Switching from Primary Link to Secondary Link
Switching from primary link to secondary link will occur following:
• Loss of the primary air interface due to sync loss
• Loss of the primary air interface due to failure of the receiver to
acquire expected E1/T1 data during a period of 24ms
• The Primary equipment (either ODU or IDU, local or remote) is pow-
ered off
Following the switch from the primary to the secondary link, the primary
and secondary link Manager main windows should look like this:
