Determining Number of Blocked Data Streams

Before running the Dialogic SCX160 Configuration Program, determine the number of data streams to be blocked in the multi-node system. To determine this number, enter the following information into Table 21. Dialogic Blocking Configuration Chart and make the indicated calculations:

Node #
Resource to be blocked in this node
Boards installed in this node
Total number of time slots to be blocked in this node. Determine this number as follows:
1. Locate the model number of an installed board in Table 20. Time Slots Required Per Board and record the Time Slots Required quantity for the resource to be blocked in the Time Slots Blocked column of Table 21. Dialogic Blocking Configuration Chart. See Table 22. Example Blocking Configuration Chart for a sample chart.
2. Repeat step 1 for each board installed in this node.
3. (optional) Add an unused/reserved-for-future-expansion entry and a corresponding number of time slots to be blocked. Reserving additional time slots may enable future expansion without reconfiguring the system.
4. Add all the Time Slots Blocked entries for this node to get the sum.

Divide this sum by 64 to get a quotient.

Round up this quotient to the next highest integer.

Enter this integer in the Data Streams Blocked column as the total number of data streams that must be blocked in this node.

Repeat procedure from Step 1 for each node.

Select the largest numerical value listed in the Data Streams Blocked column and use/enter this value as the Number of data streams to be blocked in EACH node.
