This type is not a standard SMI/SNMP base type and is not defined as a documented TEXTUAL-CONVENTION in this MIB.
It was extracted as raw syntax from the source MIB file and could not be resolved to a known type definition.
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.
