Setting
Specifies the loopback mode.
Valid values are as follows:
no-loopback—(the default) The interface is
operating normally.
fe-loopback—Front-end loopback. Received
data is transmitted back to the far end by the
transceiver at the near end.
line-loopback—The received data is looped back
to the far end without doing any reframing of the
T1 or E1 frame.
remote-loopback—Remote payload loopback.
The received payload on the line is transmitted
back to the far-end by a reframing of the payload
at the near-end transmitter.
local-loopback—Local loopback. The
transmitted data is looped back to the near-end
receiver by the local transceiver.
Specifies whether the unit obtains the system clock
signal from the port.
Valid values are as follows:
eligible—Specifies that the line can be used as
the master clock source.
not-eligible—Specifies that the line cannot be
used as the master clock source.
For more information, see "Configuring system
clocking (optional)" on page 6-19.
Assigns a clock priority to an interface. When
multiple interfaces are eligible to be the clock source
for synchronous transmissions, the Stinger MRT uses
the value you specify to select an interface as the
master clock source. If multiple interfaces are eligible
to be the clock source and each interface has an
equal Clock-Priority value, the Stinger MRT chooses
a clock source at random.
Specify one of the following values:
high-priority—Specifies the highest priority.
The Stinger MRT chooses an interface with this
priority setting as the clock source over other
interfaces with a lower priority. If more than one
interface has the highest priority, the first
available interface becomes the clock source.
