iDSL Port Configuration window 138
Models 2616RC, 3096RC & 3196RC Admin Reference Guide 10 • iDSL (Model 3196RC)
• lineLoop(3)—The T-DAC’s iDSL port will operate in line loopback mode as shown in figure 72. For the
CPE remotely connected to this port, you can use lineLoop(3) mode to test the iDSL link from the CPE to
the T-DAC and back to the CPE.
Figure 72. Line loopback
When a CPE transmits data to a T-DAC’s iDSL port with Test Mode defined as lineLoop(3), the iDSL port
will loop the data back to the CPE.
• off(0)—The default value for Test Mode. Appears as a display-only value.
Test Pattern (idslPattSelect)
Configurable, but only when the value of State is one of the following:
• dataMode(6)
• localLoop(1)
• remoteLoop(2)
Otherwise, display-only with a value of off(0).
Until the iDSL link is established, the iDSL Port Status table will display a dash (-) in the Test Pattern column
using display-only format. Once the iDSL link is established and the port state changes to datamode(1), the
Test Pattern drop-down menu will appear.
The Test Pattern parameter defines which test pattern the T-DAC will generate and transmit. The T-DAC’s will
transmit the selected test pattern to the destination port defined by the value of Test Mode (see section “Test
Mode (idslTMSelection)” on page 136). To define the Test Pattern, select one of the following values from the
drop-down menu, then click the Submit button:
• off(0)
• patt511(1)
• patt511E(2)
• patt2047(3)
• patt2047E(4)
• pattQRSS(5)
• pattQRSSE(6)
Once you click the Submit button, the Test Pattern column will display the newly defined value in display-
only format, together with a check box labelled Off. To disable the test or to change the test pattern, click the
Off check box and click the Submit button.
