<portlist>
< f5>
<vpi> <vci>
This command has the IES-1248-51 perform an OAMF5 loopback test on the specified ADSL
port(s).
The following example has the IES-1248-51 perform an OAMF5 loopback test on ADSL port
1's PVC at VPI 0 and VCI 33.

You can specify a single ADSL port <1>, all ADSL ports <*>
=
or a list of ADSL ports <1,3,5>. You can also include a range of
ports <1,5,6~10>.
Use f5 to perform an OAMF5 loopback test on the specified
=
DSL port. An Operational, Administration and Maintenance
Function 5 test is used to test the connection between two DSL
devices. First, the DSL devices establish a virtual circuit. Then
the local device sends an ATM F5 cell to be returned by the
remote DSL device (both DSL devices must support ATM F5 in
order to use this test).
When you perform an OAMF5 loopback test, specify a VPI/
=
VCI.
