DESCRIPTION
Sets the E1 physical loopback testing
mode for the specified E1 port.
lpbkmode:
0 (None LPBK): stop the previous E1
loopback test
1 (Line LPBK): return all physical or
electrical signals received from the
remote connected device
2 (In-ward LPBK): force all transmitted
data to return to this port
3 (Payload LPBK): return all data
received from the remote connected
device
Displays the E1 physical loopback testing
mode setting of the specified E1 port.
Performs an OAMF5 loopback test on the
specified subscriber port or PVC.
the specified IMA group.
Performs an IMA loopback test for the
specified IMA group.
link: the number of an E1 link in the
same IMA group
pattern: This is a 2-digit hexadecimal
number the IMA line card will add into
IMA Control Protocol (ICP) cells before
sending them to the remote connected
device. The remote device should also
send ICP cells with this number to the
IMA line card. Otherwise, there is an IMA-
layer connectivity problem between these
two devices.
Displays the IMA loopback testing
settings for the specified IMA group.
Perform the specified Metallic Line Test
on the specified VoIP line card port.
all: perform all tests
vac: test AC voltage
vdc: test DC voltage
rload: test load resistance
riso: test isolation resistance
cap: test capacitance
ren: test ringer equivalent number
ring: test ring voltage
metering: test metering voltage
force: perform the test(s) immediately
even if the specified VoIP line card port is
in use.
Displays the result of the Metallic Line
Test last performed on this port.
Turns the test relay in/out function on/off.
