Model 3088 Series User Manual

2 • Configuration

Introduction
You can configure the RocketLink-G (see figure 3) in one of two ways:
• Software configuration using command line interface (CLI) via the console port
• Hardware configuration via DIP switches

Figure 3. RocketLink-G (Model 3088/D shown)

Software (CLI) configuration
To use software configuration you must set all the DIP switches to the ON position before powering-up the
RocketLink-G. When all the DIP switches 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 RocketLink-G will load the factory-default configuration from FLASH memory. After
power-up, you may use console commands or the Embedded Operations Channel (EOC) to modify the configuration parameters.
Hardware (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 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)-configuration mode. In DIP-switch-configuration mode the RocketLink-G will read the DIP-switch settings during system startup and configure 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 powereddown. 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 will not execute your
commands. Instead, the RocketLink-G will respond with a message indicating the device is operating in
DIP-switch-configuration mode.

Configuring the DIP switches
The Model 3088 is equipped with two 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 RocketLink Plug ‘n’ Play from a 3096RC. If
that is how you will be configuring the NTU, skip ahead to section “Console” on page 32. Otherwise, read the following sections to manually configure the DIP switch settings.

The two sets of DIP switches are externally accessible from the underside of the Model 3088 (see figure 4).

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 19,200 kbps/1 stop bit/ no parity/ XON-XOFF flow control 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.
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.
DIP switch settings
You can configure the 3088 by setting the DIP switches to the desired positions before you power up the RocketLink-G. If the DIP switches are set to anything other than all OFF or all ON, the RocketLink-G will operate
in DIP switch configuration mode. Once the device is powered up and operating in DIP switch configuration
mode, you cannot change configuration by any method until you power it down again.

Console
The 3088 offers a console command line interface. To access the console, use a VT100 emulator configured to
19,200 kbps, 1 stop bit, no parity, and XON-XOFF flow control. Log into the unit using the default password. No username will be needed.
Note

For software release 2.1.2, log in with the default password patton.
For software release 2.1.3, log in with the default password superuser.

Through the console, the following variables can be configured:
• 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 3088 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 3088 provides the clock to both the serial/T1/E1 and
DSL interfaces.
- Network: The T1/E1 interface provides the clock for the DSL interface (T1/E1 only).
Introduction

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).
• Configuration Mode: Whether the 3088 is configured 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 (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.

• 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

2 • Configuration

System Configuration Commands
The following commands allow the user to configure the system:
• system set password : Sets the system password.
• system set circuitid : Sets the circuit ID.
• system set clockmode : Sets the clock mode. Internal clock
mode means the 3088 provides the clock to both the DSL and the serial/T1/E1 interface. External clock
mode means the 3088 uses the serial/T1/E1 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/T1/E1 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 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 daughter-card. 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.

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 configuration or the DSL configuration 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 <1–24 (t1) | 32 (e1) | 72 (v.35, x.21)>: Sets the number of timeslots. For T1/E1 NTU’s,
the number of T1/E1 timeslots is set simultaneously. The T1/E1 timeslot mapping will be set to the
default. The data rate is calculated by the equation: data-rate = #timeslots x 64k.
• dsl set annex : Set the annex.
• dsl set lineprobe : Enable or disable line probe.
• dsl set loopback : Start or stop loopbacks.
• dsl set pattern : Start or stop PRBS generator and BER meter.

The DSL error monitor inspects intervals to see if they have 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 : 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 : Sets the length of each interval.
• dsl set errmon intcnt : Sets the number of errored intervals that causes the DSL link to restart.
• dsl set errmon 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 : 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 information: 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.
T1/E1 Configuration Commands
t1e1 set linetype
Select the T1 or E1 framing format to use.

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 ForeFront Model
3096RC running software release 1.5.7 or later. Since the 3096RC is CO,
the RocketLink must be CP, which is the default.

The RocketLink Plug ‘n’ Play feature allows the user to configure 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 may likewise be modified from their default setting.
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.

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.
Connecting the twisted pair interface
The Model 3088 supports communication between two DTE devices as follows:

CAUTION

The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to voltage, current, anticipated temperature, 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 3088 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, flat modular telephone type cable, are not acceptable.
The RJ-45 connector on the Model 3088’s twisted pair interface is polarity insensitive and is wired for a twowire interface. The signal/pin relationships are shown in figure 7.

