Chapter 8 Interface and Subinterface Management
ATM/E3 Interface Management Window
E3
The E3 area contains the following information:
• Clock Source—Source of the transmit clock.
– loopTiming—Indicates that the recovered receive clock is used as the transmit clock.
– localTiming—Indicates that a local clock source is used or that an external clock is attached to
the box containing the interface.
•
E3 Framing—Describes E3 framing. The following values are possible:
– g832adm
– g751adm
– g751plcp
• E3 Scrambling—Indicates whether or not E3 scrambling is enabled on the interface. Scrambling
assists recovery of the clock by the receiver.

including those that were discarded or not sent.
•
In Packets/Sec—Five-minute exponentially decayed moving average of input packets per second.
• Out Packets/Sec—Five-minute exponentially decayed moving average of output packets per second.
