• Local Loopback (LLB): Can be used to check the source of a certain problem.

receives its own signal while the loopback is connected. If it does, the problem is
external.

AAL1 Stream Application Mode
In this application, the data stream at the selected data rate (n ׳64 kbps) is
transferred transparently. Therefore, the AAL1 stream mode supports any Layer 2
protocol and only one connection can be defined on the port.
Before you can begin configuring the Data Port - AAL1 Stream, you must first
configure the Data port application.
