Set STDMA Flag
It is important for the operator to set the STDMA flag on the network burst
controller(s). The VMS sets the flags for the other network devices automati-
cally.
1. Right-click on the BC demodulator and select Properties from the drop-
down menu (figure 3-49).
Figure 3-49 Hub BC Demodulator Properties menu command
2. The dialog appearance with the correct setting is shown in the figures below.
• For a CDM-570/570L Burst Controller, select the Modem dialog, then
select the STDMA radio button, figure 3-50.
• For an SLM-5650A Burst Controller, select the Burst Controller check
box, figure 3-51.
Note for SLM-5650A Hub BC redundacy configurations: Do NOT select
the Burst Controller check box on redundant units. This flag is
unnecessary and may cause network communication problems. Should a
failover occur, the redundant unit will be automatically configured
exactly as the online unit, and this flag will be set correctly at that time.
