remote Control Session.

Do not issue this command to a far-end unit. If you were  
to do so, the near-end 3088RC would no longer be able  
to communicate with the far-end 3088RC.  
CAUTION  
5.4 SOFTWARE UPGRADE  
The Model 3088RC is software upgradeable through the console port.  
Software images will be available in Intel Hex Þle format.  
The software upgrade feature is available either by powering up the  
Model 3088RC with all DIP switches set to the 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 pro-  
cess. When the software upgrade completes, it will print a message stat-  
ing that it is complete and the number of errors, if any, that occurred.  
Errors may occur during the software upgrade if the image is corrupt or if  
there is a disruption in the console port connection. The Model 3088RC  
will print a message to the console port if it encounters any errors. In the  
event of an error, the portions of the old image may have been overwrit-  
ten, and the unit may not be able to boot into operational mode. However,  
the unit may still boot into the software upgrade, so a new software  
image can still be loaded to bring the unit back to an operational state.  
Here is the software upgrade procedure:  
1. Remove all cards from the rack except for the card that you intend to  
upgrade.  
2. Obtain the software image Hex Þle 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. ConÞgure HyperTerminal for 19200 bps, 8 bits, 1 stop bit, no parity,  
XON-XOFF.  
51  
 
 
7. Open Model 3088RC Console (via 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 conÞguration.  
10.Turn on the Model 3088RC. It now operates with the upgraded soft-  
ware.  
5.5 RESET CONFIGURATION TO FACTORY DEFAULT  
The conÞguration can be reset to factory defaults from the software reset  
mode. This allows a user to recover from a forgotten password. To reset  
to the conÞguration, 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). ConÞg-  
ure the emulator for 19200 bps,1 stop bit, no parity, X-ON X-OFF  
ßow 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 mes-  
sage: 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  
conÞguration.  
9. Set the DIP switches to the desired conÞguration. Power cycle the  
unit to begin using the new conÞguration.

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