4.0 CONFIGURATION
The Model 3088 (see figure 1) has two configuration modes, DIP s witch
and software.
Figure 1.
Model 3088 (3088/D version shown)
DIP switch configuration mode is entered b y starting the unit with the DIP
switches in any position other than all OFF or all ON. In DIP switch configuration mode, the DIP switch settings are read at system startup and used to
configure the unit. Once the unit has started in DIP switch mode it will
remain in DIP switch mode, and its settings cannot be changed. Console
commands used to configure the unit will report that the unit is in DIP switch
configuration and will not change the configuration. Like wise, EOC v ariables
cannot be used to configure the device. Also note that changing the DIP
switch settings while the unit is running will hav e no eff ect on the configur ation as the DIP switches are only read on startup.
Software configuration mode is entered by starting the unit with the DIP
switches set to all ON. The system then reads an y configur ation that might
have been sa v ed to FLASH. If no configuration has been saved, then the
factory defaults are loaded. The unit may be further configured by console
commands or by EOC.

4.2 SYSTEM RESET MODE
System reset mode is entered by switching all DIP switches to the OFF
position and power cycling the unit. A VT100 emulator configured for
19,200 kbps/1 stop bit/ no parity/ XON-XOFF flow control can be used to
access the console. Upon restart, you will see the message
“Reset Mode”.
System reset mode provides two functions:
• Software upgrades
• Configuration reset to factory defaults
Software Upgrades
The software is upgraded by waiting for the “Reset Mode” message.
Then, the user can send an Intel HEX file supplied by Patton. After the
VT100 emulator has finished sending this file, the 3088 will respond with
a message 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.
12
Page 13
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” 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 factory configuration. The unit can then be restarted with the settings
in place.
4.3 DIP SWITCH SETTINGS
The 3088 can be configured with DIP switches. If the DIP switches are
set to anything other than all ON, then the unit will be in DIP switch configuration. In DIP switch configuration, the console and EOC cannot be
used to change configuration.
The following table describes the DIP switch functions.

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 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.

Note DSL Link State vs. DSL Sync 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
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.

system set clockmode <internal|external|receiverecover>:
Sets
the clock mode. Internal clock mode means the 3088 provides the
clock to both the DSL and the serial interface. External clock mode
means the 3088 uses the serial transmit clock as its DSL transmit
clock (V.35 only). Receive recover clock mode means that the 3088
uses the DSL receive clock as its DSL transmit clock and as the serial
receive clock.

DCE to provide the clock used f or both tr ansmitting data and for
sampling receive data. When the 3088/D 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 3088/D 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 3088 is set for either DCE or DTE by flipping the daughtercard. The 3088 is a DCE if DCE points away from the serial
interface toward the front of the 3088. Note that this is different
than the 3086/D.

DSL Error Monitor
Startup Delay Interval 1 Interval 2 … Interval totint
ïflstartdelayðïflinttimeðïflinttimeðïflinttimeðïflinttimeð
The DSL error monitor inspects intervals to see if they hav e met the error
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 begins monitoring errors. After the startup delay, it will
check the number of errors that have occurred 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 n umber of intervals to inspect
for errors bef ore disab ling the error monitor. If this is set to ‘0’, then the
error monitor will run continuously.
22
Page 23
• dsl set errmon startdelay <startdelay>: Sets the n umber of seconds
to wait after the DSL link comes up before the error monitor starts
inspecting intervals.
The following commands display the current DSL configuration:
• dsl show annex: Shows the currently selected G.SH Annex.
• dsl show lineprobe: Shows whether or not Line Probe is
currently enabled.
• dsl show loopback: Shows which loopback is currently running.
• dsl show pattern: Shows what PRBS pattern is currently running.
The following commands display the current DSL error
monitor configuration:
• dsl show errmon maxint: Shows the maximum errors allowed in an
interval before it is considered errored.
• dsl show errmon inttime: Shows the length in seconds of
each interval.
• dsl show errmon intcnt: Shows the number of errored intervals
allowed before restarting.
• dsl show errmon totint: Shows the number of intervals to monitor
before disabling the error monitor.
• dsl show errmon startdelay: Shows the length in seconds to wait
after the DSL link comes up before starting the error monitor.
Changing the data rate (system 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.

