Per Cisco for T3 Interface loopback testing:
Syntax Description
dte
Sets the loopback after the LIU toward the terminal.
local
Sets the loopback after going through the framer toward the terminal.
network {line | payload}
Sets the loopback toward the network before going through the framer (line) or after going through the framer (payload).
remote
Sends a far-end alarm control (FEAC) to set the remote framer in loopback.
I am sorry, but I am trying to understand the components involved in the testing.
It the path of traffic from
Terminal-->LIU-->Framer-->network?
What is the difference between the DTE test and the Local test?
What is the LIU and the Framer?
These are both testing the local equipment before hitting the "network", but are not actually testing any connection to the providers equipment (which would include my cabling), is this correct?
What is the "Line" test actually testing and what is the "Line" and what is the "Payload"?
Would these be testing my cabling going through the providers equipment local to me?
The "Remote" is the only one that seems clear to me, which is putting the remote port in loopback, which would test my cabling, the local providers equipment and remote providers equipment?
Is this correct?
Which would include the customers remote cabling?
