qbTimingOutLineRef

Module: QB-TIMING-MIB

OID (symbolic): QB-TIMING-MIB::qbTimingOutLineRef

OID (numeric): 1.3.6.1.4.1.4323.2.11.1.1.7

Node type: OBJECT-TYPE

Type: InterfaceIndexOrZero

Access: read-write

Description: The value of ifIndex corresponding to the port interface that provides a line reference for the external timing outputs. The object is changed in conjunction with 'qbTimingOutputMode'. When 'qbTimingAdminStatus' is set to 'freerun' this object is irrelevant and the agent returns 0. Note: this object is relevant only for main and au-1/au-2 and au-7/au-8 slots.

What is qbTimingOutLineRef?

This read-write object holds the ifIndex of the port interface, restricted to the main, au-1/au-2, or au-7/au-8 slots, used as the line reference for the system's external timing outputs. It is changed together with qbTimingOutputMode, and the agent returns 0 when the timing mode is freerun because no output line reference applies. For example, an admin enabling BITS output distribution would set qbTimingOutLineRef to the ifIndex of the au-1 slot port before setting qbTimingOutputMode to lock(2).
