To configure the Operational States of the Hub Site unit
1. Click the Enabled check box
2. Click the Configure button
The Hub Site Configuration dialog box with the current status of the
ODUs is displayed.
3. Select the type of unit configuration from the drop-down list.
4. Select the appropriate RFP radio button. Some RFP options may be dis-
abled depending on the bandwidth previously selected.
Note
Continue Transmission is intended to work if there is no HSM pulse. If a
wrong HSM pulse is detected, a FA4800 will resync, adapting to the HSM
RFP and continue whereas FibeAir 2000 may stop.
