Description: Indicates the loopback status of the far end DS3,DS1
when remote DS1 loopback request is initiated.
The remote DS1 loopback is initiated by setting  dsx3SendCode
object to dsx3SendDS1LoopCode(5).
For unchannelized DS3 applications DS1s are unassigned.

Following table lists the mapping of Bit position to
DS1 or DS3 lines and the value.
