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:
none
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.
payload
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.
facility
The received signal at this interface does not go
through the device (minimum penetration) but is
looped back out.
other
Loopbacks that are not defined here.
terminal
The transmitted signal at this interface is
looped back and received by the same interface.
What is transmitted onto the line is product
dependent.
dual
Both acDs1LineLoop and acDs1InwardLoop will be
active simultaneously.