4.4 ROCKETLINK PLUG ‘N’ PLAY
The RocketLink Plug ‘n’ Play feature allows ISPs, carriers and PTTs to
quickly upgrade the link speed for a customer without requiring a visit to
re-configure the Customer Premise (CP) Model 3088. This feature also
allows service providers to set up all of the configurations at the Central
Office (via the ForeFront AIS system) before installing the stand alone
units, saving time spent configuring or re-configuring DIP switches.
Note RocketLink Plug ‘n’ Play is only available when using a Fore-
Front Model 3096RC as the CO unit.
The RocketLink Plug ‘n’ Pla y f eature allows the user to configure the DTE
rate (bandwidth allocation, see Switches S1-1 through S1-7) of the CP
unit via the
ForeFront Model 3096RC at the Central Office (CO). The
stand alone unit at the Customer Premise (CP) site will automatically
configure itself to the DTE rate (Bandwidth Allocation) defined at the
Model 3096RC. Other configuration parameters remain in the
default setting.
26
Page 27
Follow the instructions below to activate RocketLink Plug ‘n’ Play
between CO (Model 3096RC and CP (Model 3088) units:
• Set the Model 3096RC (CO) to either Internal or External clocking
mode as defined by the application.
• Set the Model 3088 (CP) to “RocketLink Plug-and-Play CP” by setting
S1 and S2 DIP switches in the ON position as described in figure 4.

When the CO and CP units connect over DSL, the CP will enter a predefined default configuration (Receive Recovered Clocking). During the
negotiation process between the units, the CO unit will configure the
DTE rate/line rate on the CP unit as defined by the settings of the CO
unit. When additional bandwidth is required, only the configuration of the
CO unit should be changed. This feature gives ISPs , LECs and PTTs the
ability to provision bandwidth on an as needed basis to customers.

5.0 INSTALLATION
Once the Model 3088 is properly configured, it is ready to connect to the
twisted pair interface, to the serial port, and to the power source. This
section tells you how to make these connections.
5.1 CONNECTING THE TWISTED PAIR INTERFACE
The Model 3088 supports communication between two DTE devices
as follows:
Using 24 AWG (.5 mm) wire:
• up to 32,000 feet (9.7 km) at 192 kbps
• up to 18,500 feet (5.6 km) at 2.312 Mbps on
Using 26 AWG (.4 mm) wire:
• up to 23,000 feet (7 km) at 192 kbps
• up to 13,200 feet (4 km) at 2.312 Mbps on
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 3088 needs one twisted pair of
metallic wire. This twisted pair must be unconditioned, dry, metallic
wire, between 19 (.9mm) and 26 AWG (.4mm) (the higher 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.
28
Page 29
The RJ-45 connector on the Model 3088’s twisted pair interface is polarity insensitive and is wired for a two-wire interface. The signal/pin relationships are shown in figure 5.

5.2 CONNECTING THE MODEL 3088/CA (V.35)
SERIAL INTERFACE
Model 3088/CA supports V.35 serial port connections. This section
describes how to connect the serial ports to your V.35 equipment.
Connecting the Model 3088/CA (V.35) to a “DTE” Device
The Model 3088/CA provides a V.35 DCE (data circuit terminating equipment) interface on an DB-25 female connector. As a DCE, this interface
is designed to connect to DTE equipment, such as a router. When connecting the V.35 interface of the Model 3088/CA to your DTE device, use
a V.35 straight-through cable (See figure 6). Appendix C describes pin
assignments and signal sources for the Model 3088/CA V.35 interface.
When purchasing or constructing an interface cable, refer to the pin diagrams in Appendix C as a guide.

Connecting the Model 3088/CA (V.35) to a “DCE” Device
The Model 3088/CA provides a V.35 DCE (data circuit terminating equipment) interface on an DB-25 female connector. As a DCE, this interface
is designed to connect to DTE equipment, such as a router. However,
tail-circuit applications require connection to another DCE equipment,
such as a multiplexer. When connecting the V.35 interface of the Model
3088/CA to your DCE device (see figure 7), use a V.35 tail circuit cable.
Some applications may also require the installation of a V.35 tail-circuit
buffer to account for small differences in clock frequency between the
3088/CA and the V.35 DCE (Multiplexer).

