Allocation of bandwidth is shared among the Remotes in an STDMA group.
Depending on the number of Remotes in a network, a Hub may have multiple
burst controllers, each with its own set of Remotes. This is accomplished by
assigning a unique Group ID number to each controller and its associated
Remotes.
Note: The STDMA Group ID number and the Network ID number are indepen-
NOTE
dent. There can be multiple STDMA groups within a single network.
To set the Group ID for an SLM-5650A, enter the specified number for the
associated group; range is 1–255 (figure 3-16). Click the Submit button.

Cycles Per Burst Map

This parameter, which appears for all Hub types except Dynamic Cycle and
GIR, displays the number of spin cycles that will occur prior to each broadcast
of the Burst Map by the burst controller to the Remotes. One cycle is the
amount of time it takes for all Remotes in a group to burst on the common chan-
nel. The burst map provides each Remote with its allocated bandwidth and posi-
tion in the cycle.
For Dynamic Cycle and GIR configurations, the number of cycles is automati-
cally set to one in order to ensure optimum performance for these Hub types.
To modify this parameter from the Hub SLM-5650A, enter a value from 2–20 in
the Cycles Per Burst Map field, then click the Submit button as shown in
figure 3-17.
