An IP-based VTC system implementing a single CODEC supporting conferences on multiple networks having different classification levels (i.e., unclassified, SECRET, TOP SECRET, TS-SCI) must support Periods Processing by connecting the CODEC to one network at a time, matching the classification level of the session to the classification level of the network.

Description

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.

Check Text ( C-49173r4_chk )
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.

Fix Text (F-48600r3_fix)
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.
