End-to-End BERT for CESoPSN Bundles Overview

This topic provides an overview of how to set up end-to-end BERT for CESoPSN bundles.

Figure 1 shows the normal data flow through the network. BERT is disabled.

To set up end-to-end BERTS for CESoPSN bundles:

  1. To send BERT transmissions to the network, start BERT injection on each CESoPSN bundle toward the IP network as shown in Figure 2.

  2. To receive BERT reception from the network, start BERT reception on each bundle from the IP network as shown in Figure 3.

The result is that end-to-end BERT transmission and reception are running as shown in Figure 4.
