Your Action
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.
