3.0 CONFIGURATION
This section describes the location and orientation of the Model
3088RC’s configuration switches and jumpers, and provides detailed
instructions for all possible settings. Each 3088RC model has different
configuration requirements, depending on the card’s serial interface.
You can configure the 3088RC using either the software (CLI via a
1001CC port) or the hardware (via DIP switches).
3.1 ABOUT SOFTWARE (CLI) CONFIGURATION
To use software configuration you must set DIP switches S1 and S2 to
the ON position, and set DIP Switch S3 to the management address,
before powering-up the RocketLink-G. When DIP switches S1 and S2
are set to ON, the RocketLink-G will operate in software-configuration
mode. When set for software-configuration mode the RocketLink-G will
read any configuration data previously saved to FLASH memory during
system power-up. If no configuration data was previously saved to
FLASH, then the Rocket Lin k-G w il l loa d th e fac tory -de fau lt c onf igu r ati on
from FLASH memory. After power-up, you may use console commands
or the Embedd ed Operations Channel (EOC) to mo dif y the c on f igu rati on
parameters.
3.2 ABOUT HARWARE (DIP SWITCH) CONFIGURATION
To use DIP-switch configuration you must first set the DIP switches to a
position other than all OFF or all ON before powering-up the RocketLink-
G. When all the DIP switch es are se t to any po sitio n other than all OFF or
all ON the RocketLin k-G will ope rate in ha rdwa re (DIP-s witc h)-c onf igu ration mode. In DIP-switch-configuration mode the RocketLink-G will read
the DIP-switch setti ngs du rin g system st artup an d confi gure its elf ac cording to the switch settings.
Once you power-up the RocketLink-G in DIP-switch mode it will operate
in DIP-switch mode until powered down. When operating in DIP-switch
mode you cannot change any configuration settings:
• Changing the DIP switch settings while the device is running will not
modify the operating configuration because the RocketLink-G only
reads the DIP switches during s ystem startup.
• If you attempt to modify the configuration by issuing console commands, the dev ice wil l not e xecut e your c omma nds. Inste ad , the Roc ketLink-G will respond with a message indicating the device is
operating in DIP-switch-configuration mode.
14
• If you atte mpt to mo dify any confi gu rati on 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 configure the RocketLink-G for a broad range of applications. This section describes switch locations and discusses the configuration options available.
Note By default, the RocketLink-G’s DIP switches are all set to “ON”
so the NTU can be configured via the console. If that is how you
will be configuring the NTU, skip ahead to the section on configuring the console.. Otherwise, read the following sections to
manually configure the DIP switch settings.
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 positions is consistent for all switches.
The DIP switches S1 and S2 can be configured as either ON or OFF.

S1-8: TX Clock
S2-1: Front Panel Switches
The 3088RC uses front panel switches to control test modes. They may
be disabled so that the 3088RC ignores them.
S2-2: Line Probe
Line probe is a mechanism that determines the highest rate (192K to
2304K) that the DSL link can reliab ly 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 co uld be us ed to determine the best rate the lin e 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 us er’s knowle dge.
S2-3: Annex A/B
Annex A is typically used in North American-like networks, whereas
Annex B is typically used in European-like networks. The different
annexes specify different PSD (power spectral density) masks because
of the difference in T1 and E1 PSDs.

be DCE.
— The X.21 modem that is configured as Internal must also be
DCE, but if it is an External/Network clock, then the modem
must be configured 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.

ON ON Internal The on-board oscillator in
the 3088RC provides clock
for both serial and DSL
lines.

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.
S2-7: DTE Interface Type
The DTE interface type nee ds to be set based on th e rear modul e. Set to
E1 if using the /K model. Set to normal if using any other model.
S3-1 through S3-8: Management Address
Each rack card in a chassis must have a unique management address.
The 1001CC and 1001MC use this address to activate and deactivate
the rack card's management interface. This is necessary because all
rack cards in a chassis communicate over the same bus, so only one
card can be active at a time.
This address can be set to any value between 0 and 255. Set S3 to the
binary representation of the number (ON=0 and OFF=1). S3-8 is the
most significant bit.
3.4 ABOUT SYSTEM RESET MODE
To enter system reset mode, switch all DIP switches to the OFF position
and power cycle the unit. You can use a VT100 emulator configured for
19200 bps/1 stop bit/ no parity/ XON-XOFF flow control to access the
console. Upon restart, you will see the message “Reset Mode”. The
3088RC automatically communicates through the 1001CC in reset
mode, and does not wait for its address.
System reset mode provides two functions: software upgrades and configuration reset to factory defaults.

Software Upgrades
The softwa re is upgra ded by wait ing for the Res et Mode m essage. Then,
the user can send an Intel HEX file supplied by Patton. After the VT100
emulator has finished sending this file, the 3088RC will respond with a
mes-sage stating how many errors were detected. The user may then
set the DIP switches to the desired configuration and power cycle the
unit to run the upgraded software.
Configuration Reset to Factory Defaults
To recover from a forgotten password, the user may reset the unit to its
factory configuration. After se eing the Reset Mode message, the user
should type the ‘*’ key. This will result in a ‘:’ prompt. At the prompt, the
user should ent er the co mman d reset. This wil l restore the uni t to the fa ctory configuration. The unit can then be restarted with the settings in
place.
3.5 CONFIGURING THROUGH THE CONSOLE
The 3088RC offers a console command line interface. To access the
console, use a VT100 emulator configured to 9600 bps, 1 stop bit, no
parity, and XON-XOFF flow control. Use the 1001CC to access the console. Type CTRL+B <address> <enter> to activate the console. Log into
the unit using the default password. No username will be needed.
Note Log in with the default password superuser.
You can configure the following variables through the console:
• Password: The password used to login to the console.
• Circuit ID: The circuit ID communicated to other units via EOC. EOC
(Embedded Operations Channel) is an out-of-band channel specified
in the G.991.2 standard for SHDSL. We use standard EOC messages
for our remote loopback. The 3088RC also supports proprietary EOC
messages that allow a 3096RC to configure it.
• Clock Mode: The following options are available:
— Internal: The internal oscillator in the 3088RC provid es the
clock to both the serial/T1/E1 and DSL interfaces.
— External: The serial interface provides the clock for the DSL
interface (V.35, X.21). It must be set to DTE for the X.21 interface. (This mode is invalid for the Ethernet model).
— Receive Recover: The 3088RC recovers the clock from the
DSL interface and provides it to the serial/E1 interface.