5.3 CONNECTING THE MODEL 3088/D (X.21) SERIAL INTERFACE
Model 3088/D supports X.21 serial port connections. This section
describes how to connect the serial ports to your X.21 equipment.
Connecting the Model 3088/D (X.21) to a “DCE” or “DTE” Device
The Model 3088/D provides an X.21 interface on a DB-15 female connector. The X.21 interface default configuration is DCE for connection to
DTE (data terminal equipment) such as a router. However, the X.21 interface on the Model 3088/D may be configured as DTE (
data terminal equip-
30
Page 31
ment) for connection to DCE such as a modem or multiplexer. When
connecting the X.21 interface of the Model 3088/D to your DTE or DCE
device, use an X.21 straight-through cable (See figure 8).

To change the DCE/DTE orientation from the def ault position (DCE), you
must open the case Model 3088/D case.
Opening the Case
To open the Model 3088/D case, insert a flat head screw driver into an
open slot on both sides of the case, as in figure 9. Twist the screw driver
head slightly and the top half of the case will separate from the lower
half, as in figure 9. Be careful not to damage the PC-board
mounted components.

Page 32
The DCE/DTE strap is located on the top side of the 3088/D pc board
(See figure 10, below). The arrows on the top of the strap indicate the
configuration of the X.21 port (for example, if the DCE arrows are pointing toward the DB-15 connector, the X.21 port is wired as a DCE).
Change the DCE/DTE orientation by pulling the strap out of its socket,
rotating it 180º, then plugging the strap back into the socket. You will see
that the DCE/DTE arrows now point in the opposite directions, showing
the new configuration of the X.21 port. To close the case, fit the 2 halves
together snugly and snap them back in place.

5.4 CONNECTING POWER
The Model 3088 uses a 5 VDC, 2A universal input 100–240 VAC, power
supply (center pin is +5V). The universal input power supply has a male
IEC-320 power entry connector. This power supply connects to the
Model 3088 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 3088 powers up as soon as it is plugged into an AC outlet-there is no power switch.
WARNING
There are no user-serviceable parts in the
power supply section of the Model 3088. Fuse
replacement should only be performed by qualified service personnel. Contact Patton Electronics Technical support at (301)975-1007, via our
web site at www.patton.com, or by e-mail at
support@patton.com, for more information.

6.0 OPERATION
Once the Model 3088 is properly configured and installed, it should operate transparently. This sections describes power-up, reading the LED
status monitors, and using the built-in loopback test modes.
6.1 POWER-UP
To apply power to the Model 3088, first be sure that you have read section 5.4, “Connecting Power” on page 32, and that the unit is connected
to the appropriate power source. Power up the unit.
6.2 LED STATUS MONITORS
There are four LEDs that provide feedback on the state of the unit.
Figure 11 shows the location of the front panel LEDs. F ollowing figure 10
is a description of each LED’s function.
Figure 11. Model 3088/CA front panel
Power (Green)
The Power LED glows solid during normal operation. At startup, during
the POST, the LED blinks once every second. If the POST fails, the unit
does not enter normal operation, and the LED blinks once every
0.4 seconds.
DSL (Green)
The DSL LED glows solid while a DSL link is established. While the DSL
link is training it blinks once every second.
33
Page 34
Term (Green)
The Term LED glows solid under the following circumstances:
• 3088/CA with V.35 interface: If the serial interface has asserted DTR
• 3088/D with the X.21 interface:
– Configured as DCE: Indicates that the “Control” signals have
been asserted.
– Configured as DTE: Indicates that the “Indication” signals have
been asserted
TM/ER (Red)
The TM/ER LED is used to indicate that a test mode is in prog ress or an
error has been detected. It blinks once e v ery second while a test mode is
starting. It glows solid while a test mode is in progress . It b links once if an
error is detected either during a test mode, or in normal DSL operation.
6.3 TEST MODES
The 3088 offers test modes in the form of loopbacks, PRBS pattern generators, and combinations of both. This section discusses how the test
modes work. Figure 12 is a block digram of the Model 3088 with respect
to test modes.

Loopbacks
The 3088 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 13.

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 is conjunction
with an LAL should result in no error detected by the meter.
The data path for the RDL is shown in figure 14.

