• Question 295:

  Click the Exhibit button.

  

  When the G. series card Rx interface at "A" in the diagram loses it's receive signal, what occurs?

  A. The G. series card at "A" reports link down and sends an AIS alarm upstream.
  B. The G. series card at "A" reports link down, but the SONET path remains up.
  C. The Tx signal on the G. series card at either end of the circuit is shut off, causing the device connected to each G. series card to report link down.
