Enumeration
This variable represents the desired loopback
configuration of the DS1 interface. Agents
supporting read/write access should return
inconsistentValue in response to a requested
loopback state that the interface does not
support. The values mean:
dsx1NoLoop
not in the loopback state. A device that is not
capable of performing a loopback on the interface
shall always return this as its value.
dsx1PayloadLoop
the received signal at this interface is looped
through the device. Typically, the received signal
is looped back for retransmission after it has
passed through the device's framing function.
dsx1LineLoop
the received signal at this interface does not go
through the device (minimum penetration) but is
looped back out.
dsx1OtherLoop
loopbacks that are not defined here.
dsx1InwardLoop
the transmitted signal at this interface is
looped back and received by the same interface.
What is transmitted onto the line is product
dependent.
dsx1DualLoop
both dsx1LineLoop and dsx1InwardLoop will be
active simultaneously.