The RDL causes the remote unit to loop the data received from the DSL
line back to the DSL line.
Patterns
The 3088 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 pattern generates CRC errors. This can cause the DSL error monitor to
restart the link if the thresholds are set low enough.

7.0 REMOTE CONSOLE MANUAL INFORMATION
The PC user (near-end) may configure and verify status of the remote
3088 (far-end) via a Remote Console session. The PC user must log
onto the 3088 (near-end) unit to establish a remote console session.
Once done, the remote 3088 (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.

7.1 ESTABLISHING A REMOTE CONSOLE SESSION
How to Connect
The following steps are to estab lish a connection to the remote 3088 (f arend) via Remote Console Session (RCS):
1. Configure a terminal emulation program (e.g., Hyperterminal) on PC
(near-end) for 19.2 kbps, 8 data bits, no parity, 1 stop bit, no flow
control. Connect it to the RS-232 console port of the 3088 (nearend).
2. At the password prompt, log in to the near-end Model 3088.
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
connection established
Console: Remote console
.
— If a DSL link is not established, or for some other reason the
3088 (far-end) does not respond in a reasonable amount of
time, the follo wing message appears:
timed out trying to connect
. Enter the command remote
Console: Remote console
console again.
36
Page 37
— If 3088 (Far End) already has an activ e remote console session
open, you will see the message
nection request rejected
. This can also happen if the remote
Console: Remote console con-
3088 (far-end) has an established remote console session with
the local 3088 (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 3088 (near-
end) and the remote console session of the 3088 (far-end)
should be different for the purpose of security.
7. You should now be logged into the remote 3088(far-end) via the
remote console session. The communication with the remote 3088
(far-end) is essentially the same as having a local
console connection.
Note The local or remote 3088 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
3088 (far-end) sends a message to the PC (far-end) stating
“Console: Remote console connection is open.”
37

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

The timeout period is a fixed, non-configurable parameter of 5 minutes.
If the remote 3088 (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. However 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 3088 (farend) waits indefinitely for input (which is the system upgrade image)
from the local console port of the 3088 (far-end). You must powercycle the remote 3088 (far-end) to return it to the normal operational
state. If this command is entered, 3088 (Far End) will have to be
power-cycled.
• dsl set loopback lal: When this command is issued over the RCS,
clearly the PC (near-end) can no longer communicate with the remote
3088 (far-end). See the diagram. Consequently the remote 3088 (farend) can no longer receive any commands over the DSL channel from
the PC (near-end). To recover from this situation, the DSL link will
have to be dropped prior to establishing the RCS again. A short explanation is in order. Since the remote 3088 (far-end) no longer receives
any commands from the PC (near-end), the RCS will time out in 5 minutes and attempts to send a disconnect message back to the local
39
Page 40
3088 (near-end). However the local 3088 (near-end) is unable to
receive this message and the local 3088 (near-end) does not know to
terminate the RCS. F or this reason, the DSL link must be dropped and
re-established. At this point, the RCS can be established anew.

Whether a DSL link is up or not has no effect on the operation of the

8.0 MODEL 3088 SOFTWARE UPGRADE FEATURE
The 3088 is software upgradeable through the console port. Software
images will be available in Intel Hex file format.
The software upgrade f eature is av ailable either b y pow ering up the 3088
will all dipswitches set to the “Off” position, or by entering the “system
upgrade” command on the command line interface. The software
upgrade takes appro ximately 5 minutes to complete . The 3088 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 software upgrade if the image is corrupt or if
there is a disruption in the console port connection. The 3088 will print a
message to the console port if it encounters any errors. In the e v ent 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, 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. Obtain a software image Hex file.
2. Turn off the 3088.
3. Switch all DIP switches to the “Off” position.
4. Turn on the 3088.
5. Transfer the software image hex file through the console (8 bits/no
parity/1 stop bit/XON-XOFF flow control).
6. When the transfer completes, turn the 3088 off.
7. Set the DIP switches for the proper configuration.
8. Turn on the 3088. It is now running the upgraded software.

9.0 RESET CONFIGURATION TO FACTORY DEFAULTS
The configuration 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 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). Config-
ure the emulator for 19,200 kbps/1 stop bit/no parity/X-ON X-OFF
flow control.
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 configuration.
9. Set the DIP switches to the desired configuration. Power cycle the
unit to begin using the new software.
