3.0 CONFIGURATION
This section describes the location and orientation of the Model 3088RC’s configuration switches and jumpers, and provides detailed instructions for all possible settings. Each 3088RC model has different configuration requirements, depending on the card’s serial interface.
You can configure the 3088RC using either the software (CLI via a 1001CC port) or the hardware (via DIP switches).
3.1 ABOUT SOFTWARE (CLI) CONFIGURATION
To use software configuration you must set DIP switches S1 and S2 to the ON position, and set DIP Switch S3 to the management address, before powering-up the RocketLink-G. When DIP switches S1 and S2 are set to ON, the RocketLink-G will operate in software-configuration mode. When set for software-configuration mode the RocketLink-G will read any configuration data previously saved to FLASH memory during system power-up. If no configuration data was previously saved to FLASH, then the RocketLin k-G wil l loa d th e fac tory -de fault configuration from FLASH memory. After power-up, you may use console commands or the Embedded O pe rati ons C h ann el (EO C) to modify the configurati on parameters.
3.2 ABOUT HARWARE (DIP SWITCH) CONFIGURATION
To use DIP-switch configuration you must first set the DIP switches to a position other than all OFF or all ON before powering-up the RocketLink­G. When all the DIP sw itches are set to any posi tion ot her than al l OFF or all ON the RocketLink-G will ope rate in ha rdwa re (DIP-s witc h)-configura­tion mode. In DIP-switch-configuration mode the RocketLink-G will read the DIP-switch setting s durin g sys tem st artup and co nfigure its elf accord­ing to the switch settings.
Once you power-up the RocketLink-G in DIP-switch mode it will operate in DIP-switch mode until powered down. When operating in DIP-switch mode you cannot change any configuration settings:
• Changing the DIP switch settings while the device is running will not modify the operating configuration because the RocketLink-G only reads the DIP switches during system startup.
• If you attempt to modify the configuration by issuing console com­mands, the device w ill n ot execut e yo ur comma nds. In stead , the R ock­etLink-G will respond with a message indicating the device is operating in DIP-switch-configuration mode.
13
• If you attempt to modify any configuration p arameters via the EOC (by changing (EOC variables), the RocketLink-G will not execute your changes.
3.3 CONFIGURING THE DIP SWITCHES
(V.35, X.21, and Ethernet
Models)
The Model 3088RC is equipped with three sets of DIP switches, which you can use to configure the RocketLink-G for a broad range of applica­tions. This section describes switch locations and discusses the configu­ration options available.
Note By default, the RocketLink-G’s DIP switches are all set to “ON”
so the NTU can be configured via the console. If that is how you will be configuring the NTU, skip ahead to the section on config­uring the console.. Otherwise, read the following sections to manually configure the DIP switch settings.
S3 S2 S1
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.

S2-2: Line Probe
Line probe is a mechanism that determines the highest rate (192K to 2304K) that the DSL link can reliably support. This takes place during training. The DSL rate will be set to the rate that line probe determines. Note that both the CO and CPE unit must have line probe enabled for it to take effect.
Line probe could be us ed to d ete rmine the best rate the line will support, and then the user could set the units for that rate and disable line probe so that the rate won’t change without the user’s knowle dge .

S2-4 through S2-5: Clock Mode
The RocketLink-G can operate in one of three clock modes: internal, external, or receive-recover.
S2-4 S2-5 Clock Mode Description
ON ON Internal The on-board oscillator in
the 3088RC provides clock for both serial and DSL lines.
OFF ON External 3088RC uses the RX clock
from the serial interface as the clock for the DSL link.
ON OFF Receive-
Recover
OFF OFF Reserved
X.21 operation. There are a few things to note about clock modes and X.21 operation.
— One X.21 modem must be set to Receive-Recover. T he other
X.21 modem must be set to either Internal or External/Network clock mode.
— The X.21 modem that is configured as Receive-Recover must
be DCE.
3088RC uses the RX clock from the DSL line as the clock for the serial interface.
— The X.21 modem that is configured as Internal must als o b e
DCE, but if it is an External/Network clock, then the modem must be configured as DTE.

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 software is u pgraded by waiting for the Reset Mode mes sage. The n, the user can send an Intel HEX file supplied by Patton. After the VT100 emulator has finished sending this file, the 3088RC will respond with a mes-sage stating how many errors were detected. The user may then set the DIP switches to the desired configuration and power cycle the unit to run the upgraded software.
Configuration Reset to Factory Defaults
To recover from a forgotten password, the user may reset the unit to its factory configuration. After seeing the Reset Mode mess age, the user should type the ‘*’ key. This will result in a ‘:’ prompt. At the prompt, the user should enter th e comman d reset. This w ill res tore the unit to th e fac­tory configuration. The unit can then be restarted with the settings in place.
3.5 CONFIGURING THROUGH THE CONSOLE
The 3088RC offers a console command line interface. To access the console, use a VT100 emulator configured to 9600 bps, 1 stop bit, no parity, and XON-XOFF flow control. Use the 1001CC to access the con­sole. Type CTRL+B <address> <enter> to activate the console. Log into the unit using the default password. No username will be needed.
Note Log in with the default password superuser.
You can configure the following variables through the console:
Password: The password used to login to the console.
Circuit ID: The circuit ID communicated to other units via EOC. EOC (Embedded Operations Channel) is an out-of-band channel specified in the G.991.2 standard for SHDSL. We use standard EOC messages for our remote loopback. The 3088RC also supports proprietary EOC messages that allow a 3096RC to configure it.
Clock Mode: The following options are available:
— Internal: The internal oscillator in the 3088RC provides the
clock to both the serial/T1/E1 and DSL interfaces.
— External: The serial interface provides the clock for the DSL
interface (V.35, X.21). It must be set to DTE for the X.21 inter­face. (This mode is invalid for the Ethernet model).
— Receive Recover: The 3088RC recovers the clock from the
DSL interface and provides it to the serial/E1 interface.
