Parameter Definition
Payload Suppression Admin Select Enable or Disable to enable or disable payload suppression. When
enabled, the payload is suppressed upon incoming TDM failure.
Payload Type Enter a value between 96 and 127. This value is used to distinguish
between signaling and data types. The default value is 96.
Timeslot Fill Pattern Enter the byte pattern transmitted on DS0 channels when packets
overflow or underflow the jitter buffer (from 0 to 255).
CAS Alarm Bit Pattern Enter the CAS alarm pattern transmitted on the E1/DS1 interface when
packets overflow or underflow the jitter buffer (from 0 to 15).
RTP Header Use Reserved for future use.
RTP Timestamp Mode Reserved for future use.
RTP Timestamp Factor Reserved for future use.
LOPS Detection Admin Select Enable or Disable to enable or disable loss of packet
synchronization (LOPS) detection. The default value is Enable .
Consecutive Sequential
Packets Threshold 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.
Consecutive Missing Packets
Threshold 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.
Packet Loss Window 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.
Excessive Packet Loss
Threshold Enter the alarm threshold (in percentage) for excessive packet loss (1-
100). The default value is 50.
Alarm Raise Threshold 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.
Alarm Clear Threshold 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.
SES Threshold Enter the percentage of missing packets detected within a one second
window that will cause SES to be counted.
