Video Teleconferencing System (VTC) General: The DSN provides an implementation of non-MLPP and MLPP ISDN
that can be used for end-to-end digital VTC systems in secure or non-secure modes at any level of precedence. The DSN
uses an intelligent signaling network and a limited set of user-network interfaces. The DSN implementation of ISDN will
allow for the integration of voice, data, video, text, and graphics communications. The DSN is capable of two ISDN
standard interfaces identified as:

Basic Rate Interface (BRI)
Primary Rate Interface (PRI)

Video teleconferencing systems and endpoints connected to the DSN may incorporate the following:

Camera, monitor, microphone, and speakers
Codec
MCU
H.323 to H.320 Gateway
Cryptographic device/cryptographic device bypass unit
Other similar equipment

H.323 assured service has not yet been defined, thus the H.323 interface has no assured service capabilities. This
interface can only serve DoD, non-DoD, non-governmental, and foreign government users having no missions or
communications requirement to ever originate or receive C2 VTC communications under existing military scenarios. These
users are provided access to the DSN for the economic or policy benefits of the DoD, when it is not in conflict with local
PTT ordinances. Since H.323 does not provide assured services during a crisis or contingency, users’ access to the DSN
will be on a best effort basis. Therefore, C2 VTC users and special C2 VTC users are not authorized to be served by an
H.323 interface. These devices may be implemented as individual components or be integrated with one or more other
components as a system. The terms VTC, VTC system(s), and VTC end point(s) are used synonymously. VTC
systems/end points are typically connected to the DSN via an IAS (see UCR 2008, Section 5.2.12.7, Integrated Access
Switch/System Requirements, for DSN IAS requirements) or a Terminal Adapter (see UCR 2008, Section 5.2.12.3,
Customer Premises Equipment Requirements, for DSN TA requirements). This requirement also addresses VTC
systems/end points that have an integral IAS or TA for connection to the DSN. In addition to the requirements specified in
this UCR 2008 section, VTC systems/devices that have integral IAS/TA functions shall conform to the stated requirements
