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 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 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 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 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 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 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.
