optTransportLoop

Module: ERI-DNX-STM1-OC3-MIB

OID (symbolic): ERI-DNX-STM1-OC3-MIB::optTransportLoop

OID (numeric): 1.3.6.1.4.1.644.2.4.2.7.2.3.1.6

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Indicates the loopback status of the Stm1Oc3 Transport for this device. off (0) - indicates Transport loopback is disabled terminal (1) - The optical line interface transmit driver is looped back to the optical receiver. Ultimately the payload is reflected back to the Switch Fabric and the PCM Highway of the DNX Backplane. facility (2) - The Fiber Optic path is looped back to the facility. pathFacility (3) - The Stm1Oc3 incoming data (Rx) is transmitted back to its source via the Tx path. The bus that interfaces to the mappers is in loopback, and the entire payload is returned to its source with a refreshed frame structure.

What is optTransportLoop?

Sets the loopback mode for this Transport interface: off disables it, terminal loops the optical transmitter back to the receiver toward the switch fabric, facility loops the fiber path back out, and pathFacility returns incoming data to its source with refreshed framing.
