cifLLoopback

This object specifies the type of loopback to be established.
This object is required in order to complete the creation of a
row in this table. It cannot be modified when the cifLRowStatus
is active(1).
              
Possible values are :
                       
farEndLineLoopback(1): This loopback occurs at the CPE upon
         receiving a special code from the
         device which initiates the loopback.
         Upon receiving the loop activation request
         code, CPE enters a Line loop mode in which it
         returns the entire line back to the initiator.
         The CPE will continue to return the data
         back to the initiator until it receives
         a loopback deactivation request code.
              
farEndPayloadLoopback(2): This loopback occurs at the CPE
         upon receiving a special code from the
         device which initiates the loopback.
         Upon receiving the loop activation request
         code, CPE enters a Payload loop mode in which it
         returns the Payload of the received data back 
         to the initiator.
         The CPE will continue to return the data
         back to the initiator until it receives
         loopback deactivation request code. 
               
remoteLineLoopback(3): This loopback is established at the 
         Near-end. In this loopback the entire line is looped 
         back to the Far-end with a) bit-sequence integrity 
         maintained,
         b) no change in framing, and c) no removal of bi-
         polar violations.    
              
remotePayloadLoopback(4): This loopback is established at 
         the Near-end.  In this loopback the signal that is 
         returned to the Far-end consists of the payload of 
         the received signal (with bit sequence integrity 
         retained) and newly generated framing information.                             
               
localLoopback(5): This is also known as metallic loopback.
         This loopback is used for checking the
         internal circuitry of the T3/E3, T1/E1 
         device.  Only for physical lines.
