Software Upgrades 
The software is upgraded by waiting for the Reset Mode message. Then, 
the user can send an Intel HEX Þle supplied by Patton. After the VT100 
emulator has Þnished sending this Þle, 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 conÞguration and power cycle the unit to 
run the upgraded software. 
ConÞguration Reset to Factory Defaults 
To recover from a forgotten password, the user may reset the unit to its 
factory conÞguration. 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 conÞguration. 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 conÞgured to 9600 bps, 1 stop bit, no 
parity, and XON-XOFF ßow 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 conÞgure 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 speciÞed 
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 conÞgure 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.