Introduction
Once the Model 3088 is properly configured and installed, it should operate transparently. The following sections describe power-up, reading the LED status monitors, and using the built-in loopback test modes.
Power-up
To apply power to the Model 3088, first be sure that you have read section “Power input connector” on
page 16, and that the unit is connected to the appropriate power source. Power up the unit.
LED status monitors
There are four LEDs that provide feedback on the state of the unit. Figure 19 shows the location of the front
panel LEDs. Following figure 19 is a description of each LED’s function.

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.
Link (Green) (Models K and T only)
The Link LED indicates the status of the T1/E1 link. It is dark when it detects no signal. It blinks once per second when it detects signal, but not valid framing. It glows solid when it detects valid framing.

Introduction

Model 3088 Series User Manual

Term (Green) [Models C and D]
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 progress or an error has been detected. It blinks
once every second while a test mode is starting. It glows solid while a test mode is in progress. It blinks once if
an error is detected either during a test mode, or in normal DSL operation.
LOS (Red) [Models K and T]
The LOS LED blinks once per second to indicate either framing errors or clock slips. Clock slips are often
caused by a mis-configured clock mode.
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. The following 3088 models have toggle switches available on
the front panel for operating test modes:
• 3088/CAS/E
• 3088/DS/E
• 3088/KS/E

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 23.

The RDL causes the remote unit to loop the data received from the DSL line back tow 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 . 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.

Model 3088 Series User Manual

5 • Remote console operation

Introduction
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.

Establishing a Remote Console Session
How to Connect
The following steps are to establish a connection to the remote 3088 (far-end) 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 (near-end).
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 Console: Remote console connection established.
– 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 following message appears: Console: Remote console timed out trying to connect. Enter the command remote console again.
– If 3088 (Far End) already has an active remote console session open, you will see the message Console:
Remote console connection request rejected. This can also happen if the remote 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.

Introduction

Model 3088 Series User Manual

5 • Remote console operation

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.

Figure 25 is a screenshot of opening a typical remote console session:

the remote console

Figure 25. 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.

Introduction

Model 3088 Series User Manual

5 • Remote console operation

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 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.
>

The timeout period is a fixed, non-configurable parameter of 5 minutes. If the remote 3088 (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-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 (far-end)
waits indefinitely for input (which is the system upgrade image) from the local console port of the 3088
(far-end). If this command is entered, 3088 (Far End) will have to be power-cycled.
Do not attempt a software upgrade of the remote unit over the
Remote Control Session.

Introduction
The Model 3088 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 3088 with all DIP switches set to
the OFF position, or by entering the system upgrade command on the command line interface. The software
upgrade takes approximately 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 Model 3088 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 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 the software image Hex file for the 3088.
2. Turn off the Model 3088.
3. Make a note of the current DIP switch settings, then set all DIP switches to the OFF position.
4. Turn on the Model 3088.
5. Configure HyperTerminal for 19.2 kbps, 8 bits, 1 stop bit, no parity, XON-XOFF.
6. Open Model 3088 Console (via HyperTerminal or other terminal emulation program).
>>Transfer
>>Send Text File…
>>Set “Files of Type:” to “All files (*.*)”
>>Select 033252Z.hex

7. When the transfer completes, turn off the Model 3088.
8. Set the DIP switches for the proper configuration.
9. Turn on the Model 3088. It now operates with the upgraded software.

Radio and TV Interference (FCC Part 15)
This device generates and uses radio frequency energy, and if not installed and used properly-that is, in strict
accordance with the manufacturer’s instructions-may cause interference to radio and television reception. The
device has been tested and found to comply with the limits for a Class A computing device in accordance with
specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reasonable protection from
such interference in a commercial installation. However, there is no guarantee that interference will not occur
in a particular installation. If the device does cause interference to radio or television reception, which can be
determined by disconnecting the unit, the user is encouraged to try to correct the interference by one or more
of the following measures: moving the computing equipment away from the receiver, re-orienting the receiving
antenna and/or plugging the receiving equipment into a different AC outlet (such that the computing equipment and receiver are on different branches).
