Configuring Serial Loops for CTP Bundles (CTPView)

 

Serial loops will run on transparent circuits only if the transparent circuits use the SD and RD signals to transport data.

To configure serial loops using CTPView:

  1. In the side pane, select Bundle > Diagnostics.
  2. Click Bit Error Rate Tester.
  3. Run your mouse over the MouseOver to Select a Port to Display bar.

    A list of bundles configured on the CTP device appears.

  4. In the table of bundles, select the bundle for which you want to configure a serial loop.
  5. Configure the serial loop as described in Table 60.

FieldFunctionYour Action

Serial Loop

Specifies the direction of the serial loop or removes the serial loop.

Select one:

  • None—Removes the serial loop.

  • To Net—Creates a loop toward the network. Data arriving from the IP network destined for the serial interface is looped back to the IP network and remote customer device. The data is still transmitted from the IP network to the serial interface, but data from the serial interface to the IP network and remote device is blocked.

  • To I/F—Creates a loop toward the customer device attached to the serial interface. Data arriving from the serial interface that is destined for the IP network is looped back to the serial interface. The data is still transmitted from the serial interface to the IP network, but data from the IP network to the serial interface is blocked.
