Which of the following is a minimum threshold condition that will cause a CTS to drop a call?

A.
10 seconds of 1 percent packet loss

B.
10 seconds of 10 percent packet loss

C.
10 seconds of 100 percent packet loss

D.
60 seconds of 10 percent packet loss

E.
180 seconds of 10 percent packet loss

Explanation:
A Cisco TelePresence System (CTS) will drop a call after 180 seconds, or three minutes, of 10percent packet
loss. In addition, a CTS will drop a call after 30 seconds of 100 percent packet loss.
After a CTS experiences 1percent packet loss for 10 seconds, the CTS will write an alarm to syslog, generate a
Simple Network Management Protocol (SNMP) trap, and display an onscreen message for 15 seconds. Alarms
and SNMP traps will continue to be generated for the next five minutes without any corresponding onscreen
messages.
After a CTS experiences 10percent packet loss for 10 seconds, the CTS will write an alarm to syslog, generate
an SNMP trap, and display an onscreen message for 15 seconds. Alarms and SNMP traps will continue to be
generated for the next five minutes without any corresponding onscreen messages.
After a CTS experiences 10percent packet loss for 60 seconds, the CTS will write an alarm to syslog, generate
an SNMP trap, display an onscreen message for 15 seconds, and downgrade the video quality.
Quality is downgraded by reducing motion handling; resolution is not affected.
