In the Holdoff Time field, specify the amount of time the system waits when bandwidth
degradation occurs, before transmitting a message. If the bandwidth is below the nominal
value when the holdoff period ends, the system starts transmitting messages.
9.
In the MEL field, select the Maintenance Level in the messages.
10.
In the Tx Period field, specify how often messages are transmitted when bandwidth is below
the nominal value. Options are:
o
4 – One second.
o
5 – Ten seconds.
o
6 – One minute.
