To display information about the port settings on an ATM port:
The following is an example of the information that is displayed with the command listed
above (for a PDH PHY interface):
• Port Type Shows the type of PHY interface for the port.
• Xmt Clock Source Shows the timing source for the port.
Local indicates the onboard clock oscillator as the
timing source.
Loop indicates the receiver input as the timing
source.
• Scramble Mode Shows the scramble/descramble mode for the
port.
None indicates no scrambling.
Payload indicates scrambling of the payload
only.
Frame indicates scrambling of the stream only.
Both indicates scrambling of payload and stream.
• Line Coding Shows the particular DS1/T1 and DS3/T3 coding
convention.
• Cell Mapping Shows the format used to map ATM cells.
Direct indicates direct cell mapping.
Plcp indicates physical layer convergence
protocol mapping.
• Framing Shows the type of framing scheme.
cbit-parity is used for T3 framing.
m23 is used for T3 framing.
