Appendix B - Dialogic SCX160 Configuration Program

Step-by-step procedures for running the Dialogic SCX160 Configuration Program are presented in this appendix. The Dialogic SCX160 Configuration Program is used to select the type of configuration, i.e., Non-Blocking or Blocking. The program is used to determine the number of data streams that need to be allocated to the node, and it is used to select the SCbus data streams that will be blocked from the SCxbus in the case of a Blocking Configuration. For a description and an example of SCbus time slot blocking, refer to Section 2.3.  Blocking Data Streams.

The following considerations apply to blocking:

• Only the time slots for one resource (e.g., voice, analog or digital) can be blocked per node.
• When blocking time slots for a resource in a node, the number of data streams blocked must include all the time slots being used for that resource (e.g., if 5 D/240SC-T1 boards reside in Node 1 and voice resources are blocked, then two data streams (128 time slots) must be blocked from the SCxbus because the voice resources on these boards require 120 voice time slots).
• The time slots for a different resource can be blocked in each node (e.g., Node 1 can block time slots for the voice resource and Node 2 can block time slots for the digital resource).
• The number of data streams blocked from the SCxbus must be the same for each node in the system. This number must be equal to or greater than the largest number of data streams to be blocked in any node.

NOTE:

The number of time slots used by a resource in a given node can be calculated from Table 20.  Time Slots Required Per Board and the configuration information entered on the Dialogic Node Configuration Chart in the SCX160 SCxbus Adapter Package Release Notes when the SCX160 SCxbus Adapter was installed.
