Model 3088 Series User Manual 2 • Configuration
S2-6 through S2-8: Line Type (Models 3088/K and 3088/T)
The RocketLink-G has two different line types, T1 and E1. T1 has three different settings, and E1 has five dif-
ferent settings.
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 pass-
word. 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 con-
figure 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).
