This section describes connector-level configuration and status
commands applicable to Ultra-WAN CSU/DSU connectors on a model
S590 PathBuilder switch.
FLUSH [!<path>] -PAth ConnCounters
This command resets all of the ConnCounters statistics collection, so that
collection can begin at a known point in time.
LPBCK !<path> -PAth RmLnLpck | RmPyldLpbck | STOP
This command allows the receive path of the Ultra-WAN CSU/DSU
connector to be looped back to the transmit path. RmLnLpck specifies a
remote line loopback. RmPyldLpck specifies a remote payload loopback.
Loopback mode runs continuously until the stop setting is issued.
The LPBCK command has other parameters than those shown here.
These other parameters are for factory test only and should not be used.
