Adding a Pseudowire Profile
To add a pseudowire profile:
Definition
Select Enable or Disable to enable or disable payload suppression. When
enabled, the payload is suppressed upon incoming TDM failure.
Enter a value between 96 and 127. This value is used to distinguish
between signaling and data types. The default value is 96.
Enter the byte pattern transmitted on DS0 channels when packets
overflow or underflow the jitter buffer (from 0 to 255).
Enter the CAS alarm pattern transmitted on the E1/DS1 interface when
packets overflow or underflow the jitter buffer (from 0 to 15).
Reserved for future use.

Reserved for future use.
Select Enable or Disable to enable or disable loss of packet
synchronization (LOPS) detection. The default value is Enable.
Enter the number of consecutive packets with sequential sequence
numbers required in order for the system to exit a loss of packet
synchronization state (LOPS), from 1 to 10. The default value is 2.
Enter the number of consecutive missing packets required in order for the
system to enter a loss of packet synchronization state (LOPS), from 1 to
15. The default value is 2.
Enter the time period (in milliseconds) the system uses to compute the
average packet loss rate in order to detect excessive packet loss (1-
65535). The default value is 3000.
Enter the alarm threshold (in percentage) for excessive packet loss (1-
100). The default value is 50.
Enter the amount of time (in milliseconds) the system waits after a fault
condition exists before raising an alarm (1-65535). The default value is
2500.
Enter the time (in milliseconds) the system waits before clearing an alarm
once the alarm condition has ended (1-65535). The default value is
10000.
Enter the percentage of missing packets detected within a one second
window that will cause SES to be counted.
