This value contains information about loopbacks established by a manager and remotely from the far end.

dsx1LoopbackStatus is a bit map represented as a sum; therefore, it can represent multiple loopbacks simultaneously.

The bit positions are:

Bit | Value
--- | ---
1 | dsx1NoLoopback
2 | dsx1NearEndPayloadLoopback
4 | dsx1NearEndLineLoopback
8 | dsx1NearEndOtherLoopback
16 | dsx1NearEndInwardLoopback
32 | dsx1FarEndPayloadLoopback
64 | dsx1FarEndLineLoopback

Note: The NMS SNMP agent always returns dsx1NoLoopback because loopback is not supported.
