Connecting to networks of different classifications simultaneously incurs the risk of data from a higher classification being released to a network of a lower classification, referred to as a "spill". It is imperative that networks of differing classification levels or with differing handling caveats not be interconnected at any time. Separation in a multinetwork VTC system is maintained by the use of an A/B, A/B/C, or A/B/C/D switch that meets requirements for channel isolation or by manual connection of the CODEC to one network at a time.
Review the VTC system architecture to verify that an approved A/B, A/B/C, or A/B/C/D switch is present and properly cabled. Alternately, validate that the VTC CODEC is manually connected to one network at a time through the use of a single patch cord. If neither is in place, this is a finding.
Obtain and install an approved A/B, A/B/C, or A/B/C/D switch. Alternately, manually connect the VTC CODEC to one network at a time through the use of a single patch cord.
