End-to-End BERT for CTP Bundles Overview

 

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

Figure 18 shows the normal data flow through the network. BERT is disabled.

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

  1. To send BERT transmissions to the network, start BERT injection on each CTP bundle toward the IP network as shown in Figure 19.

  2. To receive BERT reception from the network, start BERT reception on each bundle from the IP network as shown in Figure 20.

The result is that end-to-end BERT transmission and reception are running as shown in Figure 21.
