DEFINITIONS

Uses Primary timing reference.

Uses clock derived from incoming receive fiber (also known as Line-Timing).

Outputs DUS (Do not Use for Sync) in the S1 byte of the SONET overhead.

Enables a protection switch of the traffic if the input signal strength drops below tolerable levels set by the user in the BER threshold selection.

Defines the number of bit errors the port can incur before a signal degrade occurs and generates an alarm message and probably protection switch.

Synchronous Optical Network, US standard for transporting data over fiber.

Synchronous Digital Hierarchy, European standard for transporting data over fiber.

No loopback is requested or active.

A loopback has been activated sending the signal back to the terminal side.

A loopback has been activated sending the signal back to the facility side.

Not configurable by user.

Not configurable by user, dependant on card type inserted.
